Remarks
sp_expired_subscription_cleanup is used in all types of replication.
The Expired Subscription Clean Up job runs sp_expired_subscription_cleanup to detect and remove expired subscriptions from publication databases every 24 hours. If any of the subscriptions are out-of-date, that is, aren't synchronized with the Publisher within the retention period, the publication is declared expired, and the traces of the subscription are cleaned up at the Publisher. For more information, see Subscription Expiration and Deactivation.
