MDX How to get total distict count and SUM of subgroups?

Question

with
MEMBER Measures.[EmailCount] as IIF(ISEMPTY([Measures].[Tran Count]), 0 ,[Measures].[Tran Count])
MEMBER Measures.AdvGroupTotal as
SUM (
FILTER( EXISTING ([Dim IFA Details].[Parent Key].[Adviser Group].Members * [Dim Date].[Fiscal].[Fiscal Year].members )
, Measures.[Amount] > 100 )
, Measures.[Amount])
MEMBER Measures.[AdvGrpCount] as
distinctCOUNT(Existing([Dim IFA Details].[Parent Key].[Adviser Group].Members * [Dim Date].[Fiscal].[Fiscal Year].members))
member Measures.IncomePerEmail as Measures.AdvGroupTotal /Measures.[EmailCount]
member Measures.AvgIncomePerFirm as Measures.AdvGroupTotal/ Measures.AdvGrpCount
SELECT { [Measures].[Amount] , Measures.[EmailCount], Measures.AdvGroupTotal, Measures.[AdvGrpCount],
Measures.IncomePerEmail, Measures.AvgIncomePerFirm }
ON COLUMNS,
[Dim Date].[Fiscal Year].[Fiscal Year].ALLMEMBERS * [Dim Date].[Fiscal Quarter].[Fiscal Quarter].ALLMEMBERS *
Except( [Dim Income Range].[Hierarchy].[Range ID].Members , [Dim Income Range].[Hierarchy].[All].UNKNOWNMEMBER.UNKNOWNMEMBER )
on rows
FROM [Income and Emails Cube]
where
[Dim Date].[Fiscal].[Fiscal Year].&[FY 13/14]
The query above returns :
How can I get Totals for AdvGroupTotal and AdvGroupCount for the year ?
In the above case I want to tally up 1586 + 67 + 155 + 12 + 1718 for AdvGroupCount, same applies for the corresponding
AdvGroupTotal figures.
Seems simple enough, but I seem unable to come up with a way around this.

Answer 1

I worked it out with the help of Simon from another forum.
Using a filtered set will get me the result required. It is however not very quick, so I probably should look into building it into the cube.
WITH SET [Filtered Groups] AS
( Filter (
{ [Dim IFA Details].[Parent Key].[Adviser Group] } *
{ [Dim Date].[Fiscal Year].CurrentMember },
[Measures].[Amount] > 100
MEMBER [Measures].[Annual] AS
Sum ( [Filtered Groups], Measures.[Amount] )
MEMBER [Measures].[Firm Count] AS
DistinctCount ( [Filtered Groups] )
MEMBER [Measures].[Avg Income Per Firm] AS
[Measures].[Annual] / [Measures].[Firm Count]
MEMBER [Measures].[Test] AS
Sum (
{ [Dim Date].[Fiscal Quarter].[Fiscal Quarter] } * { [Dim Income Range].[Hierarchy].[Range ID] } * { [Filtered Groups] },
[Measures].[Amount]
MEMBER [Measures].[TotalCount] AS
DistinctCount (
{ [Dim Income Range].[Hierarchy].[Range ID] } * { [Filtered Groups] }
MEMBER [Measures].[TotalAvg] as [Measures].[Test]/ [Measures].[TotalCount]
MEMBER [Measures].[Quarter] as [Measures].[Amount]
SELECT
{ [Measures].[Quarter], [Measures].[Annual], [Measures].[Firm Count], [Measures].[Avg Income Per Firm],
[Measures].[Test], [Measures].[TotalCount], [Measures].[TotalAvg] } ON COLUMNS,
[Dim Date].[Fiscal Year].[Fiscal Year].AllMembers * [Dim Date].[Fiscal Quarter].[Fiscal Quarter].AllMembers *
Except ( [Dim Income Range].[Hierarchy].[Range ID].Members, [Dim Income Range].[Hierarchy].[All].UnknownMember.UnknownMember )
DIMENSION PROPERTIES Member_Unique_Name, MEMBER_CAPTION
ON ROWS
FROM [Income and Emails Cube]
WHERE [Dim Date].[Fiscal].[Fiscal Year].&[FY 13/14]
