You can use a replication definition to specify tables that have referential constraints, such as a foreign key and other check constraints, so that RTL is aware of these tables. See “RTL processing and limitations”.
Usually, the referencing table contains referential constraints for a referenced table within the same primary database. However, RTL extends referential constraints support to referenced tables from multiple primary databases. You can specify the referencing table in replication definition for each primary database. However, if multiple referential constraints conflict with each other, Replication Server randomly selects one referential constraint.
