Lesson 'PE - 9A': 6 instances with max 1 per day requires at least 6 days, but the maximum allowed is 5 days.

At a glance

The lesson cannot fit within the allowed number of days given the per-day limit.

What causes this error

This lesson has a rule limiting how many times it can appear on the same day (COURSE_MAX_PERIODS_DAY). Given the total number of weekly instances, the lesson needs to be spread over more days than the COURSE_MAX_DAYS rule allows.

Example: 6 instances with at most 1 per day requires 6 days, but the maximum is 5.

How to fix it

  1. Increase COURSE_MAX_DAYS — Allow the lesson to be placed on more days.
  2. Increase COURSE_MAX_PERIODS_DAY — Allow more than one instance per day, reducing the number of days needed.
  3. Reduce the lesson frequency — Decrease the number of weekly instances.
