You can limit access to certain regions within the MODELER and ADMINISTRATOR Modules by user or user-defined role. When restriction is applied to a user-defined role, all the users belonging to that role will inherit the restrictions.
To set restrictions, navigate to the Restriction node under User & Group in the ADMINISTRATOR Module. By default, Full Access is checked, meaning all regions are accessible.
To limit access, simply click the Configure drop-down to select a user or role. Then check the appropriate regions under MODELER or ADMINISTRATOR.
Click the Save button at the top-right corner when you are done. Now when navigating to MODELER, the selected user will only have access to the restricted regions.
