Before you can assign module permissions, you must add a model role or roles. If you only have the default Full Access and No Access model roles, any user with Full Access to the model can access all modules within the model.
Once you add additional roles beyond the default options, whenever you add a new module, the default access for your additional roles in None. You must assign access to the module for any user without Full Access to open it.
You can view the current module access permissions in the Roles → Modules tab in the Users pane.
Modules display on rows and roles display on columns. A dropdown menu displays for role in the row for each module. None displays as the default selection for each module when you add a new role.
You can only assign module permissions for user-defined model roles. Full Access and No Access do not display on the Roles → Modules tab.
