 Hello,

Last time i was asking how to display new employees of the current month compared to the previous month in a datasheet

in January we had John, Carter, Kim and Alexander.

In February we have John, Carter, Kim, Alexander and Sienna.

The visual should then show me only Sienna

This is the solution that worked for me : 

Flag = 
var _preMonth=DATEADD('Table'[Month],-1,MONTH)
var _preEmps= SUMMARIZE(FILTER(ALL('Table'),YEAR([Month])= YEAR(_preMonth) && MONTH([Month])=MONTH(_preMonth)) ,[Name of Employees])
return IF(_preMonth<>BLANK(),IF( MAX('Table'[Name of Employees]) in _preEmps,0,1))

Now i would like to have the list of all the employees who have disappeared (they are no longer in the database) 

Example : 

The visual should then show me only : Carter and Alexander

Can you please help ?

Best regards,

Rena.

Hi @Anonymous ,

You can just change your expression like so:

Flag 2 = 
VAR _curMonth =
    DATEADD ( 'Table2'[Month], 1, MONTH )
VAR _curEmps =
    SUMMARIZE (
        FILTER (
            ALL ( 'Table2' ),
            YEAR ( [Month] ) = YEAR ( _curMonth )
                && MONTH ( [Month] ) = MONTH ( _curMonth )
        ),
        [Name of Employees]
    )
RETURN
    IF (
        _curMonth <> BLANK (),
        IF ( MAX ( 'Table2'[Name of Employees] ) IN _curEmps, 0, 1 )
    )

Best Regards,

@Anonymous , Create a date using month year. Using common date and employee table follow this customer retention logic

Hi @Anonymous 
I hope "Month" is a date column. Then you can drag this measure into the filter pane and select "Not is blank"

Flag =
VAR NumberOfMonths = 1
VFlag =
VAR NumberOfMonths = 1
VAR CrrentPeriod =
    MAX ( 'Table'[Month] )
VAR PreviousPeriod =
    DATEADD ( CrrentPeriod, - NumberOfMonths, MONTH )
VAR LastPeriodEmployees =
    CALCULATETABLE (
        VALUES ( 'Table'[Name of Employees] ),
        'Table'[Month] = PreviousPeriod
    )
VAR CurrentPeriodEmployees =
    CALCULATETABLE (
        VALUES ( 'Table'[Name of Employees] ),
        'Table'[Month] = CrrentPeriod
    )
RETURN
    COUNTROWS ( EXCEPT ( LastPeriodEmployees, CurrentPeriodEmployees ) )
