Matched Purchase Orders
When you create a requisition, enter the line prices in the functional currency. To match the requisition to a foreign currency purchase order, using the AutoCreate Purchase Orders window, you must change the line prices on the purchase order from the functional currency to the foreign currency. You must also enter the exchange rate information in the Purchase Order Distributions zone before approving the purchase order. If you do not enter an exchange rate, you cannot approve a foreign currency purchase order.
Oracle Purchasing converts all foreign currency amounts to their equivalents in functional currency before checking and reserving funds. Oracle Purchasing creates encumbrance journal entries in the functional currency
