Average total Table

Question

Hello,
I have 2 tables in my report..
the first table displaying Gross Income For every business unit yearly
First Table
_____ 2009|2008|2007|2006|2005|
Buss1 |_12_|_18_|_15_|_13_|_10_|
Buss2 |_10_|_13_|_12_|_18_|_19_|
Buss3 |_15_|_10_|_17_|_14_|_11_|
Buss4 |_14_|_12_|_19_|_13_|_18_|
Total _|_51_|_35_|_63_|_58_|_58_|
Now my problem are, creating a second table that displays average total for 3 years
The formula for the average total (from my understanding) are
for 2009 =(Total 2009+total 2008+total 2007)/3
for 2008 =(Total 2008+total 2007+total 2006)/3
for 2007 =(Total 2008+total 2006+total 2005)/3
so the table will be like this
_____________|2009|2008|2007|
Average Total__|_50_|_52_|_60_|
can anyone give some opinion about this..
Thanks..

Hi Nico,
Thanks for the reply, Your suggestion for the filter is apperciated, but my requirement is to make the result dynamic.
I already try what you have suggested, (and it works, but not dynamic)
(FILTER("Sales Facts"."Amount Sold" USING (Time."Year" = '2009'))+FILTER("Sales Facts"."Amount Sold" USING (Time."Year" = '2008'))+FILTER("Sales Facts"."Amount Sold" USING (Time."Year" = '2007')))/3Where this is static..If u understand what I meant..
I tried to use this Filter
(FILTER("Sales Facts"."Amount Sold" USING (Time."Year" = Time."Year" ))+FILTER("Sales Facts"."Amount Sold" USING (Time."Year" = Time."Year"-1 ))+FILTER("Sales Facts"."Amount Sold" USING (Time."Year" = Time."Year"-2 )))/3But according to the link u gave, the expression Time."Year"-1 is not allowed (only measure column allowed)..
And can you explain more on this
FILTER("Sales Facts"."Amount Sold" USING ( cast(Time."Year" as number) > ( Year(current_date) - 3) ))Thanks,
Azzad
