In ABAP programming, some times we may need to validate and check RFC Destination before calling a function module, you can find useful information in this tutorial.

Required validations for RFC:

  • Check if RFC destination is available or not.
  • Check RFC destination connection is working or not.

Example programm to validate RFC destination

All the RFC destinations are stored in table RFCDES, we can check connection using function module RFC_PING (When ever you call and RFC, it will automatically validate connection, if you need to validate explicitly you can use this function module).


REPORT ZSAPN_CHECK_RFC.
DATA : WA_RFCDES TYPE RFCDES.
PARAMETERS P_RFC TYPE STRING.

START-OF-SELECTION.
  SELECT SINGLE * FROM RFCDES INTO WA_RFCDES WHERE RFCDEST = P_RFC.
  IF WA_RFCDES IS NOT INITIAL.
    CALL FUNCTION 'RFC_PING' DESTINATION P_RFC.

    IF SY-SUBRC EQ 0.
      MESSAGE 'RFC connection is perfect' TYPE 'S'.

    ELSE.
      MESSAGE 'RFC is not working' TYPE 'E'.
    ENDIF.

  ELSE.
    MESSAGE 'RFC destination dosent exist' TYPE 'E'.
  ENDIF.
