How do you handle exceptions in ABAP programs?

ABAP provides mechanisms to handle errors that might arise during program execution. Here’s how you can handle exceptions:

TRY… CATCH… ENDTRY: This block structure allows you to define a code section (TRY block) where exceptions might occur and following CATCH blocks to handle specific exceptions or a general category (OTHERS). A CLEANUP block can be used for actions to be executed regardless of exceptions.

TRY.

OPEN DATASET some_file FOR INPUT.

… process data from file …

CLOSE DATASET some_file.

CATCH system-exceptions cx_file_not_found = 1.

WRITE: / ‘Error: File not found!’.

ENDTRY.

RAISE EXCEPTION: This statement allows you to deliberately raise an exception within a program to signal an error condition. It can be used with a message to provide more context about the error.
