If the Collection No. field of the current Master has been filled in, you can enter a Shipment Date Code into this field.
If Create Collection Relation Automatically
in the Inventory Setup has a check mark, a Collection Master Relation related to this Shipment Date Code
will be created automatically when you leave the Master Card.
In this case you cannot remove the Shipment Date Code from the
Master, unless the Collection Master Relation
related to the Shipment Date Code is deleted.
