member property "KEY ID" in SSAS - ssas

Question

I've got a cube, I can fetch all other member properties using CurrentMember.PROPERTIES("property name")
But the property that's named "KEY ID" simply returns that member's key value.
This query gets me KEY of the property:
WITH
MEMBER [x] AS
[Product].[UPC].CurrentMember.PROPERTIES("KEY ID")
select
[x] on COLUMNS,
[Product].[UPC].[UPC] on ROWS
FROM [my_cube]
If pull out KEY ID as a dimension, it gives me KEY ID's correct value.
Like this:
select
[measures].[sales units] on COLUMNS,
[Product].[KEY ID].[KEY ID] on ROWS
FROM [my_cube]
What's more, I was making random changes to my query and found that the gibbery of [Product].[UPC].CurrentMember.PROPERTIES("KEY asdf") gives me value of KEY as well.
I searched MSDN and did a bit googling, but cannot find any documentation saying that "KEY ID" (or "KEY XXXXX") is reserved, or "KEY ID" is interpreted as "KEY". Does anyone know of any explanations?

Answer 1

Here is MSDN documentation concerning properties:

Another way to get the Key as an integer is:
WITH
MEMBER [x] AS
[Product].[UPC].CurrentMember.Properties('key0', TYPED)
select
[x] on COLUMNS,
[Product].[UPC].[UPC] on ROWS
FROM [my_cube]
Unfortunately I'm unable to help with a specific answer to your question but maybe the above helps a little.
