Ssas 如何在MDX中查找层次结构中每个组的总和

在下面的例子中，我想找出每组的总和。是否有人可以更正我的MDX查询以获得GroupCount列所需的结果

with member [GroupCount] as
aggregate([Department].[Department ID].currentmember.parent,
          [Measures].[Pay Frequency])


select {[Department].[Group Name].[all].children*
        [Department].[Department ID].[all].children
       } on rows,
{[Measures].[Pay Frequency],[GroupCount]} on columns
from test

我从上述查询中得到的结果是：

但是，我需要输出为：

是这样的吗

with member [GroupCount] as
(
     [Department].[Group Name].CURRENTMEMBER,
     [Department].[Department ID].[All],
     [Measures].[Pay Frequency]
)
select {[Department].[Group Name].[all].children*
        [Department].[Department ID].[all].children
       } on rows,
{[Measures].[Pay Frequency],[GroupCount]} on  columns
from test;
