As all departments are collected in one set of data, it must be clearly defined which lesson belongs to which department. This is designated in the master data of the classes.

If classes are coupled in one lesson then the class which was entered first in the coupling defines the association to the department. In the lessons window in the column "Department" you can see which department the lesson belongs to.

A teacher can be assigned to several departments so that he can be employed by all these departments.
