DAX Running Totals

[NGC48]

I'm not sure if I have missed this somewhere but is it possible to create a DAX running total ignoring 'Weekends'? Using the Northwind Odata as an example, could an RT be calculated against the Freight column that counts 60 working days (Mon - Fri). Starting 04/07/2016, 60 Working days would end 25/09/1996. 

Thanks for any help on this.

Hi @NGC48 

I created a calculated column in my date table.

WorkDay Offset = 
VAR _d = NETWORKDAYS( TODAY(), 'Date'[Date], 1 ) - 1
RETURN
    IF( _d < 0, _d + 2, _d )

After creating a 1:* relationship between 'Date'[Date] and 'Sales'[Date], I created these measures.

Freight = SUM( 'Sales'[Freight] )

60 weekdays = 
VAR _Offset = SELECTEDVALUE( 'Date'[WorkDay Offset] )
VAR _Result =
    CALCULATE(
        MAX( 'Date'[Date] ),
        FILTER(
            ALL( 'Date' ),
            'Date'[WorkDay Offset] = _Offset + 60
        )
    )
RETURN
    _Result

Freight 60 = 
VAR _Start = SELECTEDVALUE( 'Date'[Date] )
VAR _End = [60 weekdays]
VAR _Result =
    CALCULATE(
        SUM( 'Sales'[Freight] ),
        DATESBETWEEN(
            'Date'[Date],
            _Start,
            _End
        )
    )
RETURN
    _Result

Let me know if this helps.

Thansk @gmsamborn. Trying to create a cumualative RT.  Your sample data includes Freight cost for 'weekends'. In my data (Sat,Sun) would not have any values as they are non-operational days. But has given me food for thought.

Regards.
