Automatic MDM (CREMDM04) generation after saving of a vendor master

Hello experts,

does anyone know a solution for an automatic generation of a CREMDM04 IDoc after the commitment of a vendor master creation or change. We only find an userexit before the commit of the changes within the vendor master? The goal is to create the IDoc in a synchronous way by save the vendor master.
The only possible way we found until yet is to create a periodic report and work with the normal change pointers of the vendor master to create the IDoc (asynchronous).
