Use this form to remove inventory that has been assigned to a shipment. The inventory can either be: returned to the pick list to be added to a new shipment; removed from the shipment, not returned to the pick list, and moved to a different location (the item cannot be added to a new shipment through the original pick list); or just removed from the shipment (the inventory was moved by some other transaction and the shipment is being updated to reflect this fact).
