Email Alerts are not received...

In one of application, Email alerts are sent using SQL sp_send_dbmail stored procedure. Email alerts were working properly, but suddenly noticed email alerts are not received.

msdb.dbo.sysmail_event_log 
ORDER BY
log_date DESC

As I explained in my previous post, we need to maintain a mapping table for this requirement as well. Lets assume the name of the mapping table is SECURITY_MANAGER_REGION and the columns will be SalesManagerId, RegionId and MonthId. In this scenario I assumed sales manager is assigned for a particular region, at least for a period of Month.

Then we need to have the SECURITY_MANAGER_REGION table data in a fact table and can grant the access for the Region and Month dimensions based on it with in the same role.

But the issue is since those…
