Mean Time To Repair

[Anonymous]

Hi Guys

I want to work out the Mean Time To Repair for our Helpdesk

I have the TicketLoggedDate and the TicketClosedDate (both values with date/time)

I have managed to use DATEDIFF to get the time difference which is fine, but I am struggeling to add a formula that will only take in consideration working hours from 8AM to 5PM

MeanTimeToRepair = DATEDIFF(JOB_TICKET[TicketLoggedDate],JOB_TICKET[LAST_UPDATED],DAY)

If someone can help me with a formula that would be AMAZING!

Thank you in advance

Hi MorneLandsberg,

According to your description, my understanding is that you want to calculate the net working hours. PowerBI doesn't provide a function to do it directly, as a workaround, we can write the expression manually, please refer to this case: https://community.powerbi.com/t5/Desktop/Calculating-Working-hours/td-p/374255

Best Regards,

Thank you @TeigeGao 

I am trying that formula and coding but as others on that page I am also getting the "The start date in Calendar function can not be later than the end date"

I have checked that my TicketLoggedDate and TicketClosedDate is set to "Date/Time" and the correct Format as well
