Assuming that by different object you mean in another cube? In 4.0 this
cannot be done from inside NAV. Using either BI Development Studio for SQL
2005 or Analysis Manager for SQL 2000 you can go and add another Calculated
measure to a Virtual Cube that contains data from both underlying cubes from
which you want to do calculations between. This, however, will no be
preserved if you execute the configurator from inside NAV meaning that you
will have to recreate the calculation each time this is done.
In BA for 5.0 we have added this functionality. This means that you can add
calculations in virtual cubes and this will be preservede each time the
configurator is run
Hope this was helpfull
