hello All,
Is there any function module available to check RFC destination is active or not?
Thanks,
Johnny

Hi Johnny,
You can use this FM <b>RFC_VERIFY_DESTINATION</b> if your release is greater than 4.6C.
Check this sample code from Craig Cmehil's weblog.
CALL FUNCTION 'RFC_VERIFY_DESTINATION'
  EXPORTING
    DESTINATION = TMP
        TIMEOUT = 10
  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 EQ '0'.
    "* Do code here
  ENDIF.
or you can also use this FM <b>RFCPING</b> and check this sample code from other thread.
DATA : IT_RFCSI LIKE RFCSI OCCURS 0 WITH HEADER LINE.
CALL FUNCTION 'RFC_PING' 
  DESTINATION IT_SLS-SYST
  EXCEPTIONS
    SYSTEM_FAILURE = 1
    MESSAGE RFC_MESS1
    COMMUNICATION_FAILURE = 2
    MESSAGE RFC_MESS1.
IF NOT RFC_MESS1 IS INITIAL.
  MESSAGE I000(YHPA0K) WITH RFC_MESS1.
ELSE.
  CALL FUNCTION 'RFC_SYSTEM_INFO'
     DESTINATION IT_SLS-SYST
     IMPORTING
       RFCSI_EXPORT = IT_RFCSI
     EXCEPTIONS
       COMMUNICATION_FAILURE = 1
       MESSAGE MSG_TEXT
       SYSTEM_FAILURE        = 2
       MESSAGE MSG_TEXT.
  MESSAGE I001 WITH 'Connection to '(029)
                    IT_SLS-SYST
                    'Succeeded'(030).
  ENDIF.
ENDIF.
Hope this will help.
