Pivot table using Python facing issue - Index variables are not visible

I tried to pivot a table with aggregate function sum in python. After running python script in power bi I am not able to see index columns which i used to group by. But if I am trying to execute this code in python it's working perfectly by displaying index columns.

 

Here below my code;

 

import pandas as pd

pivotset = dataset.pivot_table(index=['movieID','user'], values=['Rating'], aggfunc='sum')

print(pivotset)

 

         Result in Python is:

 

movieID user             Rating
1             Ali                5
               Ganesh         5
              Jayaram         2
              Kevin             1
              Mithun          3
              Musthafa       3
              Shafi              4
2            Jack               5
              Sasi               4
              Suresh 3

But if I am trying to do same in power bi the index variables are not displaying. Please help to find this.

 

 Rating
    5
    5
    2
    1
    3

 

The input dataset csv is below

 

movieID,user,Rating
1,Ganesh,5
1,Mithun,3
2,Sasi,4
1,Musthafa,3
2,Suresh,3
1,Shafi,4
1,Kevin,1
2,Jack,5
1,Jayaram,2
1,Ali,5

Please help me to find why the index variables are disappearing in power bi

Re: Pivot table using Python facing issue - Index variables are not visible

@pg-gopinathan ,

 

Based on my test, I'm afraid power bi doesn't support index columns in pandas table. As a workaround, you can achieve the same result by using "Pivot" and "Unpivot" in power query.

 

Firstly click "movieID" and "user" column, click transform-> Pivot Columns, select "Rating" as value, sum as  aggregation, you will achieve table like below:

Secondly, click on column "1" and "2" then click "Unpivot Columns":

After reordering the columns and renaming the column headers, you will achieve the result:
