RFC calling has failed.

[Former Member]

Hi experts,

I called a RFC function module from a remote system. In case if RFC failed because of some communication failure or some other reason then Will the RFC return SY-SUBRC value in case of failure other than 0 (Zero)? Or How can I identify the failure?

Thanks in Advance.

HI,

Here is the scneario which you might be having.

CALL FUNCTION <your remote function module>

STARTING NEW TASK <give some task name>

DESTINATION <provide destination system you are calling>

PERFORMING <yoursubourtine to get online status of your remote call> ON END OF TASK.

....

....

FORM <yoursubourtinename> USING <Task Name>.

RECEIVE RESULTS FROM FUNCTION func

IMPORTING F1 = A1

EXCEPTIONS SYSTEM_FAILURE MESSAGE SYSTEM_SMG.

SET USER-COMMAND 'OKCD'.

ENDFORM.

Above logic in <yoursubroutine> willl get back results from Remote Function Module call which provides online status of your remote call.

Let me know if you have any questions.

Best Regards,

Krishna

      CALL FUNCTION <fm name>
        DESTINATION w_rfcdest
        EXPORTING
         ....................
        EXCEPTIONS
          function_not_exist    = 1
          communication_failure = 2
          system_failure        = 3
          resource_failure      = 4
          OTHERS                = 5.

You can add these exceptions while calling the RFC( though they may not be declared in the FM)

and check the SY-SUBRC

Hi Bharati,

There are no exceptions defined in the Function Module for exception handling on remote system and I am not authorized to change the called function. And I think SY-SUBRC will not work here.

Thats what I have already said.

You dont have to modify the original RFC.

But while calling the RFC, you can add these Exceptions as I have mentioned.

Hi,

have a look at this thread:

and check as well fm RFC_VERIFY_DESTINATION.

Best regards.

Hi deepak, go to the ST22 t-code, there you have a error description. When you get it, let me know your feedback.
