2	bbbb	01/06/2017	3339.98	1457068

Date linked to a Date master calendar table, 

Master Calendar = ADDCOLUMNS ( CALENDAR (DATE(2017,01,01), DATE(2018,12,31)), "DateAsInteger", FORMAT ( [Date], "YYYYMMDD" ), "Year", YEAR ( [Date] ), "MonthNo", FORMAT ( [Date], "MM" ), "YearMonthNo", FORMAT ( [Date], "YYYY/MM" ), "YearMonth", FORMAT ( [Date], "YYYY/mmm" ), "MonthShort", FORMAT ( [Date], "mmm" ), "MonthLong", FORMAT ( [Date], "mmmm" ), "WeekNo", WEEKNUM([Date]), "WeekDay", FORMAT ( [Date], "dddd" ), "WeekDayShort", FORMAT ( [Date], "dddd" ), "Quarter", "Q" & FORMAT ( [Date], "Q" ), "YearQuarter", FORMAT ( [Date], "YYYY" ) & "/Q" & FORMAT ( [Date], "Q" ), "Month Year", FORMAT ( [Date], "mmm") & " - " & FORMAT( [Date], "yy"))

Hi @KH11NDR,

I'm not very clear about your logic, could you describe your requirement in more details.

I would appreciate it if you could share your expected output.

Best Regards,

I've tried PREVIOUSMONTH, still don't work.

PM **bleep** Revenue Submitted = CALCULATE([Sum of Cumulative Revenue Submitted],PREVIOUSMONTH('Calc Numbers'[Date]))

Hi @KH11NDR,

I have made a test with your logic. 

I created a two calculated columns below and get the output.

last month revenue = CALCULATE(SUM('Table'[Previous Revenue Submitted (£)]),PREVIOUSMONTH('Master Calendar'[Date]))

Column = 'Table'[Commercial  Total]-[last month revenue]

If you still need help, please share a dummy pbix file which can reproduce the scenario, so that we can help further investigate on it? You can upload it to OneDrive or Dropbox and post the link here. Do mask sensitive data before uploading.)
