Question

请您提供帮助：

事实表 a）实际情况

度量：每周流入，这是基础数据库表中的字段 [措施]。[每周流入量]

我使用以下方法计算YTD流入量

汇总（ PeriodsToDate （ [期末]。[期末]。[年]， [Period End]。[Period End] .CurrentMember ）， [措施]。[_每周流入] ）

我想显示一个新的计算得出的度量，该度量仅对显示实际流入的最后一条记录显示单个YTD流入值。不得重复此操作，因为运行总计仅是一个值。请参见所附示例： Screen shot 如何使用计算出的度量来实现？请您提供一个例子吗？

日期维度：See screen shot

添加MDX后，请参阅屏幕截图3。不应显示带有粉红色背景的值。需要呈现绿色背景的人：Screen Shot 3

因此，您需要在[Measures]。[_ Weekly Inflow]上运行BottomCount（1行），以获取最后一个具有非_Weekly Inflow值的元组，这将是计算得出的度量值。度量将一个案例检查[Period End]。[Period End]用户层次结构的当前值添加到上述度量的唯一值。我手边没有示例多维数据集，但查询结构将如下所示。

 with member Measures.[NewColumn]
as 
(bottomcount(
nonempty(
existing
{([Date].[Date].[Date].members)}
,[Measures].[_Weekly Inflow]),
1
).item(0).Name

member 
Measures.[YTD]
as 
case when [Period End].[Period End].currentmember.name=Measures.[NewColumn] then 
Aggregate ( PeriodsToDate ( [Period End].[Period End].[Year], [Period End].[Period End].CurrentMember ), [Measures].[_Weekly Inflow] )
else 
null end

编辑

with member Measures.[NewColumn]
    as 
    (bottomcount(
    filter(
    existing
    {([Date].[Date].[Date].members)}
    ,[Measures].[_Weekly Inflow]>0),
    1
    ).item(0).Name

    member 
    Measures.[YTD]
    as 
    case when [Period End].[Period End].currentmember.name=Measures.[NewColumn] then 
    Aggregate ( PeriodsToDate ( [Period End].[Period End].[Year], [Period End].[Period End].CurrentMember ), [Measures].[_Weekly Inflow] )
when 
[Period End].[Period End].currentmember.name=[Period End].[Period End].defaultmember then Aggregate ( PeriodsToDate ( [Period End].[Period End].[Year], [Period End].[Period End].CurrentMember ), [Measures].[_Weekly Inflow] )
    else 
    null end

修改

    member 
    Measures.[YTD]
    as 
    case when [Period End].[Period End].currentmember.name=Measures.[NewColumn] then 
    Aggregate ( PeriodsToDate ( [Period End].[Period End].[Year], [Period End].[Period End].CurrentMember ), [Measures].[_Weekly Inflow] )
when 
[Period End].[Period End].currentmember.name="Feburary 2018" then Aggregate ( PeriodsToDate ( [Period End].[Period End].[Year], [Period End].[Period End].CurrentMember ), [Measures].[_Weekly Inflow] )
    else 
    null end

仅SSAS MDX YTD最后值
