MDX -Children count function Not working in Case statement

Question

Hi,
I am trying to create set when you slice with the Hierarchy member is leaf level , I want a output only that Leaf level .
and When I slice with  the parent level , it has to give all the members below that parent level.
But the problem here is when I select child member or leaf member , The first condition in the Case is not working
WITH SET
TESTSET AS
CASE
WHEN
 [Dimension].[Hierarchy].currentmember.children.count<0
THEN
 [Dimension].[Hierarchy].currentmember
ELSE
 DESCENDANTS([Dimension].[Hierarchy].Currentmember,,AFTER)
END
SELECT
WBSSET ON 1,
{} on 0
FROM
 (SELECT {[Dimension].[Hierarchy].&[10]} ON COLUMNS FROM [CubeName])
Thanks,
Santosh

Hi Santosh,
I don't think Children count function not working in case statement, I have tested it on my local environment, here s the sample query for you reference.
with member
testset as
case
when
[Geography].[Geography].currentmember.children.count<10
then "X"
else "OK"
end
select testset on 0,
{[Geography].[Geography].[Country].members} on 1

In your scenario, the issue might be caused by the query isself, you can try to use IsLeaf Funcion to achieve your requirement. Please refer to the links below.
