Error message

For class 7B, you configured fewer lessons (14) than the minimum possible (20). Check the already configured lessons, or modify the minimum time interval.

What causes the error

In the class configuration, you set a minimum number of lessons per day. You can check this in the configuration table:

If the schedule spans 5 days, this means each class should have at least 4 × 5 = 20 lessons per week.

If fewer lessons are assigned, the system can't meet the minimum requirement, and this error is triggered.

How to fix it

You have two options:

1. Lower the minimum lessons per day – If there’s no strict requirement, reduce the value or set it to 0. Go to the class configuration section and adjust the setting for this class.
2. Add more lessons – In the lessons section, make sure the class has enough lessons to meet the weekly minimum.
