Why subqueries in case are not working in teradata? - response (8) by AshishPatil

Hi Dieter,
 
 As you said the syntax should work on TD 13.00, but same is not working on 13.10. Can you pls suggest some changes to achieve same on TD.
Below is my complete query,
 

select distinct a.asset_wid,a.PR_VIS_ORG_WID,a.SELL_DT_WID,a.prod_wid,a.contact_wid,a.accnt_wid,

case 

when 

(a.contact_wid <> 0 and W_PARTY_PER_D.x_district is not null ) then

 (case when W_PARTY_PER_D.X_DISTRICT in (select upper(WC_ORG_EXT_XM_F.attrib_04) from wc_org_ext_xm_f where pf_org_wid = a.PR_VIS_ORG_WID) 

 then 0 else 1 end )

else 

(case when W_PARTY_ORG_D.X_DISTRICT in (select upper(WC_ORG_EXT_XM_F.attrib_04) from wc_org_ext_xm_f where pf_org_wid = a.PR_VIS_ORG_WID)

 then 0 else 1 end ) 

 end infringement

from (

SELECT 

W_ASSET_D.ROW_WID asset_wid, 

W_ASSET_F.PR_VIS_ORG_WID PR_VIS_ORG_WID, 

W_ASSET_F.SELL_DT_WID SELL_DT_WID,

W_ASSET_F.SELL_DT_WID) a ,
