    qliksense set analysis

    avneet taneja

      hi

       

      I am struck with set analysis. I know there are many post but not able to figure out

       

      I want to calculate YTD

      Sales Last fiscal year/ sales last YTD

       

      I have a date column and have generated Fiscal calender also.

       

      Please help

          Don't panic, set expressions seems difficult at first sight, but then you'll love working with them.

           

          Let's suppose you have a date field (you don't have to create variables); only a date field will do the job.

           

          And let's suppose you've created a calendar in your script so you have Year,Month, Quarter and Week fields

           

          YTD: if we select 12/04/2016: YTD will return our measure from 01/01/2016 to 12/04/2016

          How we do that?

           

          Suppose our measure is : sum(Sales)

           

          1)First changes: sum({<date=,Year=,Month=,Quarter=>}Sales)

           

          We add these to force Qlik to not take into consideration our selection of date for example.

          Let me explain in better words, if you don't write the "date=" and select the date 12/04/2016; Qlik will filter all the data to that selected point and then return the sum(Sales) for the day 12/04/2016.

          To prohibit this, we must write the date=.

           

          2) Second change: sum({<date=,Year=,Month=,Quarter=, date={">=$(=YearStart(Max(date)))<=$(=Max(date))"}>}Sales)

           

          Let explain this : date={">=$(=YearStart(Max(date)))<=$(=Max(date))"}

           

          We want to work from date=01/01/2016 to the selected date=12/04/2016 right?

          So we're working with the field :

          a) date={    }

          b) Now we wanna this date to be <=selected date which is max(date) ;

          max(date) is a function so it needs an "=" sign:

          =max(date)

          when we have a '=' we add the $ (before each calculation) : $(=max(date) ) => this is 12/04/2016

          Now we add the <= so we'll have :  <=$(=max(date) )


          for the second part, we want our date to be >=01/01/2016 which is the start of the year:

          a) same approach, we use the YearStart function that returns the start of the selected year: >=$(=YearStart(Max(date)))


          Now our expression is : from : date={    }

          to : date={>=$(=YearStart(Max(date)))<=$(=Max(date))}



          Now, in a set expression, if we wanna work with the year 2016 for example which is numeric: we call it without quotes:

          Year={2016}

          If we wanna focus on a country, Tunisia for example which is a string: we call it with quotes

          Country={'Tunisia'}

           

          In our case, we focusing on a range of dates created by an expression, so we surround it by double quotes:

           

          date={">=$(=YearStart(Max(date)))<=$(=Max(date))"}


          Final expression for YTD:


          sum({<date=,Year=,Month=,Quarter=, date={">=$(=YearStart(Max(date)))<=$(=Max(date))"}>}Sales)


          Same approach for MTD:

          sum({<date=,Year=,Month=,Quarter=, date={">=$(=MonthStart(Max(date)))<=$(=Max(date))"}>}Sales)


          Hope this helps,

          Omar,

            could you attach a sample app with mock data showing what are you trying to achieve ?

              Hi Avneet,

               

              Make two indicators called _indLastFiscalYTD and _indLastYTD. Give them an 1 when it is YTD. Then add this formula.

               

              Sum({$< _indLastFiscalYTD = {1} >} [Sales Last fiscal year]) / Sum({$< _indLastYTD = {1} >} [sales last YTD])
