Cube partition question

Dear All,

I have tried to partition a cube in my dev system (deleted the data first) on 0CALMONTH. When I try to activate the cube, it is failing (telling me it cannot activate the cube as 0CALMONTH is included in other cubes which have data)

I try to rollback my change (remove the parittion) - and guess what - I get the same errors --> I cannot activate my cube anymore!!!

So, I have 2 questions:

1 - I have understood that the cube can be partitioned if it has no data, but it should not be linked to other cubes

2 - How can I rollback my change?

Any help highly appreciated

Thanks

Ioan
