Function to be used...?

[KatkaS]

Hello,

I would need to calculate difference between Time Stamps of the same Assignements numbers (always two rows)...

Could you please advice how to use Power BI in this?

Thank you very  much!

Hi @KatkaS , in the _diff, you can change the unit. I used hour.
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.

Time lapse = var _curTime = 'Time'[Time stamp]
var _calc = CALCULATE(MAX('Time'[Time stamp]),ALLEXCEPT('Time','Time'[Assignment]),'Time'[Time stamp]<_curTime)
var _diff = DATEDIFF(_calc,_curTime,HOUR)
return _diff
