The Control Center creates and populates the replication control tables through SQL files. You can customize these files outside of the Control Center before using the Control Center for replication administration. Most customers need to customize the replication control tables for their site.
The Control Center also creates and populates the replication target tables using SQL generated by replication requests, such as defining a replication source. You can store the SQL in a file and then edit and run it later. Most customers need to customize the control information for replication sources and subscriptions.
See "Working with Customized Replication Control Tables" and "Customizing and Running Replication SQL Files" to learn how to customize SQL files for your site.
