I have attached the MDX query below.  Also,  is there a way to do this without the MDX query or SSRS parameters and just remove 'unknown' as a member?

Hi

To remove it witout using query you would have to have clean data which is not realistic if the field is not mandatory.

Sometimes unknown value is valid and you can remove using non empty (with side affects) or except function which will explicitly remove it from the query.

Below is link to except function

Remeber that unknown can be in two forms .unknownmember or just empty string ''

Hope that gives you some more information to play with it.

Okay,  I have made a grand attempt at this with the syntax, worked through several issues then received:

"The xxx hierarchy already appears in the Axis1 axis"

Any thoughts

You cannot duplicate the same hierarchy (dimension attribute).

So if you use [product].[category] it cannot exist more than once. (eg cannot be both in on rows and where).
