Hi,
Possible by means of standard alert. Please follow below steps.
1. Run and save below query in query manager
SELECT T0.[DocNum], T0.[CardCode], T1.[ItemCode], T1.[Price], T2.[AvgPrice] FROM OPOR T0 INNER JOIN POR1 T1 ON T0.DocEntry = T1.DocEntry INNER JOIN OITM T2 ON T1.ItemCode = T2.ItemCode WHERE T1.[Price] <> T2.[AvgPrice] and T0.[DocDate] = CONVERT(VARCHAR(10),GETDATE(),110) GROUP BY T0.[DocNum], T0.[CardCode], T1.[ItemCode], T1.[Price], T2.[AvgPrice]
2. In alert management, assign above query to user to notify.
Thanks & Regards,
