I have a reader with a special requirement. As an example, one part has a 1-4 price, a 5-9 price, and a 10-24 price. The part can be sold individually but is also part of several kits.
The Kit Price Unit needs to be the sum of the unit prices times quantity per kit for each part.
Now a customer may order 3 kits and 4 of the item by itself. He wants the kit re-priced as well as the line for 4 each, all to be priced at the quantity 5-9 price (as seven units were sold, one per kit in this example).
Has anyone seen anything like this?
