select part_no,
sum(cast when trans_type='REC' then trans_qty else 0) as
"on_hand",
sum(cast when trans_type='ALL' then trans_qty else 0) as
"allocated",
sum(cast when trans_type='SHP' then trans_qty else 0) as
"allocated"
from inventory_transaction_table
group by part_no;
except, your example output doesn't correlate with your sample input
according to any rules I can see.
