Hello PeerGynt,
Operator rights include function rights (such as operating the navigation menu), resource rights (such as operating devices and users), and data rights (such as operating custom view, performance view, and reports). Function rights have the highest precedence. IMC filters operators with the same function rights by their resource rights and data rights.
p.s Performance Management—Provides general device performance view and performance settings.
