You can retrieve user-defined member properties using either the PROPERTIES keyword or the Properties function.
Using the PROPERTIES Keyword to Retrieve User-Defined Member Properties
The syntax that retrieves user-defined member properties is similar to that used to retrieve intrinsic level member properties, as shown in the following syntax:
DIMENSION PROPERTIES [Dimension.]Level.<Custom_Member_Property>
The PROPERTIES keyword appears after the set expression of the axis specification. For example, the following MDX query the PROPERTIES keyword retrieves the List Price and Dealer Price user-defined member properties and appears after the set expression that identifies the products sold in January:
SELECT
CROSSJOIN([Ship Date].[Calendar].[Calendar Year].Members,
[Measures].[Sales Amount]) ON COLUMNS,
NON EMPTY Product.Product.MEMBERS
DIMENSION PROPERTIES
Product.Product.[List Price],
Product.Product.[Dealer Price] ON ROWS
FROM [Adventure Works]
WHERE ([Date].[Month of Year].[January])
Using the Properties Function to Retrieve User-Defined Member Properties
Alternatively, you can access custom member properties with the Properties function. For example, the following MDX query uses the WITH keyword to create a calculated member consisting of the List Price member property:
WITH
MEMBER [Measures].[Product List Price] AS
[Product].[Product].CurrentMember.Properties("List Price")
SELECT
[Measures].[Product List Price] on COLUMNS,
[Product].[Product].MEMBERS ON Rows
FROM [Adventure Works]
