On that page, you can administrate and view your previously used awards. The button "Add used award" lets you create a new entry. In order to edit or delete an entry, click on the double arrow next to the entry. As value, indicate the saving that was realised by the use of the listed award compared to the purchase of a regular ticket.
Although that table serves for statistic purposes only, you should look carefully after it. For instance, savings reports are based on it, which constitute an important Management Information System on their turn.
When adding or editing an award, the box "Matching with account owner" is activated as standard. Thereby, the indicated number of used points is automatically deducted from the account holder. If no corresponding account is found, a warning message is displayed, otherwise a confirmation for the successful operation. When editing or deleting an existing award, the matching is activated as standard, too. A modified number of points will be matched and points will be recredited to the corresponding program of account holder if an award is deleted respectively.
If you deactivate the field, you should reduce the account balance of the account holder in the menu "Account data" by the used number of points. Like that, you prevent any user from trying to request another award with points that are no longer available until his account balance is updated on the basis of the next automatic update of his account balance.
