I have  column with Date / Time where the ticket is opend, the second columune include the Date / Time SLA.

HI p_fehrenbach 

 

Please consider using this solution in the M query .....

 

Define both the sla duration and actual duration with date time data types.

 

Add a column with Difference = sla duration - actual duration

Transform the Difference data type to minutes

Filter where the Difference  < 0

Many thanks for the answer. I had already tried that. unfortunately power query changes the type when I load the data into the model, from time to decimal. If I put the data back in time in the model, all decimal numbers are positive.

 

(The negativ value in this scenario is good one)

 

For Example in the last Row:

 

 

 

We finished te ticket at the 22.10.2019 16:30:00

It could have been closed until 23.10.2019 12:40.

The Result is + 20:10:00 hours.

The Result have to be - 20:10:00 hours.
