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.
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?
