    Hi Anonymous ,

     

    Try this formula. 'Table' is data table and 'date' is date table. I create a year column in the date table.

    Measure 2 = CALCULATE(SUM('Table'[value]),FILTER('Table',YEAR('Table'[date])=SELECTEDVALUE('date'[year])-1))

     

     

    Best Regards,

    Jay

Hi,

 

Continuous dates are required for all time intelligence calculations. Kindly use the date or calendar table to pass date.

 

Appreciate a Kudos! 🙂
If this helps and resolves the issue, please mark it as a Solution! 🙂

    nvprasad , You need to use a date table in all such cases.

    refer example

    YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD('Date'[Date],"12/31"))
Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31"))
This year Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR('Date'[Date]),"12/31"))
Last year 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 :radacad sqlbi My Video Series Appreciate your Kudos.

      Hi amitchandak 

       

      Dim_Time is my date table. Can you see something wrong with it? What should I check on it?

       

       

      I converted the DAX formulas to pass Dim_Time and not Dim_AccountingPeriod since Dim_Time has continuous dates, but I get the following:

      Hi amitchandak 

       

      I used these two of your suggestions for Last Year Sales, but they dont work.

       

      Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))

      Last year Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31"))

       

      What does "12/31" mean? the syntax seems wrong. Visual studio gives an error when used verbatim.

    Hi nvprasad

    I converted the DAX formulas to pass Dim_Time and not Dim_AccountingPeriod since Dim_Time has continuous dates, but I get the following:

     

     

    on the Dim_Time table there are multiple companies/systems which has their own continuous set of dates - could this be an issue? In case it had an issue with multiple entries of a specific date (eg 1/1/2001 for company a, company b and company c), I deleted the other companies so that there is eg on one 1/1/2001 in the Dim_Time table. But that did not solve my problem.
