You can use subscriptions when you want to be notified automatically when an event happens. Subscriptions are associated with an object and the types of events that can happen to that object. Subscriptions are available for the following events:
To enable the subscription for an event, select the subscribe action when the corresponding object is displayed in the detail view. This displays a dialog screen used to select the subscription type you want to enable. Refer to the topics for the individual object types for specific information.
When you subscribe to events related to an object, the subscription applies only to that object, not to other objects below it in any hierarchical arrangement. For example, assume that a task has a number of subtasks. Subscribing to the top-level task will provide notifications that relate to that task only, not to any subtasks.
When an event you subscribe to occurs, you receive an email notification.
For information on how an administrator can customize the notification options available to users of the TCM application, see Example: Hiding or enabling a subscription option within the TCM application.
