Group '6B': configured 18 lesson slots but the minimum required is 20.
Last updated: Mar 23, 2026
At a glance
This group has fewer lessons than the configured minimum.
What causes this error
This class has fewer lessons assigned than its configured minimum requires.
Example: if a class has Min. lessons/day = 4 and 5 active days, the scheduler requires at least 4 × 5 = 20 lessons per week. Assigning fewer than 20 lessons to that class will trigger this error.
How to fix it
- Add more lessons — Go to the Lessons section and add more lessons for this class until the total meets or exceeds the required minimum shown in the error.
- Lower the minimum — Reduce the Min. number of lessons per day in the class settings to decrease the required threshold.
