You might need to add the MemberDataRecords into WM and use not exists
 
when
    $d : Data()
    $mdr : MemberDataRecord( $d1 : loggedInDate )
    not exists MemberDataRecord ( loggedInDate > $d1 )
then
    //Smurf
end

yeah.........i did the same with following code
 
//////////////

$d : Data($memDataRecods :memberDataRecords )

$mdr : MemberDataRecord($loggedindate:logged_in_date )from $memDataRecods not MemberDataRecord( logged_in_date < $loggedindate )

//////////

when what happened was it iterates over earch memDataRecods in decending order........

what i need is to get only the very first record...........
