, select Users and Roles.In the navigation pane, select the role that contains the permission.
In the details pane, expand the Permissions bar.
Switch to the General or Study-Based tab.
In the For permission list, right-click the permission and select Delete.
The permission is deleted from the role. Permissions that appear gray are inherited from a higher role and cannot be deleted unless you return to the original permission first. The changes are saved automatically when you switch context.
