After looking at the query I can see that the function is taking a lot of time to execute the below query.I am also sending you the explain plan of the above query

Your TKPROF is showing that every step of the plan is picking up 0 rows, but still 122,181 buffers have been retrieved from the row cache. Are all of the tables empty?
If so, did any of the table PREVIOUSLY contain many rows that have now been deleted. This empty space left behind can affect queries. Search HWM for more on this.
Alternatively, your full table scans could be scanning many rows and then your filter criteria could be filtering out every row.
We need to know how many rows are in each table.

Dear Sir
Well let me tell you that in the query there is a view in the query by the name
c3vw_ckr_trndisbchklst2_rpt.This query is taking 6.625 seconds to execute it
select distinct
tdc2.BASE_ENTITY_ID, tdc2.PROCESS_ID, tdc2.SUB_PROCESS_ID,
tfg.id as tfg_id,
replace(fn_getfacgrpfacdtls(tfg.id), '<br/>', chr(13)) as fac_detail ,
tdc2.PARTICULARS ,
yn_rec.yesnona as recd,
yn_sv.yesnona as sv,
replace(fngetdate(tdc2.DEFERRAL_IN_PLACE), '01/01/1235', '') as diffral,
decode(da.id, 0, ' ', da.deferral_auth) AS diff_auth,
yna_seal.yesnona as seal ,
yna_stmpduty.yesnona as stmpduty,
yna_stmpppr.yesnona as stmpppr,
replace(tdc2.REMARKS, '~', '') as remarks,
tdr.mst_doc_id,
tdr.mst_doc_catg_id
from trn_disb_chk2 tdc2, mst_yesnona yn_rec, mst_yesnona yn_sv, mst_deferral_auth da, mst_yesnona yna_seal, mst_yesnona yna_stmpduty, mst_yesnona yna_stmpppr,
trn_disb_chk1 tdc1, trn_c3_fac_group tfg, trn_doc_reg tdr
where tdc2.received = yn_rec.id and
tdc2.sv_done = yn_sv.id and
tdc2.deferral_authority_id = da.id and
tdc2.common_seal_affixed = yna_seal.id and
tdc2.stmp_ppr_lt_6mth = yna_stmpppr.id and
tdc2.corrt_stmp_duty_pd = yna_stmpduty.id and
tdc2.trn_disb_chk1_id = tdc1.id and
tdc1.trn_c3_fac_group_id = tfg.id and
tdr.mst_doc_id = tdc2.trn_doc_reg_id
order by tdc2.base_entity_id, tdc2.sub_process_id, tfg.id, tdr.mst_doc_catg_id, tdr.mst_doc_id
To execute this view it is taking 6.625 seconds to execute it
In the umstusers there are 226 rows
in the aud_proc_trn_state 20245 rows
In the trn_proc_state there are 552 rows
The above view as well as the function by the name
FN_C3_GETLASTCKRDT_WKF(tps.base_entity_id, tps.trn_cam_id, tps.trn_c3_fac_group_id, tps.mstwf_process_item_id) >= tps.trans_datetime
in the query is killing the performance
Can you please help me to optimise the view as well as the function to increase the performance,
Regards

Sorry, your query is too complex, and I have too little spare time.
If your function contains SQL, then you need to work out a different way to run this without using the function. See this article - http://www.orafaq.com/node/1981
If your view contains DISTINCT, GROUP BY, or other complexities, it may affect Oracle's ability to optimise the overall query. You could try writing the query from first principals without the view.
