Previous Month Headcount

Hi all, 

 

I am trying to calculate previous months headcount. I have the below to calculate the headcount per month 

Headcount =
var selectedDate = MAX('Date'[Date])
RETURN
CALCULATE(DISTINCTCOUNT('Headcount by Function'[EMP_NO]),
'Headcount by Function'[VALID_FROM] <= selectedDate, OR(ISBLANK('Headcount by Function'[VALID_TO]),
'Headcount by Function'[VALID_TO] > selectedDate))
 
I am looking for previous months headcount from the month year chosen from the slicer. If i select Oct2020, i will need to dsiplay Sept2020 headcount 
 
Thanks

Hi, @yaman123 

 

According to your description, if you have month and year column in date table, you can try like this:

Headcount =
VAR year =
    SELECTEDVALUE ( 'Date'[year] )
VAR month =
    SELECTEDVALUE ( 'Date'[month] )
VAR date =
    DATE ( year, month, 1 )
VAR previousfirstday =
    EDATE ( date, -1 )
VAR previouslastday =
    EOMONTH ( date, -1 )
RETURN
    CALCULATE (
        DISTINCTCOUNT ( 'Headcount by Function'[EMP_NO] ),
        'Headcount by Function'[VALID_FROM] >= previousfirstday
            || ISBLANK ( 'Headcount by Function'[VALID_TO] ),
        'Headcount by Function'[VALID_TO] <= previouslastday
    )

If it doesn’t solve your problem, please feel free to ask me.

Can you try the following formula.

 

Previous Month Count = CALCULATE(DISTINCTCOUNT('Headcount by Function'[EMP_NO]),DATESMTD(DATEADD('Date'[Date],-1,MONTH)))

OR

Previous Month Count = CALCULATE(DISTINCTCOUNT('Headcount by Function'[EMP_NO]) PREVIOUSMONTH('Date'[Date]))

 

 

 

Hi @themistoklis 

 

This doesnt work unfortunately. It brings back all employees even those who have left. I only need to show employees who were with the business last month 

@yaman123 

Do you want selecteddate to be the last date (31/01/2021) of previous month? 

If this is the case then try the following formula:

Headcount =
var selectedDate = EOMONTH(TODAY(),-1)
RETURN
CALCULATE(DISTINCTCOUNT('Headcount by Function'[EMP_NO]),
'Headcount by Function'[VALID_FROM] <= selectedDate, OR(ISBLANK('Headcount by Function'[VALID_TO]),
'Headcount by Function'[VALID_TO] > selectedDate))
