Find difference in 2 columns

[Rana]

I have a Matrix in PowerBI which is showing data for 2 months (month is a string not a date column like Aug, Sept). Matrix shows me Total for both months, instead of Sum i need the difference (reduction or addition) between 2 months. Is it doable if I dont have a date field?

Hi Rana, this is definitely acheivable through the Power BI Desktop, but not in the Service. The exact solution depends how your data is modelled. If you've got two separate fields (one named Aug and one named Sept) then you can just create a calculation that does [Sept]-[Aug]. If its a field called [Month] with values in it for Aug and Sept you'd need to do a bit more DAX work to create a calculation that filters down to just Aug or Sept's data and subtracts those.

If you can post details of your data (or even a sample pbix file) that would help greatly!

Thanks
