  5. Add-Ins: Definition • No change licences necessary • Interfaces are upwardly compatible • Less work at upgrade Add-ins are points in an object’s source code where additional functions or statements can be inserted. Add-ins are defined by the object’s initial developer and allow other developers to easily include additional code in a subsequent phase of development without having to ‘modify’ the original.Additional advantages:

  6. Business Add-Ins • Delivery of implemented add-ins (country-specific versions, IBU solutions, partner software, ...) • Technique can be used by other software vendors • Delivery and correction of default solutions (4.6C) • Filter-dependent implementation possible • ‘Event-like’ add-ins (Publish & Subscribe) • Integrated administration and documentation • Trace possibilities

  7. Why Business Add-Ins? • Perform calls in programs / using tables • Flexible <-> Fuzzy interface (global data,...) • Customer exits (SMOD/CMOD) • System infrastructure: SAP - customer • Naming convention not compatible with namespace extension • Business Transaction Events (Open FI) • No bundle of objects that belong together • No interface elements Business Add-Ins should be viewed as expanded and enhanced business transaction events

  8. IF_app_exit Generate class mth1 mth2 mth3 ... Architecture Application Customer Program XXX. Data: exit type ref to if_app_exit. Create object... Call method... CL_imp_app_exit mth1 mth2 mth3 ...

  9. Example Program REPORT BADI . DATA EXIT TYPE REF TO IF_EX_BADI. DATA WORD(15) TYPE C. CALL METHOD CL_EXITHANDLER=>GET_INSTANCE CHANGING INSTANCE = EXIT. START-OF-SELECTION. WRITE:/ 'Please click here'. AT LINE-SELECTION. NEW-PAGE. WORD = 'Business add in'. WRITE:/ 'Original word: ', WORD. CALL METHOD EXIT->METHODE CHANGING PARAMETER = WORT. WRITE:/ 'Changed word: ', WORD.

  10. Filter Dependence • Type of filter: data element with search help • Parameter flt_val must be suitably filled when the add-in is called. • Add-in must be implemented for a specific filter value. Sometimes it is important for partners to be able to implement and deliver a single add-in with different filter values (for different countries, for example). For this reason, add-ins can be defined for specific filter values.

  11. Add-in implementation Add-in definition IF_app_exit Type of filter dependency: country-specific IF_app_exit Country:Japan Exit call Country:China ... Exit type ref to IF_app_exit. Country = ‚J‘. Call method exit->mth1 exporting flt_val = country. ... Filter-Dependent Add-Ins

  12. Business Add-In Manager • Definition part (SE18) • Specification of common Interface (method collection) • Define Add-In Type (publish & subscribe, filter dependent) • Automatic generation of adapter classes • Implementation (SE19) • Select filter value (e.g. country code) • Supply code for interface methods • Activate Add-In
