A replication definition describes the source table to Replication Server, specifying the columns you want to copy.
It may also describe attributes of the destination table. Destination tables that match the specified characteristics can subscribe to the replication definition.
Replication Server provides replication at the database, table, and stored procedure levels. RM allows you to create a replication definition for a database, a table, or a stored procedure. A replication definition for a stored procedure is called a “function replication definition”. You can create, edit, and delete function replication definitions and function subscriptions.
