How to add exceptions to function module

[Former Member]

Hi Experts ,

I have a query , how to add exceptions to a standard function module when there are no exceptions provided by default . Also please let me know by adding exceptions can we just throw a message and will we be able to prevent the program from going into dump.

Hi,

It is not possible to add exceptions to std FM without raising for an OSS message. After getting the key for editing the FM u can add the Exceptions and can give some messages in the program after a sy-subrc check. But this is not recommended as this FM might be used in different programs.

Hi,

U can use Return code to avoid Dumb.

use PROCESS_MESS_GET_RETURN_CODE

or Search RETURNCODE* in SE37 find suitable FM to ur requirement

Hi Balaji,

As this is standard function module, I think you can't change its code, which will be required to raise some exceptions.

As for the second question if you use in FM such statement

RAISE exc.

Then after calling this FM you need to handle this exceptions, otherwise system will dump out.

CALL FM '....'
...
EXCEPTIONS
    exc = 2.

if sy-subrc <> 2.
   MESSAGE ....  'Exception raised'.
endif.

If you want to handle it inside the FM, you need to write like this:

MESSAGE .... RAISING exc.

After this when exception is raised system will end up the FM and the result is stored in sy structure

CALL FM '...'
...
EXCEPTIONS
      exc = 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.

As in previous answers, I do not advise you to change a strandard function module.

You can in an exit / Badi send an error message, the calling programs must intercept the exception ERROR_MESSAGE to avoid any dump.

Hi,

You can define your own exceptions and inside the source code.... use RAISE statement to show the message without going into DUMP.
