Field help (DEMDLVDAT1) 

This is the delivery date requested by the customer. This date is initially by the requested delivery date entered in the order header. The modification of this date will trigger the recalculation of the shipment date (Shipment date = Requested delivery date - Delivery lead-time) and will recalculate the planned delivery date (Planned delivery date = Shipment date + Delivery lead-time).

During the modification of this date, the system controls that this date does not correspond to a non-working day or an unavailable day for the shipment date. If this is a non-working day, the date will automatically be moved to a later date, in the other case a warning message is displayed.

Special features linked to the inter-company : In the case of an inter-company or inter-site order generated from a purchase order, the requested delivery date will be initialised by the planned receipt date entered in the purchase order line.
