创建计算的时间段层次结构 [英] Creating a Calculated Time Periods Hierarchy

问题描述

为了给最终用户更好的多维数据集浏览体验，我试图创建一个由计算所得成员组成的时间段层次结构.

In order to give a nicer Cube browsing experience to end users, I am trying to create a Time Periods hierarchy consisting of Calculated Members.

当前，我已在DSV中使用计算列"来创建一个列，该列的日期"表中的每一行都具有相同的值(值是All Time).然后在我的Date and Time维中，使用该计算列"创建了一个单层，单成员层次结构，如下所示:

Currently I have used a Calculated Column in my DSV to create a column with the same value on every row in my Dates table (value is All Time). Then within my Date and Time dimension I have created a single level, single member hierarchy using that Calculated Column, which looks like this:

现在我已经成功完成的工作是通过以下计算将时间段添加到我的Calendar层次结构中:

Now what I have already successfully done is add Time Periods to my Calendar hierarchy with the following calculation:

CREATE MEMBER CURRENTCUBE.[Completion Date].[Calendar].[All].[Last 30 Days]
 AS SUM(LastPeriods(30,StrToMember(
    "[Completion Date].[Calendar].[Day]."+
    "&["+CStr(Year(Now()))+"]&["+CStr(Month(Now()))+"]&["+CStr(Day(Now()))+"]"
))),VISIBLE = 1; 

这在Calendar层次结构上按预期工作:

This works as expected on the Calendar hierarchy:

但是我想将它们移到新的Time Periods层次结构中，以使它们很好地分开.

But I want to move these into the new Time Periods hierarchy to keep them nicely separated.

到目前为止，我已经尝试通过两种不同的方式来做到这一点:

So far I have tried to do this in two different ways:

1. 更改计算成员的目标层次结构.将CREATE MEMBER CURRENTCUBE.[Completion Date].[Calendar].[All].[Last 30 Days]更改为CREATE MEMBER CURRENTCUBE.[Completion Date].[Time Period].[All].[Last 30 Days].

将Calendar层次结构上的计算所得成员的可见性更改为VISIBLE = 0，并在Time Periods层次结构上创建引用它的第二个计算所得成员:(我尝试过使用和不使用函数)

Changing the Visibility of the Calculated Member on the Calendar hierarchy to VISIBLE = 0 and creating a second Caculated Member on the Time Periods hierarchy which references it: (I have tried with and without using the SUM() function)

CREATE MEMBER CURRENTCUBE.[Completion Date].[Time Period].[All].[Last 30 Days]
 AS SUM([Completion Date].[Calendar].[All].[Last 30 Days]),
VISIBLE = 1;

但是这些都不对我有用.所以我的问题是，我该如何完成我想要达到的目标?

But neither of these have worked for me. So my question is, How can I complete what I am trying to achieve?

我的最终目标是创建一个层次结构，用户可以将其拖到数据透视表中并查看以下内容(但要实际计算出时间段):

My end goal is to have a Hierarchy which the user can drag into a pivot table and see the following (but with the Time Periods actually calculated):

推荐答案

我已经用这种方式创建了相同的内容:

I've just created the same this way:

1)为名称为"All Time"的未过滤值添加虚拟属性 (键为整数，值为0)

1) Add dummy attribute for unfiltered values with the name 'All Time' (key is int with 0 value)

2)添加3个空成员

CREATE MEMBER CURRENTCUBE.[Report Date].[Time Period].[All].[Last 30 Days]
 AS 
null,
VISIBLE = 1;
CREATE MEMBER CURRENTCUBE.[Report Date].[Time Period].[All].[Last 60 Days]
 AS 
null,
VISIBLE = 1;
CREATE MEMBER CURRENTCUBE.[Report Date].[Time Period].[All].[Last 90 Days]
 AS 
null,
VISIBLE = 1;

3)比添加范围(我还有另一种键格式):

3) Than add scopes (I have another key format):

/* SCOPES */
SCOPE ([Report Date].[Time Period].[All].[Last 30 Days]);
THIS = Sum(LastPeriods(30,StrToMember("[Report Date].[Report Date].[Day].&["+CStr(Format(Now(),"yyyyMMdd"))+"]")));
END SCOPE;
SCOPE ([Report Date].[Time Period].[All].[Last 60 Days]);
THIS = Sum(LastPeriods(60,StrToMember("[Report Date].[Report Date].[Day].&["+CStr(Format(Now(),"yyyyMMdd"))+"]")));
END SCOPE;
SCOPE ([Report Date].[Time Period].[All].[Last 90 Days]);
THIS = Sum(LastPeriods(90,StrToMember("[Report Date].[Report Date].[Day].&["+CStr(Format(Now(),"yyyyMMdd"))+"]")));
END SCOPE;

它有效(也添加了一项措施来对要验证的级别成员进行计数):

It works (also add a measure to count members of a level to validate):
