DB2 query with multiple WITH AS cases not compiling

For some reason, I can’t get this query to perform as I’m getting an error:

Token ( was not valid. Valid tokens: , FROM INTO.

I’m running this in DB2 and I think this is occurring at either the very first line of the 2nd with/as at ) , A AS ( SELECT

Where am I going wrong?

WITH
  RES (PRODUCT_ID, JOB_STATUS, JOB_STATUS_TIME) AS
(
select
    T1.NAME,
    t2.PRODUCT_id as PRODUCT_ID,
    t3.product_id,
    t3.created_at,
    t5.name as JOB_STATUS,
    t4.row_created_timestamp as JOB_STATUS_TIME ,
    t3.expiration_timestamp
from schema.PRODUCT T1
inner join schema.PRODUCT_to_product T2
on t1.PRODUCT_id = t2.PRODUCT_id
inner join schema.product t3
on t2.product_id = t3.product_id
inner join schema.product_to_job_statust t4
on t3.product_id = t4.product_id

    and t3.created_at >= '2019-09-20'
    and t5.name <> 'D'
order by t1.name,t3.product_id

SELECT
  PRODUCT_ID, JOB_STATUS

, LEAD (JOB_STATUS_TIME) OVER (PARTITION BY PRODUCT_ID ORDER BY JOB_STATUS_TIME) AS JOB_STATUS_TIME_NEXT
FROM RES
)
SELECT

It is always a good idea to use an SQL Editor that supports the version of Db2 that you are using.

Looking at your SQL in IBM Data Studio with the validation set to DB2 for i 7.2, highlights the following line in red underscores

, LEAD (JOB_STATUS_TIME) OVER (PARTITION BY PRODUCT_ID ORDER BY JOB_STATUS_TIME) AS JOB_STATUS_TIME_NEXT`

Cross referencing to the manual, I can see that LEAD is supported in Db2 for i 7.3 but not Db2 for i 7.2

So that would be my guess at your syntax error
