This POS option in Options Configuration determines if the Next Item button in POS uses the criteria you set up for the Next Item button in the Options Configuration window (these options are also found in Function NEX).
The settings are used after you enter an item, click Display, and then click Next Item.
Y = Use the settings in Options Configuration (same settings as in Function NEX).
N = Do not use the settings in Options Configuration (same settings as in Function NEX). Display the items in SKU order when you click Next Item.
