COUNTIFS equivalent to count the number of times two values appear in my data set

[davidoz]

I have a data set of units of equipment. The user enters a start date, an end date, and the Unit Reserved for that job. Powerquery then expands the data to populate a new row for every day that unit will be used:

eg.

5/24/2022 SC-0037

5/25/2022 SC-0038

5/26/2022 SC-0039 etc... Please refer to screenshot below

Because the data entry is manual, I need to know if a particular unit is double booked on a certain date. In excel I would do this:

=COUNTIFS ( C:C , C2 , G:G , G2 ) 

I've searched for over an hour and I can't figure out how to do the same thing in PowerBI. Please help

Hi @davidoz ,

I'm guessing you want a calculated column. You can build something like this:

CountDuplicates = 
VAR _Check = CALCULATE(COUNTROWS(YOUR_TABLE), FILTER(YOUR_TABLE, YOUR_TABLE[Date] = EARLIER(YOUR_TABLE[Date]) && YOUR_TABLE[UnitReserved] = EARLIER(YOUR_TABLE[UnitReserved])))
RETURN
IF(_Check > 1, 1, 0)

Let me know if that works.
