Organization calendars can be used as base calendars for projects, resources, and tasks. If an Organization calendar is referenced (in use as a base calendar) you cannot delete the calendar. If you cannot immediately delete the calendar because it is referenced, you can de-activate the calendar, which will prevent any new references. Then you can systematically switch the base calendar with a different calendar and eventually delete the Organization calendar once the references are removed.
Note: Must be user with administrative privileges.
To view references to an Organization calendar:
- Navigate to Admin/Setup/Calendars.
- Right-click on the calendar whose usage you want to view and choose References from the menu.
- Click the Projects tab to display a list of project calendars that use this Organization calendar as a base calendar. Click the Resources tab to display any resource calendars that use this Organization calendar as a base, and click the Tasks tab to display any tasks that use this Organization calendar. Note that this dialog will display up to 100 references; for a complete list of references, you can run a report using the base calendar field on project, resource, and task entities.
- Click OK to dismiss the dialog.
