Group by months in a time hierarchy using MDX - mdx

Question

I have a dimension with the following levels:
Years
Months
Days
I want to get some data by months regardless of the year, i.e. weddings in January.
If I have:
January 2011 - 43
January 2012 - 20
January 2013 - 30
What I want is:
January - 93
Is it possible?
Thanks
Edit:
I have tried this query (with sales, no weddings):
WITH member [Time].[example] AS 'AGGREGATE({[Time].[Months].[Jan]})'
SELECT
NON EMPTY {Hierarchize({[Measures].[Sales]})} ON COLUMNS,
NON EMPTY {[Time].[example]} ON ROWS
FROM [SteelWheelsSales]
but I only get the first January.

Answer 1

Yes, this depends on how you structured your calendar dimension. In this case, you would have a month string field, and it would have
January
February
... So on... Note that the month string field, does not have the year included.
This field would be aggregatable set in the SSAS dimension. When creating your MDX query you would put month on rows, and weddings on columns. Using this approach you should get your desired result.
So doing the following should get you all January sales :
SELECT
NON EMPTY {[Measures].[Sales]} ON COLUMNS,
NON EMPTY {[Time].[Year] * [Time].[Jan]} ON ROWS
FROM [SteelWheelsSales]
