Check the settings of Member Keys Unique and Member Names Unique properties
in the advanced tab on the level. If this doesn't work, what error are you
seeing during processing?

You might also try creating what look like pure star schema views on top of
your snowflakes.

Hi, Matt,


The message is still"Unable to brouse to dimension'New Dimesion'. The
dimension cannot be displayed until a cube that contains it has been
processed", even after I checked the "ordering & uniqueness of
members" option in the select advanced option window.

Kevin,

Say, I have a employee dimension for some fact table. Link to the
employee dimension, say I has a secondary dimension called:
officebuilding, which I have to model it as many-to-many to the
employee dimension, so I have to have a link table called: emp_office
table. I don't know how can I build a view to avoid them.

Thanks so much for all the inputs.


Eugene

This message means that the AS UI is not able to simulate the data contained
in the dimension using a local cube. This may be because the estimated size
of the dimension is large or possibly because it uses a feature not
supported in local cubes. If you process a cube containing this dimension
in an unmodified state (no hidden or disabled levels or calculated members
added) then you should be able to browse.

Matt,


Thanks for the hint. I do see the data which was
processed even though it said: unable to prcess. It
proves to me that it can handle many-to-many
relationship in the dimensional parts. I do appreciate
it.


Eugene
