2. Select a corporation from the dropdown list and click `Go`

3. Select a country from the dropdown list and click `Go`

4. Enhance your queries filling out other fields. From this point you can select other fields to enhance your criteria but they are optional fields. Once you are done, make sure that Ready to search is checked then click GO to search. • Country option: this field allows you to see invoices where P.T.C or T.C are equal to the country you selected above. In this example, if you select „By Tax Country (T.C.)“, the system will search for all invoices where T.C. Is Finland. • Buying Company: select one from the list. It is possible that you find duplicated names for Buying Company but internally they are separate companies (they have unique IDs). • Supplier numbers: you can type in supplier numbers on this field. If you do not remember the number, you can click the magnifying glass on right and do a search by name <details on next slide>

5. Searching suppliers by name By clicking the magnifying glass icon you will get a popup window from where you can search suppliers by name. Type something, include the special character % to act as wild card and click Go. Here we put 2 % chars because the name we want is somewhere in the supplier name. If there are suppliers for the country you selected with the text you typed in, then you‘ll get the screen shown on right. See details on next slide

6. Manipulating the suppliers rows found Once you get the results of your search on the popup window, you can select the suppliers by clicking the chek mark buttons on the left, one by one manually. Or you can also use the special labels above: All – This function will check mark all rows from the result set automatically for you, as shown on right. None – This function releases (uncheck) all items at once. More details on the next slide

7. Including, excluding with feature `Switch` Switch – This function usefull when you get a result set but wants to exclude some items. Looking at the example, suppose you‘ve got 9 rows but want to exclude items 1, 3 and 4. The easiest way is to mark them and click on Switch. All be selected except items 1, 3 and 4 you checked. If you click Switch again, you revert the process as shown. Use Selected – This function will close the popup window and paste the items you checked (if any). More details on the next slide

8. Finalizing and pasting items selected Use Selected – As said previously you check the items you want to select and click use `selected` as shown to paste the supplier numbers. Also notice that this is a cumulative process which means you can repeat the process to add more supplier numbers. When you have all the supplier numbers listed, you can check `Ready to search` and click `Go` More details on the next slide

9. Results found for that Corporation, Country and Suppliers As expected you get a list of available invoices for the Corporation, Country and Supplier numbers you selected previously. From here you can click `Back` and start over or click the magnifying glass on left to see the invoice details. See next slide for more information.

10. More fields to fine tune your queries Date: You can also search based on dates. In this case you need to define what date are you refering to: • By Invoice Create Date: this is the date this invoice was created. • By Digitally Signed Date : Here the system will search for `Digitally Signed` invoices only, specifically on this date. • When queries are defined, check the `Ready to search` field and click `Go`

11. Learning the details When you search for invoices you get results of digitally signed and stored only invoices. `Stored only` is the term to identify the invoices not signed. What is in the file is its image in XML format. You can even visualize them on your browser. On the other hand Digitally Signed invoices are encripted data suitable to be validated by a service named Trust Weaver.

12. Stored only versus Digitally Signed invoices Let‘s start with a `Stored Only` invoice. Clickin the magnifying glass as shown will bring another page with the invoice details. See next slide.

13. Downloading a `Stored` invoice By clicking on any invoice from the list this screen will be presented. Look for a file with extension xml down below the page in your browser. Here you can follow the instructions on screen to save the attached file to you local machine in order to validade it later with Trust Weaver service.

14. Saving to a local directory Following the instructions on the details page, you should save the file to a local directory or folder. Please notice that the system always generates a new unique file name when you click on an invoice link to see its details. The file name convention is based on internal user id plus the current date and time at the application server. So it is normal to get a different file name each time you come to this details page.

15. `Stored` invoices details can be visualized in this tool If you are dealing with a `Stored Only` invoice, you can see the file contents by clicking on the attachment, as shown here. This is a plain XML formatted file. This type of file is not suitable for Trust Weaver services. If you try it you will get an error, as we will see later.

16. Working with Digitally Signed invoices Now let us see the details for a Digitally Signed invoice. Click and save the xml file to a local folder.

17. Same process to download and save to a local folder Right click the attached file and save it to a local folder as shown before

18. Choose a folder and save. Better to keep `Stored` and `Signed` invoices in separate folders Right click the attached file and save it to a local folder as shown before

19. The tool cannot visualize `Digitally Signed` invoices. Unlike the `Store Only` invoice, if you try to open this file you will get an error. This is correct because this file is digitally signed and was encripted in the process so your browser cannot understand it. The picture below shows how a digitally signed file looks like

20. We have Trust Weaver services for `Digitally Signed` ones Now that you know how to search for an invoice, see its details and download the attached XML file to our local machine, you can take a look at how to validate an invoice or group of invoices with Trust Weaver web site. This must be done manually since it is an external public service and cannot be automatically accessed from our application. Following the detail intructions page, you should open another browser instance and go to https://tsod.trustweaver.com/test/tseiod/Validate.aspxLet‘s do it now.

21. Browsing a local folder to select and validate a file Still according to our detail instructions page, you should follow the instructions from Trust Weaver web site to validate your invoices. Remember that only Digitally Signed invoices are accepted. Let us practice a bit and confirm if it can validate a `Store Only` invoice. We saved before a file named 01000011VP2008131424390.xml and we know it is not a signed one. But we want to check it. So we will upload it to Trust Weaver service. On the Trust Weaver page, click `Browse` and choose that file.

22. `Store only` invoices are invalid for Trust Weaver services After you pick the file, click `Validate` on Trust Weaver page to send the file for validation. As shown below, it did not recognise the file format sent. So remember: only Signed invoices can be validated.

23. `Digitally signed` are always welcome there Now let us upload another invoice file this time a signed one we saved before. Click `Validate` and as expected it is recognised as a valid file.

24. Easy your validation process by packaging invoices You search for invoices, open their details and save them locally. Then you can go to Trust Weaver and validate them one at a time. Or you can create a compacted (zip) file with all the invoices you want validate and submit it. For this purpose let us pick some files saved previously and create a compressed file. Go to Windows Explorer and access your local directory where the files are. Highlight them and right click in one of them and choose `Send To | Compressed (zipped) Folder.

25. Zip format is accepted all over As said this creates a ZIP file with all the invoices you highlighted. The file name will be the same as the file you right clicked over as shown here. Let us upload this zip file to Trust Weaver to test the `Validate by Group` service.

26. Trust Weaver works fine with zipped invoices We browse and choose our zip file, then we submit for validation. And below you can see the file names we compressed. Now you can click on `View details` to know more about one invoice.

27. They offer other services for `digitally signed` invoices When you click `View details` you can learn more about that particular invoice as shown on the next slide.

28. There are many other services available once you click on `View details`. One that is really nice is the one as `Show e-invoice content in human-readable form`. It allows to visualize and print any invoice. Check them out. Some extra services available

29. Visualizing a `Digitally Signed` invoice. You can even print it Detail showing invoice in human-readable format.
