The data base user who originally created this record. If the change is made through self service, the CHANGE_USER field will be the PERSON_CODE (if through Employee/Manager Self Service) or the CANDIDATE_CODE (if through Candidate Self Service).
This field is maintained by the data base trigger P2K_xxx_BRI, a before-insert data base trigger that automatically fires when a record is being created for the first time.
xxx represents the table alias - for example, P2K_DEN_BRI would be the trigger that fires when a record is inserted on the DEN (P2K_CM_ENTITIES) table.
