SSRS MDX 数据集需要动态字段源，有解决方法吗？答案

【问题描述】：

我有以下有效的 MDX 查询。问题出在 TOPCOUNT 中，我在其中使用 case 语句来计算出我要计算的内容。

INVESTOR、ADVISER 和 ADVISERGROUP 实际上都是同一个维度，链接到事实表中的不同字段，即对于 Adviser，它将是 Entity.IDKey -> Fact.AdviserKey 或对于 Investor，它的 Entity.IDKey -> Fact.InvestorKey

所以问题是所有将返回相同的字段名称，[ID KEY] 但将有不同的位置，即数据集字段源定义需要不同。

在 SSRS 中，它仅适用于一种情况，即它在设计时运行的情况，而其他情况则返回错误。有没有办法解决这个问题？

【解决方案1】：

您将@UserTypeKey 作为参数。因此，您可以根据此参数在报告中进行定位。

当您想根据名称进行过滤并且不想仅为该名称创建另一个数据集时，您还可以添加另一个计算成员。

MEMBER [Measures].[UserTypeKeyName] AS [Dim User Type].[User Type Key].CurrentMember.NAME
