Changing the main reservation's start / end times
This topic describes the consequences of changing the main reservation's start/end times with regard to the respective sub reservations and visitors.
When changing the start time, the subs of all types reflect the main reservation's start time changes. In other words, if the main reservation moves to an earlier or later time, all subs also move along (if possible).
However, when moving the end time of a main reservation this behavior only applies to subs of the type Reservation. For any other type of suborder (such as a work order), the end time is not affected by changing the end time of the main reservation. If a start/end time and/or occupancy conflict arises for the changed subs (Reservations, Orders), an error will be displayed.
The expected arrival/departure time of visitors linked to the reservation will change in parallel with the start/end date time of the reservation. If there is a start/end conflict, you will receive a warning.
The following example illustrates this by providing two scenarios:
