Adding or dropping database replication definitions does not affect table or function subscriptions.
When you alter a database replication definition, you replace the database replication filter. Replication Server places a marker in the inbound queue and allows the DIST to process the command. The new filter is applied to transactions committed after the marker.
If a table subscriptions exists, no action is required.
If no table subscription exists, you must include the dsi_suspended clause in the alter database replication definition command, or manually materialize or dematerialize the table.
