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