Recalculation of the input price at the current exchange rate

Good afternoon. Initially in. Where does the price of a product come from? If after recalculation of prices, then it should be recalculated at the rate of the supplier's price

If the price is recalculated, it should be recalculated at the exchange rate from the supplier's price [/quote] From the process of selling goods. That is, the employee prescribes the input price of the goods in the process of posting, and posts the goods. In other words, if I understand correctly, the price is raised not from the supplier, but from the warehouse (process). They just sold the product, let's say at the exchange rate of 40 dollars. The system converted it into hryvnia. But after the exchange rate change, let's say by 42 hryvnias/dollar - the retail price in hryvnias is recalculated, but the purchase price is not.
