The State indicates whether the object already exists in this adTempus instance:

When an object has a state of Duplicate, this indicates that an object with the same primary key but a different OID already exists. For example, if a NotificationIndividual is marked Duplicate, a NotificationIndividual already exists with the same name but a different OID. When duplicate objects are imported, adTempus updates the existing object with the data from the import source rather than importing the duplicate object. The existing object's OID does not change.
