First, make sure you have a copy of the schedule open.
- In the Rosterizer Pane, under Included Fields, add the Scheduled Services token.
- When you click on Generate Roster, a window will appear which will contain options for the Scheduled Services token.
- Specify the start and end of the time period during which you'd like to generate the list of people who have been scheduled.
- Make sure the "Completely exclude volunteers from this Email or Roster who are not scheduled for any position that matches the given criteria" option is checked.
Now only volunteers who were scheduled at least once during the period you specified will be included in your roster.
