Rolling sum on Qlik Sense

Hi all,

I need to build a "rolling sum" plot (or table as well), i. e. a sum that month by month runs on the latest 12 months.

More precisely, I have a graph that shows a variable (the number of sold products) month by month.

The other variable I want to show is the sum of sold products on one year up to that month.

The result should be a plot showing (month by month) the units sold in that month (e.g. March 2017) and the units sold on one year that far (e.g. April 2016 - March 2017).

I hope the request is clear.

Any help would be very appreciated.

Thanks, LuigiZ

Re: Rolling sum on Qlik Sense

Tank you agigliotti!

I've read that article, as it was advised earlier by omarbensalem‌, but couldn't transpose it in my case.

I did some try as well, but with no result.

The formula you suggest gives a total, but it's not the right one (it makes a sum but I don't understand the calculus).

So I tried to remove the outest "Sum( Aggr(" and it works fine    (see attached file).

So the right formula, for my case, is:


RangeSum(

               Above( total Sum( {<[PostingDate.autoCalendar.YearMonth] = >} Quantity)

        ,           0, 3)

                    )


This makes a 3 months Rolling sum.


By wrinting 12 instead of 3 I make 12 months rolling sum.


Great thank you to all who contributed.

Re: Rolling sum on Qlik Sense

Sum({<Num_Month = {$(=Max(Num_Month)-1)}, Year = {$(=Max(Year)-1)} >} Units_Sold)

Not a perfected expression cus by default what should be shown?

Current year sales or previous year sales?

And the selection should only happen if Month is selected?

if(getselectedcount(Month)>0,

Sum({<Num_Month = {$(=Max(Num_Month)-1)}, Year = {$(=Max(Year)-1)} >} Units_Sold))

Maybe this would work...? Num month should be a numeric field and year as well.

Re: Rolling sum on Qlik Sense

Hi Aehman,

the first formula you provided works but it gives the same result as:

Sum(Units_Sold)

What I wanted to do, instead, is to create  sum of Units_Sold on the last 12 months, month by month (the so called Rolling sum).

Something like this:

Sum(FROM Date.autoCalendar.MonthsAgo = 12 TO Date.autoCalendar.YearMonth)

But I don't know how to set these two ends of the sum

Thanks

Re: Rolling sum on Qlik Sense

Thanks Beck,

I'm not able to get you proposal: my table has 1 record with Quantity and Date fields, so I have a number in quantity for each day.

I'm looking for a Measure expression to put in the plot.

Thanks again

Re: Rolling sum on Qlik Sense

Complete information.

I created a table in the same app showing the same result of the plot, but in numeric way (both have the same issue).

My plot have

DIMENSION = Date.Auttocalendar.YearMonth

MEASURE = Sum(Quantity)

and it correctly shows me the total number of items sold per each month.

I'm really not able to show the units sold over 1 year:

Oct 2017 to show units sold from Nov,1 2016 to Oct, 31 2017

Nov 2017 to show units sold from Dec, 1 2016 to Nov, 30 2017

Dec 2017 to show units sold from Jan, 1 2017 to Dec, 31 2017

My fields are DATE for the dates and QUANTITY for the number of units

Nov 2017 to show units sold from Dec, 1 2016 to Nov, 30 2017

Dec 2017 to show units sold from Jan, 1 2017 to Dec, 31 2017

You want to how previous year sales upon selection of a particular field or by default?

You can create a Last Year Flag in back end, use that Flag =1 in expression to show the sales of PYTD.

Maybe I'm wrong, this looks like rolling year with month

Can you post a sample data?

Thanks

Re: Rolling sum on Qlik Sense

Create your own master calendar: (it's always better to build ur own calendar, it's a preference thing)

Just copy and paste this:

Let vMinDate=num(MakeDate(2014,12,31));

//Let vMinDate= AddYears(today(),-2);

Let vMaxDate=Today()+30;

NoConcatenate

[D_Calendar_TMP]:

Load date($(vMinDate)+ RowNo()) as [Calendar date]

AutoGenerate $(vMaxDate)-$(vMinDate);

NoConcatenate

[D_Calendar_TMP2]:

Load RowNo() as [%Date SEQ]

Resident D_Calendar_TMP2;

Drop table D_Calendar_TMP, D_Calendar_TMP2;

DONT't change a thing

Then, in your fact table, in which you have the date field; do as follow:

AutoNumber(date(YourDateField, 'DD/MM/YYYY'),'%Date ID') as [%Date ID]


Now: as an expression for ur rolling month:


use this:

sum({<[Calendar date]=,[Month of date]=, [Year of date]=, [%Year month SEQ] = {"> $(= max([%Year month SEQ]) - 12)  <= $(=[%Year month SEQ])"}>}QUANTITY)


and a dimension use :

date([Month end date 2], 'MMM-YYYY')


Now, when you choose a Mars 2017 for example, you'll have:

Re: Rolling sum on Qlik Sense

If you want cumulative rolling: please refer to this:

Calculating rolling n-period totals, averages or other aggregations

and try to use this:

sum( aggr( rangesum( above( sum(QUANTITY),0,12) ),Month))

Re: Rolling sum on Qlik Sense

Or try sthing like:

sum({<Date.Autocalendar.YearMonth=,Date.Autocalendar.Year=,Date.Autocalendar.Month=,Date.Autocalendar.Date=,

Date.Autocalendar.Month={">=$(=addMonths(max(Date.Autocalendar.Date),-12))<=$(=max(Date.Autocalendar.Date))"}>}Quantity)
