Hi Team, we are using JDE 9.2.0.

What is the Requirement: the requirement is that the business has 7 critical items. If the customers orders any 5 items out of 7 , then customer will get some X percent of Discount. Minimum 5 items with at least 1 qty of each item.

Can some one help me to know how to do the setup Basket Pricing.

What are the challenges: Here the customer can order either 5 items or 6 items or all 7 items.

First Challenge: when we started the set up, first challenge is that there are 21 combinations if the customer orders only 5 items out of 7.

6 combinations if customer orders any 6 items out of 7 and 1 combination of customer order all 7 items.
