Since Untis 2018, you can shift substitutions in the timetable. Just drag the respective substitution to another position in the timetable. The following scenarios are possible:
How to shift a scheduled substitution
You already have scheduled a substitution for an absent teacher. This substitution is now to take place at another point in time. Just drag this period in the class or teacher timetable to the required position. In the substitution list, a cancellation is caused at the original position of the period, and the new position causes a shift.
If you delete the absence which causes all this, the shift remains.
How to shift an open substitution
You also can shift a substitution which has not yet been scheduled directly in the timetable. If the absent teacher is available at this later point in time, he/she will automatically be scheduled as substitute teacher.
If you prolong the absence of this teacher retrospectively because he or she is not available any more, an open substitution is generated again at the position where to you have shifted the period before.
How to shift open room substitutions
If you want to shift an open room substitution, you do the same as you will do with shifting a teacher. If you drag the period to a position where the room is available, it will automatically be assigned to the open substitution. This is a possibility for solving bottlenecks caused by the fact that a subject room is not available on short notice, simply by shiftings in the respective class or teacher timetables.
