Use this tab to get a consolidated picture of how prices 
and discounts are fetched and used in calculating the line price, line total, 
margin, etc.
When a price query is called from the customer order and the sales quotation, the 
price query is populated with a snapshot of the pricing done on the calling 
line. When a price query is used standalone, pricing for entered customer, sales 
part, quantity etc, are displayed.
In the right pane of the tab you can view a graphical representation of the origin of the price. The area where the price is fetched will be highlighted and expanded automatically.
