Hello, PowerBi newbie here: I have the following two tables below and I am trying to make a measure that calculates: Number of Business Days – Returns the count of IsBusinessDays in a filtered repo...

    Try this example 

    NumberOfBusDays =
VAR _maxdate =
    MAX ( 'Date Table'[Date] )
VAR _mindate =
    MIN ( 'Date Table'[Date] )
VAR _hiredate =
    CALCULATE ( SELECTEDVALUE ( 'Member Table'[Hire Date] ) )
VAR _r =
    CALCULATE (
        COUNT ( 'Date Table'[Date] ),
        'Date Table'[Date] > _hiredate
            && 'Date Table'[Date] < _maxdate,
        'Date Table'[IsBusinessDay] = 1
    ) 
// if the hire date is not in the date range, return blank.    
VAR _result =
    IF ( _hiredate < _mindate || _hiredate > _maxdate, BLANK (), _r )
RETURN
    _result

    Thanks! Its close, but I have one issue. Returning BLANK() for the result will not work. It needs to return a sum of the number of business days in that time period. I tried adding SUM('Date Table'[IsBusinessDay]), but it is not totaling correctly and affects the downstream calculations that us that NumberOfBusinessDays measure. For example, Hourly Capacity is 8*NumberofBusinessDays:

     

    NameNumberOfBusinessDaysHourly Capacity
    Member 1540
    Member 2540
    Member 3324
    TOTAL540

Here's the code. It returns the number of business days in any period of time for any one member. If many members are visible in the current context, BLANK is returned since you have not given a definition for the number when this condition is in force.

 

 

// Member - dimension with Name (exposed), HireDate (hidden)
// Date - a calendar table in the model marked as such
//		  [Is Business Day] can be exposed
// Date is NOT connected to Member

[# Member Business Days] =
var __hireDate = 
	SELECTEDVALUE(
		Member[HireDate],
		DATE(3000, 1, 1) 
	)
var __result =
	COUNTROWS(
		'Date',
		KEEPFILTERS( 'Date'[Is Business Day] = 1 ),
		KEEPFILTERS( 'Date'[Date] >= __hireDate )
	)
RETURN
	__result
