Hi Mimi
There is no standard price alert in SAP B1.You can achieve this through a query .
below query can help you
Select DocEntry,DocNum FROM ADOC A Inner join ORDR B ON A.DocEntry = B.DocEntry
Copy this Query and execute and save in query manager .Now go to Alert management and select this query and give time line for every 10 min or 15 mins so that when a price is changed you can see for every 10 mins .
Regards
Jenny
