A Subscription is a group of Favorites that has been given a name and description. This Subscription name can now be used by Administrators and Advanced Users to assign this bundle of reports to one or more Roles. Only Advanced Users and Administrators can create Subscriptions, and only Administrators can assign the Subscriptions to other Roles.
Since subscriptions are built from favorite reports, there must be at least one favorite available to include in the subscription. If you don’t have at least one favorite in your list you must first designate one or more reports as favorites.
