Basic MDX question

I understand the very basics of MDX. I know how to, for example, get
some set of measures as columns with some dimension on the Rows.
However, I need to do something more complex and I just can't get my
head around it.
What I'm trying to do is compare some given measure for various periods.
For example, say you have a measure [Sales] and a dimenion called
[Company Regions], the query to get the sales numbers for the company
regions basically looks like this:
with member [Date Dim].[Date Range] as
'Aggregate( {[Date Dim].[2004].[M05]:[Date Dim].[2004].[M06]}'
select [Measures].[Sales] ON COLUMNS,
Descendants([Company Regions], [Lowest Level], SELF_AND_BEFORE)
from myCube
where ([Date Dim].[Date Range])
That gives me the sales numbers for the months May and June.
What I need to do is that same basic query but I want to compare the
Date Range with last year. I just can't grasp how to make it show up in
the columns. I've read about cousin() and parallelperiods() but all the
examples return the period itself, not some measure in that period.
Can someone point me in the right direction?

Try it with a calculated member:
For example:
WITH MEMBER [Measures].[Sales_LastYear] as 'Sum([Date Dim].[2003],
[Measures].[Sales])'
MEMBER [Measures].[Sales_ThisYear] as 'Sum( {[Date Dim].[2004].[M05],[Date
Dim].[2004].[M06]}, [Measures].[Sales])'
MEMBER [Measures].[Sales_Difference] as ' [Measures].[Sales_ThisYear] -
[Measures].[Sales_LastYear]'
SELECT
{[Measures].[Sales_LastYear],[Measures].[Sales_ThisYear],[Measures].[Sales_D
ifference]} on COLUMNS,
Descendants([Company Regions], [Lowest Level], SELF_AND_BEFORE) on ROWS
from myCube

Basic Design Question Currency Dimension or New Measure

Hi All,
I am in the middle of a decision and I would like to ask experts for their
ideas.
I have Sales Reporting System on MSSQL 2000 + AS + RS
So far I have used only USD as reporting currency, now I am going to add
EURO and Local Currencies. My Current Model has "Sales", "Performance%" etc
as measures and Items,Countries etc as dimensions.
The question is how should I add new currencies to the system ?
As new Measures Sales_EURO?
or
As adding them to the fact table as rows keeping only one Sales measure and
adding a Currency dimension ?
I have around 2 million record in my fact table and data is accessed via
Reporting Services reports and via an application using OWC Pivot Table.
Thanks in advance?
erdalErdal,
Check out Adventure Works Enterprise Analysis services sample. I believe it
solves your problem via a currency dimension.

Unfortunately I dont have SSAS 2005 installed, think that sample comes with
SSAS 2005. Do you know is there any documentation for that project that I
can use without installing the application itself?
