Kindly help with rewriting the foll. query in a better way

Question

IS there a better way of writing the foll query:
When I have 12,50,00,000 rows in Fact Table, the query is unable to execute. I use more than 200GB of temporary space. But I still get Temp Tablespace Full Error:

Answer 1

Thanks for the response Alfonso. I have tried that as well. But Create Table as Also uses Temp Storage till it's created. And that again gives the same error as well.
Anyways I am now trying with a smaller set. This much piece gets executed in Half an hour but the next piece where we pivot the data is taking forever now.
That piece is as follows:
(SELECT /*+parallel(8)*/
f.hrarchy_dmn_id,
f.prduct_dmn_id,
f.crncy_dmn_id,
f.acnt_dmn_id,
f.txn_id,
f.txn_src,
f.acntng_entry_typ,
f.val_dt_dmn_id,
f.revsn_dt,
SUM (
blnc)
OVER (
PARTITION BY f.hrarchy_dmn_id,
f.prduct_dmn_id,
f.crncy_dmn_id,
f.acnt_dmn_id,
f.txn_id,
f.txn_src,
f.acntng_entry_typ
ORDER BY d.date_value)
AS crnt_blnc,
SUM (
blnc)
OVER (
PARTITION BY f.hrarchy_dmn_id,
f.prduct_dmn_id,
f.crncy_dmn_id,
f.acnt_dmn_id,
f.txn_id,
f.txn_src,
f.acntng_entry_typ,
d.fin_mnth_num
|| d.fin_year_strt
|| d.fin_year_end
ORDER BY d.date_value)
/ d.mnth_to_dt
AS mtd_avg,
SUM (
blnc)
OVER (
PARTITION BY f.hrarchy_dmn_id,
f.prduct_dmn_id,
f.crncy_dmn_id,
f.acnt_dmn_id,
f.txn_id,
f.txn_src,
f.acntng_entry_typ,
d.fin_year_strt || d.fin_year_end
ORDER BY d.date_value)
/ yr_to_dt
AS ytd_avg,
f.prvs_rcrd_ind AS prvs_rcrd_ind
FROM cmbnd_rcrds f, thor_date_dmn d
WHERE d.holidaY_ind = 0 AND f.val_dt_dmn_id = d.date_dmn_id)
SELECT f.hrarchy_dmn_id,
f.prduct_dmn_id,
f.crncy_dmn_id,
f.acnt_dmn_id,
f.txn_id AS txn_id,
f.txn_src AS acntng_entry_src,
f.acntng_entry_typ AS acntng_entry_typ,
f.val_dt_dmn_id,
f.revsn_dt,
f.crnt_blnc,
f.mtd_avg,
f.ytd_avg,
'EOD TB ETL' AS crtd_by,
SYSTIMESTAMP AS crtn_dt,
NULL AS mdfd_by,
NULL AS mdfctn_dt
FROM fnl_set f
WHERE f.prvs_rcrd_ind = 0
ORDER BY f.hrarchy_dmn_id,
f.prduct_dmn_id,
f.crncy_dmn_id,
f.acnt_dmn_id,
f.txn_id,
f.txn_src,
f.acntng_entry_typ,
f.val_dt_dmn_id
Any other way to pivot this?
Also I am getting a lot of foll wait events:
PX Deq Credit :Send blkd
PX Deq :Table Q Normal
Direct Path Write Temp
And Direct Path Read Temp.
