Adding a Descendents Query to a Cube

Question

Hi,
I have the following MDX query that I wish to add to a cube:
with member [measures].[descendents test] as
sum
    Descendants ([Date].[Calendar Year],, LEAVES) *
    Descendants ([Date].[Calendar Quarter of Year],, LEAVES) *
    Descendants ([Date].[Calendar Week of Year],, LEAVES) *
    Descendants ([Product].[Category],, LEAVES) *
    Descendants ([Product].[Subcategory],, LEAVES) *
    Descendants ([Product].[Product],, LEAVES)
            ([Measures].[Internet Sales Amount] * [Measures].[Internet Tax Amount])
) / [Measures].[Internet Freight Cost]
select [measures].[descendents test] on columns,
[Date].[Calendar Year].children on rows
from [Adventure Works]
What's the best way to add a descendents query to a cube? I don't think I should include the Calendar Dimension as the cube has multiple Calendar Hierarchies that I want the calculation to use if selected. Essentially the calculation should do the calculation
at the lowest level even when it's rolled up to a higher level.
Any help and direction would be greatly appreciated.

Hi Silverarrows,
What do you mean by "Add query to a cube"? If you want to add the calculation to the cube, then we can add it in the Calculations tab in the cube designer in BIDS. A calculation is nothing but an MDX expression or script which is used to define
a calculated member, a named set, or a scoped assignment in a cube. For the detail information about how to do it, please refer to the links below.
