Where does the selling price come from in Purchase Orders?

Purchase Order is created with current sell price. Before receiving the merchandise the sell price is changed in the item. When receiving merchandise unless I see that the sell price has been changed and change it myself the dollar amount will revert back to the old price.

Is there box I need to check somewhere to make sure that when receiving the merchandise Adagio grabs the current sell price on the specific item and not the one showing in PO?

Thanks,
Janie
