Need some help here.
I have this script for Cumulative Summary of NetRoomRevenueWithoutVat column by Year.
I would like to add another or two variable let's say by Year and By Agency and By Location (could be character or numeric).
Thank you in advance
If( Row() == 1 | Lag( :Year ) != :Year,
:NetRoomRevenueWithOutVat,
Lag( :CumSumByYear ) + :NetRoomRevenueWithOutVat
)
