      Hi,

       

      I have data like this

       

      region  sales

      A           3

      B          4

      C          8

      A          7

      B          2

      A          4

       

       

      can I create a calculated field which store region wise total sales. something like sum(sales) group by region.

       

      one solution that I found is creating an aggregate table which store region and sum(sales) group by region (using custom sql)

       

      is there any other way to get data like this.is there any solution like  aggr(sum(sales),region)

          Sounds like you could create a calculated field with WINDOW_SUM(SUM([Sales])).

          Then you would just need to make sure you include the [Region] dimension in your view in the Rows or Columns shelf.

           

          The calculated field will generate a Table Calculation, for which you can control the field(s) used to group the "windows."

           

          Good luck

            Hello, Philip.

             

            I've just faced the same problem - I need to aggregate some measures across the dimension that is not used in the view.

            When I used QlikView earlier there was a powerfull function AGGR(avg(measure), dimention1, dimention2..), but I couldn't find anything simmilar in the Tableau.

             

            Did you solve this problem already?

              Hi Anton,

               

              Did you try custom sql?

               

              Actually I have tried the function you mentioned for Qlikview.But in Tableau we don't have any function similar to that.But Tableau provide a feature called table calculations using that you can aggregate measures used in view.But for that dimensions should be there in the view.

               

              Regards,

              Philip
