How to use use the Person.UID_PersonMasterIdentity column?

Hello, everyone,

          I have a question about how to use the Person.UID_PersonMasterIdentity column.

           The information I found is: “The column Person.UID_PersonMasterIdentity is only shown if an employee has several identities to manage.” (Source:

https://support.oneidentity.com/technical-documents/identity-manager/8.0.1/configuration-guide/81#TOPIC-909964). This is a default column that comes with the software.

          To my understanding, if a person has several management accounts, his UID will be in the column of Person.UID_PersonMasterIdentity in all the accounts.

          Is this the right way to use the Person.UID_PersonMasterIdentity column? Do you have any new idea?

          Thank you.
