    Pending the response to my questions above, try this:

    Cnt of units V2 :=
CALCULATE (
    SUMX ( VALUES ( 'Units'[unit_id] ), 1 ),
    VAR minDate_ =MIN ( 'CalendarTable'[Date] )
    VAR maxDate_ = MAX ( 'CalendarTable'[Date] )
    RETURN
        FILTER (
            ALL ( 'Units'[unit_valid_from], 'Units'[unit_valid_to] ),
            NOT ( maxDate_ < 'Units'[unit_valid_from]
                || minDate_ > 'Units'[unit_valid_to] )
        )
)

AlBThank you, your first code works like a charm 😎

Result after your DAX code:

 

In second code I don't get the right results. I didn't had time yet to go in deep why..

 

Best regards, v

    The second should do the same as the first. If the results are not right, it probably has to do with the relationships on the model. I made some assumptions, like no relationship between the date table and the Units table, that seemingly do not hold.
