I have done pricing scripts before based on external tables and UDT's. One could also evaluate each pricing technique using MAS tables after the quantity is entered and select the lowest price.  Basically, ignoring the initial result and redoing the price selection. Depending on which methods you need to check, the script could be complex.

Thank you, sir, but how do you mean to 'redo' the price selection? Is there a way in script to check a single pricing type? Like "what is the promo price? what is the customer/item contract price" etc ...?
