The Line Item Detail - Product Code field displays the Product Code from the item's Inventory database record.
Editing the Product Code on the Line Item Detail screen changes the Product Code for the current line item only. It does not change the Product Code field in the item's Inventory database record.
Note: If the Merge Same Items Line Item Entry Parameter is set to any of the ON options (Warn, Auto, Auto - No Beep) and a line item's Product Code is edited in the Line Item Detail
screen, Keystroke does not merge newly added items with that line item unless their Product Codes are edited to match it. This allows for the sale of multiple units of the same Inventory item with different Product Codes on the same transaction without having to first disable Merge Same Items.
