Microsoft® SQL Server 2012 Unleashed

The Updating Subscribers Replication Model

SQL Server 2012 has built-in functionality that allows the subscriber to update data in a table to which it subscribes and have those updates automatically made back to the publisher through either immediate or queued updates. This model, called the updating subscribers model, utilizes a two-phase commit process to update the publishing server as the changes are made on the subscribing server. These updates are then replicated to any other subscribers, but not to the subscriber that made the update.

Immediate updating allows subscribers to update data only if the publisher will accept these updates immediately. If the changes are accepted at the publisher, they are propagated to the other subscribers. ...
