Question

我正在尝试计算通过SSRS中的参数传递的日期范围的运行总计。我知道我需要使用滞后功能，但我无法做到正确。我尝试使用以下

WITH MEMBER [Measures].[Rolling12Months] AS 
   SUM( 
     [Reporting Period].[Fiscal].[Fiscal Month Name].&[1]&[2013] : [Reporting Period].[Fiscal].CURRENTMEMBER,
     [Measures].[Amount]
   )

Answer 1

下面的脚本将执行@ whytheq脚本的操作，仅动态。它根据当前成员计算出过去12个月，您可以将其作为切片器传递，或者当您处于设置上下文中时，可能不需要切片器轴。我假设你认为你需要LAG函数。

WITH SET Last12Months AS
{[Reporting Period].[Fiscal].CURRENTMEMBER.LAG(12) : [Reporting Period].[Fiscal].CURRENTMEMBER}

MEMBER [Measures].[Rolling12Months] AS 
SUM( 
    Last12Months,
    [Measures].[Amount]
   )


SELECT
     [Measures].[Rolling12Months]  ON 0
    , [Reporting Period].[Fiscal].[Fiscal Month Name].Members ON 1
FROM [YourCubeName]
WHERE [Reporting Period].[Fiscal].[Fiscal Month Name].&[1]&[2014] 
//`WHERE` clause can be left out if context is already set.

Answer 2

您的脚本看起来不错 - 也许只需更改为Aggregate：

WITH MEMBER [Measures].[Rolling12Months] AS 
   Aggregate(
      [Reporting Period].[Fiscal].[Fiscal Month Name].&[1]&[2013]:[Reporting Period].[Fiscal].CurrentMember,
      [Measures].[Amount]
    )

所以完整的脚本就像

WITH MEMBER [Measures].[Rolling12Months] AS 
   Aggregate(
      [Reporting Period].[Fiscal].[Fiscal Month Name].&[1]&[2013]:[Reporting Period].[Fiscal].CurrentMember,
      [Measures].[Amount]
   )
SELECT
    {[Measures].[Amount]
    , [Measures].[Rolling12Months] } ON 0
    , [Reporting Period].[Fiscal].[Fiscal Month Name].Members ON 1
FROM [YourCubeName]
