| Check the settings of Member Keys Unique and Member Names Unique properties in the advanced tab on the level.

| 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.

| 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 Carroll -- This posting is provided "AS IS" with no warranties, and confers no rights.

| 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.
