Questions Mix Questions : Total Topic 1 Case Study: Topic 1 Title : Case Study Alpine Ski House Alpine Ski House is a company that owns and operates hotels, restaurants, and stores. Currently, the company uses the following software and interlace: •Property management software (PMS) to manage hotel rooms •On-premises accounting software to generate sales invoices and create purchase orders •An API that allows restaurants and stores to obtain necessary information Restaurants and stores use standalone software for point of sale (POS) devices. Each day, the POS terminals generate a text file of sales data and save the files in a serval folder. An account assistant must manually import the files to the current software tables to be processed by the system. The general manager receives several reports monthly from department managers. The reports take too much time to prepare. The company is moving from a different system to 8usiness Central online to manage the whole company. The company plans to increase efficiency in every department by using APIs to obtain or share information between the different systems. Each department involved in purchasing must be able to make purchase requests automatically and easily. The departments do not need access to the full ERP management system. Alpine Ski House requires the development of several extensions for the planned improvements. Business Central design patterns must be used to develop all extensions. Alpine Ski House must develop the following pages: •Pages that provide multiple configurations in a multistep dialog, like a wizard, to provide required information when the extensions are first installed •Department-specific Role Center pages to show relevant information and pages with additional information The IT department plans to use Power 61 to analyze departmental information. The database must be

The housekeeping department requires the following to increase efficiency and help avoid data entry errors: •A Housekeeping Role Center to minimize navigation to relevant areas In Business Central online and to show relevant information in it •Pages to embed into a new Room page to show additional information about the Room entity •A table named Room Incident for the housekeeping team to enter room issue information •A Housekeeping canvas app that connects to an extension The department requires the development of an extension with a new API page named RoomsAPI. •The housekeeping team will use RoomsAPI to publish room details, update when work is complete, or provide repair notifications from the canvas app. •This custom API page must expose a custom table named Rooms and have an ID 50000. The table must be able to update from the PMS. The PMS team must know the end to connect to the custom API. •A developer provides the following details for the API page: APIPublisher = 'alpine'; APIGroup - 'integration'; APIVersion - 'v2.6'; fntityName 'room'; EntitySetName = 'rooms'; •The extension must be published in Business Central online and include a list page named Room List that includes all hotel rooms. •Installation or updates to this extension must meet the following requirements: oSome web services must be published automatically. oThe version of the specified application's metadata must be obtained in AL language. oThe code required to perform tasks cannot be accessible from other parts of the application. The Room Incident table information must include the following fields: •Incident entry: An incremental number •Room No.: A room from the Room table •Incident Date: The work date oThe table definition in the Room Incident table must autofill the Incident Date when the housekeeping team

4. inserts a new record, o The value for Incident Date must be the work date configured in the Business Central online client. •Status: Includes the following options lo identify the status of the incident: oOpen: When the Room Incident is created oIn Progress: When someone starts repair work oClosed: When the incident is solved •Incident Closing Date: Auto-updating field (when the status passes to Closed, the field will update with the work date) •Incident Description: Text •Image. Media data type oThe stored picture must be downloadable from a menu action. oA Room Incident page must be developed to contain the download action. To increase efficiency, the new system must manage the generated data from the restaurants and stores directly by using the API on the POS terminals. •The company requires a code unit called from a job queue to read the information from the POS terminal APIs. •The POS terminal information must be stored in a table named POS Information, have an ID 50100. and be editable on a page. •The account manager requires an option on the menu of the page to run the process manually. To analyze the information received from the POS terminals, the company requires: •A custom API named ticketAPI to export the information to Power BI •Use of the Read Scale-Out feature to improve database performance The purchasing department requites a new entity in Business Central online to log non-conformities of goods received from vendors. The entity must be set up as follows: •The non-conformity entity must have two tables: o a header with common information o one or more lines with the detailed received items that are non-conforming •The entity requires a page named Non-conformity and a subpage named Non-Conformity Lines to store the information.

5. When a purchase order with incorrect quantity 01 quality issues is received, the entity must create a non-conformity document in the system. The following information must be nick the document: •Non-conformity Number: must use the No. Series table from Business Central online to manage this field and use these features: oAlphanumeric values oNumber format that includes "NO and the year as part of the number: for example, NC24-001 •Non-conformity Date: stores only the creation date •Vendor No.: stores the number of the vendor that sent the items; only vendors from the company must be included •Owner: code of an employee defined in the company •Receipt No.: must meet the following conditions: oBe an existing receipt No. oBe received from the vendor indicated in the Vendor No. field •Comments: can include comments with rich text and pictures to illustrate quality problems » •Status: includes nonconformity statuses, such as: oOpen oNotified oClosed •Lines must contain the following details: oItem No.: item received (for existing inventory items only) oDescription: item description 0 Quantity: non-conforming quantity 0 Non-conformity Type: Quality Quantity Delivery date The serial numbers of the non-conformities and the period in which they can be created must be in a configuration table and its corresponding page to allow them to be modified for the users.

Questions You create the following Vendor table and Item table in Business Central. You require the following data set to assign vendors to items.

10. You need to create a query to assign the vendors. Which three code blocks should you use to develop the solution? To answer, move the appropriate code blocks from the list of code blocks to the answer area and arrange them in the correct order. NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select. Answer : Explanation/Reference: To create a query that assigns vendors to items in Business Central, use the following code blocks in sequence: dataitem(Vendor; Vendor)

11. dataitem(Item; Item) DataItemLink = "Vendor No." = Item.Vendor_No; Creating a query:In Business Central, a query object is used to combine data from multiple tables. You start by specifying each table as a data item. In this case, you would start with the Vendor table and then the Item table. After specifying the data items, you need to link them together. The DataItemLink property is used to establish a relationship between two data items based on a common field. Here, you are linking the Vendor and Item tables on the "Vendor No." field, which is present in both tables. This link ensures that the query will return a dataset that includes related records from both tables based on the vendor number. The order of the code blocks ensures the logical flow and relationships between tables as required for the query.

You need to hide the field "Unit Price" from the Resource Card page. Which code snippet should you use? Option A : Option B : Option C : Option D :

12. Correct Answer: D Explanation/Reference: To hide the field "Unit Price" from the Resource Card page in Microsoft Dynamics 365 Business Central, you need to modify the visibility property of the field using the modify keyword, which allows you to change the properties of an existing field on a page. modify("Unit Price") is the correct way to target an existing field on a page (like the Resource Card page). The line Visible = false; makes the field invisible on the page. Here's a breakdown of why each option is right or wrong: Option A: Uses addlast("Unit Price"), which is incorrect because you are not adding a new field; you're modifying an existing one. Also, Visible = false is correct for hiding a field, but the wrong method (addlast) is used. Option B: Uses modify("Unit Price") with Enabled = false;. This would disable the field (make it noneditable), not hide it. The field would still be visible, so this does not meet the requirement. Option C: Uses addlast("Unit Price"), which is incorrect, and Enabled = false;, which would disable the field, not hide it. Option D: modify("Unit Price") { Visible = false; } is the correct syntax for hiding the field on the page. Correct Code Snippet: modify("Unit Price") { Visible = false;

13. } This hides the "Unit Price" field from the Resource Card page Download All Questions: https://www.microsoftdumps.us/MB-820-exam-questions QUESTION: 5 Topic 3 Misc. Questions A company has the following custom permission set: You need to make the permission set visible on the Permission Sets page. Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order. NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select. Answer :

14. Explanation/Reference: To make the permission set visible on the Permission Sets page, perform the following actions in sequence: Change the Assignable property value to true. Add the ObsoleteState = No property. Publish the app with the permission set to an environment. Process for making permission sets visible:In Business Central, the Assignable property determines whether a permission set is shown in the user interface for assigning to users. By default, if Assignable is set to false, the permission set is hidden. Therefore, it should be set to true to make the permission set visible. The ObsoleteState property indicates whether an object is outdated (Obsolete) or not (No). If an object is marked as obsolete, it is typically hidden from the user interface. Therefore, setting ObsoleteState = No ensures that the permission set is not treated as outdated and remains visible. Finally, publishing the app with the permission set to an environment updates the environment with the new or modified objects, including permission sets, making them available for assignment to users.

A user observes that some job queues go into the failed state and require manual intervention. You need to analyze job queue lifecycle telemetry. How should you complete the code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

18. Answer : Explanation/Reference:

19. KQL Code Segment: First command (traces): The query begins with traces to analyze telemetry data logs. The next command determines how the results are filtered or displayed. take 100: This is the correct option to retrieve the top 100 rows from the traces table. Command for selecting fields: project: This command is used to select specific fields from the telemetry data, allowing you to retrieve and display only the fields relevant to the job queue telemetry. The correct answer is project, as it allows you to choose fields like jobQueueObjectId, jobQueueObjectType, etc., from the customDimensions table. Download All Questions: https://www.microsoftdumps.us/MB-820-exam-questions QUESTION: 8 Topic 3 Misc. Questions You create a table with fields. You observe errors in the code You need to resolve the errors. For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

20. Answer : Explanation/Reference: In line 12, declare "Job Task" as a variable. = NO Add the property FieldClass = FlowField; for field 3. = YES Add the property FieldClass = FlowFilter; for field 3. = NO In line 23, assign the "User Setup" table to a field. = YES For "In line 12, declare 'Job Task' as a variable": In the AL code provided, the "Job Task" appears to be part of a CalcFormula of a FlowField, which means it references a table and not a variable. The "Job Task" does not need to be declared as a variable because it is used to reference a table in a CalcFormula expression. For "Add the property FieldClass = FlowField; for field 3": The line of code CalcFormula = sum("Job Task "."Recognized Sales Amount" where("Job No." = field("No."))); indicates that this field is calculated from other table data, which is the definition of a FlowField. Therefore, adding the property FieldClass = FlowField; is necessary for the field to function correctly. For "Add the property FieldClass = FlowFilter; for field 3": FlowFilters are used to filter data based on the value in a flow field. Since field 3 is using a CalcFormula to sum values, it is a FlowField and not a FlowFilter. Therefore, this statement is not correct.

21. For "In line 23, assign the 'User Setup' table to a field": The line TableRelation = "User Setup"; suggests that the "Project Manager" field has a relation to the "User Setup" table, which is a method of assigning a table to a field to ensure that the values in "Project Manager" correspond to values in the "User Setup" table. Hence, this statement is true. Download All Questions: https://www.microsoftdumps.us/MB-820-exam-questions QUESTION: 9 Topic 3 Misc.

Questions You develop a test application. You must meet the following requirements: •Roll back changes to a test method after run time. •Run an approve action on a test page named TestPageA. You need to implement the given requirements on the test codeunit Which actions should you perform? To answer, select the appropriate options in the answer area NOTE: Each correct selection is worth one point.

22. Answer : Explanation/Reference: To roll back changes to a test method after run time, you should: Set the TransactionModel attribute to AutoRollback. To run an approve action on a test page named TestPageA, you should: Configure TestPageA.Approve.Invoke(). In Business Central's testing framework, the TransactionModel attribute can be set to AutoRollback. This ensures that any changes made during the test are rolled back after the test is complete, leaving the database in its original state. For running an action on a test page, you would use the 'Invoke' method on the action you wish to perform. In this case, to run an approve action on TestPageA, you would use TestPageA.Approve.Invoke() within your test codeunit. This simulates the user action of approving something on the page. These actions ensure that the testing environment is properly set up to test specific functionalities without persisting test data and to invoke actions as part of the test scenarios.

24. MIXED Questions QUESTION: 12 You are developing an extension for Dynamics 365 Business Central that manages complex inventory adjustments. To gain insights into the usage and performance of this extension, you want to track how frequently specific adjustment types are used. Which method would you use to create a custom telemetry signal for this purpose? Option A : Extend the existing Inventory Adjustment table with new fields for tracking usage statistics. Option B : Create a custom AL function that logs usage data to a text file. Option C : Develop a custom event in the AL language that triggers when specific adjustment types are used. Option D : Leverage the built-in performance counters in Dynamics 365 for inventory adjustments. Correct Answer: C Explanation/Reference: C. Develop a custom event in the AL language that triggers when specific adjustment types are used. Here's why: Targeted data capture: You can define the event to specifically trigger when an adjustment of a particular type occurs. This provides precise data on usage of each adjustment type, eliminating the need to analyze or filter general adjustment data. Structured data: Custom events allow you to include relevant details within the event payload, such as adjustment type, date, user, item involved, and additional information depending on your needs. This structured data format facilitates efficient analysis and visualization within Application Insights. Integration with Application Insights: Sending custom events directly to Application Insights enables powerful features for visualizing usage trends, comparing activity across adjustment types, and identifying any deviations from expected patterns. While the other options offer some functionalities:

25. A. Extending the Inventory Adjustment table: While allowing data storage within Business Central, this approach requires manual analysis and might not be readily accessible for visualization within Application Insights. B. Custom AL function logging to a text file: Can be efficient for quick data capture, but requires additional processing and parsing of text logs for analysis, making it less organized and less convenient than Application Insights integration. D. Built-in performance counters: Primarily capture server-level metrics like resource utilization, not specific information about adjustment type usage within your extension.

However, users report receiving confusing error messages when invalid data is entered. How can you improve the user experience when encountering validation errors? (Choose one) Option A : Display generic error messages like "Invalid data entered." Option B : Highlight the specific field with an error indicator and provide a tooltip explaining the required format. Option C : Open a separate error page listing all invalid fields and requiring users to navigate back to correct them. Option D : Automatically correct the user's input to the closest valid value without their confirmation. Correct Answer: B Explanation/Reference: B. Highlight the specific field with an error indicator and provide a tooltip explaining the required format. Here's why this approach is superior: Clear Guidance: Directly highlighting the problematic field visually draws the user's attention to the source of the error, making it immediately clear where correction is needed. Contextual Explanation: Providing a tooltip with specific information about the required format or accepted values offers immediate guidance without interrupting the user's workflow. This helps users understand the error and make necessary adjustments without frustration. Streamlined Correction: Users can rectify the issue within the same context, avoiding unnecessary navigation or back-and-forth

26. actions, thus enhancing efficiency and reducing potential errors. Why the other options are less effective: A. Generic Error Messages: These provide limited information and might confuse users, especially those unfamiliar with technical terms or specific validation requirements. C. Separate Error Page: This disrupts the user flow, forcing users to navigate back and forth between pages to identify and correct errors, leading to potential frustration and wasted time. D. Automatic Correction: While potentially helpful in certain scenarios, it can lead to unexpected results if the correction isn't accurate or doesn't align with the user's intended input, potentially compromising data integrity and user trust.

They want to manage and test these extensions simultaneously but maintain their distinct functionalities. Which feature of Visual Studio Code best supports working with multiple AL extensions in one workspace? Option A : IntelliSense code completion for AL across all extensions Option B : Debugging breakpoints set across multiple extension files Option C : Local symbol servers for each individual extension Option D : Multi-root workspaces for organizing and switching between extensions Correct Answer: D Explanation/Reference: D. Multi-root workspaces for organizing and switching between extensions. Here's why multi-root workspaces are ideal for this scenario: Organization: Multiple extensions can be grouped within a single workspace, each with its own folder structure and settings. This keeps the development environment organized and manageable. Independent development: Extensions within a multi-root workspace can be edited, compiled, and tested independently, even if they have dependencies on each other. This allows for focused development and testing of individual extensions without

27. affecting others. Easy switching: You can quickly switch between extensions using the File Explorer or VS Code's navigation features, making it efficient to work on different parts of your project. Customizable settings: You can apply different settings, extensions, or tasks to each extension folder as needed, catering to specific requirements of each project. Why other options are less suitable: A.IntelliSense code completion: While helpful, it's not specific to multi-extension scenarios. It works within individual projects regardless of workspace structure. B.Debugging breakpoints: This feature is valuable for debugging, but it doesn't address the primary challenge of managing multiple extensions in a unified workspace. C.Local symbol servers: These operate within individual projects, not across multiple extensions in a workspace. They don't provide the same level of integration and organization as multi-root workspaces. Download All Questions: https://www.microsoftdumps.us/MB-820-exam-questions QUESTION: 15 You're working on a Dynamics 365 Business Central extension that includes a new page with sensitive data. You want to ensure only specific users can access this page, even if they have permission sets granting access through entitlements. How can you achieve this override and restrict access based on your specific requirements? (Choose one) Option A : Modify the existing entitlements directly within the extension code, removing access for specific users or groups. Option B : Assign a new permission set to the sensitive page that explicitly denies access to all users, overriding any entitlements. Option C : Implement custom code within the page to check user permissions and prevent access for unauthorized users based on your custom logic. Option D : Utilize the "Inherent Permissions" feature within Business Central to define specific user roles who can access the page, overriding any conflicting permissions from entitlements. Correct Answer: C

28. Explanation/Reference: C. Utilize Data Level Security filters to exclude the specific customer group from the user's view, overriding the inherent permission based on customer group criteria. Here's why: Targeted restriction: Data Level Security filters allow you to define precise access limitations based on specific fields and values, in this case, the customer group field. This avoids modifying the inherent permission, leaving it intact for other users in the "Sales Manager" role. Non-invasive approach: You don't need to alter user groups or create custom code, making it a simpler and more maintainable solution. Flexibility: This method can be easily applied to multiple user roles and scenarios by adjusting the filter criteria to match different data access restrictions. The other options have drawbacks: A. Modifying inherent permission: This impacts all users with the "Sales Manager" role, potentially causing undesired access changes for others. B. Separate permission set: This adds complexity by creating an additional permission set and managing user assignments, while still requiring filter implementation for targeted restriction. D. Custom code: This introduces unnecessary complexity and ongoing maintenance needs, especially when compared to the built-in functionality of Data Level Security filters.

Microsoft requires that all data, especially personal data, be classified using the data classification feature to comply with GDPR and other data privacy regulations. QUESTION: 17

30. A company developed a critical custom extension for Business Central but haven't updated it in several years. Their Business Central environment is due for a major upgrade soon. What is the most likely scenario regarding the extension's compatibility? Option A : The extension will automatically update and function seamlessly with the new version. Option B : The extension will likely require minor adjustments for compatibility issues. Option C : The extension might be completely incompatible and require redevelopment. Option D : Microsoft will automatically offer upgrade services for all custom extensions. Correct Answer: B Explanation/Reference: B. The extension will likely require minor adjustments for compatibility issues.

31. Here's why: Business Central releases: Microsoft regularly releases new versions of Business Central, introducing new features and functionality. While upgrades usually strive for backward compatibility, changes between major versions can still cause issues with older custom extensions. Lack of updates: Since the extension hasn't been updated in several years, it's highly likely that it will encounter some incompatibility with the new features or changes in the updated Business Central version. Potential issues: Depending on the extent of changes in the new version and the complexity of the extension, various compatibility issues might arise, like broken functionality, invalid references, or data errors. Minor adjustments: Fortunately, in most cases, compatibility issues with custom extensions can be resolved through minor adjustments to the extension's code. These adjustments might involve updating references, adapting to new APIs, or adjusting functionalities to comply with the new version's structure. However, while scenario B is the most probable, the other options also have some possibility: A. Automatic compatibility: Although unlikely, a chance exists that the extension was built using modern practices and utilizes standard APIs, making it automatically compatible with the new version without modifications. This is less likely for extensions developed several years ago. C. Complete incompatibility: While rare, if the extension relies heavily on outdated functionalities or features removed in the new version, complete incompatibility and redevelopment might be necessary. However, Microsoft usually focuses on maintaining backward compatibility for core features. D. Automatic upgrade services: Unfortunately, Microsoft doesn't provide automatic upgrade services for all custom extensions. The responsibility for ensuring compatibility lies with the developers or the company maintaining the extension. Download All Questions: https://www.microsoftdumps.us/MB-820-exam-questions QUESTION: 18 A company wants to track the total number of sales orders placed for each customer in the current month. Existing reports only show historical data. You need to develop a solution using AL to achieve this. Which of the following options is the BEST approach to implement this data manipulation in Business Central using AL? Option A : Create a new table to store monthly sales order data for each customer. Option B : Add a new field to the "Sales Order" table to store the current month for each order. Option C : Extend the "Sales Order" table with a calculated field that shows the total count of orders for the current month for each customer.

32. Option D : Use the "CRON Trigger" to run a job every day that calculates and stores the monthly sales order count for each customer. Correct Answer: C Explanation/Reference: c)Extend the "Sales Order" table with a calculated field that shows the total count of orders for the current month for each customer. Here's why: •Option a) creates redundant data and increases storage needs. It also adds complexity to your data maintenance. •Option b) doesn't provide the desired information directly. You would still need to filter by the current month, increasing code complexity and potentially impacting performance. •Option d) introduces unnecessary processing overhead by running a daily job even if no new orders are placed. It also adds complexity to your codebase. Using a calculated field: •Is efficient: No need for additional data storage or daily jobs. •Is straightforward: The information is readily available on the Sales Order table itself. •Is performant: Calculated fields generally have minimal impact on performance. Here's how you can implement this with AL: Code snippet 1.// Add a new calculated field to the Sales Order table 2.field(50000; "Monthly Order Count"; Integer; CalcFormula("'Sales Order' where "Customer No." = CustomerNo && "Posting Date" >= StartOfMonth(CurrentDate) && "Posting Date" <= EndOfMonth(CurrentDate).Count") 3. 4.// This field will automatically calculate the total number of sales orders for the current month for each customer. This approach balances simplicity, efficiency, and performance, making it the most suitable solution for your desired outcome.

33. QUESTION: 19 You're developing a custom API in Business Central that experiences performance bottlenecks during peak usage periods. This API fetches large datasets from external sources based on user requests. How can you leverage Read-Scale Out to improve the responsiveness of your API? Option A : Implement caching mechanisms within your API code to store frequently accessed data. Option B : Configure the Business Central server for Read-Scale Out with multiple secondary servers. Option C : Utilize server-side JavaScript (SSJS) for complex data manipulation within the API. Option D : Increase the memory allocation of the Business Central server. Correct Answer: B Explanation/Reference: B. Configure the Business Central server for Read-Scale Out with multiple secondary servers. Here's why: 1.Read-Scale Out benefits: This feature replicates the database onto secondary servers, allowing them to handle read-only workloads like your API's data retrieval from external sources. This distributes the load and significantly improves performance during peak times. 2.Efficiency and Cost-effectiveness: Read-Scale Out utilizes existing infrastructure effectively without requiring additional development effort like implementing caching or complex SSJS functions. It's also often more cost-effective than simply increasing server memory, which might not solve the fundamental bottleneck for large data reads. While other options have value, they're not the best choices for addressing this specific scenario: A. Caching: While effective for frequently accessed data within Business Central itself, it won't address the bottlenecks associated with fetching large datasets from external sources. C. SSJS: Primarily used for UI customization and scripting within Business Central, it's not designed for large-scale data manipulation and might further contribute to performance issues. D. Increasing Server Memory: This could provide temporary relief, but it's not a scalable solution, especially for handling large external data sets efficiently.

34. QUESTION: 20 A company wants to automatically calculate the "Delivery Cost" for a sales order based on the order weight and destination country. However, during calculation, an external API call might fail due to internet connectivity issues. You need to manage this potential error. Which of the following options is the BEST way to handle the API call failure in this scenario using AL? Option A : Retry the API call several times before giving up. Option B : Display a generic error message and skip calculating the "Delivery Cost". Option C : Log the error and use a fallback value for the "Delivery Cost" based on predefined country groups. Option D : Inform the user about the error and allow them to choose whether to try again or continue without the cost calculation. Correct Answer: C Explanation/Reference: c) Log the error and use a fallback value for the "Delivery Cost" based on predefined country groups. Here's why this option is superior: Improved User Experience: Skipping the cost calculation or displaying a generic error message wouldn't provide helpful information to the user. Using a fallback value ensures at least an estimated cost can be presented, minimizing disruption to the sales order process. Resilience and Error Logging: Logging the error helps diagnose any connectivity or API issues, allowing for corrective actions or future improvements. Controlled Fallback: Utilizing predefined country groups for fallback values provides a more informed estimation than a random or default value. This could involve grouping countries with similar shipping profiles or referencing historical average costs. While other options might work in certain situations, they have drawbacks: Option a): Retrying the API call might further delay the process and consume extra resources if the issue persists. Option b): Skipping the cost calculation would leave the user uninformed and could cause confusion or incomplete order information.

35. Option d): While user choice offers flexibility, it might be unnecessary for a single API call failure and could potentially delay or complicate the sales order process.

You need to develop a solution using AL to automate this process. Which of the following options is the MOST efficient and reliable way to achieve this data manipulation in Business Central using AL? Option A : Use the "Excel Interop" functionality to directly read and update the "Item Price" field on sales lines. Option B : Import the Excel data into a temporary table and then write a loop to update the "Item Price" field on each sales line based on the matching item number. Option C : Use the "Data Exchange Framework" to import the Excel data and map it to the "Sales Line" table, automatically updating the "Item Price" field based on the item number. Option D : Use the "CRON Trigger" to run a job every hour that checks for new Excel files and updates the "Item Price" field on sales lines accordingly. Correct Answer: C Explanation/Reference: c) Use the "Data Exchange Framework" to import the Excel data and map it to the "Sales Line" table, automatically updating the "Item Price" field based on the item number. Here's why: Option a) is highly unreliable and error-prone because Excel Interop can be sensitive to Excel versions and formats. It's also considered deprecated in newer versions of Business Central. Option b) is less efficient because it requires an additional temporary table and looping through each sales line. There's also a higher risk of data inconsistencies while manually mapping the data. Option d) introduces unnecessary overhead by running a frequent job even if there are no new price updates. It also adds complexity and might impact performance. Using the Data Exchange Framework:

36. Is designed for data import and mapping: It provides a robust and well-maintained framework for handling data exchanges with external sources like Excel files. Is efficient: It uses optimized import routines and avoids unnecessary looping. Is reliable: It handles data validation and mapping errors gracefully, ensuring data integrity. Is flexible: You can easily adapt the import configuration to different Excel file formats and structures. QUESTION: 22 You have two permission sets in Dynamics 365 Business Central: "Sales Rep" and "Sales Manager." Both grant access to the "Customer" table. The "Sales Rep" permission set includes an entitlement to view all customers, while the "Sales Manager" has an inherent permission to see all customer data. What happens when a user belongs to both permission sets? (Choose one) Option A : The user can only see customers assigned to them based on the "Sales Rep" entitlement. Option B : The inherent permission from "Sales Manager" overrides the entitlement, granting the user access to all customers. Option C : The user has conflicting permissions and Business Central throws an error. Option D : Both entitlements work simultaneously, allowing the user to see all customers and perform actions based on both permission sets. Correct Answer: B Explanation/Reference: B. The inherent permission from "Sales Manager" overrides the entitlement, granting the user access to all customers. Here's why: Entitlements and inherent permissions: In Dynamics 365 Business Central, entitlements define user access to specific features and data based on the functionality of the license or extension. Inherent permissions, on the other hand, are hardcoded privileges associated with certain roles or positions, often granting more extensive access. Overriding effect: When a user belongs to multiple permission sets with overlapping permissions, the stronger privilege takes precedence. In this case, the inherent "See All Customer Data" permission granted by the "Sales Manager" role inherently overrides the "View All Customers" entitlement from the "Sales Rep" permission set.

37. Conflict resolution: Business Central doesn't throw an error in this scenario. Instead, it resolves the conflict by granting the user the highest level of access available from their combined permissions.

They want to examine the values of variables and expressions within the current context to understand the code's behavior. Which debugging tool in Visual Studio Code should they use to view these values? Option A : The Call Stack panel Option B : The Variables panel Option C : The Output panel Option D : The Watch panel Correct Answer: B Explanation/Reference: B. The Variables panel. Here's a breakdown of the key debugging panels and their purposes: Variables Panel: Primary purpose: Displays the values of variables in the current scope, including local variables, function parameters, and global variables. Inspection: You can expand objects and arrays to view their nested properties and elements. Value updates: The panel dynamically updates as you step through the code, reflecting changes in variable values. Other Panels and Their Uses: Call Stack panel: Shows the sequence of function calls that led to the current breakpoint, aiding in tracing the execution path. Output panel: Displays general output from the debugger, such as messages, errors, and logging statements.

38. Watch panel: Allows you to add specific variables or expressions to monitor their values throughout the debugging session, even if they go out of scope. QUESTION: 24 You are tasked with creating a custom page in Business Central to display customer orders placed within the last week. Which of the following statements accurately describes the basic structure of AL code used to achieve this functionality? Option A : AL code is primarily composed of functions and procedures, with variables declared within each function. Option B : AL code is written in a declarative style, using properties and events to define page elements and their interactions. Option C : AL code uses a combination of imperative and declarative approaches, with functions for logic and events for user interaction. Option D : AL code is primarily event-driven, with functions triggered by specific user actions or system events. Correct Answer: C Explanation/Reference: c) AL code uses a combination of imperative and declarative approaches, with functions for logic and events for user interaction. Here's why: Imperative and Declarative: AL code combines both approaches. Imperative: You use functions and procedures to define logic and calculations, similar to traditional programming languages. Declarative: You use properties and events to define page elements and their interactions with the user interface and data. Functions for Logic: You write functions to handle data manipulation, calculations, and other processing tasks needed for your custom page. Events for Interaction: You utilize events to define how page elements react to user actions or system triggers. This includes events like "OnOpen" for page initialization, "OnInsert" for adding new data, and "OnValidate" for user input validation.

39. Therefore, an AL code page would typically: Define page elements: Use properties to specify layout, fields, and data sources for the page. Implement logic: Write functions to filter data, calculate values, or interact with external systems based on your custom requirements. Handle events: Bind event handlers to page elements or system events to respond to user actions or data changes. By combining the imperative power of functions with the declarative structure of events and properties, AL allows you to efficiently build custom pages with dynamic behavior and user interaction in Business Central.

You are tasked with developing an extension that automates routing Purchase Orders for approval based on the order amount and vendor. The extension should integrate seamlessly with the existing document approval workflow in Business Central. Which of the following options best leverages document standards to achieve automated Purchase Order routing for approval? Option A : Create a custom workflow with triggers and conditions based on order amount and vendor. Option B : Utilize the "Document Approval Workflow" feature and configure dynamic routes based on custom fields. Option C : Develop a custom user interface for selecting approvers based on order details. Option D : Modify the existing "Purchase Order" table to store routing information directly. Correct Answer: B Explanation/Reference: B. Utilize the "Document Approval Workflow" feature and configure dynamic routes based on custom fields. Here's why: Leveraging existing functionality: Business Central already comes with the "Document Approval Workflow" feature specifically designed for automating document routing based on defined rules. Utilizing this built-in feature aligns with document standards and minimizes custom development efforts.

40. Dynamic routing based on custom fields: This option allows you to create custom fields on the "Purchase Order" table to capture vendor and order amount. Then, you can configure dynamic routing rules within the "Document Approval Workflow" based on these custom field values. This ensures flexible and scalable routing based on your specific approval process requirements. Seamless integration: Using the existing workflow feature guarantees seamless integration with the existing document approval system in Business Central. This avoids potential compatibility issues and maintains a consistent user experience within the platform. Limitations of other options: A. Custom workflow: While feasible, it involves significant custom development, potentially leading to increased maintenance overhead and potential integration challenges. C. Custom user interface: This approach creates a separate UI element outside the natural document flow, disrupting the user experience and adding complexity. D. Modified "Purchase Order" table: Directly storing routing information in the table deviates from standard document management practices and can lead to data management challenges in the future. QUESTION: 26 The developer has completed their multilanguage extension and deployed it to a non-production environment. Users report that some translated strings appear truncated or misformatted when displayed in the user interface. How can the developer diagnose and fix these translation issues effectively? Option A : Use the Business Central debugger to step through the code and analyze the translation function calls. Option B : Enable detailed tracing for the extension and review the generated trace logs for translation errors. Option C : Analyze the translated resource files directly for formatting inconsistencies or invalid characters. Option D : Contact Microsoft support for assistance with troubleshooting multilanguage functionality in extensions. Correct Answer: C

41. Explanation/Reference: C. Analyze the translated resource files directly for formatting inconsistencies or invalid characters. Here's why this approach is best suited for this type of problem and why the other options aren't as effective: Focus on Resource Files: Root cause: The issue is likely within the translated text itself, not the translation process or code. Direct inspection: Analyzing the resource files allows for careful examination of the text and formatting for potential errors. Common causes: Formatting inconsistencies (e.g., extra spaces, line breaks), invalid characters, or encoding issues are common culprits for display problems. Why Other Options Aren't Ideal: A. Debugger: While helpful for debugging code logic, it's not as effective for troubleshooting translation issues within resource files. B. Tracing: Tracing can provide insights into code execution, but it's less useful for examining the content of translated text itself. D. Microsoft support: While valuable for assistance, contacting support should typically be a later step after exhausting self- troubleshooting options.

You want to isolate the unit test from the actual API to ensure it tests the core logic of your function. Which of the following techniques is the most appropriate for mocking the external API in your unit tests? Option A : Use the "TestPage" concept to mock the API behavior within Business Central. Option B : Write a separate AL codeunit to simulate the API responses. Option C : Leverage the built-in "TestMocks" framework provided by the ALTest framework. Option D : Use the "Record Replay" functionality to capture responses from the real API and replay them in the test. Correct Answer: C Explanation/Reference: C. Leverage the built-in "TestMocks" framework provided by the ALTest framework. Explanation: A. TestPages are primarily for UI testing, not mocking external dependencies. B. Writing a separate codeunit adds complexity and maintenance overhead. D. Record Replay can be brittle and doesn't provide fine-grained control over the mocked responses. C. TestMocks is a dedicated framework for mocking external dependencies in AL tests. It allows you to define mock objects with specific behavior and responses, providing greater control and flexibility for testing your code in isolation. QUESTION: 28

44. You're creating an AL extension in Dynamics 365 Business Central to automate processing customer orders received as XML files. The extension needs to import the order data, create corresponding sales orders in Business Central, and send an acknowledgement message back to the sender. How would you utilize XMLports within the AL code to achieve this functionality? (Choose two) Option A : Use the XMLPort.CreateInstance function to load the relevant XMLport for importing customer orders. Option B : Implement custom parsing logic within the AL code to directly read and interpret the XML data without using XMLports. Option C : Call the XMLPort.Run function with the imported XML data and target XMLport for order creation. Option D : Trigger the existing "Customer Order Import" XMLport through events or code actions within your extension. Option E : Send the acknowledgement message using the SMTPMail function in AL, including relevant order details. Correct Answer: A,C Explanation/Reference: A. Use XMLPort.CreateInstance function: This function initializes a new instance of the XMLport object, enabling you to interact with it programmatically. You'd provide the name of the specific XMLport designed for importing customer orders ("Customer Order Import" in this case). C. Call XMLPort.Run function: Once you've created an instance of the XMLport, you'd call the XMLPort.Run function to initiate the import process. This function accepts two parameters: The XML data from the received file, which you'd likely load using FileMgt.GetTextFile or similar file handling functions in AL. The target XMLport object (the instance created using XMLPort.CreateInstance). The other options aren't directly related to XMLport usage:

45. B. Implementing custom parsing logic: This involves manually reading and interpreting the XML data without using XMLports, which can be more complex and less efficient, especially for structured data exchange. XMLports are specifically designed to handle such tasks. D. Triggering the XMLport through events or code actions: While indirectly related, this option highlights alternative ways to initiate XMLport execution, such as setting up event subscriptions or calling the XMLport from other actions within your extension. E. Sending acknowledgement message: This involves email functionality using SMTPMail in AL, but it's not directly related to XMLport usage. It's a separate step in your extension's process. QUESTION: 30 A manufacturing company wants to automatically assign serial numbers to newly created production orders based on a specific format: •The format starts with the product code. •It includes a sequential number starting from 1 for each product code. •It's padded with leading zeros to reach a total length of 10 characters. You need to develop an AL function to achieve this serial number generation. Which of the following AL expressions BEST represents the logic for creating the serial numbers? Option A : Code snippet 'PR-' + Item.Code + STRZERO(ProductionOrder.COUNT(ProdOrder where Item.Code = CurrentProdOrder.ItemCode) + 1, 5) Option B : Code snippet 'PR-' + Item.Code + FORMAT(ProductionOrder.COUNT(ProdOrder where Item.Code = CurrentProdOrder.ItemCode) + 1, '00000') Option C : Code snippet ProductionOrder.SerialNo := 'PR-' + Item.Code + REPLICATE('0', 10 - (STRLEN(Item.Code) + STRLEN(ProductionOrder.COUNT(ProdOrder where Item.Code = CurrentProdOrder.ItemCode) + 1))) Option D : Code snippet serialNo := 'PR-' + Item.Code + FORMAT(ProductionOrder.NEXT(SerialNo), '00000'); ProductionOrder.SerialNo := serialNo; Correct Answer: B

46. Explanation/Reference: b) 'PR-' + Item.Code + FORMAT(ProductionOrder.COUNT(ProdOrder where Item.Code = CurrentProdOrder.ItemCode) + 1, '00000') Here's why this expression is optimal: Correct Formatting: It concatenates the required elements: "PR-", the product code, and the sequential number. It uses the FORMAT function to apply leading zeros to the sequential number, ensuring a consistent 10-character length. Accurate Sequencing: It counts the existing production orders with the same product code using a filtered COUNT method. It increments the count by 1 to assign the next available serial number. Efficiency: It leverages built-in functions like FORMAT and COUNT for efficient string manipulation and counting. Clarity: The expression is concise and easy to understand, making code maintenance simpler. While other options might generate serial numbers, they have drawbacks: Option a): STRZERO might not be an available function in AL, and its behavior isn't guaranteed. Option c): REPLICATE can be less efficient for fixed-length padding compared to FORMAT. Option d): ProductionOrder.NEXT(SerialNo) might not exist in AL, and its logic is unclear. QUESTION: 31 The Sales Team Role Center page you created has a filter on the "Top Customers by Revenue" section that dynamically updates the list and the embedded chart. However, users report that the chart sometimes takes longer to update than the list. How can you improve the performance of the chart loading on this page? Option A : Increase the refresh rate of the Role Center parts. Option B : Use the OnAfterGetRecord trigger in the List part to pre-calculate data for the chart.

47. Option C : Set the chart to display only static data filtered by the user. Option D : Move the chart to a separate Role Center page. Correct Answer: B Explanation/Reference: B. Use the OnAfterGetRecord trigger in the List part to pre-calculate data for the chart. Here's how this approach works: Trigger: The OnAfterGetRecord trigger in the List part fires each time a record is retrieved for the list. Pre-calculation: Within this trigger, you can add code to perform the necessary calculations for the chart data based on the filtered list. Chart Data Source: The pre-calculated data is then stored in a temporary table or variable. Chart Binding: The chart's Data Source property is set to this temporary table or variable, ensuring it displays the pre- calculated data. This approach offers several advantages: Reduced Processing Delay: The chart data is ready for display as soon as the list updates, eliminating the lag caused by re- calculating data on the fly. Optimized Performance: Pre-calculating data in the List part's trigger is generally more efficient than re-calculating it each time the chart refreshes. Seamless User Experience: Users perceive a smoother and faster update of the chart, enhancing their interaction with the Role Center page. The other options have potential drawbacks: A. Increasing refresh rate: Might lead to unnecessary server load and a less responsive user experience. C. Displaying static data only: Limits the dynamic nature of the chart and might not meet the users' needs for real-time insights. D. Moving the chart to a separate page: Creates additional navigation steps and might disrupt the user flow. Download All Questions: https://www.microsoftdumps.us/MB-820-exam-questions
