$DATA=>{'1234' => { 'open' => '1234-1',
               'analyzed' => '1234-2',
               'feedback' => '1234-3',
               'closed' => '1234-4'
             },
        '3455' => { 'open' => '3455-1',
               'analyzed' => '34552',
               'feedback' => '3455-3',
               'closed' => '3455-4'
              }
}

and am reading it in loop so pr will have 1234, 3455 etc.

Thanks for your help.

Thanks
