When location data security is set to "Read Only" for an organization and the user's location has been assigned additional location access to a location with maintain rights, the user can maintain all cases and clients in their own location as well as the additional location and the child locations of the location. An Administrator may also choose to apply the additional location access to all sub-locations, and if so then the users in sub-locations of the location granted access can maintain all the cases and clients in their own location as well as the additional location. The assignment of additional location access with read rights is not applicable as the user can already view the cases and client information of the other locations.
