返回特定成员以下的所有级别

Question

在下面我希望返回成员Engineering下面的所有树。
我猜我在滥用IS？
我应该使用membervalue吗？
我认为使用特定成员会更有效？

WITH 
    MEMBER [Measures].[LevelName] AS
        [Employee].[Employee Department].Level.Name
    MEMBER [Measures].[LevelNumber] AS
        [Employee].[Employee Department].Level.Ordinal
SELECT
    {
    FILTER(
        [Employee].[Employee Department].AllMembers,
        [Employee].[Employee Department].[Department] IS 
            [Employee].[Employee Department].[Department].&[Engineering]
        )
    } ON 1,
    {
    [Measures].[LevelName],
    [Measures].[LevelNumber] 
    } ON 0
FROM [Adventure Works] 

这是错误信息：

执行查询...查询 (10, 3) Is 函数需要一个级别 2 参数的表达式。使用了成员表达式。执行 完成

您不需要使用 FILTER 函数来获取属于特定成员的所有子成员。只需这样做：

SELECT
{
    [Employee].[Employee Department].[Department].&[Engineering].CHILDREN
} ON 1,
...

如果您想要特定成员下方的整个树，请使用 DESCENDANTS 函数：

SELECT
{
    DESCENDANTS([Employee].[Employee Department].[Department].&[Engineering],
        [Employee].[Employee Department].[Department], AFTER)
} ON 1,
...
