Create reports other than rehearsal and performance reports

No. A report template can be about anything you report on: daily work calls, department meetings, box office, a production meeting. Rehearsal and performance reports are just the most common.

To make one, go to Reports > Reports Administration and click Create a New Template. You'll need the Manage Report Templates permission for that production. Pick the standard fields you want (Manager, Date, Space, House Count and so on) and add run times if they help.

The standard fields keep their names, but the Other Fields and Departments are yours to title however you like. That's where a box office report gets "Tickets sold" and a rehearsal report gets "Costumes" or "Sound".
