When performing long-term scheduling, scheduling teams must generally take into account that some teachers will already have other commitments on certain days. Timetable optimisation will take these days into account by not scheduling any lessons for the teachers concerned on these days.
Untis can take this into account by means of calendar absences .
The calendar absences window is opened using the button with that name in the calendar yearly planning window.
This window allows you to enter the start and end date of absences for teachers (and also for classes).

Absences will also be displayed in the timetable window provided suitable settings have been made.

Note:
Incidentally, calendar absences can also be entered via the school year calendar from the 'Master Data | Teachers' (or Classes) window.
