如何在 MDX 中获取最后的销售价格

Question

MDX return 可以按照下面的代码得到预期结果吗？有如下数据：

DATA:       
ItemID  DateKey Price
A   20151230    4.85
A   20150520    5.5
A   20150325    4.65
B   20140130    3
B   20141130    5
B   20150630    4.5

Wrong Result:
ItemID  DateKey Price
A   20151230    4.65
B   20150630    3

Expected Result:
ItemID  DateKey Price
A   20151230    4.85
B   20150630    4.5

WITH MEMBER [LastDate] AS tail (Filter([BI Dim Date].[Date Key].[Date Key],[Measures].[PRICE])).Item(0).name
MEMBER [LastDateWithSales] AS Filter([MyTest].[PRICE].[PRICE],[Measures].[LastDate]).Item(0).name

SELECT { [LastDate], [LastDateWithSales]} ON columns,
[MyTest].[ITEMID].[ITEMID] on rows
FROM [MyCube]

执行上面的MDX，结果不对。请指教

WITH MEMBER [LastDate] AS 
  tail (
     NonEmpty(
        [BI Dim Date].[Date Key].[Date Key].Members
       ,[Measures].[PRICE]
     )
   ).Item(0).Item(0).name
MEMBER [LastDateWithSales] AS 
  tail (
     NonEmpty(
       [BI Dim Date].[Date Key].[Date Key].Members 
     * [Measures].[PRICE]
     )
   ).Item(0)

SELECT 
{ [Measures].[LastDate], [Measures].[LastDateWithSales]} ON columns,
[MyTest].[ITEMID].[ITEMID] on rows
FROM [MyCube]
