Not so, let me explain with an example
There is a supplier Biotus, RRC 393
https://crm.dobavki.ua/admin/shop/products/14/supplier/The product is in stock from this supplier 2 postings
https://crm.dobavki.ua/admin/shop/products/14/storage/First of all, we need to sell from the warehouse, I put the priority on choosing the price from the warehouse + do not apply the RRP of the warehouse
https://crm.dobavki.ua/admin/shop/settings/recalculate-price/I'm doing a recount
https://crm.dobavki.ua/admin/shop/products/14/margin/Takes the goods from the warehouse, puts the sale price 1 in 1 as the purchase price, because there is no rule
And in this case, we need to take the RRP from the product card for this supplier, that is, 393
Turned off settings:
When recalculating prices for a warehouse, do not take into account RRP
Priority changed to supplier
Included them to show how we need. If you need to test - you can turn them on and click recalculate.
