# Currency Exchange Rate Table (CURRENCY.CONTROL)
Read Time: 1 minute(s)
The CURRENCY.CONTROL procedure is used to define exchange rates between the domestic currency and foreign currencies which may be used in the system within order entry ( SO.E ) and purchasing ( PO.E ). They can also be used in invoicing, AP entry, cash posting, and check processing. The exchange rates are carried in the individual order records based on the exchange rate within this table at the time the order is entered. For example, EURO might be the code for the single European currency with an exchange rate of .7806 Euro to the dollar.
The exchange rates should be updated on a regular basis. A batch process exists to mass update open orders with foreign currency codes, to reflect updated exchange rates if desired.
