Diagnosis

For the respective item, however, no plant was specified or derived.

System Response
The plant is required in order - together with the storage location -to derive the feature 'warehouse number'. Since no plant is containedin the item, the system cannot determine a warehouse number either.
The workload data is updated with the initial value for the feature'warehouse number'.

Procedure
You can change the sales document item &V1& subsequently. If a plant iscontained in the item after you have saved it, the respective databaserecord with the initial value for the feature 'warehouse number' isreduced by the load from the item.
The system attempts to derive a warehouse number from the new plant. Ifthis is successful, the system also creates a new database record withthe item workload. If this is not the case, the system increases theinitial value for the warehouse number in the database record by theload from the item.
