If I generate a purchase return of an item to a vendor and I don’t have quantity of that inventory in stock I don’t get a warning until I generate the pick. Example: You create a Purchase Return Order and Release the order. You are then able to generate a Warehouse Shipment from this return order. You are not stopped until you attempt to generate a pick for the item.

This is very inefficient to not get a warning until three steps into the process. There should be a warning message “You have insufficient quantity of item XXXX on Inventory” prior to generating a pick for the item.
