Countrows and filtering

[drewmcspy]

Hi All

I have a dataset of former employees spread over 20 years with leaver reasons, I have a column created which flags whether the leave reason is voluntary or compulsory. I am trying to create a count which will count all voluntary leavers for the last 12 calendar months. The table is called 'Staff Data'.  Example data below.

LEAVE REASON	VOLUNTARY?	LEAVE DATE
Redundancy	no	20/12/2020
Career Change	yes	20/12/2018
Retirement	yes	15/05/2021
Dismissed	no	06/08/2021
Higher pay	yes	16/04/2020
Higher pay	yes	09/08/2021
Conflict with manager	yes	10/01/2021
Higher pay	yes	10/10/2020
Dismissed	no	12/11/2020

In the example data I'd like result to be 4 (Retirement in May-21, Higher pay in Aug-21 and Oct-20, Conflict with manager in Jan-21).

I have a 'Date' table created and in this table I have create a measure (LTM Dates) which should flag only the last 12 months, using 2 other measures (StartDate and EndDate).

StartDate = EDATE(EOMONTH(today(),-1),-12)+1
EndDate = EOMONTH(today(),-1)

Using the above I have this measure:

LTM Dates = IF(MAX('Date'[Date])>= [StartDate]&&MAX('Date'[Date])<=[EndDate],true(),false())

In order to count the rows I need including I know I need to filter and this is what I've got so far but it's not working. It would be great if you could point out where I'm going wrong please.

CountVol.LeaverLTM = COUNTROWS(CALCULATETABLE('Date',FILTER('Date','Date'[LTM Dates]=TRUE),FILTER('Staff Data','Staff Data'[Vol. Leaver]= "yes")))

Thanks

@drewmcspy , You are using date table, so you have active relation between date of Date table and leave date

measure =
var _min = EDATE(EOMONTH(today(),-1),-12)+1
vat _max = EOMONTH(today(),-1)
return COUNTROWS(CALCULATETABLE('Date',FILTER('Date','Date'[LTM Dates] <= _max && 'Date'[LTM Dates] >=_min),FILTER('Staff Data','Staff Data'[Vol. Leaver]= "yes")))

refer how to handle two dates

Thanks. I had an extra problem with TRUE/FALSE values but managed to sort it thanks to the extra link you shared.
