MDX: How to get dimension count - sql-server-2008

Question

I execute this query and gives me this error:
Infinite Recursion Detected: The loop of dependencies is: Direct Reporting->Direct Reporting.
Can anybody help me?
WITH
MEMBER [Measures].[Direct Reporting] AS COUNT([Employee].[Employees].Members, EXCLUDEEMPTY)
SELECT
{[Measures].[Direct Reporting]} ON COLUMNS,
{[Geography].[Country].AllMembers} ON ROWS
FROM [Adventure Works]

Answer 1

You've picked a special type of hierarchy: a parent/child hierarchy.
Here is an example of a count against the advWks cube:
WITH
MEMBER [Measures].[aCount] AS
Sum
(
(
[Customer].[Customer].[Customer]
,[Customer].[Customer Geography].CurrentMember
)
,IIF
(
[Measures].[Internet Order Quantity] > 50
,1
,0
)
)
SELECT
{
[Measures].[Direct Reporting]
,[Measures].[Internet Order Count]
} ON COLUMNS
,{[Customer].[Customer Geography].[Country].MEMBERS} ON ROWS
FROM [Adventure Works];

Answer 2

Specifying Count with EXCLUDEEMPTY means the engine needs to evaluate the cube's cells referenced by each member of the dimension and the current [Measures]. Not 100% sure about SSAS behavior but it seems the current [Measures] is the calc. measure being defined itself: hence the infinite loop.
To fix it, you can explicitly define the [Measures]:
WITH MEMBER [Measures].[Direct Reporting] AS
COUNT( { [Measures].[use-here-your-measure] } * [Employee].[Employees].Members, EXCLUDEEMPTY)
Or perhaps use the NonEmpty function:
AS Count( NonEmpty( [Employee].[Employees].Members,
[Measures].[use-here-your-measure] ))
Hope that helps.
