Calculate Difference between 2 rows based on another column filter

  I would want to find the difference in the GenHours for each serialid. Currently this is how my table looks on power BI. I have filtered the latest and 2nd latest date for each serialid.   ...

    Hi,

    This calculated column formula works

    =if(CALCULATE(MAX(Data[Dates]),FILTER(Data,Data[serialid]=EARLIER(Data[serialid])))=Data[Dates],ABS(Data[GenHours]-LOOKUPVALUE(Data[GenHours],Data[Dates],CALCULATE(max(Data[Dates]),FILTER(Data,Data[serialid]=EARLIER(Data[serialid])&&Data[Dates]<EARLIER(Data[Dates]))),Data[serialid],Data[serialid])),BLANK())

    Hope this helps.

Hi,

Write these measures

D = CALCULATE(MIN(Data[timestamp]),Data[descript]="Dispatched")
A = CALCULATE(MIN(Data[timestamp]),Data[descript]="Arrived")
Response time = [A]-[D]

Hope this helps.

    Thank you so much...  This works well when used in a Matrix that groups by incident id and unit.  I modified it slightly to get the format I needed:

    Response time = If([A]=0," ", FORMAT([A]-[D],"h:mm:ss"))
    Is there a way to get the Maximum time to show in the incident id part of the matrix instead of the minimum?

    You are welcome.  I do not understand your requirement.  Please show the expected result very clearly.

    I am looking to get the maximum unit response time to appear on the line for the incident ID.  Currently, I am getting the minimum time for all incident ids.  For this case, instead of the 6:50 it should show 13:57.

    Hi,

    Try this measure

    Response time_new = MAXX(Values(Data[Inci_id]),[Response time])

    Hope this helps.

    That is still giving me the least or minimum time of all units for that Incident under the Incident ID row.  I am trying to get the maximum time.
