Example Programs with Asynchronous BAPI Calls
The following example programs show how receivers are determined with asynchronous BAPI calls.
Filter object types are not known at runtime
Receiver determination with Business Add-In
Filter object types are known at runtime
Note
The function ALE_BAPI_GET_FILTEROBJECTS must be used if the application's filter object types are not known at runtime. Otherwise its use is optional.
End of the note.
Caution
A COMMIT WORK must be executed in the program after the outbound function module of the generated BAPI-ALE interface has been called. A database commit at the end of the transaction is not sufficient. If a COMMIT WORK is not executed, the IDoc is created with the correct status but is not dispatched.
The IDocs created are locked until the transaction has been completed. To unlock them earlier, you can call the following function modules:
DEQUEUE_ALL releases all locked objects
EDI_DOCUMENT_DEQUEUE_LATER releases individual IDocs whose numbers have been transferred to the function module as parameter values.
End of the caution.
