Currency Daily Rates (CND)
       You can create any number of daily rates for each currency code. You can define
         rates for different days and account ranges.
   
      Daily currency exchange rates are only used for a currency, if the Use Daily Conversion Rates option is set to Yes for the currency in Currency Codes (CNC).
Note: 
          You should also create a period currency
         rate using Currency Period Rates (CNP) to be used by the Ledger
         Revaluation and financial reporting functions.
