Copy Calendar Dialog Box
The Copy Calendar dialog box allows you to create a new calendar as a copy of the one you selected.
The name of the selected calendar is displayed in the box and highlighted. Any characters you type replace the name that is displayed.
You cannot have two calendars with the same name in the calendar file. Therefore, if you click OK without changing the name, Open Plan displays an error message.
If you are working with hierarchical calendars, notice that you can change only the local portion of the name.
