Hey,
I'm currently having an issue in Qlik Sense.
I'm calculating YTD for a certain Sales Item and it works using the following Expression:
SUM(aggr(rangesum(above(sum( {$<MonthYear>} InvoiceNetSalesTotal),0,12)),YearId,MonthYear))
So in my current table for each MonthYear (e.g."jan 2016") I have a full accumulation of my Net Sales.
Now the question is how do you get the numbers for the previous year?
I've tried using:
SUM(aggr(rangesum(above(sum( {$<MonthYear>} InvoiceNetSalesTotal),12,12)),YearId,MonthYear))
But I can't seem to cross the the aggregation limit of YearId.
So my table should look like:
YearMonth: YTD Current Year: YTD Prev Year:
Jan 2016 (Sales for Jan 2016) (Sales for Jan 2015)
Feb 2016 (Sales for Jan + Feb 2016) (Sales for Jan + Feb 2015)
March 2016 (Sales for Jan + Feb + March 2016) (Sales for Jan + Feb + March 2015)
April 2016 (Sales for Jan + Feb + March + April 2016) (Sales for Jan + Feb + March + April 2015)
