SQL & PL/SQL :: Join Running Forever - Returns No Rows

select rl.org_rollup_skey from (select fc.org_skey as "FC_ORG_SKEY" from IA.HIST_FCT_FCST_SLS fc
inner join IA.DIM_ORG do
on fc.org_skey = do.org_skey
where do.org_nam IN ('101', '485','486')) p
INNER JOIN IA.DIM_ORG_HIER h
ON p.fc_org_skey = h.desc_org_skey
inner join IA.FCT_FCST_SLS_ORG_ROLLUP rl
on h.GPRNT_ORG_SKEY = rl.org_rollup_skey

Above join is taking is running forever even as subquery

(select fc.org_skey as "FC_ORG_SKEY" from IA.HIST_FCT_FCST_SLS fc
inner join IA.DIM_ORG do
on fc.org_skey = do.org_skey
where do.org_nam IN ('101', '485','486'))

returns no rows and this subquery give result in 10 seconds according to me Full query should not take more tha 20 secs.
