# Power bi sum group by multiple columns

Here we will see two examples on Power bi sum group by multiple columns and Power bi sum group by two columns.

## How power bi sum group by multiple columns

Here we will see Power bi sum and group by multiple columns in power bi.

Here is the sample data we are going to use to solve this problem.

Here we will combine column1 by commas and sum the column2 based on column 3. So, it will show A,B,C(column1) 114(column2) XX(column3)

For this, we will create a calculated table by using Power Bi Dax.

• To create a new table, Click on the Modelling -> New table.
• Then write the DAX formula:
``````Combined =
SUMMARIZE (
'Table',
'Table'[Column3],
"Column1", CONCATENATEX ( 'Table', 'Table'[Column1], "," ),
"Column2", SUM ( 'Table'[Column2] )
)``````

In the below screenshot, you can see the power bi sum group by multiple columns.
