синтаксическая ошибка: помогите найти ее во временной таблице

Question

Я пытаюсь преобразовать следующий сценарий Teradata в BigQuery:

drop table NK1_120golive_vol;
create volatile table  NK1_120golive_vol
(    ktnr bigint,
     dex smallint)
on commit preserve rows;

insert into NK1_120golive_vol
sel a.ktnr, case when Nachfragemenge > 0 and (Nachfragemenge - Stornomenge) > 0  then 1 
                            when (Nachfragemenge > 0 and (Nachfragemenge - Stornomenge) = 0)  then 100
                            
else 99 end dex
from (sel BPID, BPTypeID from  VAT.AddressOverview where FirmID =11 ) as a (ktnr, Partnerart)
left join (sel BPID, sum(case when Rectype in(1) then KPIValueQty else 0 end) , 
sum(case when Rectype in (3,121) then KPIValueQty else 0 end)                                 
from VAT.positions where (Reportingdate-OrderAge) between 1200101 and 1200630  group by 1 ) as kred (ktnr, Nachfragemenge, Stornomenge) on a.ktnr = kred.ktnr    
left join vat.CustomerOverview c on a.ktnr = c.BPID
left join scat.cust120_au_alle_dexe e on a.ktnr = e.BPID
where Partnerart like 'Z001' and e.BPID is null  or Partnerart like 'Z001' and e.dex between 14 and 100 and Nachfragemenge > 0 
group by 1,2; 

Вот мой перевод BigQuery:

create or replace temp table NK1_120golive_vol as ( 
                 with a as( select bpid as ktnr, 
                    BPTypeID as Partnerart
                    from VAT.AddressOverview where FirmID =11),
                    b as( select bpid as ktnr,
                    sum(case when Rectype in(1) then KPIValueQty else 0 end) as Nachfragemenge,
                    sum(case when Rectype in (3,121) then KPIValueQty else 0 end) as Stornomenge
                 from VAT.positions ) ,
                c as (select bpid, BPTypeID from vat.customeroverview) ,
                e as ( select bpid, dex from scat.cust120_au_alle_dexe),
                
            tmp10 as (select a.ktnr, case when Nachfragemenge > 0 and (Nachfragemenge - Stornomenge) > 0  then 1 
                                                     when (Nachfragemenge > 0 and (Nachfragemenge - Stornomenge) = 0)  then 100
                                                     else 99 end dex
                                                     from a 
                                                     left join c on a.ktnr =c.bpid
                                                     left join e on a.ktnr = e.bpid
                                                     where Partnerart like 'Z001' and e.BPID is null  or Partnerart like 'Z001' and e.dex between 14 and 100
                                                     and sum(case when Rectype in(1) then KPIValueQty else 0 end) >0))
                           
                           
                            select * from NK1_120golive_vol

Но я получаю следующую ошибку:

Синтаксическая ошибка: ожидалось "(" или "," или ключевое слово SELECT, но получено ")" в [20: 170]

Что я делаю не так?
