You can update your existing operational area hierarchy or if no operational areas have been created yet, you can create a new operational area hierarchy, using the Operational Areas Import configuration page.
The Operational Areas Import configuration page is accessed via the Configuration menu.
Operational area nodes can only be deleted in the Operational Areas module. Operational area nodes removed from the import spreadsheet will not remove
the existing nodes from your j5 System. This is to prevent operational areas from
being removed accidentally.
