When I add a product, with a cost price as 10 and unit price as 15, the purchase order calculation should happen based on cost price which is 10*1 = 10 but at the moment it happens as 15*1 = 15

I have to manually modify this each and every time and is time consuming.

Also, for a product that is already added if the unit price is changed, there is no where i will be made aware as the unit price value is not displayed when the product is selected in the product details field of purchase order form.

Request your assistance.

Thanks
