    Hi sammy339,

    Thank you for reaching out to the Microsoft Fabric Community forum.

     

    create a mapping table first like below

     

    DateSelector = DATATABLE("DateName", STRING, "ColumnIndex", INTEGER,{{"Column1", 1},{"Column2", 2},{"Column3", 3}})

    DAX Measure:

     

    Date Difference = 
    VAR SelectedCol1 = SELECTEDVALUE(DateSelector[DateName])
    VAR SelectedCol2 = SELECTEDVALUE(DateSelector2[DateName])

     

    VAR Date1 = SWITCH(TRUE(),SelectedCol1 = "Column1", 'Projects'[Column1],
            SelectedCol1 = "Column2", 'Projects'[Column2],
            SelectedCol1 = "Column3", 'Projects'[Column3])

     

    VAR Date2 = SWITCH(TRUE(),SelectedCol2 = "Column1", 'Projects'[Column1],
            SelectedCol2 = "Column2", 'Projects'[Column2],
            SelectedCol2 = "Column3", 'Projects'[Column3])

     

    RETURN
    IF(ISBLANK(Date1) || ISBLANK(Date2),BLANK(),DATEDIFF(Date1, Date2, DAY))

     

    I have included the PBIX file that I created using the provided sample data. Kindly review it and confirm whether it aligns with your expectations.

Thank you Dharmendar for replying. I am getting following error when trying to use date difference measure. Can you please upload a sample project.

Error Message :

MdxScript(Model) (4, 21) Calculation error in measure 'Table'[Date Difference]: Column [DateSelector] is part of composite key, but not all columns of the composite key are included in the expression or its dependent expression.
