MDX Query WHERE Dimension = another Dimension - ssas

Question

If I have two Dimensions: Origin and Destination how can I count the number of times Origin = Destination?
SELECT [Location] ON COLUMNS
FROM [DELIVERIES]
WHERE ( [Origin] = [Destination] )
[Origin] = [Destination] obviously isnt the answer...
The following code produces the correct result:
SELECT
SUM(Transfers) AS Same_Skill_Transfers
FROM (
SELECT
CONVERT(varchar(30),"[From VQ].[LOB].[LOB].[MEMBER_CAPTION]") As From_VQ,
CONVERT(varchar(30),"[To VQ].[LOB].[LOB].[MEMBER_CAPTION]") As To_VQ,
CONVERT(integer,"[Measures].[Transfers]") As Transfers
FROM
OPENQUERY(TRANSFERS,'
SELECT
{[Measures].[Transfers]} ON COLUMNS,
Filter(NonEmptyCrossjoin( [From VQ].[LOB].Members, [To VQ].[LOB].Members),
[From VQ].[LOB].[LOB].[Life Cycle].Properties(''Caption'') = [To VQ].[LOB].[LOB].[Life Cycle].Properties(''Caption'')
) ON 1
FROM
[Transfers]
WHERE (
[Date].[Date Hierarchy].[Month].[July 2014],
[From VQ].[Hierarchy].[AOB].[Consumer],
[From Agent].[Employee Id].&[612117]
)
')
) A
WHERE
To_VQ = From_VQ
Lets say I have a [FROM_VQ].[LOB] = "BOTH" and I want to include in the SUM when [FROM_VQ].[LOB] = "Both" and [TO_VQ].[LOB] is either A or B?

Your question is missing some info, but I'll take a stab and then update once you provide more info. I'm assuming that there are two dimensions, origin and destination, and that each of these dimensions have a location attribute.
In general, you can use a filter statement for this. If your location attribute has the same key in each dimension, you can do this:
select [Origin].[Location].children on 0,
Filter(NonEmptyCrossjoin( [Origin].[Location].Children, [Destination].[Location].Children),
[Origin].[Location].Properties('Key') = [Destination].[Location].Properties('Key')
) on 1 from [DELIVERIES]
If the keys aren't the same, but the label you see for the field is you can switch Key for Caption.
Here's an example where someone did this with dates.
