I've been playing with a script of Chris Webb's found here: http://cwebbbi.wordpress.com/2007/06/25/advanced-ranking-and-dynamically-generated-named-sets-in-mdx/
The adapted script is this:
WITH
SET MyMonths AS
TopPercent
(
[Date].[Calendar].[Month].MEMBERS
,20
,[Measures].[Reseller Sales Amount]
)
SET MyEmployees AS
[Employee].[Employee].[Employee].MEMBERS
SET MyMonthsWithEmployeesSets AS
Generate
(
MyMonths
,Union
(
{[Date].[Calendar].CurrentMember}
,StrToSet
("
Intersect({},
{TopCount(MyEmployees, 10, ([Measures].[Reseller Sales Amount],[Date]. [Calendar].CurrentMember))
as EmployeeSet"
+
Cstr(MyMonths.CurrentOrdinal)
+ "})"
)
)
)
MEMBER [Employee].[Employee].[RestOfEmployees] AS
Aggregate
(
Except
(
MyEmployees
,StrToSet
(
"EmployeeSet" + Cstr(Rank([Date].[Calendar].CurrentMember,MyMonths))
)
)
)
MEMBER [Measures].[EmployeeRank] AS
Rank
(
[Employee].[Employee].CurrentMember
,StrToSet
(
"EmployeeSet" + Cstr(Rank([Date].[Calendar].CurrentMember,MyMonths))
)
)
SELECT
{
[Measures].[EmployeeRank]
,[Measures].[Reseller Sales Amount]
} ON 0
,Hierarchize
(
Union
(
Filter
(
MyMonthsWithEmployeesSets * MyEmployees //<<<HERE<<<<
,
[Measures].[EmployeeRank] >= 1
)
,{
MyMonthsWithEmployeesSets * [Employee].[Employee].[RestOfEmployees]
}
)
) ON 1
FROM [Adventure Works];
How do I ORDER
the output so that each set of ten employees is in order 1 to 10, with the MEMBER
called RestOfEmployees
always found in position 11 i.e. it should follow the member ranked 10 ?
The temptation is to add the ORDER
function at the point marked HERE
i.e. that line will become :
MyMonthsWithEmployeesSets * ORDER(MyEmployees, [Measures].[EmployeeRank])
Doing that results in the following error message:
The dimension '[EmployeeSet0]' was not found in the cube when the string, [EmployeeSet0], was parsed.
I believe this is because the measure EmployeeRank
uses the inline sets created during the generate function.
If you redefine EmployeeRank
to be 11 for RestOfEmployees
, you can just add that member to the set that is the first argument to Filter
, and than apply Order
, as it will sort after position 1 to 10:
WITH
SET MyMonths AS
TopPercent
(
[Date].[Calendar].[Month].MEMBERS
,20
,[Measures].[Reseller Sales Amount]
)
SET MyEmployees AS
[Employee].[Employee].[Employee].MEMBERS
SET MyMonthsWithEmployeesSets AS
Generate
(
MyMonths
,Union
(
{[Date].[Calendar].CurrentMember}
,StrToSet
("
Intersect({},
{TopCount(MyEmployees, 10, ([Measures].[Reseller Sales Amount],[Date]. [Calendar].CurrentMember))
as EmployeeSet"
+
Cstr(MyMonths.CurrentOrdinal)
+ "})"
)
)
)
MEMBER [Employee].[Employee].[RestOfEmployees] AS
Aggregate
(
Except

MyEmployees
,StrToSet

"EmployeeSet" + Cstr(Rank([Date].[Calendar].CurrentMember,MyMonths))
