Reporting services 应为MDX表达式。指定了一个空表达式

当我试图在ssrs查询生成器中构建mdx查询时，我收到了这条消息。有什么想法吗？？？？ 错误： 应为MDX表达式。指定了一个空表达式。（Microsoft SQL Server 2008 R2分析服务）这是我的MDX

语法看起来不错，所以我猜@ProductsByCategory就是问题所在

传递给此参数的字符串需要采用集合的形式，因为您使用的是stroset函数。 我通常删除“constrated”参数，因为它强制您列出一组由扭曲的大括号{}括起的元组 如果删除该参数，则可以使用返回集合的MDX表达式，而不是显式指定集合
