BI4.0 AOLAP - Sub analysis function

Hi,

Could anyone advise if the sub-anlysis "only" displays the same columns as the analysis that it is linked to in BI4.0 AOLAP?

i.e. I was trying to run an AOLAP report, then create a linked sub-anlysis.....the hope being that the main analysis would say have the default columns, whereas I could perhaps add or subtract a few to the sub-analysis etc. e.g. If I select sales organisation in the main analysis, then select display focused analysis, I dont really need to see sales org again, perhaps I just want to see ship to etc.....

Again, just looking to confirm what sub analysis is or isn't....

Thanks

Ian
