Changing a order is the action of updating a subscription; a Younium order.
One of the benefits of using Younium is that Younium will do parts of your financial accounting and revenue recognition. Changes to orders must be created as events. These events will generate output in your journals and at a later stage recognized in your bookkeeping. The result is then that your KPIS and books will be updated with the correct values. The action of updating any value on your order is called a change order.
