If an allotment temporarily has a scope of 0, reservations can still be made from allotment as long as the tolerance period has been defined accordingly. In this period, reservations fall into the so called “gap”. Rooms booked in the gap are shown in a separate line.
Tolerance periods are defined by configuring registry keys [5946] and [5947]. I.e. this allows reservations x days prior or after the beginning or end of a contract or when the scope is 0.
