MDX calculated dimension attribute

Question

Is it possible to create a query scoped dimension attribute (as is done with measures) using the WITH statement.

I'm trying to do something like this:

WITH
MEMBER [Customer].[Has Child At Home] AS
IIF( [Customer].[Number of Cars Owned] > 0,
True,
False

)

And then use the above attribute in a select statement however it is giving me an error saying that the customer dimension has more than one hierarchy and that one needs to be specified.

Answer 1

In this format it requires a hierarchy, to build on your code example [Number of Cars Owned] would need to be a hierarchy:

WITH
  MEMBER [Customer].[Number of Cars Owned].[Has Child At Home] AS
  IIF([Customer].[Number of Cars Owned] > 0, "True", "False")
SELECT
  {[Customer].[Has Child at Home]} ON COLUMNS,
  [DimExample].[AttributeExample].Members ON ROWS,
FROM [CubeExample]
