The data base user who last updated this record.  Note that if the record is created through self-service, the data base user will be the [schema] owner P2K.

This field is maintained by the data base trigger P2K_''xxx''_BRU, a before-update [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_BRU would be the trigger that firs when a record is updated on the DEN (P2K_CM_ENTITIES) table.
