Mdx 如何覆盖SSAS商业智能&x27；货币兑换'；用于负债计算

我正在AnalysisServices中设置一个新的多维数据集，并使用商业智能向导解决货币转换问题。现在，这一切都完美地工作了，钱在叶子级别被转换，并汇总起来显示在用户选择的报表货币中

我现在的问题是责任的计算。对于负债，我需要将每种货币的金额相加，然后使用最新的“日终汇率”进行转换。我将“日终率”作为最后一个非空指标，但我看不出如何避免叶级转换，如下所示：

// This is the Many to One section  
// All currency conversion formulas are calculated for the pivot currency and at leaf of the time dimension 
Scope ({ Measures.[Money] } ); 
  Scope( Leaves([Date]) ,[Reporting Currency].[GBP], Leaves([Currency])); 

    // Convert Local value into Pivot currency for selected Measures that must be         converted with Measure rate [End Of Day Rate] 
        Scope( { Measures.[Money] } )
            This = [Reporting Currency].[Local] * Measures.[End Of Day Rate]; 
        End Scope; 
  End Scope;    

  // This is the One to Many section
  // All currency conversion formulas are calculated for the non pivot currency and at leaf of the time dimension   
  Scope( Leaves([Date]) , Except([Reporting Currency].[Currency].[Currency].Members, {[Reporting Currency].[Currency].[Currency].[GBP], [Reporting Currency].[Currency].[Currency].[Local]})); 

    // This section overrides the local values with the Converted value for each selected measures needing to be converted with Measure rate [End Of Day Rate]… 
    // LinkMember is used to reference the currency from the source currency dimension in the rate cube. 
    Scope( { Measures.[Money] } ); 
        This = [Reporting Currency].[Currency].[GBP] / (Measures.[End Of Day Rate], LinkMember([Reporting Currency].[Currency].CurrentMember, [Currency].[Currency])); 
    End Scope;

  End Scope;  // Leaves of time, all reporting currencies but local and pivot currency  
End Scope;  // Measures

[货币]计量单位以不同的货币支付，每种货币都有一个货币维度和一个“日终汇率”

我计算负债的最佳方案是什么？我正在考虑复制[货币]度量值，但为了避免货币转换而增加额外度量值似乎是浪费——此外，在真实立方体中，还有几个度量值需要计算，因此它不仅仅是额外的度量值

其他人也面临类似的问题吗？

好吧，所以我最终创建了一个不可见的[Measures].[Money-Liability]，它不是由上述代码自动转换的，我在脚本中完成了以下计算：

[Measures].[Liability] = 
(
    SUM 
    ( [Currency].[Currency].[Currency], 
        SUM 
        ( 
            { NULL : [Date].[Date Key].CurrentMember }, 
           (   
                [Money - Liability]
            )
      ) 
      / [Measures].[End Of Day Rate] 
    ) 
    * (Measures.[End Of Day Rate], LinkMember([Reporting Currency].[Currency].CurrentMember, [Currency].[Currency]))
);
