The date/time of the last updated to this record.

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 updated. 

''xxx'' represents the table alias - for example, P2K_DEN_BRU would be the trigger that fires when a record is updated on the DEN (P2K_CM_ENTITIES) table.
