Previous YTD

Hi all

I am trying to perform Pervious Year To Date Total (which is like YTD but for the previous year. ie. ytd would work for this year's jan -> whatever month. But I need a total from Last year from jan -> whatever year to do comparision), However I've ran into the following issues.

Since Year is a variable and it can change depending on which year you select. I tried to Return the first member of the month which in theory should be January of a Year. However when I performed the below query I got Dec which was the overall period through out the entire Month this include 2002 dec -> 2005 May period so the head returned Dec.

SELECT { head(Descendants(
[Period].CurrentMember,
[Month]),1)} ON COLUMNS , { [BrandModel].[All BrandModel] } ON ROWS FROM [Running Report] WHERE ( [Measures].[Unit] )
So then I tried to return the Head of the Set of the current year using the below query. But no matter what I do I can not get it working.

SELECT { head(Descendants(
{[Period].CurrentMember, [Period].[Month]},
[Month]),1)} ON COLUMNS , { [BrandModel].[All BrandModel] } ON ROWS FROM [Running Report] WHERE ( [Measures].[Unit] )

How would you guys usually do a previous year to date comparision ? since year is a variable

Thanks

This isn't clear. Can you be more explicit?|||hi vector
