    Attribute Req Description Possible values

    Basic

    Sort key

    yes

    The key according to which records should be sorted. If they are sorted in any other way, the graph fails. For more information, see Sort Key.

    Details

    SequenceChecker receives data records through its single input port and checks their sort order. If this does not correspond to the specified Sort key, the graph fails. If the sort order corresponds to the specified Sort key, data records can optionally be sent to all connected output port(s).
