SSRS mdx报告：通过多值参数的最大排名值的计算成员

Question

这是对MS OLAP多维数据集的一个简单的mdx查询，它输出3个城市的销售步骤统计数据，每个销售阶段的排名，它工作正常：

WITH 
MEMBER [Measures].[rank] AS 

    case [Sales_step].currentmember.member_caption         
    when 'Contacts' then 1    
    when 'Clients' then 2
    when 'Funded' then 3 
    else 0 end

SELECT {[Measures].[rank],
        [Measures].[qnt]} ON COLUMNS,

NON EMPTY     
       crossjoin({[City].CHILDREN},                            
                 {[Sales_step].CHILDREN}) ON ROWS 

FROM ( SELECT ( STRTOSET(@[Sales_step], CONSTRAINED) ) ON COLUMNS  
FROM [SALES_PIPE])

输出结果为：

现在我想为每个城市建立总计而没有单独的销售步骤，但仅显示最大的存档销售阶段排名。结果必须是：

我尝试了以下代码来执行此操作：

WITH 
MEMBER [Measures].[rank max] AS 

    case [Sales_step].currentmember.member_caption         
    when 'Contacts' then 1    
    when 'Clients' then 2
    when 'Funded' then 3 
    else 0 end

SELECT {[Measures].[rank max],
        [Measures].[qnt]} ON COLUMNS,

NON EMPTY [City].CHILDREN ON ROWS 

FROM ( SELECT ( STRTOSET(@[Sales_step], CONSTRAINED) ) ON COLUMNS  
FROM [SALES_PIPE])

它不会生成错误，但会为计算成员[Measures]返回空值。[rank max]：

仅当我将一个值传递给@ [Sales_step]参数时才有效。虽然我需要一个多值的参数运行。当我在case子句中更改了这个片段时：

case [Sales_step].currentmember.member_caption 

为：

case strtomember(@[Sales_step]).member_caption

它抛出错误“STRTOMEMBER函数需要1参数的成员表达式。使用了元组集表达式”。当我使用它时，错误也会触发单参数和多参数：

case strtoset(@[Sales_step]).currentmember.member_caption

我如何修改计算成员[Measures]。[rank max]以获得所需的结果，并且传递@ [Sales_step]多值参数的最大等级？

Answer 1

我想知道这样的事情是否有效：

WITH 
SET [S] AS
    NonEmpty(
       EXISTING [Sales_step].CHILDREN,
       ([City].CURRENTMEMBER, [Measures].[qnt])   //<<I think that [City].CURRENTMEMBER is probably redundant in this tuple
    )
MEMBER [Mx] AS   
    CASE         
      WHEN INTERSECT([S], {[Sales_step].[Funded]}).COUNT = 1 THEN 3 
      WHEN INTERSECT([S], {[Sales_step].[Clients]}).COUNT = 1 THEN 2 
      WHEN INTERSECT([S], {[Sales_step].[Contacts]}).COUNT = 1 THEN 1
    END
