Understanding External Search/Match Integration

In an integrated, separate-instance environment using the distinct ownership model, users who want to maintain a single EmplID must use External Search/Match in each system to ensure the creation of unique person records. Initially, users use positive External Search/Match results to locate and add person data from the external system (such as a CS user searching against HCM); subsequently, person updates must be done manually in both instances to avoid becoming out of sync.

In the distinct ownership integration model, External Search/Match is the tool used to ensure that only unique EmplIDs are added to any system. With distinct ownership, people are added in either the CS or HCM system (as appropriate); both systems use External Search/Match to search for possible duplicate records so only unique IDs are shared between the databases. However, both databases must be running in order for External Search/Match to work.
