PowerBI - Cumulative Total with Multiple Criteria

votes

New to PowerBI, so forgive me for the description here. I'm working with a dataset of retail headcount sensors, which gives me a table of locations, timestamps, and a count of shoppers:

Room     TimeStamp     Count_In
123      3/13/2019     8
456      4/4/2019      9
123      3/28/2019     11
123      3/18/2019     11
456      3/22/2019     3
etc...

I'm trying to calculate a running total for each "room" over time. The overall running total column is easy:

C_In =
CALCULATE (
    SUM ( Sheet1[In] ),
    ALL ( Sheet1 ),
    Sheet1[Time] <= EARLIER ( Sheet1[Time] )
)

But I'm unable to figure out how to add that second filter, making sure that I'm only summing for each distinct location. Help is appreciated!

Your ALL function removes all context on Sheet1, try using ALLEXCEPT to keep the row context of the Room.

C_In =
CALCULATE (
    SUM ( Sheet1[In] ),
    ALLEXCEPT ( Sheet1, Sheet1[Room] ),
    Sheet1[Time] <= EARLIER ( Sheet1[Time] )
)
