A new set of dates has been added to the discount setup. Booked From and To are used to restrict discount usage to reservations or items booked during a certain time frame. Start From and To are used to restrict discount usage to reservations or items that occur during a certain time frame. The Start date range is the new name for the date range that already existed in the setup. For office reservations both ranges are optional. If a range is filled in then the reservation or item dates have to fall into that range. If no range is entered then the discount can be applied regardless of the reservation or item date. For online reservations both sets of date ranges are mandatory. If a discount does not have a range entered then it is not useable online.
