Calculated Column for New Employee & Left Employee

[richardbadge]

Hi,

I have a table in Power BI that holds my Payroll information and it has a record per employee per month, as follows.

I would like to have a calculated column that works out the "New Employee" value and returns a 1 if the same employee number does not exist in the prior period, so in the example below, employee 90003 and 90004 return 1 for 01/02/2018 as these employee records did not exist for 01/01/2018.

I am pretty new to DAX so am struggling with how to do this, I have tried to search the web but can't seem to find anything that works for the below.

I 

Thanks in advance.

You can use this column

New Employee =
VAR temp =
    FILTER (
        Table1,
        Table1[Employee Number] = EARLIER ( Table1[Employee Number] )
            && Table1[Period] < EARLIER ( Table1[Period] )
    )
RETURN
    IF ( COUNTROWS ( temp ) > 0, 0, 1 )

Hi @Zubair_Muhammad ,

Really usefull solution!

This was something i always wanted to include to my reporting but i believe i need to adjust to solution according to my dataset.

My dataset has seperate calender table, in my case the 'period' column is in the seperate table. How can i create a relationship between the period column and employee start date column in another table?

You can see the .pbix file, really appreciate your help,

Thanks for that, it seems to work, but I do have 1 question. Does the EARLIER < ( Table1[period]) check if the employee existed in any period before? How would I change this to only look at the prior month record?

Also for browney points, what I have not asked for in the original post was the reverse logic to calculate an "Employee Left" flag which will be set to 1 if the employee does not exist in the following period, what DAX would do this?

Thanks again for your assistance

Thanks very much for your help, I have managed to tweak the formula as follows to get it to work to just look at the prior period, and have also created one for "Leavers" as follows

Starter = VAR temp = FILTER ( Payroll, Payroll[EmployeeNumber] = EARLIER ( Payroll[EmployeeNumber] ) && dateadd(Payroll[FinancialDate1stDay],+1,MONTH ) = EARLIER ( Payroll[FinancialDate1stDay]) ) RETURN IF ( COUNTROWS ( temp ) > 0, 0, 1 ) 

Leaver = VAR temp = FILTER ( Payroll, Payroll[EmployeeNumber] = EARLIER ( Payroll[EmployeeNumber] ) && dateadd(Payroll[FinancialDate1stDay],-1,MONTH ) = EARLIER ( Payroll[FinancialDate1stDay]  ) ) RETURN IF ( COUNTROWS ( temp ) > 0, 0, 1 ) 

I think the above seems to be working as expected.
