Define Order Confirmations for Inbound Deliveries
If Warehouse Management is decentralized, inbound deliveries are generated in R/3 (which is the ERP system) that are distributed to the Warehouse Management System (WMS) and are then used as a basis for transfer orders during picking.
Up to now, inbound deliveries were either created automatically when shipping notifications were received in the system through IDocs or manually if confirmation control in Purchasing is set accordingly.
If your company does not use shipping notifications or uses them only in rare cases, you can generate inbound deliveries automatically from purchase orders.
In particular, this procedure is necessary for decentralized warehouses, since all inbound deliveries for which a WM transfer order is to be created, are distributed to the WMS.
You can set up your system so that inbound
deliveries are only created automatically for plant/storage location
combinations for which decentralized processing is activated for the warehouse
number assigned.
