I don't think I understand the idea behind this query. Do you really need
billing_reports twice?

Maybe this is the query you want instead?

select w.appid,
       w.rate,
       w.is_subscribed,
       sum(w.hits) AS Hits,
       sum(w.sius) AS IUs,
       sum(w.total_amnt) AS Total,
       sum(w.hits) * w.rate AS ByHits,
       sum(w.sius) * w.rate AS BYIUS
  from bill_rpt_work w
 where w.report_id in
       (select b.report_id from billing_reports b where b.report_s_date =
'2006-09-30')
   and (w.client_id = '227400001' or w.client_id = '2274000010')
group by 1,2,3
order by 1,2,3;
