Calculating the difference between two columns

[akendrick15]

I am wanting to show the difference between the columns for our week-over-week comparison. It could be on a drill-through page or another visual.

Any help is greatly appreciated.

Hi @akendrick15 ,

Try formula like below:

According to the information you provided, the external filter conditions are the category corresponding to the row and the date corresponding to the column, respectively. So you can use the alexcept function to keep the filter conditions for both columns.

Cus_Ter =
CALCULATE (
    SUM ( 'Table'[Date] ),
    ALLEXCEPT ( 'Table', 'Table'[Customer], 'Table'[Date] )
)
    - CALCULATE (
        SUM ( 'Table'[Date] ),
        ALLEXCEPT ( 'Table', 'Table'[Terminal], 'Table'[Date] )
    )

If the problem is still not resolved, please provide detailed error information and test data. Looking forward to your reply.

Best Regards,
Henry
