TopCount with filter or exists

Question

I have a user asking for a measure that returns the TOP 15 revenue accounts. I don't think that is possible but I can be wrong as I'm new to this. I believe I need to create a Set as doing
CREATE MEMBER
CURRENTCUBE.[Measures]....
Will not work.
So in excel 2013 I created a set like and returns the TOP 10 but I need to add a filter or some how to excluded to specific members of the parent client Dimension.
TopCount(
 [Clients].[Parent Clients].Children
 ,10
 ,[Measures].[Total Revenue]
But I need to exclude 2 Parent Clients ...I need to exclude New Clients, New Sales.
I try to use the EXCEPT function but that only leaves off one parent like
TopCount(
Except(
[Clients].[Parent Clients].Members,
[Clients].[Parent Clients].[Parent Client].&[New Sales]) ,
10,
[Measures].[Total Revenue]
The above MDX gives me back only 9 records instead of 10. I believe the except is striping one of even though New Sales isn't in the top 10.
So I need help getting the TOP 10 but to exclude 2 members from the dim even thought they may not be part of the TOP 10. And need TOP 10 to return 10 records.

Answer 1

thanks for the reply and the set within the {} gave me help as I didn't know you could have multiple members inside the except function. But the issue is when I create a dynamic set like
CREATE DYNAMIC SET CURRENTCUBE.[Top 15 Parent Client]
AS TopCount([Clients].[Parent Clients].[Parent Client], 10, [Measures].[Total Revenue]),
DISPLAY_FOLDER = 'Clients' ;
and user in excel uses this set [Top 15 Parent Client] we get the desire results but it the user adds another member from another Dim like Dim Finance. Instead of getting the Top 15 Clients within Finance Districts we get the Top 15 parent clients and thier
district. In excel we can get the results we want without using Top 15 Parent Client set and just use the DIm Parent Client and Dim Finace then do a filter via excel so the MDX from excel looks like this, which I'm trying to mmic in the Cube, is there away?
