I have a Situation where I am looking for MDX Guidance.
Environment: SQL Server 2008 R2,SSRS 2008 R2
Dimension:Columns DimMainProvider :ProviderName DimAcademicYear:AcademicYear DimSectorSubjectArea:Estyn DimLearningAim:LearningAimReference
Fact:Columns Learnings:MainProviderKey,AgeBandKey,LearningAimKey,SuccessFlag
What I want is 1) For a particular MainProvider Get Top 10 LearningAims by Success Rate and show it in tablix 2) For a each Row on tablix also show Box plot graph which essentially needs Min,Max,Quartile1,Quartile3 success rates of that particular LearningAim across all Mainproviders
What I have is 2 MDX queries
a) one which gets top 10 Activities for a Main Provider (Simplified Version of MDX below)
WITH
SET Top10LearningAimsForSuccessRate
AS
NonEmpty(
TOPCOUNT([ReportedLearningAims],10,[Measures].[SuccessRate]),
[Measures].[SuccessRate]
)
SELECT
{
[Measures].[SuccessRate]
} ON COLUMNS
,NON EMPTY
{
EXISTS(
Top10LearningAimsForSuccessRate
,,"Learnings")
} ON ROWS
FROM
(
SELECT {[Measures].[TerminatedAssessableLASum]
,[Measures].[SuccessfulLASum]} ON COLUMNS
,{(StrToSet("[DimMainProvider].[Provider开发者_运维百科Name].&[44]",CONSTRAINED))} On ROWS
FROM [FECube]
)
WHERE
( StrToSet("[DimAcademicYear].[AcademicYear].[AcademicYear].[2009/10]",CONSTRAINED),
StrToSet("[DimSectorSubjectArea].[Estyn].&[2]",CONSTRAINED)
)
b) Another query which accepts LearningAim as a Parameter and does Statistical Calculations and gives me values (Simplified Version of MDX below)
WITH
SET ProviderwideLearningAims
AS
ORDER(
NonEmpty( [DimMainProvider].[ProviderName].[ProviderName],
[Measures].[SuccessRate]
)
,[Measures].[SuccessRate],BASC
)
MEMBER [Measures].[MaxValue]
AS
Max(ProviderwideLearningAims,[SuccessRate]),FORMAT_STRING = "Percent"
MEMBER [Measures].[MinValue]
AS
Min(ProviderwideLearningAims,[SuccessRate]),FORMAT_STRING = "Percent"
MEMBER [Measures].[MedianValue]
AS
Median(ProviderwideLearningAims,[SuccessRate]),FORMAT_STRING = "Percent"
Member [Measures].[ProviderCount] As [ProviderwideLearningAims].Count
MEMBER [Measures].[MeanValue]
AS
(SUM(ProviderwideLearningAims,[SuccessRate])/[Measures].[ProviderCount]),FORMAT_STRING = "Percent"
MEMBER [Measures].[LearningAimUniqueName]
AS
[DimLearningAim].[LearningAimReference].CurrentMember.UniqueName
Select
{ [Measures].[LearningAimUniqueName]
,[Measures].[MinValue]
,[Measures].[MaxValue]
,[Measures].[MedianValue]
,[Measures].[MeanValue]
} ON COLUMNS,
{
NonEmpty([DimLearningAim].[LearningAimReference].[LearningAimReference],ProviderwideLearningAims)
} ON ROWS
FROM
(
SELECT
StrToSet("[DimLearningAim].[LearningAimReference].&[50024991]",CONSTRAINED) ON COLUMNS
FROM [FECube]
)
WHERE
( StrToSet("[DimAcademicYear].[AcademicYear].[AcademicYear].[2009/10]",CONSTRAINED),
StrToSet("[DimSectorSubjectArea].[Estyn].&[2]",CONSTRAINED)
)
My original Idea is to fire 2nd query for each Learning Aim received from 1st query,but I am not able to implement this in SSRS Dataset Model. So Now I am back at MDX level and want somehow to merge these two.
Here is how I fixed it with help from Deepak Puri on MSDN forums
With Set [Top10LearningAims] as TOPCOUNT(
Filter(([ReportedLearningAims]*[DimMainProvider].[ProviderName].MEMBERS),[DimMainProvider].[ProviderName].CURRENTMEMBER IS STRTOMEMBER("[DimMainProvider].[ProviderName].&[44]") ) ,10,[Measures].[TerminatedAssessableLASum] )
MEMBER [Measures].[MaxValue] AS Max(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate]), [Measures].[SuccessRate]),FORMAT_STRING = "Percent" MEMBER [Measures].[MinValue] AS Min(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate]), [Measures].[SuccessRate]),FORMAT_STRING = "Percent" MEMBER [Measures].[MedianValue] AS Median(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate]), [Measures].[SuccessRate]), FORMAT_STRING = "Percent"
MEMBER [Measures].[MeanValue] AS Avg(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate]), [Measures].[SuccessRate]), FORMAT_STRING = "Percent"
Member [Measures].[ProviderCount] as Count(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate])) Member [Measures].[PercentileInt25] as Int((([Measures].[ProviderCount] - 1) * 25) / 100) Member [Measures].[PercentileFrac25] as (([Measures].[ProviderCount] - 1) * 25) / 100 - [Measures].[PercentileInt25] Member [Measures].[PercentileLo25] as ([Measures].[SuccessRate], Order(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate]), [Measures].[SuccessRate], BASC).Item([Measures].[PercentileInt25]).Item(0)), FORMAT_STRING = "Percent" Member [Measures].[PercentileHi25] as ([Measures].[SuccessRate], Order(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate]), [Measures].[SuccessRate], BASC).Item([Measures].[PercentileInt25] + 1).Item(0)), FORMAT_STRING = "Percent" Member [Measures].[Percentile25Value] as ([Measures].[PercentileLo25] * (1 - [Measures].[PercentileFrac25])) + ([Measures].[PercentileHi25] * [Measures].[PercentileFrac25]), FORMAT_STRING = "Percent" Member [Measures].[PercentileInt75] as Int((([Measures].[ProviderCount] - 1) * 75) / 100) Member [Measures].[PercentileFrac75] as (([Measures].[ProviderCount] - 1) * 75) / 100 - [Measures].[PercentileInt75] Member [Measures].[PercentileLo75] as ([Measures].[SuccessRate], Order(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate]), [Measures].[SuccessRate], BASC).Item([Measures].[PercentileInt75]).Item(0)), FORMAT_STRING = "Percent" Member [Measures].[PercentileHi75] as ([Measures].[SuccessRate], Order(NonEmpty([DimMainProvider].[ProviderName].[ProviderName], [Measures].[SuccessRate]), [Measures].[SuccessRate], BASC).Item([Measures].[PercentileInt75] + 1).Item(0)), FORMAT_STRING = "Percent" Member [Measures].[Percentile75Value] as ([Measures].[PercentileLo75] * (1 - [Measures].[PercentileFrac75])) + ([Measures].[PercentileHi75] * [Measures].[PercentileFrac75]), FORMAT_STRING = "Percent"
