Item Purchase Prices and Currency
When you do business with vendors who use multiple currencies in their business dealings with you, item prices on transactions are determined through the following process:
If an item price is specified for the transaction currency, this price is used.
If no item price is specified for the transaction currency, the base currency item price is converted to the transaction currency based on the exchange rate on the transaction.
If neither base currency nor transaction currency price is available, the price field is left blank.
