I want to make the following calculation in Qlik. Do you recommend to do this in the script or front end?
(Value_T + Value_T-1)/2/12*multiplier_T
This calculation has to be done when ID and client in Period T and T-1 are equal. And if there is no comparable combination in the previous period the Value has to be set at 0.
I want that the calculation restarts every year. Therefor I am using the following formula:
Rangesum(Above((Sum(Value) + Above(Sum(Value)))/2/12*Multiplier,0,rowno())),
Date, (Date Month, (Numeric, Ascending))))
Thanks in advance
