In the timetable, lunch is set up to meet using entire periods and all grades levels have lunch during the same period. A lunch period is defined each day.
In the Pattern, lunch is not assigned to a block and no other blocks meet during the lunch period.
All students are assigned to the lunch period, but it does not have a block. So when viewing the Master Schedule by block, lunch is listed as having no block.

To create a block for lunch:
 

  1. Define a block  (BB134808) during the lunch period in the pattern.
  2. Create a course  (BB186893) for lunch, making it mandatory (BB143242) so all students are enrolled.
  3. Restrict the course (BB179246) to only be scheduled in the appropriate block.
