History Tracking

From the History Tracking dialog, you can enable/ disable:

For example, entering 12 months in the Activity field means that Activity records must remain in the system for this period of time. After this time, accessing the Historical Record Maintenance dialog and clicking OK will delete records such as every time an employee opens a resource, takes a Practice Assessment, takes a final Assessment, etc.  In other words, all activities over 1 year old will be deleted to control the size of the database.
