FieldStack contains 3 different receive/send setups. These are set at the location level.
Loose - User can type in a tracking number, choose a tracking number or leave tracking number blank. FieldStack uses hieristics to match the receives and sends up against active Purchase orders.
Request PO Look-up - User is asked to choose a tracking number from a list of open orders, but can enter a tracking number free form. The user can't leave tracking number blank. If user choose tracking number, all receives or sends are tightly bound to the order.
Tight - User must choose from list of tracking numbers. All receives and sends are tightly bound to the order.
In options 2 and 3 items received or sent against an order that aren't part of the order are added with an order quantity of 0 and and "left" quantity of either -1 for receives or 1 for sends. On the items history you will now see a different looking reference/tracking number. It will store as something like "ÖÑ 3 24104ÖÑ" instead of 324104.
