When you created an examination this way, Untis automatically generates substitution events. If you have neither changed the time range of the examination nior the teacher or the room, this means one examination and one cancellation of the original lesson.
If the examination lasts longer, for instance an hour longer, you will be asked before giving your confirmation in the window "New examination", if potentially clashing lessons should be cancelled due to the examination.
If you confirm with "Yes", the lessons of the class are cancelled. If you confirm with "No", both will take place at the same time, the examination and the lesson. Both variants are displayed in the timetable clearly visible for the students.
If you have chosen for the examination a room which is not available, you will be asked when confirming the examination, what you want to do next, a question you already know from other segments. If you want to use the room for the examination, select "Schedule the room without clashes (creates a room substitution)". This way, a room substitution is generated for the lesson which you have replaced from this room, and you can assign another room for this lesson.
In substitution formats which are used to inform students, you can surpress displaying cancellations of the original lesson in the case of an examination. Use the option "No cancellation when prd. replaced" in the page layout of the substitution format.
If you have chosen a teacher as supervision who already has a lesson at this time, and was therefore coloured in red in the list, an open substitution or a cancellation according to your substitution time grid will be generated automatically.
