4th Currency
- Click the 4th Currency tab in the Ledger Setup (LES) dialog.
 - 
            Specify this information: 
		  
            
- Rate Type equal to Value 2
 - This option is only relevant when the fourth character of the currency code is used to signify a rate type.
 - If this option is set, a change in rate type for value 4 is copied to value 2.
 - Calculate from Fourth Amount
 - If this option is set, neither base currency nor transaction currency amounts in Ledger Import (LIM) and Ledger Entry (LEN) can be present without a fourth currency amount also being present, and fourth currency is used as the basis for calculations of amounts and rates.
 - Clear when Fourth changed
 - If this option is set, all non-fourth currency amounts and rates in Ledger Entry (LEN) are deleted if the fourth currency code or amount are amended.
 - Consistent within Trans Ref
 - If this option is set, the same fourth currency code is used in Ledger Import (LIM) and Ledger Entry (LEN) for all transaction with the same Transaction Reference.
 - Default totals to Fourth
 - If this option is set, the totals displayed in Ledger Entry (LEN) default to fourth currency totals.
 - Absent rate returns to Fourth
 - If this option is set, the cursor returns to the Fourth Currency Code field in Ledger Entry (LEN) if a required rate is not entered.
 - Balance Fourth first
 - If this option is set, priority is given to fourth
                        currency when balancing in Ledger Entry (LEN) for: 
- presets and line validation, if period, transaction, or journal balancing is specified.
 - posting.
 
 - Restrict recalc. of Fourth
 - If this option is set, the fourth currency amount is not recalculated if conversion code, account, period, date or amounts are changed in Ledger Entry (LEN).
 - Clear if Trans/Fourth changed
 - This option determines how Ledger Entry deals with Value 4 when you modify an entered journal line if you change the Value 2 amount, and vice versa. If this check box is checked, and you change a Value 2 amount, then the Value 4 amount is blanked out; similarly, if you change a Value 4 amount, then the Value 2 amount is blanked out.
 - Leave this check box unchecked to recalculate Value 4 on an entered line if Value 2 is modified, and to recalculate Value 2 if Value 4 is modified.
 -  
					                   Note: If either of the check boxes Calculate From Fourth Amount or Clear When Fourth Changed are checked, then the Clear if Trans/Fourth Changed is not activated in Ledger Entry (LEN).
 
 - Save your changes.
