BigQuery | How to select * from previously defined CTE in the same query? - sql

Question

I have the below SQL query which I want to run on BigQuery.
I am constantly getting error : Unrecognized name: nojoin on the start of the select statement of CTE named onejoin.
Please help. It works for uom_conversion.* in nojoin CTE but nojoin.* doesnt work in onejoin CTE.
WITH uom_conversion AS
(
select a.*,
case when a.sales_unit in ('EA','ZIN') and b.unit = 'CSE' then ifnull(a.order_quan*b.bic_zconvfac,0.0) else a.order_quan end as cse_order_quan,
from `dev-amea-analyt-datal-svc-db.dev_amea_h_sapbw_ptc_otc.v_sales_order_items_amea` as a
left join `dev-amea-analyt-datal-svc-db.dev_amea_h_sapbw_mst.v_mat_unit_otc_amea` as b
on a.material = b.material and a.sales_unit = b.bic_zaltunit
),
nojoin AS
(
SELECT uom_conversion.*,
case when unit_of_wt = 'KG' and doc_type = 'ZOR' then net_wgt_dl end as ship_ord_kg_mysg_osa
from uom_conversion
),
onejoin AS
(
SELECT nojoin.*,
case when orders.doc_type = 'ZOR' and orders.reason_rej = '0' and delivs.biczdelv_itm = '0' and orders.unit_of_wt = 'KG' then orders.net_wgt_dl end as ship_ooqty_kg_mysg_osa
from nojoin as orders
left join `dev-amea-analyt-datal-svc-db.dev_amea_r_sapbw_ap_ptc_otc.v_sales_delivery_items_ap` delivs
on orders.doc_number = delivs.doc_number
),
twojoins AS

SELECT onejoin.*

from onejoin as orders
left join `dev-amea-analyt-datal-svc-db.dev_amea_r_sapbw_ap_ptc_otc.v_sales_delivery_items_ap` as delivs
