Using EXCEPTIONS in functions.

[former_member204025]

Hi all!

I would like to use excepions in function modules, could you please explain to me how should I use it? If I pass an internal table if there is some error, I would like to have exceptions instead of get a dump.

Please let me know.

Thank you!

Gabriela.

For an example look at FM : AUTHORITY_CHECK_TCODE

look in the exceptions tab.. ok and not_ok are present..

in the source code based on some conditions they use Raise OK statement to raise the exception.

__________

if you are calling an FM just un-comment the exception section, which you get when u hit pattern and have call that FM in ur code.

in the exception tab:

add the exceptions... like READ_ERROR_EXCEP, or some other what ever you wish.

and in source code when the fail occurs.

use RAISE exceptionname.

like:

RAISE READ_ERROR_EXCEP.

hope this helps

Hi, Try this way. <li>Create function module with RAISE statement.

FUNCTION zget_marc_data.
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(WERKS) TYPE  MARC-WERKS
*"  TABLES
*"      IT_MARC STRUCTURE  MARC
*"  EXCEPTIONS
*"      NO_DATA
*"----------------------------------------------------------------------

  SELECT * FROM marc INTO TABLE it_marc WHERE werks = werks.
  IF sy-subrc NE 0.
    RAISE no_data.
  ENDIF.

ENDFUNCTION.

<li>Call this function module in the program.

REPORT ztest_notepad.
DATA: it_marc TYPE TABLE OF marc.
CALL FUNCTION 'ZGET_MARC_DATA'
  EXPORTING
    werks   = 'X000'
  TABLES
    it_marc = it_marc
  EXCEPTIONS
    no_data = 1
    OTHERS  = 2.
IF sy-subrc <> 0.
  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
