We use a large number of vendor trade agrements for price and discount which helps keep purchase orders/amounts/discounts nicely organised. However, we use standard cost for inventory valuation and have "latest purchase price" enabled to ensure an accurate purchase price on the item master. This is causing an issue with standard cost updates as it is the gross price which is reflected and therefore can lead to overvaluation of stock.
Does anyone have a method to ensure that updates are as accurate as possible but to ensure that trade agreement price and discount is applied as a combined field (i.e. nett)?
