A lesson is longer than the entire school day.

What causes this error

A lesson has been configured with a duration that is longer than the total number of periods in a school day. A lesson cannot span more than one day, so this configuration is impossible to schedule.

How to fix it

1. Reduce the lesson duration — Go to the Lessons section and set a duration that fits within the number of daily periods.
2. Add more periods — Go to Periods configuration and add more periods to the day so the duration fits.
