Transformer Based YTD Growth

[damienm]

Dear All,
I currently have a cube for which has fiscal periods and I want to use the built in cals % Growth but aganist the two measures is this possible?

i.e.
                     Revenue    Budget  % Growth
Brand x            YTD         YTD       ???????

Can I just drag % growth? and it will automatic cal aganist revenue vs budget?  If this is not possible what would be the query expression to do this, to make it more harder, I also have current month two in my nested cross tab for which I need to do the same cal.

Sorry maybe a stupid question but new to cognos and need all the help I can get! ;D
