How to write MDX Query for getting grouped results - sql-server

Question

I have Cube where data is aggregated and all I need to have count of records against each 2 digit zip code.
Attached image shows my cube hierarchies and measures.
I applied query like :
WITH MEMBER [Measures].NoOfConsignments as Count(([Consignment].[Target Address Name].[Target Address Name]))
select filter([Consignment].[Distribution Area].[Zip2], [Consignment].[Distribution Area].[Target Address Country] = "94") on rows,
{[Measures].NoOfConsignments} on columns
from [RebellOlap]
where ({[Consignment].[Distribution Area].[Target Address Country].&[94]})
but is throwing an error :
"The Distribution Area hierarchy already appears in the Axis1 axis"
I re-structured and formulated following sub-select query in the following way :
WITH MEMBER [Measures].NoOfConsignments as Count(([Consignment].[Target Address Name].[Target Address Name]))
Select
NON EMPTY [Measures].NoOfConsignments on columns,
NON EMPTY [Consignment].[Distribution Area].[Zip2] on rows
FROM (
SELECT {[Consignment].[Distribution Area].[Zip2],[Consignment].[Distribution Area].[Target Address Country].&[94]}
FROM [RebellOlap]
)
but it also returned me the 'ambiguity error'.
all I need Output in following manner
Edit
AllConsignments in Germany
All Consignments in Germany against specific Zip Code

Answer 1

I just applied filter for all zip codes and introduce "Range" as Operator with 'Filter Expression' and it worked!!
SELECT NON EMPTY { [Measures].[ConsignmentCount] } ON COLUMNS,
NON EMPTY { ([Consignment].[Distribution Area].[Zip2].ALLMEMBERS ) } ON ROWS
FROM ( SELECT ( [Consignment].[Distribution Area].[Zip2].&[94]&[0]&[01] : [Consignment].[Distribution Area].[Zip2].&[94]&[9]&[99] ) ON COLUMNS
FROM [RebellOlap])

Based on your edits, I feel below should work out for you:
WITH MEMBER Measures.NumConsignment as
COUNT
(
NonEmpty
(
[Consignment].[Target Address Name].[Target Address Name].MEMBERS,
([Consignment].[Distribution Area].CURRENTMEMBER, Measures.[Num. Consignments])
)
)
SELECT [Consignment].[Distribution Area].[Zip2].MEMBERS on 1,
Measures.NumConsignment ON 0
FROM
(
SELECT [Consignment].[Distribution Area].[Target Address Country].&[94] ON 0
FROM [RebellOlap]
)
While the rest of the code is pretty standard, there is one part which might need explanation.
NonEmpty
(
[Consignment].[Target Address Name].[Target Address Name].MEMBERS,
([Consignment].[Distribution Area].CURRENTMEMBER, Measures.[Num. Consignments])
)
This is returning a set of those Target addresses for the current zip for whom the num of consignments is not empty( i.e. <>0)
