Remove duplicates based on values from multiple cells

‎07-31-2017 05:27 AM

Hi Community,

 

We have dataset based on logs - here we would like to create a new column with a true/false value if the line is a duplicate.

We have UserID, LogTimeDate, LogTime, and number of logged lines. 

The Dax query should check if there are more entries with the same date and number of logged lines, and if so, flag the line with a true/false marking.

 

How would we go about formulating such an query?

 

Inputs are much appreciated.

 

Good day.

 

/David

@Dbjerring,

 

You could modify the formula as shown below.

IsDuplicate =
IF (
    COUNTROWS (
        FILTER (
            Logs,
            Logs[LogCNumber] = EARLIER ( Logs[LogCNumber] )
                && Logs[LogTime.1] = EARLIER ( Logs[LogTime.1] )
                && Logs[LogID] < EARLIER ( Logs[LogID] )
        )
    )
        > 0,
    TRUE (),
    FALSE ()
)
