A Replication Server subscription is a request for Replication Server to maintain a replicated copy of objects (such as a tables, stored procedures, databases, or publications) in a replicate database at a specified location. You can create subscriptions for function replication definitions for replicating stored procedures.
Subscriptions resemble SQL select statements and identify the replication definition or publication to which you are subscribing, the source and destination databases and data servers, and the materialization method by which the initial information is to be copied. Create subscriptions at the Replication Server that manages the database where the replicate data is to be maintained.
