For "overbooking" on a room type, we mean a time frame in which the availability is less than 0. An overbooking is therefore composed of a set of reservations that being on the same type, whose periods of stay intersect exceeding the overall availability.
ZaK automatically identifies these overbooking periods and, for each of these, shows all the reservations involved.
In the example there are two Dbls available (101 and 102) but 3 bookings in this room type arriving on 22/09.
Zak looks out for a solution by checking if there is availability in another room type.
Overbooking can be solved by assigning an available room type to one of the bookings.
