Hi,

the easiest is to RFC call the following FM: SUSR_LOGIN_CHECK_RFC (if no user is specified the system will connect with the user defined in the RFC destination definition, e.g. ALREMOTE).

If your RFC doesn't exist, you'll get a dump with non handled exception CALL_FUNCTION_NO_DEST.

If it doesn't dump and don't return an exception then your RFC DEST is OK.

Otherwise manage the other exceptions in your code like below

DATA: rc LIKE SY-SUBRC.

TRY.
  CALL FUNCTION 'SUSR_LOGIN_CHECK_RFC'
  DESTINATION 'RFC_DESTINATION' "your RFC Dest
*   EXPORTING
*     BNAME                        = 'UNAME'
*     PASSWORD                     = 
*     XBCODE                       =
*     XCODVN                       =
   EXCEPTIONS
     WAIT                         = 1
     USER_LOCKED                  = 2
     USER_NOT_ACTIVE              = 3
     PASSWORD_EXPIRED             = 4
     WRONG_PASSWORD               = 5
     NO_CHECK_FOR_THIS_USER       = 6
     INTERNAL_ERROR               = 7
     OTHERS                       = 8.

*  CATCH 'CALL_FUNCTION_NO_DEST'.
  rc = SY-SUBRC.

  IF rc <> 0.
    IF SY-MSGID IS INITIAL. "dump
      MESSAGE ID 'NORFC' TYPE 'E' NUMBER '004'
      WITH 'CALL_FUNCTION_NO_DEST'.
    ELSE. "exception
      MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
      WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
  ELSE.
  MESSAGE ID 'RFC' TYPE 'I' NUMBER '000'
      WITH 'RFC DESTINATION OK'.
  ENDIF.
ENDTRY.

hope this helps...

Olivier.
