Allow to change drop shipment property on purchase request
AFAIK, at the moment drop shipments can only be created automatically under certain conditions. As many situations can occur, where I want a drop shipment under other conditions, there should be a manual trigger in each sale position. This must allow the supplier to be filled in and a purchase suggestion to be created.
