动态度量的周期增长周期

Question

我写了一个mdx 脚本，显示互联网销售额的周期增长周期，一切正常。 我们正在使用一个界面，您可以在其中放置一个切片器，以便用户可以选择他感兴趣的 date.Calendar 的维度，即用户决定选择的 Date.Calendar 的任何维度（Quarter，Month，Year）它将正确看看以前的成员。现在，我试图为 Measure 获取相同的值 - 即我希望它能够灵活地依赖于用户将在切片器中选择的度量（即 Internet 税额）。

我想不出一种方法来创建具有灵活度量的先前成员...

WITH
MEMBER [Measures].[Internet Sales Amount PP] AS
(
[Date].[Calendar].CurrentMember.Prevmember,
[Measures].[Internet Sales Amount]
)
MEMBER [Measures].[Period on Period Grwth %] AS
IIF (
    [Measures].[Internet Sales Amount PP] = 0,
    'N/A',
    ([Measures].[Internet Sales Amount]-[Measures].[Internet Sales Amount PP]) /[Measures].       [Internet Sales Amount PP]
    )
,FORMAT_STRING = "percent"
SELECT
 [Date].[Calendar].[Month] ON ROWS,

 {[Measures].[Internet Sales Amount],
 [Measures].[Internet Sales Amount PP],
 [Measures].[Period on Period Grwth %]} ON COLUMNS
FROM [Adventure Works]

Answer 1

如果您碰巧使用 SSRS，您可以添加一个参数来吸收从前端的下拉列表中选择的度量。我们在 SharePoint 环境中托管 SSRS，我们就是这样做的。

WITH
MEMBER [Measures].[Measure Growth PP] AS
(
[Date].[Calendar].CurrentMember.Prevmember,
strtomember('[Measures].'+ @MeasureSelected)
)
MEMBER [Measures].[Period on Period Grwth %] AS
IIF (
    [Measures].[Measure Growth PP] = 0,
    'N/A',
    (strtomember('[Measures].'+ @MeasureSelected)-[Measures].[Measure Growth PP]) /
    [Measures].[Measure Growth PP]
    )
,FORMAT_STRING = "percent"
SELECT
 [Date].[Calendar].[Month] ON ROWS,

 {strtomember('[Measures].'+ @MeasureSelected),
 [Measures].[Measure Growth PP],
 [Measures].[Period on Period Grwth %]} ON COLUMNS
FROM [Adventure Works]
