You catch class-based exceptions in the statement block enclosed by the TRY and ENDTRY statements. To catch these exceptions, you define handlers within the specified TRY block. You introduce a handler using a CATCH statement, followed by the exception classes to be caught and the associated handler code. After the CATCH clauses, you can declare a CLEANUP clause. The statements in the latter clause will be executed if an exception is caught outsidethe TRY block. The structure of the TRY block is as follows:
TRY.
... guarded section
CATCH cx11 ... cx1n [INTO ex1].
... handlers for exceptions cx11 to cx1n
CATCH cx21 ... cx2m [INTO ex2].
... handlers for exceptions cx21 bis cx2m
... other handlers
CLEANUP.
... cleanup block
ENDTRY.
The TRY block is split into different sections using the CATCH and CLEANUP clauses.
TRY-CATCH-ENDTRY can be used to handle catchable exception, for example a division by 0. If you divide a number with 0, basically you will have a short dump. Using TRY-CATCH, oyu can continue your program run and will not have dump.
Example:
TRY.
SORT T_ERGEB-MSG_T_SAP_ACTIVITY-ITEM DESCENDING.
DELETE ADJACENT DUPLICATES FROM T_ERGEB-MSG_T_SAP_ACTIVITY-ITEM.
