Hi,
There is no automatic email function to send change made in BOM. You have to create query, query layout and then you have to schedule and email to user.
Use below query:
SELECT T0.[Code], T0.[TreeType], T0.[UpdateDate], T1.[U_NAME] FROM OITT T0 INNER JOIN OUSR T1 ON T0.UserSign2 = T1.USERID WHERE datediff(dd, T0.[UpdateDate],getdate()) <=0
For scheduling and emailing refer below link:
Thanks & Regards,
