How to: Set the Expiration Period for Subscriptions (Replication Transact-SQL Programming)

The expiration period for subscriptions, also known as the retention period, determines the period of time before a subscription expires and is removed. For more information, see Subscription Expiration and Deactivation. You can use replication stored procedures to either set this value when a publication is created or modify this value at a later time.
