RE: SQL CTE with union and group by

Have you tried each part of the CTE and the individual SQL statements used in the UNION? I always debug my SQL statements--especially complex ones like yours this way first.
If that works, it could be in the use or non-use of the column in GROUP BY clauses.

I do the debugging using the "Run SQL Scripts" function of ACS--although anything with similar functionality should work.

If there's no problem with the individual pieces, it'll take a little more digging. I had to open a PMR several years ago for a similar error. IBM found the bug and issued a PTF for it.

Maybe if you explicitly qualify all of your selected cte_t1 columns in the
definition of cte_t2 with a prefixed "t." could work, as you aliased
icte_t1 t as "t".

I am trying to do the following SQL CTE.
I get an error
SQL State: 42703
Vendor Code: -206
Message: [SQL0206] Column or global variable T1FEEINV not found. Cause .

.

. . . : T1FEEINV was not found as a column of table *N in *N and was not
found as a global variable in *N. If the table is *N, T1FEEINV is not
a column of any table or view that can be referenced, or T1FEEINV is a
special register that cannot be set in an atomic compound statement.

I feel like my as t1feeinv is defining it. What am I missing?

with cte_t1 as (
select po.clientnam as t1clientnam
,po.divnam as t1divnam

,case when po.ltrtypdes = 'General Rights' then count(po.ltrtypdes)
else 00
end as t1poct
,00 as t1qbct
,00 as t1spmct
,case when po.ltrtypdes = 'Rights Notice' then count(po.ltrtypdes)
else 00
