Planual rules regarding Contents.

Users should only enter data and navigate through the Anaplan UX to prevent unintended access to hidden model objects. Remove access to all modules in the Contents panel for all end-user roles.
Engine Applicability: Classic Hyperblock and Polaris

To reduce maintenance, create separate functional areas for dashboards and modules (for example, Reports and Report Modules). Consider if you want new content to appear automatically for the end users.

For example: In the Contents tab, turn Show New Content "On" for all dashboard functional areas and "Off" for all module functional areas. New dashboards will then automatically be added to the Contents when the role security is updated, but modules won't.

Turning the "New Content" to "Off", allows development of new content without disruptions to the end users. You can then activate the new content at the required time.
