At the moment, the ITEM setup allows you to enter either a "Unit Price" or "Profit %" if you have selected "Price/Profit Calculation" to "Price=Cost+Profit".

"Profit %" is also considered Margin

However, when you set up Special Pricing, for that same ITEM, you can enter either "Unit Price" or "Cost-plus %" which is actually considered Markup...

Why would you use Margin, in one location and then Markup in another? Should these not be the same for continuity, or perhaps in general setup, let the user choose between Margin/Markup.
