Measure Working Days between dates, dynamic but with no relationship with calendar

[sublog]

Struggling with this, need some help. I have 2 tables, a headcount file and a calendar table. My calendar table only goes back to 1-1-2017. 

I have created a Dax measure that correctly calculates the number of working days between the start date of their employement and the current date. However, I need this to be dynamic when I filter for month or year. Presently, the filter does not affect the calculation. 

Been working on this one measure literally all day...

Here's my measure = 

Working Days since Start Date = IF([Total Working Days] < CALCULATE(Sum('Calendar'[Workingdays]),DATESBETWEEN('Calendar'[Date],'Headcount File'[Effective Job Date],TODAY())),[Total Working Days],CALCULATE(Sum('Calendar'[Workingdays]),DATESBETWEEN('Calendar'[Date],'Headcount File'[Effective Job Date],TODAY())))

Total Working Days is a measure in my calendar table = 

Total Working Days = SUM('Calendar'[Workingdays])

The goal was for me to take the lesser of the Total Working days in a period (or) the total working days of employment.

Hi @sublog ,

You could try to get the value of slicer using the SELECTEDVALUE function firstly. Then use the value as a date range.

Table =
VAR a =
SELECTEDVALUE ( 'Calendar'[Date] )
RETURN
IF (
ISFILTERED ( 'Calendar'[Date] ),
IF (
[Total Working Days]
< CALCULATE (
SUM ( 'Calendar'[Workingdays] ),
DATESBETWEEN ( 'Calendar'[Date], a, TODAY () )
),
[Total Working Days],
CALCULATE (
SUM ( 'Calendar'[Workingdays] ),
DATESBETWEEN ( 'Calendar'[Date], a, TODAY () )
)
)
)

If you can upload a dummy file, we will help you as soon as possible. If you can't, can you please share some sample data?

Best Regards,
