How can I grant permissions for teachers to create their own absences?

As administrator in "administration" > "rights and roles" (1) > "teachers" (2) there is a new section for substitution planning (3).

Here you can control if teaches are allowed to create or see their own absences.

The default setting is "read and create".

The english translation for this section is still missing (but will be updated soon).
Temporary translation here:

substitution planning

Are teachers allowed to manage their own absences?

• not allowed
• read only
• read and create
