    Grouping Dimensions

      Hi,

       

      I'm looking to group a dimension using a calculated field. I'm having trouble with the lF statement.

      [Group] Dimension Contains

      Group1

      Group2

      Group3

      Group4

      Group5

      NULLs (Blanks)

       

      I need to make up (3) Classes.

      Class A Contains "Group1"

      Class B Contains "Group2"

      Class C Contains "Group3, Group5 and NULLs"

       

      (Note that Group4 is not part of any Class)

       

      Here is my Calcultated field IF Statement:

      IF [Group] = "Group1" THEN "Class A"

      ELSEIF

      [Group] = "Group2 THEN "Class B"

      ELSEIF

      [Group] ="Group3 AND [Group]="Group5" AND ISNULL([GROUP]) THEN "Class C"

      END

       

      I'm not sure what I'm doing wrong.

       

      Thanks for your help.

      Mike.

          What are the symptoms of the problem, i.e. works but messes up classes, doesn't work at all, etc.?

          To start with, it looks like the condition

          [Group] ="Group3 AND [Group]="Group5"

          can never be true, as it means that the item belongs to both Group3 and Group5 at the same time. It probably should be

          [Group] ="Group3 OR [Group]="Group5"

           

          Also, Group4 rows will be automatically placed into NULL class, as you didn't specify how to handle them via ELSE.

            Hi Mike,

             

            Similar to what Dimitri said, but the calculation could be similar to the following:

             

            IF [Group] = "Group1" THEN "Class A"

            ELSEIF

            [Group] = "Group2 THEN "Class B"

            ELSEIF

            [Group] ="Group3" then "Class C"

            elseif

            [Group]="Group5" then "Class C"

            elseif

            [Group]="Group4" then "No Class"

             

            END
