MDX 计算成员 SUM 与 OR

Question

我继承了一些使用计算成员和求和函数的 mdx 代码。我需要使用 SUM but 和 OR（union？）集创建一个新成员。我尝试了各种语法，但它们都出错了。

我的代码如下：

-- uses this date filter
set [as_of_month] as {strtomember("[Date].[Year -  Month].[Month].&[" + cstr(format(cdate("Jul 2019"),"yyyy-MM")) + "-01T00:00:00]")}

-- member 1
member [SIONLY_MTH] as sum([as_of_month] * [Incident Details].[Is SI].[Is SI], [Measures].[Environment Impact Count])

-- member 2

member [MajorNC_Month] as  sum([as_of_month] * 
                        [Impact].[Impact].&[3] * 
                        [Non Compliance].[Non Compliance Type].&[Major non-compliance], 
                        [Measures].[Non Compliance Count]) + 0

-- I need a new member which is an OR of the previous 2, ie, count of
-- SI_ONLYMONTH or [MajorNC_Month] filtered by [as_of_month]

member [LegalSI_EnvSI_Month] as SUM([as_of_month] * {[Incident Details].[Is SI].[Is SI] , [Non Compliance].[Non Compliance Type].&[Major non-compliance]}
, [Measures].[Environment Impact Count]) + 0

最后一个 sum 函数中的设置不起作用，它 returns #Error.

有谁知道如何使用联合集作为 mdx 中 SUM 函数的参数？

谢谢

你的问题基本上涉及维度和层次的概念

试试这个

总和( { ([as_of_month] * [事件详情].[是 SI].[是 SI][影响].[影响].defaultmember[不合规].[不合规类型].defaultmember), ([as_of_month] * [事件详情].[是 SI].defaultmember*[影响].[影响].&[3]*[不合规].[不合规类型].&[重大不合规遵守]） } , [措施].[环境影响计数])

编辑：包括对上述查询的工作原理和原因的解释。在您的问题中，您有两组具有不同的层次结构。所以你必须平衡它们。让我们来看看你的第一组

sum([as_of_month] * [Incident Details].[Is SI].[Is SI], [Measures].[Environment Impact Count]) This doesnt explicitly include "[Impact].[Impact]" however before executing SSAS takes the liberty to include [Impact].[Impact].defaultmember in the query. Based on this fact I balanced both of your sets by expicitly including the default members of attribute hierarchies that were orignally not part of your Set.

接下来我将它们封装在“()”中以表明它们是一个更大的元组Set.Then这两个元组都封装在“{}”中，如下所示“{(tuple1),(tuple2) }"
