Group '5A' on Monday: only 2 slots available but the minimum required is 4.

At a glance

A specific day does not have enough free periods to satisfy the minimum lessons per day rule.

What causes this error

The class group has a rule requiring a minimum number of lessons per day (MIN_PERIODS_DAY). On the specified day, the group's unavailable periods and time restrictions (earliest start, latest end, min/max lessons per day) leave fewer available slots than the minimum required.

How to fix it

  1. Reduce the minimum — Go to Classes, edit the affected class, and lower the MIN_PERIODS_DAY rule.
  2. Free up slots — Go to Classes, edit the affected class, and review the unavailable periods and time restrictions for that day. Remove any unnecessary blocks.
