A proposed class runs only if enough people book it. The minimum decides only whether a session runs. Whether a session's time can be sold as other offers before anyone books it is a separate setting: see Sell this time as other offers.
Set the rule in Admin → Settings → Booking → Minimum bookings. The Minimum bookings row on the class page links to this single settings home.
Choose the offering and its minimum. A new minimum defaults to Team review, which leaves bookings confirmed while the team decides. To use the proposed-class behavior described here, open Advanced controls and choose Automatic cancellation. Set Cancel if still below minimum, hours before the start to the cutoff, from 0 to 720 hours. The team review must happen before that cutoff; by default it happens 24 hours earlier.
Existing proposed classes retain their automatic-cancellation choices. Courses do not have this setting: a course always runs as a whole run. See Minimum bookings and Inbox decisions for the setup and Run anyway action.
At the cutoff, a session that reached its minimum is confirmed and its Runs if row says Confirmed: it reached its minimum. A session below its minimum is cancelled the same way as archiving it: pass, class pack and membership uses go back to the customers, and they are told the class is cancelled. See Cancelling and Deleting Class Sessions for what happens to each booking.
To change one session, open it and click the value in its Runs if row. Leave the minimum empty to follow the class, or enter 0 so the session always runs.
The cutoff limits what you can change:
- A new proposal, on the class or a session, applies only to sessions whose cutoff is still ahead. Sessions already inside their cutoff keep what they had.
- A session cannot be proposed once it is inside its cutoff.
- After its cutoff, a session can only be set to always run.
- A new session, or one moved to a time already inside its cutoff, always runs.
