Exception Handling

Former Member — Mon, 04 Apr 2005 18:15:12 GMT

Right now i'm studying the eLearning Material located at the ABAP Section (for more info: https://www.sdn.sap.com/sdn/developerareas/abap.sdn?node=linkDnode6-3)

I got a doubt reading this stuff. How i can use the methods of the Exception GET_TEXT and GET_SOURCE_POSITION that belongs to the exeption's class?

  TRY.
     Z = 1 / 0. "ZERO DIVISION    
 
    CATCH cx_root INTO ex.


  ENDTRY.

Where CX_ROOT has 2 methods of it own: 1) GET_TEXT, 2) GET_SOURCE_POSITION

Any idea?

Hi Carlos

Inspect this standard example:


...
parameters NUMBER type I.

data RESULT type P decimals 2.
data OREF type ref to CX_ROOT.
data TEXT type STRING.

start-of-selection.

  write: / 'Testing division and Sqare root with', NUMBER.
  uline.

    try.
    if ABS( NUMBER ) > 100.
      raise exception type CX_DEMO_ABS_TOO_LARGE.
    endif.
    try.
      RESULT =  1 / NUMBER.
      write: / 'Result of division:', RESULT.
      RESULT = SQRT( NUMBER ).
      write: / 'Result of square root:', RESULT.
      catch CX_SY_ZERODIVIDE into OREF.
      TEXT = OREF->GET_TEXT( ).
      cleanup.
        clear RESULT.
    endtry.
    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.
