Use this option to price items by adding a percentage increase to an item's buying price. The percentage is set at product group level and applies to the items in the product group.
You can use markup or a set price, but not both. Also you cannot discount goods that you price, using mark-up.
Open: Price Book > Selling Prices > Markup Pricing.
Select the Use Markup check box for the product group that you want to use markup pricing.
If the product group has associated discount, the discount structures and linked items are removed.
You must set up fixed selling prices for the price band instead.
