how to avoid cross join in analysis studio

[kennyyeungkw]

Something about using analysis studio

I have a cube about 1GB.
crosstab information:
Column : Year - month - shipment_type
Row : For user selection


The performance of drag 1 dimension is fine .within 10 second.

But when i drag more than 1 dimension into the row ,the report become slower and slower .

Currently ,I have a dimension with more than 10000 member within one level (which like order no ,user dont want to be grouped)
..
When drag this to the row ,the report become extremely slow
I guess it is because of the cross job of 2 dimensional ,it there any solution ?
