A BAR component is an entity or defined relationship, such as a media server configuration, that is associated with a Teradata DSA job. A BAR component cannot be deleted from the Teradata DSA configuration if it is specified in a job, regardless of whether the job is in an active or retired state. Generally, in order for a component to be deleted, any job that references the component must be deleted first. There is one exception: If the only reference to the BAR component is in a new job that has never been run, the component can be deleted.
