CumSum with more than one variable

[#1]

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

)

If the table is adequately sorted, I think this formula could work:

If(Row() == 1 | Lag(Eval List({:Year, :Agency, :Location})) != Eval List({:Year, :Agency, :Location}),

    :NetRoomRevenueWithOutVat,

    Lag(:CumSumByYear) + :NetRoomRevenueWithOutVat

)

Thank you Michael! Would this help? michael@jmp

It might. But what the optimal sorting would look like depends on the structure/hierarchy of your data. Only you can tell.

Btw, I'm not Michael...
