Showtime Manager: How does the Resequence button work?

Click Re-sequence session numbers to assign session numbers sequentially to future sessions. Sessions that are inactive, or already have transactions or bookings are not re-sequenced; this includes sessions with transactions in progress, or if a refund has occurred. Sessions on the same screen and business day must have different session numbers.

The system setting UseShowNumbers must be set to either R or D to enable this functionality.
