There are three exchange rates that the program uses when consolidating the financial statements of business units if the financial statements are in a foreign currency. They are the income statement exchange rate, the balance sheet exchange rate and the last balance sheet exchange rate. You must enter the appropriate exchange rate before consolidating. Before you can enter the exchange rate, you must enter information about the relevant business unit.
Open the 
Business Unit
List window.
Select the line with the relevant business unit, and then click Exch. Rates, Average Rate... or Closing Rate...
In the window that appears, the contents of the Relational Exch. Rate field have been copied from the Curr. Exchg. Rate table, but you can modify them.
