Slicer issue

Hi Tezaroyal ,

Please try:

TotalNights = 
VAR startdate =
    MIN ( 'Calendar'[Date] )
VAR enddate =
    MAX ( 'Calendar'[Date] )
VAR ArrivalDate =
    SELECTEDVALUE ( 'report vwRevenueDashboardReport_Data'[ArrivalDate] )
VAR DepartureDate =
    SELECTEDVALUE ( 'report vwRevenueDashboardReport_Data'[DepartureDate] )
VAR AdjustedArrivalDate =
    IF ( ArrivalDate < startdate, startdate, ArrivalDate )
VAR AdjustedDepartureDate =
    IF ( DepartureDate > enddate, enddate, DepartureDate )
VAR Result =
    SWITCH (
        TRUE (),
        AdjustedArrivalDate <= AdjustedDepartureDate
            && DepartureDate > enddate, DATEDIFF ( AdjustedArrivalDate, AdjustedDepartureDate, DAY ) + 1,
        AdjustedArrivalDate <= AdjustedDepartureDate, DATEDIFF ( AdjustedArrivalDate, AdjustedDepartureDate, DAY ),
        0
    )
RETURN
    Result
