Ranking Function in WEBI?

Hi Experts,

I have a weird requirement in WEBI. i have three tables it contains Dimension and Measure.

Now my requirement is if its a Rank one then i need to put these record into one table after that if its a Rank 2 then i need to display only second record into another table. Whenever i am applying Rank 2 it is bringing two records i.e., Rank 1 and Rank 2 but i need to get only second record (i.e., Rank 2 record).

Is there a way to achieve this?

Thanks

Sudha

    • Hi Sudha,

      I did the below and it works (with one minor issue that I didn't spend time on) for your requirement.

      • Create variable v_Rank = Rank([Amount])
      • Create variable v_Rank1 =If([v_Rank]=1) Then 1 Else 0 (This is used as a flag)
      • Create variable v_Rank2 =If([v_Rank]=2) Then 1 Else 0 (This is used as a flag)
      • Create variable Select a Rank =1 (We'll create Input Control on this object, so, 1 becomes default selection)
      • Create a Input Control -> Single Value -> Entry Field and you'll see that the Default value(s) is 1

      • Now, you'll see that Select a Rank value will be equal to the value you enter in the input control.
      • Create a final variable v_Displayed Rank =If([Select a Rank]=1) Then [Cust ID] Where ([v_Rank1]=1) ElseIf([Select a Rank]=2) Then [Cust ID] Where ([v_Rank2]=1)
      • Add v_Displayed Rank to the table and filter on it as v_Displayed Rank Is Not Null.
      • Now when you enter 1 in the filter and click OK, you'll see Rank1 row is displayed and when you enter 2 in the filter and click OK, you'll see Rank2 is displayed.

      Note: As a test, add all the variables we created to the table including Cust ID & Amount to see what each variable does.

      That's it, try if its working fine. Let me know if this helps and/or if you have any questions.

      Thanks,
