In a replication
      system containing only Adaptive Server databases, you can reduce the need for replication
      definitions and subscriptions for tables and stored procedures in a warm standby or multisite
      availability (MSA) environment. 
You need not
         create a replication definition for a primary table or stored procedure if the sole purpose
         of the replication definition is to specify some or all of the
            following:
- Primary key columns
 
- Table or column names that may be quoted. 
 
- Customized function strings for replicate tables or stored procedures.
