Charles,

Try the lateral key word before subquery. I just spent the morning
teaching about lateral correlation.

with list as (select line, ndcupc, gppc
from tempsav.cmw
left outer join medispan.mf2ndc on ndc = ndcupc )
select *
from list L
left outer join lateral (select ndcupc, idescr
, olsmlprg.calccustacqcost(decimal(150,6,0),
iitnbr) as acq_cost
, gppc
from medispan.mlitems M
left outer join
olsdta.ioritemmst using (iitnbr)
where gppc = m.gppc
order by 3
fetch first row only) as lowprc
on L.gppc = lowprc.gppc
