COMMUNICATION_FAILURE during a Webdynpro BAPI call?

I have created a simple WebDynpro application that calls a BAPI. However, i am getting an error as RFC is not setup.

How do i setup the RFC call?

Error: The URL call http://crmehp.sat.com:8024/sap/bc/webdynpro/sap/zwd_bapi_call was terminated because of an error. 

The following error text was processed in system EH5 : RFC Exception COMMUNICATION_FAILURE with Message RFC destination BAPI Call does not exist. Occurred 
◾ The error occurred on the application server CRMEHP2_EH5_24 and in the work process 0 . 
◾ The termination type was: RABAX_STATE
◾ The ABAP call stack was:

Calling procedure bapi_flight_getlist in WDDOINIT method of webdynpro:

method WDDOINIT .
  DATA lo_componentcontroller TYPE REF TO ig_componentcontroller .
  lo_componentcontroller =   wd_this->get_componentcontroller_ctr( ).

    lo_componentcontroller->execute_bapi_flight_getlist(
     airline =    'AA'                       " bapisflkey-airlineid
*     destination_from =                  " bapisfldst
*     destination_to =                    " bapisfldst
*     max_rows =                          " bapisflaux-bapimaxrow
    ).

endmethod.

  CALL FUNCTION 'BAPI_FLIGHT_GETLIST'

I checked sm59 and a BAPI Call RFC dosen't exist. However, there are other RFC connections that work.

Solution

  • Assuming you don't want to call a remote system:

    Change

    DESTINATION  'BAPI Call'

    To

    DESTINATION  'NONE'

    If it is a remote system, create a destination in SM59 (but without the space) and reference that instead.
