Filter column values based on 2 other columns
Hey folks,
I'm trying to create a column like the one to the right in the picture, where every line is a project and I need to add up everyone's work days YTD. If say, two projects have the same month and same person then only one would need to count to the YTD workdays. Any idea how to do this?
Thanks,
Pierre
Hello Pierre,
There could be better method but this DAX also works if you have a unique field the data set:
Distinct WD =
IF (
CALCULATE (
COUNTROWS ( Table1 ),
ALLEXCEPT ( Table1, Table1[Name], Table1[Date] ),
EARLIER ( Table1[Id] ) >= Table1[Id]
)
= 1,
[This Month],
0
)Thanks,
PrakashHello Pierre,
The AllEXCEPT gives the all rows of the table (for each Name and Date pair) and earlier gives the current row.
When we count all Id where Name and Date is equal AND current Id is >= all Id, we are left with the correct count.The >= might be confusing. Please see below MSDN link where earlier has been described in detail:

Hey Prakash could you explain to me how the Earlier function works in this scenario?
