Property Value

An Int32 value that specifies the number of hours before the subscription expires if the subscription is not yet synchronized with the publication.

The RetentionPeriod property can only be retrieved by members of the sysadmin fixed server role at the Publisher, by members of the db_owner fixed database role on the publication database, or by users in the publication access list (PAL).

The RetentionPeriod property can only be set by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database. Users in the PAL can set the RetentionPeriod property of an existing publication.

Setting the RetentionPeriod property is equivalent to executing sp_addpublication (Transact-SQL) and sp_changepublication (Transact-SQL) or sp_addmergepublication (Transact-SQL) and sp_changemergepublication (Transact-SQL).
