MDXQuery - Currentmember with his parent - mdx

Question

I'm trying to write a MDX query that would display all my products and the subgroups (hierarchy parent) that they belong to. While the task seems rather trivial i still can't figure it out. Here is my MDX query.
select
{
[Products].[Hierarchy].currentmember.parent
}
on 0,
{
[Products].[Hierarchy].[Product].members
}
on 1
from [CUBE]
I also tried
select
{
Ancestor([Products].[Hierarchy].currentmember,
[Products].[Hierarchy].[Subgroup])
}
on 0,
{
[Products].[Hierarchy].[Product].members
}
on 1
from [CUBE];
But all I get from it is a gray list of products without any actual column. Any help/tips would be greatly appreciated.

Answer 1

If you want to use the same hierarchy then you can only use it on one axis - there are 3 axis in context - ON COLUMNS / ON ROWS / WHERE.
So putting [Products].[Hierarchy]. ON COLUMNS and also ON ROWS would throw an exception.
What you can do is move some of the logic into a WITH clause and move the narrative into the Measures dimension:
WITH
MEMBER [Measures].[ProdName] AS
Ancestor(
[Products].[Hierarchy].currentmember,
[Products].[Hierarchy].[Subgroup]
).MEMBER_CAPTION
SELECT
[Measures].[ProdName] ON 0,
[Products].[Hierarchy].[Product].MEMBERS ON 1
FROM [CUBE];
You could make use of your attribute hierarchies and do something like this:
SELECT
{} ON 0,
[Products].[Product].[Product]
*[Products].[Subgroup].[Subgroup]
ON 1
FROM [CUBE];
