This lesson has no room it can be placed in.
What causes this error
A lesson must be assigned to a room during scheduling. This error occurs when no room is available — either because the lesson has very specific room requirements, all eligible rooms are at full capacity, or no rooms have been assigned to this lesson.
How to fix it
- Check room restrictions — In the Lessons section, verify the room restrictions on this lesson. Make sure at least one valid room is selectable.
- Add more rooms — If all rooms are at capacity, consider adding additional rooms in the Rooms section.
- Review room capacity — Ensure available rooms are not already over their scheduled lesson limit.
