Question

Date ordering causing problem when using lastchild.lag() function in MDX and SSAS 2008

Asked by: gosi75

I'm writing a query in MDX that shows the last 36 months on columns. I'm trying to use the lastchild.lag(0-35) for my members in order to get those data. What I'm now realizing is, that the members in the OLAP are not ordered timely, that is, instead of january 2003,february 2003, march 2003 they are in this order: january 2003, january 2004, january 2005 (see attached image).

What are my options here, I tried to change it in the SSAS but couldn't figure out how, and I'm not even sure if that is possible.
is that possible, or is there any other way to write the MDX to retrieve the last 36 months of data when the date dimension have this kind of ordering?

With 
MEMBER [Month1] AS 'SUM([Measures].[Amount],[Dates].[Month Name - Year].lastchild.lag(0))'
MEMBER [Month2] AS 'SUM([Measures].[Amount],[Dates].[Month Name - Year].lastchild.lag(1))'
MEMBER [Month3] AS 'SUM([Measures].[Amount],[Dates].[Month Name - Year].lastchild.lag(2))'
 
SELECT NON EMPTY 
{[Manufacturer].[Name]} ON ROWS,
{
[Month1],[Month2],[Month3]
} ON COLUMNS
 
FROM [Cube]
