Differences between last 5 months
Hi @Theriaux ,
I created a sample pbix file(see attachment) for you, please check whether that is what you want. You can create a measure as below:
Difference = VAR _seldate = SELECTEDVALUE ( 'Table'[Date] ) VAR _enddate = EOMONTH ( EDATE ( _seldate, -1 ), 0 ) VAR _startdate = EDATE ( _enddate, -5 ) + 1 VAR _pre5years = SUMX ( FILTER ( ALLSELECTED ( 'Table' ), 'Table'[Date] >= _startdate && 'Table'[Date] <= _enddate ), [Total cases] ) RETURN IF ( ISBLANK ( _pre5years ), BLANK (), [Total cases] - _pre5years )You can refer the following links to get the values for last N months:
Display Last N months data in Power BI
Display Last N Months & Selected Month using Single Date Dimension in Power BI
If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

Also Anonymous , just one small question again if you don't mind. If I would like to calculate the difference between lets say September and April (not the difference between September and the total number of cases from April to August, just september and april itself). How can I achieve that?

Hi Anonymous ,
I updated my sample pbix file(see the attachment), please check if that is what you want... You can create a measure as below to get the difference with the current month value and the value for 5 months ago:
Difference2 = VAR _seldate = SELECTEDVALUE ( 'Table'[Date] ) VAR _enddate = EOMONTH ( EDATE ( _seldate, -1 ), 0 ) VAR _pre5month = SUMX ( FILTER ( ALLSELECTED ( 'Table' ), 'Table'[Date] >= EDATE ( _enddate, -5 ) +1 && 'Table'[Date] <= EDATE ( _enddate, -4 ) ), [Total cases] ) RETURN IF ( ISBLANK ( _pre5month ), BLANK (), [Total cases] - _pre5month )Best Regards
