Manufacturing industries often have specific Labels for the pair product-client. At the moment Sage X3 does have the possibility to have a label on units separator as a default one for stock and one per package (which we can relate to the client), but this solution force the client to create different packages in order just to define a different label which is on and agile solution.
If X3 could have a label field on ITM-BPC relation integrated with manufacturing and sales flow would be a nice feature in order to produce with the right labels when we produce to an order (make to order flow) and when we prepare the shipment.
