I created a scale pricing for the selling price, for example, 100 unit @2, 500 unit @1.5 and 1000unit@1. For the customer request, the want to separated into serveral items when creating sales order. e.g item 1 quantity 200 and item 2 quantity is 300. Actually, both item refer to same material. In this case, the scale price cannot be retrieved correctly. How can I retrieve the unit price @1.5 because the total quantity for this material is greater that 500. Thanks!
