Trailing Headcount Calculation

[Anonymous]

Hello All, 

I am trying to create a measure that will allow me to calculate a trailing 30, 90, and 365 day head count and attrition figures. My data is a list of employees by name, ID and their Status (active or Terminated). I also have a date table with a "DayOffset" field. This reads as "0" = today, -1 = yesterday, -30 = 30 days ago and so on...My formula that I am trying for the trailing 30 Headcount calculation is the following but not quite getting it done:

"

30 TD HC = COUNTAX(FILTER('Headcount - Trailing', [Status] ="Active" && FILTER('eis Date', [DayOffset]>=-30<=0) ),[Employee Number])"

I am getting the error about multiple columns not being able to be converted into a scalar value. Does anyone have any insight? Many thanks in advance!! 

Cheers

Hi @Anonymous 

Try

a =
CALCULATE (
    DISTINCTCOUNT ( 'Headcount - Trailing'[Employee Number] ),
    'Headcount - Trailing'[Status] = "Active",
    'eis Date'[DayOffset] >= -30,
    'eis Date'[DayOffset] <= 0
)

This assumes a proper 1-Many relationship between 'eis Date' and the fact table 

If it does not work dp share a sample of the tables involved
