We are using odoo 14 enterprise verison.
We've just realised this issue, not sure if this is how odoo meant to be?
For example, a PS5 has a cost price of $500, that's the price set on the cost price and purchase line in the product setting (product template page)
But, for a large shipment we were able to get at $450 per unit, so we've updated our purchase order, but the cost price on our product setting page is still $500 as a standard.
When we received the shipment at $450 each, the product setting page automatically got updated to $500 by odoo.
We don't want it to update the cost price on the product setting page, as this was a special shipment, usually it would still cost $500 per unit.
Is this a common issue?
