I have changed my price ie 1500/- to 1000/- in sales order. when i create delivery document it was showing 1500/- as PR00 price. But when i create billing document with reference to same delivery it will be 1000/- as PR00.
I checked up copy copy from Sales to sales, Sales to billing where pricing type is maintained. But i could not able to see where pricing type is maintain for Sales to Delivery copy control.
