Dynamic 2 Date Columns Difference
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.

Hello sammy339 ,
You can try using field parameter to achive the above logic..
1. Add all the date columns (Column1, Column2, Column3) into the parameter >> Name the parameter something like DateSelector
DateSelector = {
("Column1", NAMEOF('Table'[Column1]), 0),
("Column2", NAMEOF('Table'[Column2]), 1),
("Column3", NAMEOF('Table'[Column3]), 2)}
2. Duplicate the DateSelector table and rename it as DateSelector2
3. Create Two Slicers with DateSelector(Dropdown1) and DateSelector2(Dropdown2)
4. You now need a measure to calculate the difference between the two selected dates
Date Difference =
VAR SelectedDate1 = SELECTEDVALUE(DateSelector[DateSelector Value])
VAR SelectedDate2 = SELECTEDVALUE(DateSelector2[DateSelector Value])
RETURN
IF(
ISBLANK(SelectedDate1) || ISBLANK(SelectedDate2),
BLANK(),
DATEDIFF(SELECTEDVALUE('Table'[SelectedDate2]), SELECTEDVALUE('Table'[SelectedDate1]), DAY))
5. Add the project names and this Date Difference measure to a table visual.

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.
