Using WITH in mdx to retrieve row names - mdx

Question

I am executing the following MDX query in SSMS, which I have got from Profiler:
SELECT {
[Measures].[Dollar Amount],
[Measures].[Transaction Count]}
DIMENSION PROPERTIES PARENT_UNIQUE_NAME,HIERARCHY_UNIQUE_NAME ON COLUMNS,
NON EMPTY Hierarchize({DrilldownLevel({[Retail Sales Date].[Month].[All]},,,INCLUDE_CALC_MEMBERS)})
DIMENSION PROPERTIES PARENT_UNIQUE_NAME,HIERARCHY_UNIQUE_NAME ON ROWS
FROM [Retail Sales Cube]
WHERE ([Geography].[Retail Sales Location].[Country Name].&[Australia],[Retail Category].[Retail Category].[All])
CELL PROPERTIES VALUE, FORMAT_STRING, LANGUAGE, BACK_COLOR, FORE_COLOR, FONT_FLAGS
This produces the following results (snippet only):
The rows are months, and because of the method of retrieval, I need the months to also be displayed in a column.
So I tried this:
WITH
MEMBER [TheDate] AS [Retail Sales Date].[Month].CurrentMember.Name
SELECT {
[TheDate],
[Measures].[Dollar Amount],
[Measures].[Transaction Count]}
DIMENSION PROPERTIES PARENT_UNIQUE_NAME,HIERARCHY_UNIQUE_NAME ON COLUMNS,
NON EMPTY Hierarchize({DrilldownLevel({[Retail Sales Date].[Month].[All]},,,INCLUDE_CALC_MEMBERS)})
DIMENSION PROPERTIES PARENT_UNIQUE_NAME,HIERARCHY_UNIQUE_NAME ON ROWS
FROM [Retail Sales Cube]
WHERE ([Geography].[Retail Sales Location].[Country Name].&[Australia],[Retail Category].[Retail Category].[All])
CELL PROPERTIES VALUE, FORMAT_STRING, LANGUAGE, BACK_COLOR, FORE_COLOR, FONT_FLAGS
which would be fine, except that it also shows rows where there are null values, as follows:
I know there is NONEMPTY, but I don't know where I would put it. How can I get rid of the empty rows?

Answer 1

Perhaps the following expression would do the trick:
WITH
MEMBER [TheDate] AS
IIF( !isEmpty( [Dollar Amount] )
[Retail Sales Date].[Month].CurrentMember.Name,
null
)
