Creating Discounts Based on Categories
Categories can be used to create category-based discounts, where the same discount applies to all products in a certain category (or several categories).
You can define the Max discount percentage in individual category’s settings to define the maximum discount that can be given for the products in the category. See Maximum Discount Rules for information on how the maximum discount limit is applied in a POS.
For detailed information how to create discounts, see Creating a New Discount.
