I think you need to join the table back on itself to get the total
for each part. Not a very impressive incantation, but I'd do it
in SQL like this:

SELECT x.partno, x.status, y.tot, sum(x.qty)
FROM my_table x, (
SELECT partno, MAX(cmup) as tot
FROM my_table
GROUP BY partno) y
WHERE x.partno = y.partno
GROUP BY x.partno, x.status, y.tot
