MDX聚合在较低级别

Question

我需要在较高级别上使用过滤器对较低级别的成员进行聚合。 报告每年在一个特定月份过滤销售。 这是FoodMart数据库和产品维度的示例，其级别为：

1. [产品系列]
2. [产品部]

MDX：

WITH
MEMBER [Measures].[Unit Sales Calculated] AS
    Aggregate(
        Intersect(
            Descendants(
                [Product].CurrentMember,
                [Product].[Product Department],
                SELF
            ),
            [Filtered Product Department]
        ),
        [Measures].[Unit Sales]
    )
SET [Filtered Product Department] AS
Except(
    [Product].[Product Department].Members,
    [Product].[Drink].[Alcoholic Beverages]
)
SELECT
 NON EMPTY [Measures].[Unit Sales Calculated] ON COLUMNS,
 NON EMPTY [Product].[Product Family].Members) ON ROWS
FROM [Sales]

此解决方案有效但性能相当差。 是否有更好的方式来编写此查询？
