Costing can create variant and qty based pricing (sales, purchase and cost) that trade agreements can then override.I would advise that instead of item specific pricing use ListPrice+discount instead. It is much easier at an item group + customer group level. Item specific pricing by customer account is very difficult to maintain and update.That being said, DIXF is your best route. If there is no trade agreement entity in your system see if you can have a developer create one.We use ATLAS here, which is a life saver, but it has trouble handling more than 10,000 records at a time on a good day.
