Time difference between date time values in same column based on a value in a different column

Hi Anonymous ,

Here is the pbix PBIX 
I put both columns in so that you have your choice, the second column only shows in the last row of the user. The difference between the measure and the column at the high level, is that with a measure, the engine does not have row context, whereas in the table it does. (It knows which row it is operating on.) Therefore it was just a matter of dropping MAX().

Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.
