Need help with accumulation formula

[#1]

Hi Qlik-Experts!

I need help with a certain accumulation formula.

I have to accumulate booking amounts over the years in a pivot table. With some search in the community I found a formula which works when the last dimension in the pivot table is the booking year, but not when other dimensions are placed after the year.

Please find a simplified sample of my problem attached. The formula I am using right now is:

= if(rowno(),rangesum(sum(Amount  ) , above(sum(Amount) ,1,rowno())),sum( Amount ) )

And I have problems to adapt it in a way, that it is somehow fixed to the year dimension.

Any help is much appreciated!

Hi,

aggregate the whole expression per Year field:

 =aggr( if(rowno(),rangesum(sum(Amount  ) , above( sum(Amount) ,1,rowno())),sum( Amount ) ) ,Year) 

Hope that helps!

Okay, works so far for aggregation over the years no matter which dimension is else in the pivot table.

Thank you so far!

Now I figured out I need to change  the description of the requirement a bit.

I need to aggregate over the years but only for the dimension which come after the year.

So if the original data looks like this:

%Key1	Year	SalesRep	Amount
A	2008	Mary	100
A	2009	Mary	200
B	2008	Joe	500
B	2009	Joe	400

I would need the output like this (accumulated over the year but still a drilldown through the dimensions in the pivot)

Year  SalesRep  Amount

2008  Mary        100

2009  Mary        300

2008  Joe          500

2009  Joe          900

The expression from Steve gives me:

Year	SalesRep	Amount
2008	Mary	600
2009	Mary	1200

Hi,

i was unable to make the requested chart wthout modify the data a bit. The change is that every row has unique %Key1 field based on Year&SalesRep combination. The modify table look like this bolow:

%Key1	Year	SalesRep	Amount
A	2008	Mary	100
B	2008	Joe	500
C	2009	Mary	200
D	2009	Joe	400

And the expression is:

aggr( rangesum( sum(Amount), above(sum(Amount),1,rowno())) ,%Key1)

Also the sort of the SalesRep must be on %Key1 field.

With this changes the result table is:

If no unique key is availabe in the datasource you can always use the Autonumber number function to make unique key based on a field combination.

Hope this helps!

Hello,

According to your requirement, the following should work:

RangeSum(Above(Sum(Amount), 0, RowNo()))
