We fixed an issue where users could add additional guests to an existing booking even after a departure had reached its maximum capacity. This caused negative guest counts and allowed overbooking.
What’s changed:
- When a departure is at full capacity, attempting to add another guest to an existing booking now correctly triggers a Business Process Error.
- The error message clearly states that no spaces are available, preventing overbooking.
- Creating new bookings from the Contact record or Departure continues to block over‑capacity bookings as expected.
This update ensures guest counts remain accurate and departures cannot be overbooked, maintaining data integrity and operational control.
