Is there a way that the discount for each item will be zero? This means I would like those specific items should not be given or encoded any discount.
The max discount says 0 but users can still encode discount rates on it.
Anyone has an idea where to setup it in the system?
let me try this. I just found out the discount field on the pricing rule. However, I think this will still not solve my concern if I have multiple item rows then I need to ignore the pricing rule.
There are items that should not be applied of any discounts with or without a pricing rule.
