Hello,

May you assist me, please?

SalesAggFinal:

LOAD
YearMonth,
"Group",
Quantity,
TotalPriceBeforVat,
TotalPriceBeforVat/Quantity as unitprice
FROM [lib://DB/SalesAggFinal.qvd]

(qvd);

SalesAggAcc:

LOAD "Group",
YearMonth,
TotalPriceBeforVat, RangeSum(peek('Cumulative') , TotalPriceBeforVat) AS TotalPriceBeforVatCumulative

Resident SalesAggFinal;
exit script

What do I need to do?\
