I am a begginer is useing Power BI and DAX. I need to substruct within one column. The column is called "DR" and has only DR08 and DR07, but this will be growing each month, so next month I will have DR09. I need to subtract every month the current one (so it will be DR09) and DR08, then in September, it will be DR10 and DR09. Is there a way to write a macro (or other solution) that will always take the current one and substruct from the previous one? Each dR comes from different file, and Forecast table has all them append.
Solved! Go to Solution.
@Anonymous I would recommend unpivoting those columns. Then you can construct a measure that finds the maximum value in the Attribute column and subtract it from the previous latest one.

This worked great. Thank you!
