CDS EXTRACT DATE is the date (with an associated CDS EXTRACT TIME) of the update event (or the nearest equivalent) that resulted in the need to exchange this Commissioning Data Set.
CDS EXTRACT DATE is mandatory when used with the Commissioning Data Set Bulk Replacement Update Mechanism. It is not required when the Commissioning Data Set Net Change Update Mechanism is used, see the Commissioning Data Set Submission Protocol.
The CDS EXTRACT DATE (and CDS EXTRACT TIME if supplied) is used by the Secondary Uses Service to detect duplicate Interchanges of a similarly defined Bulk Update submission of Commissioning Data Sets.
The Secondary Uses Service processes and stores the date and time information to ensure correct updating of the Commissioning Data Set data in the correct relative date/time sequence.
