SES 35: Business Add-Ins in SAP ABAP

August 3, 2019
Dixita Galiyal

Since SAP NetWeaver 7.0, the Business Add-Ins (BADIs) are used for enhancements in SAP, as they provide modern enhancement technology.

Features of BADIs

  • The new and currently used BADIs are incorporated in enhancement framework with enhancement sections and points.
  • BADIs give better improved performance and functions like filter and the option to inherit properties from a class.

The BADIs are managed by enhancement spots, unlike classic BADIs. In a classic BADI, both BADI definition and interface are built using transaction code SE18, which generates BADI adapter class.

Call Syntax of Classic BADI Program Exit

In any SAP program, a reference variable is defined using BADI interface type. When the class CL_EXITHANDLER is called, BADI instance is built. Thus, the bridging method is called via BADI instance for implementation.

Steps to search for a Classic BADI Program Exit

  • Use SE84 to do BADI free search.
  • Use code SE81 followed by SE84, to list out BADIs for a particular application.
  • For a program search, look for GET_INSTANCE globally and to go to BADI interface, click the reference variable returned from GET_INSTANCE method.
  • Put up a where used search to find out where the interface is used in classes and finally, read BADI implementation using SE18.

#Insight

As an alternate option, you can set a breakpoint for the method GET_INSTANCE in the debugger and then search for uses of reference variables in the program.

Steps to implement Class BADI Program Exit

  • Use SE18 to show BADI definition. Then, select CREATE IMPLEMENTATION where you’ll find SE19.
  • Select and write a name for BADI implementation.
  • For implementation, click on method names of interface tab.
  • Finally, activate all the methods, implementation class and BADI implementation.

#Personal Recommendation

One of our personal favorites, the COMPLETE SAP ABAP is the best fit when it comes to learning and concept building, understanding of codes and error correction.
