Why can't I change my reservation online?

Cancel and change a booking via "My Bookings"

When bookings are changed or cancelled via my bookings, one has to take into consideration that a booking can only be cancelled if the booking has a status lower than 70. Changing a booking is only possible if a booking status is lower than 90. This cannot be overruled via a setting. Furthermore, when a booking is changed - and no other settings are configured - the booking will be changed to status 40 as well.
