How to hide a member?

I have a dimension named Products with the following hierarchy:

Type
Sub Type
Product

Due to requirements I want that a particular product, whose name is, say, "XYZ" should not be displayed when the user drills down to the lowest level i.e. the Product level.

I tried playing with the Advanced Properties tab but could not make any progress and thus will be grateful for help.

Thanks.

Read throught the "Member Groups" topic in the books online - this might be one approach, depending upon your structure.

Best,

Bill
