How to Generate Invoices_Credits in an Alternative Currency

When generating invoices/credit notes for debtors which require their invoice charge in a different currency to the billing company's currency, the system will generate the invoice values in both the base currency of the billing company as well as the debtor's preferred currency. This is identified by the debtor having a currency code. If a currency is not added or is removed from the debtor, the invoice values will only be generated in the billing company's currency.
The currency values will be generated for all types of invoices and credit notes automatically if the following conditions are met: Currency Codes have been activated
An exchange rate has been configured for the debtor's preferred currency
The debtor has a currency code applied
Where the above conditions are met, to determine the currency values, the system will:
Retrieve the currency exchange rate as at today's date for the debtor's preferred currency
Calculate the converted currency values for each invoice item and apply the rounding rules that have been configured. Sum the converted invoice items for the invoice total values.
This process will occur in the following places: Invoice Batch (timesheet based invoices)
Manage Invoice/Credit Notes (non timesheet based invoices/credit notes)
Credit ReBill (timesheet based credit notes)
