the rate retuned by the currency.exchangeRate function does not match the rate found in the currency exchange rate table, any idea why?

currency.exchangeRate

function in NetSuite's SuiteScript API retrieves the exchange rate based on the parameters provided, which include the source currency, target currency, and date. The function returns the exchange rate that was effective on the date provided in the function call. If the rate returned by the

currency.exchangeRate

function does not match the rate found in the currency exchange rate table, it could be due to the date parameter provided in the function call. The function will return the exchange rate that was effective on the date provided, not necessarily the current or most recent exchange rate. For example, if you have a transaction in November but the exchange rate is set in August, and you provide the date of the transaction (November) in the function call, the function will return the exchange rate that was effective in November, not the rate set in August. Here is a sample code snippet:

javascript
var rate = currency.exchangeRate({
    source : transactionCurrency,
    target : approverCurrency,
    date   : new Date() // This should be the date of the transaction
});

If the date of the transaction aligns with the posting period, the currency FX is feeding off the date, whereas the posting period could be unrelated to the date. That's one reason this could be occurring. Also, please note that the exchange rate data might not be immediately updated in all parts of the system, which could also lead to discrepancies.
