How to implement "greater than" based on dimension value in MDX - ssas

Question

I would like to query the total sales of each country with the GDP growth rate of more than 3. So far, I can display the sales information of each country like such:
SELECT
{[Measures].[Sales]} ON 0,
{[Dim Company Info].[LOC].ALLMEMBERS} ON 1
FROM [Database]
But then I am still blank on how to query all GDP growth rate of more than 3. I have searched SO and found filter to be the answer, however, I do not know where to include it in my code above. How do I go about this?
Edit: I have tried the followings, but I do not think that is what I am supposed to do:
WHERE ([Dim Company Info].[Gdp Growth].&[3] : [Dim Company Info].[Gdp Growth].&[3].LastChild)
and
SELECT
{[Measures].[SALES]} ON 0,
{FILTER([Dim Company Info].[LOC].MEMBERS, [Dim Company Info].[Gdp Growth] > 3)} ON 1
FROM [766 Database]
and
SELECT
{[Measures].[SALES]} ON COLUMNS,
{[Dim Company Info].[LOC].MEMBERS} ON ROWS
FROM [766 Database]
WHERE FILTER([Dim Company Info].[Gdp Growth], [Dim Company Info].[Gdp Growth] > 2)

Answer 1

You can use your below expression when the dimension members are numericly arranged
WHERE ([Dim Company Info].[Gdp Growth].&3 : [Dim Company Info].[Gdp
Growth].&3.LastChild)
with a slight correction
WHERE ([Dim Company Info].[Gdp Growth].&[3] : [Dim Company Info].[Gdp Growth].[Gdp Growth].LastChild)
However if that is not the case, then you need to follow the below method.
I am reporting the product with the max quantity.
select {[Measures].[Internet Sales Amount]} on 0,
non empty
([Product].[Product].[Product],[Promotion].[Max Quantity].[Max Quantity]) on 1
from [Adventure Works]
Now lets manipulate the max quantity to make it behave like a measure.
with
member measures.test
as
case when [Measures].[Internet Sales Amount]>0 then
(nonempty(([Product].[Product].currentmember,[Promotion].[Max Quantity].[Max Quantity]),[Measures].[Internet Sales Amount])).item(0).item(1).name
else
null end
select
{[Measures].[Internet Sales Amount],measures.test}
on 0,
non empty ([Product].[Product].[Product] )
on 1
from [Adventure Works]
Now you can use the filter, but we need to cast(note the use of CInt) the data too
with
member measures.test
as
case when [Measures].[Internet Sales Amount]>0 then
Cint((nonempty(([Product].[Product].currentmember,[Promotion].[Max Quantity].[Max Quantity]),[Measures].[Internet Sales Amount])).item(0).item(1).name)
else
null end
select
{[Measures].[Internet Sales Amount],measures.test}
on 0,
non empty (
filter(
[Product].[Product].[Product]
,measures.test>0)
)
on 1
