Dynamic SSRS MDX数据集需要动态字段源，是否有解决方法？

我在下面的MDX查询中遇到了一个问题。问题在于TOPCOUNT，我使用案例陈述来计算我在计算什么

INVESTOR、ADVISER和ADVISERGROUP实际上都是同一维度，链接到事实表中的不同字段，即ADVISER的维度是Entity.IDKey->fact.advisorkey，INVESTOR的维度是Entity.IDKey->fact.InvestorKey

因此，问题是所有数据集都将返回相同的字段名，[ID KEY]，但会有不同的位置，即数据集字段源定义需要不同

在SSRS中，它只适用于一种情况，即它在设计时运行的情况，而其他情况下返回的结果不正确。 这有什么办法吗

WITH MEMBER [Measures].[Previous Period] as
(   [Measures].[Fact TOL Activity Count] ,  
ParallelPeriod(
        IIF(@GroupBy = 'Y',   [Date].[Fiscal].[Fiscal Year],IIF(@GroupBy = 'Q' ,  [Date].[Fiscal].[Fiscal Quarter], [Date].[Fiscal].[Fiscal Month]))  
    , 1 
    ,[Date].[Fiscal].CurrentMember ))


MEMBER [Measures].[Current Period] as [Measures].[Fact TOL Activity Count] 

MEMBER [Measures].[CPeriod] as [Date].[Fiscal].CurrentMember.Name

MEMBER [Measures].[PPeriod] as 
ParallelPeriod(
      IIF( @GroupBy = 'Y',   [Date].[Fiscal].[Fiscal Year], IIF(  @GroupBy = 'Q' ,  [Date].[Fiscal].[Fiscal Quarter], [Date].[Fiscal].[Fiscal Month]))
    , 1 
    ,[Date].[Fiscal].CurrentMember ).Name

MEMBER [Measures].[Growth] as 

IIF (ISEMPTY([Measures].[Previous Period]), 0 , 
[Measures].[Fact TOL Activity Count]/ [Measures].[Previous Period] ), FORMAT = "Percent"


SELECT
{   
     [Measures].[Previous Period], [Measures].[Current Period],  [Measures].[Growth], [Measures].[PPeriod],[Measures].[CPeriod]

} ON COLUMNS,


(  TopCount(
    Except({

    CASE  [Dim User Type].[User Type Key].CurrentMember.NAME  
            WHEN "Adviser" THEN  [ADVISER].[ID Key].children 
            WHEN "Firm" THEN  [ADVISERGROUP].[ID Key].children
            WHEN "Investor" THEN [INVESTOR].[ID Key].children
            ELSE [INVESTMENTMANAGER].[ID Key].children 
    END

    } ,  

    CASE  [Dim User Type].[User Type Key].CurrentMember.NAME  
            WHEN "Adviser" THEN  [ADVISER].[ID Key].[Unknown]
            WHEN "Firm" THEN  [ADVISERGROUP].[ID Key].[Unknown]
            WHEN "Investor" THEN [INVESTOR].[ID Key].[Unknown]
            ELSE [INVESTMENTMANAGER].[ID Key].[Unknown]
    END
)

, 10
, (   [Measures].[Growth],  STRTOMEMBER(@CurrentPeriod, CONSTRAINED), [Dim EVENTTYPE].[IASEVENTTYPEKEY].&[ET00000040], STRTOMEMBER(@UserTypeKey, CONSTRAINED))
   )) on rows


FROM  [TOL Metrics Usage]

where  ( [Dim EVENTTYPE].[IASEVENTTYPEKEY].&[ET00000040],  STRTOMEMBER(@UserTypeKey, CONSTRAINED), STRTOMEMBER(@CurrentPeriod, CONSTRAINED) )

您将@UserTypeKey作为参数。因此，您可以根据基于此参数的报告进行定位

如果希望基于名称进行筛选，而不希望仅为该名称创建另一个数据集，则还可以添加另一个计算成员

MEMBER [Measures].[UserTypeKeyName] AS [Dim User Type].[User Type Key].CurrentMember.NAME
