When you place a Purchase Order the price it shows is the price...This is wrong it should be the COST.

They told me you have to create a Price Book but that should not be because when you want to update a price then you have to update the price, the cost and the price list.

In the Product Module there is a Price and a Cost. So if you place a Quote the system  should look for the PRICE and if you place a purchase order the system should look for the COST.

I consider this is an error in the system.

Thanks for the comments...
