Admins can have notifications sent to themselves of any change to user names, Account Types, etc.
This is done from the Activity Logs page Activity Logs, by clicking Data Change Notifications.
Click Create Notification.
Choose the Data Table & Field Name and choose recipients. In this example, two recipients will be notified each time any workflow is approved. Notification is sent via email, listing the change made and date.
There are numerous options for data tables and field names. Some schools set up change notifications when a user is deactivated, a group is deleted, a user changes a first or last name, or an officer changes position.
In these cases, admins may not want to lock fields via Field Permissions, but they do want to stay apprised when these fields are changed.
