The Line Item Detail - Location field displays the Location from the item's Inventory database record.
To edit the Location, press [Ins] from the Location field on the Line Item Detail screen and select the desired Location from the Locations Lookup List. Editing the Location on the Line Item Detail screen changes the Location for the current line item only. It does not change the Location field in the item's Inventory database record.
