IMPORTANT - Discount hierarchy
If you need to specify more than 1 type of discount you need to know the order in which they are applied. There is a hierarchy where one discount overrides the other.
Prices set within the customer screen here, will override the individual product prices you may have set in the supplier screen.
The order goes from least specific to most specific:
•Product Discount •Discount Band •Catalogue Discount •Product Prices |
