Alert for Sales Order

Hi Experts

I need Query Based Alert for sales order .

when Sum of Quantity reaches  55500  when process equal to some X process in a particular month then it should pop an Alert

Ex:

SELECT SUM(T1.[Quantity]) FROM ORDR T0 INNER JOIN RDR1 T1 on T0.DocEntry = T1.DocEntry

WHERE T0.[U_Process] = 'PEACHING' and  T0.[DocDate] = (Select getdate()) AND  SUM(T1.[Quantity]) = '555000'

So please make changes for this query or write a new query please do needful

Regards

Jenny
