Using the Currency Rates (create) form (which can be invoked from the Currencies form by clicking the Currency Rates link) you can enter a new exchange rate for the currency.
The Currency Rates (create) form
In the Date field, specify the date starting which the new exchange rate is in effect.
In the Exchange rate field, enter the actual exchange rate of one unit of the foreign currency with respect to the national currency, that is how much one currency unit is worth in units of the national currency. The exchange rate is used as a multiplier.
The Factor field is populated with the default value of rate factor, 1, which is suitable for most currencies. For most currencies, the exchange rate for conversion to other currencies is defined on per one currency unit basis. For some currencies, such as Iranian rial, Colombia peso, Indonesian rupees, the rate is specified for 100, or 1000 units, or so forth because the unit value is too low. The Rate Factor parameter is used to address these issues. Use rate factor equal to 100, 1000, or 10000 for specific currencies with exchange rates defined for 100, 1000, or 10000 currency units, respectively.
If the exchange rate is expressed in the national currency, the amount in the currency to be converted is divided by the rate factor before the exchange rate is applied.
Example 1. If AED is selected as national currency in your system and the exchange rate defined for one US Dollar (USD) is 3.67 with factor=1, the amount of 1000 USD ($1000) will be worth 3,670 AED.
Example 2. With AED as national currency, the exchange rate defined for 100 Indonesian Rupees (IDR) is 0.026. Then factor=100, and the amount of 1000 IDR will be worth 1000/100 *0.026 = 0,260 AED.
