RAISE is a keyword used in SAP ABAP programming.This tutorial covers its introduction & syntax details.
RAISE
Basic form
RAISE except.
Effect
This statement only makes sense if used in conjunction with function modules.
It triggers the exception except .
If
the program calling the function module is to handle the exception (see
CALL FUNCTION ), control returns immediately to that program and the
EXPORT parameters of the function module are not assigned values.
Otherwise, the program terminates with a suitable error message.
Example
The function module STRING_SPLIT would look something like the code specified below (see also the example for CALL FUNCTION ):
FUNCTION-POOL CSTR.
FUNCTION STRING_SPLIT.
…
IF STRING NA DELIMITER.
RAISE NOT_FOUND.
ENDIF.
…
ENDFUNCTION.
The calling program may then contain the code:
PROGRAM EXAMPLE.
…
CALL FUNCTION ‘STRING_SPLIT’
* …
EXCEPTIONS
NOT_FOUND = 7.
IF SY-SUBRC = 7.
WRITE / ‘There is a problem.’.
ELSE.
…
ENDIF.
If
the RAISE statement in the function module STRING_SPLIT triggers the
exception NOT_FOUND , processing of the function module terminates and
returns to the calling program. In this case, the return code, which
you read directly after the CALL FUNCTION statement, contains the value
7.
