remote function call - catching technical exceptions

[rainer_hbenthal]

Hi,

i need to catch some exceptions in a customer report with a remote function call. Its for the business, presenting them a dump is not acceptable.

The remote function itself deliveres application exceptions - thats no problem.

But i would like to check some things in advance:

- is the remote system available?

- is a logon with rfcdest possible?

- does the function module exists?

Some things can be checked by

RFC_GET_SYSTEM_INFO

but at least may be someone has a better way of checking. Especially if the function module is in existance i do not have a glue on how to check that. I hoped that maybe there is a system exception which i can catch via TRY, but i douoldnt find anythin in the online help.

Hi,

Please check in SE38, some programs begin with SRFC* , maybe something you need.

I don't think there is a need of checking that before FM call. Each RFC function defines two implicit exceptions:

- COMMUNICATION_FAILURE

- SYSTEM_FAILURE

Both can be added to the list of catched exceptions so you would not raise a dump if for some commucation or other error occur.

Try it out.

Hi,

You can use the code below:

try.

Call Function "ABC" destination "XYZ".

Catch cx_root.

raise error.

endtry.

Hi,

before calling your RFC try using fm RFC_VERIFY_DESTINATION.

e.g.

.
  CALL FUNCTION 'RFC_VERIFY_DESTINATION'
    EXPORTING
      destination                = g_dest
    EXCEPTIONS
      internal_failure           = 1
      timeout                    = 2
      dest_communication_failure = 3
      dest_system_failure        = 4
      update_failure             = 5
      no_update_authority        = 6
      OTHERS                     = 7.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ELSE.
* then call here your RFC
  ENDIF.

.

Best regards.

in Addition to the helpful answers: catchable exceptions can be found in the online documentation for a normal call function. I just had a look in the rfc call function, but the normal ones are working fine even with destination.
