仅 SSAS MDX YTD 最后值

Question

请你帮忙：

事实table a) 实际值

测量：每周流入这是基础数据库中的字段table [措施].[每周流入]

我使用以下方法计算年初至今的流入量

汇总 ( 截止日期 ( [期末].[期末].[年], [期间结束].[期间结束].CurrentMember ), [措施].[_每周流入] )

我想显示一个新的计算度量值，它将仅显示显示实际流入的最后一条记录的单个 YTD 流入值。这不能作为一个运行总数重复，只是一个值。请参阅所附示例： Screen shot 我如何使用计算的度量来实现这一目标？能否举个例子？

日期维度：See screen shot

添加MDX后请看截图3。不应显示粉红色背景的值。绿色背景者需出示：Screen Shot 3

所以您需要运行 BottomCount（1 行）在您的 [Measures] 上。[_Weekly Inflow] 以获得具有非空值 _Weekly Inflow 的最后一个元组，这将是一个计算的度量.接下来，在您的 YTD 度量中添加一个案例，检查 [Period End].[Period End] 用户层次结构的当前值到上述度量的唯一值。我手头没有示例多维数据集，但查询结构如下所示。

 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

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

    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
