While ARMS do not track individual views of a case report, the "History" button found on top of the Case Screen does track modifications and changes made to the data by a user.
In Desktop ARMS, it is located under Commands Menu.
Department can control what the users can view through the User Access setup by either completely settings certain sections of ARMS off limits (no viewability) to the user or by using the case filtering of Confidential, Sex Offence, and Juvenile to filter an individual case from the user completely.
