Anchor Currencies
When a transaction involves two currencies that are not available as standard pairs from the selected rate provider, an anchor (intermediate) currency is used to compute the transaction. The source currency is converted into the anchor currency, which is then converted into the target currency. You can specific up to three anchor currencies in your accounting preferences when you check the Use Triangulation Calculation by NetSuite box.
NetSuite uses anchor currencies in the cross currency triangulation calculation. At update time in your selected time zone, NetSuite uses a web services call to contact your specified integrated rate provider. If your rate provider does not offer an exchange rate between a requested currency pair, NetSuite sends a second request to your rate provider. This request seeks exchange rates for two currency pairs: one exchange rate between the source currency and the currency specified in the Primary Anchor Currency field, and one exchange rate between the primary anchor currency and the target (base) currency. If your rate provider offers those two exchange rates, NetSuite calculates the triangulated exchange rate for the transaction.
If your rate provider does not offer exchange rates for the primary anchor currency and the two currencies in the transaction, NetSuite sends another rate request to your rate provider. This request seeks exchange rates between the source currency and the currency specified in the Secondary Anchor Currency field and between the secondary anchor currency and the target currency. If your provider offers those two exchange rates, NetSuite performs the triangulated rate calculation.
If your provider does not offer exchange rates using the secondary anchor currency, NetSuite sends a third and final request, substituting the anchor currency specified in the Tertiary Anchor Currency field.
Rate conversions that are available impact the exchange rate calculation.
You can specify any ISO standard currency as an anchor currency.
When you choose a currency in one anchor field, that currency is unavailable in the other two anchor fields.
If you do not choose an anchor currency, NetSuite provides only direct and inverse exchange rates. For information about these rates, see Direct Rate and Inverse Rate.
