To make these changes we can not do it by dragging in the box, because only one day. To change a reservation date, we will enter the reservation, and click on the button at the bottom "move / change".
A window will appear where it gives us the date data , court and time.
We modify the schedule and save, if the schedule was incorrect or busy, the system would warn us.
The system will automatically recalculate the amount of the reservation and if it was already paid and the amount was higher, it would leave it unpaid only for the part we have added.
