Hi i Have a straight table with 4 dimensions Sales Area, Sales Market, Company Country and Company Name.
In expressions i have sum(Sales) and it's ok
for second i want to calculate slope for 3 last months.
I use
linest_m(aggr(
sum({1<[Created Year Month] = {$(=vCreated_YearMonths)} >} Sales)
,
MonthsRange,CompanyQL,[Sales Area], [Sales Market],CompanyCountryNameQL)
,MonthsRange)
where Moths Range is (1,2,3)
and I always get 0, which is not true.
Regards
Łukasz
