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.

To troubleshoot the issue, first I checked the msdb.dbo.sysmail_event_log table using the below query.

SELECT log_id, event_type, log_date, description, process_id, mailitem_id, account_id, last_mod_date, last_mod_user
FROM
msdb.dbo.sysmail_event_log 
ORDER BY
log_date DESC

If there is any error, you should see records with the event_type value as error.
In my case there are records with event_type value as error, and the description value for those records is same as below

The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 3 (2018-02-01T10:41:27). Exception Message: Cannot send mails to mail server. (The SMTP server requires a secure connection or the client was not authenticated. The server response was: Authentication required).  )

As per the error descript…

Get Period N data in MDX...

In some scenarios, we may need to get Period N data including the current period.
As an example if we select the Year as 2017, we may need to get the values for 2017, 2016, 2015, .., (2017-(n-1)).

I was able to achieve it using the below MDX Query

WITH
SET [Set_PeriodRange] AS
{STRTOMEMBER(@Param_Period+".lag(N-1))" : STRTOMEMBER(@Param_Period)}

SELECT NON EMPTY{[Measures].[Sales]} ON COLUMNS,
NON EMPTY([Set_PeriodRange]) ON ROWS 
FROM [SalesCube]

Here what I did was I created a set for the what ever the required period range, using the lag function.
Then use that Set for the Row axis in the MDX.
@Param_Period is the parameter with the Year value.

The use of the created Set is that if you pass the parameter value based on a hierarchy, it will return the members for the current level of the hierarchy.
If the current level is Quarter, it will return the N number of Quarters.

Hope this will be helpful...
