Hi,

HI,

Catchable runtime errors are handled with CATCH SYSTEM-EXCEPTIONSusing the name of the runtime error. To detect semantically related runtime errors using a common name, they are combined into exception groups.

You can handle catchable runtime errors in an ABAP program using the following control statements:

CATCH SYSTEM-EXCEPTIONS exc1 = rc1 ... excn = rcn.

...

ENDCATCH

Check the sample code to handle the exceptions.

REPORT ZTEST.

PARAMETERS number TYPE i.

DATA: result TYPE p DECIMALS 2,

oref TYPE REF TO cx_root,

text TYPE string.

TRY.

IF ABS( number ) > 100.

RAISE EXCEPTION TYPE cx_demo_abs_too_large.

ENDIF.

PERFORM calculation USING number

CHANGING result

text.

CATCH cx_sy_arithmetic_error INTO oref.

text = oref->get_text( ).

CATCH cx_root INTO oref.

text = oref->get_text( ).

ENDTRY.

IF NOT text IS INITIAL.

WRITE / text.

ENDIF.

WRITE: / 'Final result:', result.

FORM calculation USING p_number LIKE number

CHANGING p_result LIKE result

p_text LIKE text

RAISING cx_sy_arithmetic_error.

DATA l_oref TYPE REF TO cx_root.

TRY.

p_result = 1 / p_number.

WRITE: / 'Result of division:', p_result.

p_result = SQRT( p_number ).

WRITE: / 'Result of square root:', p_result.

CATCH cx_sy_zerodivide INTO l_oref.

p_text = l_oref->get_text( ).

CLEANUP.

CLEAR p_result.

ENDTRY.

ENDFORM.
