Mastering SAP ABAP

Handling

Unlike classic exceptions, class-based exceptions are not a part of the method call. This is partly due to the separation between CX_STATIC_CHECK, CX_DYNAMIC_CHECK, and CX_NO_CHECK—not all of them are required to be handled every time. Similar to other object-oriented languages with the exception mechanism, class-based exceptions are caught with the TRY-CATCH block. In ABAP, however, the aforementioned block is further enhanced with several optional context-control statements, shown in the following code snippet:

TRY.    ...execute standard program flow here...CATCH [BEFORE UNWIND] some_exception another_exception [INTO oref].    ...react to the exception here...[CLEANUP [INTO oref].]    ...cleanup here before passing the exception...ENDTRY. ...
