How to query for Advanced Pricing details applied to a product?

HI

We are placing items on a order or contract.

Here, The consultants have configured advanced pricing for the items.

So, when the item is placed on the order, the advance pricing engine kicks off and gets the pricing for the item.

I know you can apply advance pricing in so many ways, Qualifiers, Modifiers, Discounts,Coupons, Attributes etc.

But how do we know which pricing elements kicked in deriving the list price on the order?

What is the query for finding out? (Basic Pricing - you can get it from List Line from a Price List) but how to get the details on how the advance pricing calculated the pricing for that item?
