I have tried changing my year column 'ERPYear' to a date format, and attempted PREVIOUSYEAR, and SAMPLEPERIODLASTYEAR but I cant seem to get anything to work!
Help would be greatly appreciated - thanks!
Hi d4rren
You can create a Column as below.
Column = VAR __previousYear = 'Table'[ERPYear] - 1 VAR __previousYearNumber = CALCULATE( SUM( 'Table'[Number] ), ALLEXCEPT( 'Table', 'Table'[ASGSCode] ), 'Table'[ERPYear] = __previousYear ) RETURN IF( NOT ISBLANK( __previousYearNumber ), 'Table'[Number] - __previousYearNumber )Best Regards,

LinkedInTry this with a separate year table
diff from last year calculate(sum(Table[Number ]),filter(Year[Year]=max(Year[Year]))) - calculate(sum(Table[Number ]),filter(Year[Year]=max(Year[Year])-1)) or divide(calculate(sum(Table[Number ]),filter(Year[Year]=max(Year[Year]))), calculate(sum(Table[Number ]),filter(Year[Year]=max(Year[Year])-1)) )Or try these with dates and date calendar
YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(('Date'[Date]),"12/31")) This Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD((ENDOFYEAR('Date'[Date])),"12/31")) Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31")) Last YTD complete Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31")) Last to last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-2,Year),"12/31")) Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
