This functin calls an ABAP function module via RFC:

Syntax Syntax

    2. 

  2. RFC_RC  SAP_API   RfcCall(RFC_HANDLE	handle,
    3. 

  3. 	char *	function,
    4. 

  4. 	RFC_PARAMETER *	parameters,
    5. 

  5. 	RFC_TABLE *	tables);
    6. 

    7. 

    8. 



End of the code.


The structures RFC_PARAMETER and RFC_TABLE contain names and descriptions of the 'exporting' parameters and tables
specified in the function's interface. Tables can only be internal ABAP tables. The function returns after the call-request is sent. If the function returns RFC_OK there is no guarantee that the call has already been received by the target system.


This function is defined in SAPRFC.H.


Return Value:


  • Returns after sending the call request and returns either RFC_OK or RFC_FAILURE
    





Function Parameters:


  • handle
    connection handle
    

  • function
    function module to call
    

  • parameters
    'exporting' parameters
    

  • tables
    'tables' parameters
    

    Note Note
    RfcCall can fail because you called RfcOpen with an invalid password. See RfcOpen for more information.
    

    End of the note.
