RfcInvoke

Use

Executes a function module in the backend system so far. The return codes have the following meaning:

Return Code	Description
RFC_OK	The function call was executed successfully
RFC_ABAP_EXCEPTION	The function call was executed and ended with a defined ABAP Exception. The key of the exception can be obtained from abapException exception_key . In the above two cases rfcHandle is still open and can be used to execute further function call.
RFC_ABAP_MESSAGE	The function call was started to be processed, but was aborted with an ABAP Message. The message parameters can be obtained from abapException message_class , abapException message_type , abapException message_number , abapException message[0] , ..., abapException message[3]
RFC_ABAP_RUNTIME_FAILURE	The function call was started to be processed, but was aborted with a SYSTEM_FAILURE (e.g division by zero, unhandled exception, etc in the backend system). Detailes can be obtained from errorInfo message
RFC_COMMUNICATION_FAILURE	The connection broke down while processing the function call. Details can be obtained from errorInfo message . In these three cases the connection has been closed, so the rfcHandle needs to be refreshed via RfcRegisterServer.
RFC_INVALID_HANDLE	rfcHandle is invalid or points to a connection that has already been closed
