Please explain how there may be multiple 8000 CCNs ‘cancelling’ one Primary CCN?

In a Buyer’s Consolidation there may well be multiple eHBL 8000 CCNs, all destined to the same importer.  The Close Message transmitted by the freight forwarder links all of those 8000 CCNs to the ‘Previous’ Cargo Control Number, which in this example would be the same as the carrier’s Primary Cargo Control Number in each eHBL 8000 transmission.  Thus, the primary carrier’s CCN is ‘cancelled’ by the 8000 CCNs.  All of the 8000 CCNs can be attached to one Customs release request.
