We ship large items and we have to configure the shipment on a pallet (or pallets).
When we get the order, based on ship to location and carrier chosen, we may send on one pallet, two pallets or just parcel.
The PICKING SLIP - which is the same as the PACKING SLIP needs to be generated a few days before the shipment is actually ready but after invoicing. Some times the Shipment is done third party - which means we do not generate the label for it (based on customer).
How can I decouple creating a PICKING/ PACKING Slip from the actual SHIPMENT (entering tracking number, informing customer with tracking number etc.).?
