Mdx 需要获得维度的所有成员之和减去一个成员

我正在尝试做一个MDX查询，可以告诉我有多少产品在中国以外的国家销售。通过下面的查询，我只能得到每个国家的瓶装水销售量，但不能得到它们的总数。我如何修改查询以获得其总和

SELECT NON EMPTY Except(
   {[Location].[All Places].Children}, 
   {[Location].[China]}
) ON COLUMNS,
  {[Product].[All Products].[Bottled Water].Children} ON ROWS
FROM [Places]
WHERE [Measures].[Units Sold]

---

以下操作应满足您的要求：

WITH 
  SET [countries] as Except( {[Location].[All Places].Children}, {[Location].[China]} )
  MEMBER [measures].[X] as Sum( [countries] , [Measures].[Units Sold] )

SELECT {[Product].[All Products].[Bottled Water].Children} ON ROWS 
FROM [Places] 
WHERE [measures].[x]
