OLAP cube and formula
 

Hi,
I created an OLAP cube by data-pivot table report-... from a relational
database. Then I chose "Create offline OLAP cube". The cube was created, but
it doesn't seem possible to add a formula based on the fact fields to the
OLAP cube.

The fact are 'sales' and 'revenues' and I need to see the ratio '=sales /
revenues'. Is it possible at all?? If not - can I buy any update or smth. to
get this functionality? This is a normal functionality for pivot tables. I
don't understand why can I not do this in OLAP cube?

Thanks for your time.
