You *CAN* sort by aggregates
e.g.
select partno, status, sum(cmup) as cmup, sum(qty) as qty from my_table group by partno, status order by partno,
sum(cmup)desc;
partno | status | cmup | qty
--------+----------+------+----- test1 | incoming | 29 | 71 test1 | stock | 10 | 15 test2 | incoming | 12
| 10
