Currently when you untick the box to mark a product code or sales code as an archived item and not to appear in the active dropdown lists the product remains on the relative page amongst the other active codes.
My proposal would be to add a button / tab on the editing screen that any non active item (button unticked) are automatically moved across to from the active items. That or provide a filter option, although I see a separate tab being the better option as you can tab back and forth between product or sales codes without having to keep changing a filter view.
