Please remove item cost on Vendor ID or at least do a better implementation. I dont want my sales representative to know my cost.
I believe the better solution here would be to use your permissions to adjust what they can and cannot see. For those retailers with many products that have multiple vendors it is incredibly helpful to be able to store those various costs with their vendor ids. Otherwise, you have to key in a cost anytime you order from a vendor that is not a default vendor.
