Alert Query

Hi all

Any idea why this Query used in Alert is not working in one database though there are results if we execute the Query manually in Query Generator?

No Alert message appear at all in one Company.  However it works in Demo Database.

SELECT T0.[CardName], count(DocNum) as 'DocCount', sum(T0.[DocTotal]) as 'Open PO Amount' FROM OPOR T0 WHERE T0.[CANCELED]  = 'N' and  T0.[DocStatus]  = 'O' GROUP BY T0.[CardName] ORDER BY T0.[CardName]
