Use this window to view all customer order lines that are available for shipment connection and if desired, connect them to shipments. The window will view order lines in the Released, Reserved, Picked and Partially Delivered state with a remaining quantity to be delivered. Then you can connect these order lines to shipments. In the first place, each line is connected to an existing appropriate shipment (e.g., where the shipment status, customer, ship-via, delivery address is correct), otherwise a new shipment is created and the line is connected to this shipment.
The quantity of an order line can be connected to several shipments in parallel in order to handle a limited transport capacity, a backorder situation where you want to prepare the next delivery in advance, a customer requiring a certain delivery schedule etc.
