Problem with Aggregation function

[#1]

Hi Experts ,

I am trying to do this Aggr :

=Max(Aggr(Sum({$<Year ={">=$(=(max(Year ))-$(V_YearBack)) <=$(=(max(Year) ))"}>} Sales_EUR),Week_Extract))/1000 

But this ... doesn't work !!

Any help is welcome

Thanks

Try something like this

=Max(Aggr(Sum({$<Year ={">=$(=(max(Year ))-V_YearBack) <=$(=(max(Year) ))"}>} Sales_EUR),Week_Extract))/1000
