Catch System Exception

Former Member — Tue, 28 Nov 2006 11:58:02 GMT

Hello Guyz!

need info about handling system exception while making type conversion. for example, i have 3 variables, viz.

v1 type p,

v2 type f,

v3 type i.

now i am going to divide v2 by v3 and store result in v1, i.e.

v1 = v2 / v3.

all i need is, in this particular case, if system ever gives any exception and if so,then is there any existing system defined exception to handle this.

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

Smaple program:-

REPORT demo_catch_endcatch.

DATA: result TYPE p DECIMALS 3,
      number TYPE i VALUE 11.

CATCH SYSTEM-EXCEPTIONS arithmetic_errors = 5.
  DO.
    number = number - 1.
    result = 1 / number.
    WRITE: / number, result.
  ENDDO.
ENDCATCH.

SKIP.

IF sy-subrc = 5.
  WRITE / 'Division by zero!'.
ENDIF

Shane,

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.
