Once you make any corrections OPERA Cloud recalculates the total custom charges appropriate for the reservation. If the existing Custom Charges are too much or too little, in comparison with the updated Custom Charge Exemptions, then OPERA Cloud automatically posts a Custom Charge Adjustment to compensate for the difference.
