It's because column alias is in the wrong place. It should probably be:
(SELECT SUM(BUDGET.AMOUNT_COMMITED) FROM MCA.BUDGET) AS COMMITED
BUT ... I'm not sure why it's a subquery. I was expecting something more like
SELECT BUDGET.JONO, BUDGET.FY, SUM(BUDGET.AMOUNT_COMMITED) AS COMMITED
FROM MCA.BUDGET
GROUP BY BUDGET.JONO, BUDGET.FY
