I'm trying to mark records for deletion based on an aggregate total within the same table?       If an aggregate grouping with the tblVesselMessageBunkerConsumption  is zero then I want to mark those rows for deletion  but not the ones that total greater then zero. Where am I going wrong because no matter what I do they end up all being marked?

            UPDATE c
               SET c.IsActive = 0,
                     c.IsDelete = 1
            FROM
             tblVesselMessage a
             JOIN tblVesselMessageBunkerConsumption c ON a.VesselMessageID = c.VesselMessageID
            CROSS APPLY (SELECT VesselMessageID,
                               UsageUserDictionaryID,
                               EngineUserDictionaryID,
                               isSlr,
                               RowDisplayOrder,
                               Quantity=SUM(ISNULL(Quantity,0)) ,
                               IsActive,
                               IsDelete
                         FROM tblVesselMessageBunkerConsumption
                          WHERE VesselMessageID = c.VesselMessageID
                           GROUP BY  VesselMessageID,
                                           UsageUserDictionaryID,
                                           EngineUserDictionaryID,
                                           isSlr,
                                           RowDisplayOrder,
                                           Quantity,
                                           IsActive,
                                           IsDelete )  b
       
            WHERE
                   a.EVFAcctID = 2
                   AND b.isActive = 1
                   AND b.isDelete = 0
                   AND b.RowDisplayOrder IS NOT NULL
                   AND b.Quantity = 0
                   AND c.isActive = 1
                   AND c.isDelete = 0
                   AND c.RowDisplayOrder IS NOT NULL
                   AND c.VesselMessageID = 15196
