Example Programs with Asynchronous BAPI Calls
The following example programs show how receivers are determined with asynchronous BAPI calls.
The function ALE_BAPI_GET_FILTEROBJECTS must be used if the application's filter object types are not known at runtime.
A COMMIT WORK must be executed in the program after the outbound function module of the generated BAPI-ALE interface has been called. The 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 it will not be dispatched.
The IDocs created are locked until the called transaction has been completed. If you want to unlock them earlier, you can call the function module:
DEQUEUE_ALL
releases all locked objectsEDI_DOCUMENT_DEQUEUE_LATER
releases individual IDocs whose numbers have been transferred to the function module as parameter values.Filter Object Types Are Not Known at Runtime
