DAX Query - COUNTROWS statement using EARLIER - powerpivot

Question

I need to compare :
Contact Employee ID to EARLIER Contact Employee ID (if they equal)
and difference between Opendate_Int and EARLIER Opendate_Int (if less than or equal to six then count the row).
My query (Data is the name of the table in Power Pivot):
=COUNTROWS(FILTER('Data', EARLIER([Contact Employee ID]) = [Contact Employee ID] && EARLIER(Data[OpenDate_Int],[OpenDate_Int]-[OpenDate_Int]) <=6))+1
I am getting an error:
"The second argument of function EARLIER must be an integer greater than zero."
Can you tell me where I am going wrong? Example (tables):

Answer 1

Your error is thrown due to this part of your measure:
EARLIER(Data[OpenDate_Int],[OpenDate_Int]-[OpenDate_Int])
The EARLIER function in dax takes two arguments. The first argument is mandatory and should be a column. The second argument is optional and should (if provided) be an integer greater than 0.
In your statement the second argument is this:
[OpenDate_Int]-[OpenDate_Int]
which will always resolve to 0, because you are basically substracting a number from itself.
I assume that what you want to achieve is this:
=
COUNTROWS(
FILTER(
'Data',
EARLIER([Contact Employee ID]) = [Contact Employee ID]
&& EARLIER([OpenDate_Int])-[OpenDate_Int]) <=6
)
)+1
This part of the statement:
&& EARLIER([OpenDate_Int])-[OpenDate_Int]) <=6
will check whether the [OpenDate_Int] subtracted from the EARLIER [OpenDate_Int] is less than or equal to 6.
