Count by Date Range - Looking for Help

[TapZxK]

Hi Everyone, 

I have encountered yet another problem that I'm looking to solve. 

I have a table with employee names that also contain their start-dates and roll-off dates.

Example:

Name // Start Date // Roll-Off Date 

Kris // 01-Sep-2018 // 12-Dec-2020

Alice // 01-Jun-2019 // 01-Oct-2019

Mark // 17-Jan-2018 // 10-Aug-2018

Karen // 03-May-2019 // 17-Oct-2018

Lisa // 27-Mar-2019 // 11-Sep-2020

What I'm looking for is a measure that will count the rows and return an "Active" Headcount, based on the data range.

For example, I want to know how many "Active" employees we have in October 2019. Measure then looks at the start date & end date of the employee and only returns Active head count number for people who's roll-off date is not in the past. For example using the table above, the total active headcount returned should be = 2, since only Kris and Lisa have Roll-off dates in the future. 

I then would like to create a slicer so I can go back to other month's and see how many Active people I had in May or June, or September and so on.

I'm fairly new to Power BI and I'm learning a lot. but this is something I can't yet figure out how to do. 

Your help is much appreciated. 

Best Regards,

Kris

Hi @TapZxK 

1. Create a standard calendar table (no relationships to the table you show). Place month and year in a slicer.

2.  Place this measure in a card visual (assumes only one row per employee in the table you show (Table1))

Measure =
VAR CutOffDate_ =
    MAX ( CalendarTable[Date] )
RETURN
    COUNTROWS ( FILTER ( Table1, Table1[Roll-Off Date] > CutOffDate_ ) )

Please mark the question solved when done and consider giving kudos if posts are helpful.

Hi @AlB ,

Thanks for the Suggestion. 

I already had a rolling-calendar created, There is no relationship between the Employe Table and calendar. 

What if the Roll-off date contains a lot of "Null" values as the people who are not yet rolled-off will not have the date in there. 

is it possible to amend the formula so that it also counts the null values too please?

BR,

Kris

Measure =
VAR CutOffDate_ =
    MAX ( CalendarTable[Date] )
RETURN
    COUNTROWS ( FILTER ( Table1, Table1[Roll-Off Date] > CutOffDate_  || ISBLANK( Table1[Roll-Off Date] ) ) )
