Counting Unique Activities Based on Customer Number and Date Time

Hi all,

 

I need to de-duplicate some data refering to meetings in a Dax Measure. A duplicate meeting is a meeting where the same customer has a meeting at the same date time, this would be one meeting. I need to count unique meetings. As in the below data there would be 7 Unique Meetings.

I hope that's clear, happy to answer any questions.

 

Thanks,

 

Adam

The following measure will count unique meetings
UniqueMeetingsCount = COUNTROWS(
    SUMMARIZE(
        'Table',
        'Table'[Customer Number],
        'Table'[Date Time]
    )
)

Instead of taking complete table in summarize you can use this filter.

FILTER(Meetings, Meetings[Meeting Status] = "Attended")

Please accept the solution if the measure works.

Thank you : )

Thanks @nirali_arora that's a quick response.

 

That measure worked.

 

How would I add a additional filter to include an additional field -  [Meeting status] that are "Attended"? Would I wrap it all in a CALULATE function?

 

Thanks,

 

Adam
