Diagnosis
The serialization check showed that a later IDoc has already beensuccessfully processed for this shipment.

System Response
This IDoc has been replaced and therefore has not been processed.
Because the most recent state of a shipment is transmitted in full andprocessed when a changed shipment is transmitted, the transmitted IDoccontains the changes and has already been processed.

Procedure
No further activities are necessary because the state of the shipment inthe SAP system corresponds to that of the shipment in the planningsystem.
