Each project can contain many calendar databases, however only one of them can be active and only the active calendar will display in a tab. The active calendar is the one that is accessed when you click on the Calendar Database button.
If the calendar attached to a scenario is not active when that scenario is run, then it is made the active calendar.
You can set or change the active calendar in a number of different ways:
1. | Select View > Calendars from the application menu; click the calendar you want to activate and click the Activate button; |
2. | Click the arrow to the right of the Calendar toolbar button and select a calendar from the list; or |
3. | Run a scenario that makes use of the calendar you want to activate. |
