Changes in the definition of lessons and the scheduling of lessons are displayed in two different dialogues. In the picture below you can see that there has been only one change (L-No. 96). The columns "Classes", "Teachers" and "Subjects" refer only to the definition in the .gpn file.

If there have been changes in the timetable they are displayed in a separate dialogue.

As you can see in the picture the scheduling of one lessons (L-No. 31) has been changed in the database. In the .gpn file the scheduling of the lessons No. 37 and 46 has been changed.
