    Clustered

    More information:

    Virtual Primary Key

    Only for SAP NetWeaver BI systems with BW Feature Pack

    For tables which have no primary key, the system forms a primary key internally and sets the Clustered attribute. Columns which the system uses for the primary key do not need to have the UNIQUE attribute.

    Packed

    Only for SAP NetWeaver BI systems with BW Feature Pack

    The system stores numerical columns that are not key columns in compressed form.
