Later on, you may add new tables and user stored procedures that you want to replicate to the new standby database.
If you marked the standby database for replication with sp_reptostandby, any new tables are automatically marked for replication.
If you marked individual database tables for replication to the new standby database with sp_setreplicate, you must mark each new table that you want to replicate with sp_setreplicate.
You must mark each new user stored procedure that you want to replicate with sp_setrepproc.
