In items - I know it's possible to have a minimum quantity for a sell but is there a way to have a minimum quantity for the purchase? Or a minimum base amount? My example is as follows: Our minimum sell is $ 30 and the sell unit price is $ 0.25. So in the Minimum Quantity I have 120 units. My minimum purchase price is also $ 30 but my cost is $ 0.15 per unit. How can I define the minimum purchase price in this case?
