To determine a unique receiver of a synchronous BAPI, the application program calls the function ALE_BAPI_GET_UNIQUE_RECEIVER.

The following mechanisms are effective:

• If no receiver is determined or if the BAPI is not found in the ALE distribution model an empty table for the receiver is returned.
• If the forwarded filter object types and filter object values are unable to determine the receiver correctly, an error message and an exception are returned (ERROR_IN_FILTEROBJECTS).
• If more than one receiver for the BAPI is determined an error message and an exception are returned.
• If the RFC destination for a logical receiving system has not been maintained, an error message and an exception are returned (NO_RFC_DESTINATION_MAINTAINED).
• If any inconsistencies have arisen in the distribution model due to Customizing errors, an error message and an exception are returned (ERROR_IN_ALE_CUSTOMIZING).
