Subtract Time based off of a variable

Anonymous — Mon, 06 Jun 2022 18:46:14 GMT

I'm really new to Power BI and was asked to create a report that shows the average drop off time at our warehouse. What is the best way to calculate the time difference based off of a variable in another column?

Essentially I need to take every UDC listed and see the time taken between the Pickup and Dropoff.

Hi Anonymous

you can try create a measure

Avg Time = AVERAGEX ( VALUES ( TableName[UDC] ), CALCULATE ( DATEDIFF ( MIN ( TableName[TIME] ), MAX ( TableName[TIME] ), SECOND ) ) )

Thanks for the reply tamerj1

I input the code into Power BI and it gives me a Avg time of zero. I do have a filter set up so that it can limit the results down to the last 7, 14, and 30 days.

This is the code that I have put in.

Avg Drop Off Time =

AVERAGEX (

VALUES ( LOG_USER_AUDIT[UDC] ),

CALCULATE (

DATEDIFF ( MIN ( LOG_USER_AUDIT[TIME] ), MAX ( LOG_USER_AUDIT[TIME] ), SECOND )

)

I actually had to create a new table. Once I moved the function over there it started to work.

Avg Drop Off Time In Seconds = AVERAGEX ( VALUES ( 'IN THE LAST'[UDC] ), CALCULATE ( DATEDIFF ( MIN ( 'IN THE LAST'[Time Format] ), MAX ( 'IN THE LAST'[Time Format] ), SECOND ) ) )

Thanks for pointing me in the right direction.
