    Hi qwertzuiop ,

     

    Please try:

    TimeDiff_from_FirstTime_to_LastTime = 
var _a = MAXX(FILTER(ALL('Table'),[ID]=SELECTEDVALUE('Table'[ID])&&[CheckOccurence]="FirstTime"),[Date/time])
var _b = MAXX(FILTER(ALL('Table'),[ID]=SELECTEDVALUE('Table'[ID])&&[CheckOccurence]="LastTime"),[Date/time])
return DATEDIFF(_a,_b,MINUTE)/(60*24)

    Final output:

    Best Regards,

      Hi Mahesh0016 

      Hopefully with this visualisation I can better represent my desired output.

      It is not necessarily important that the output is in the corresponding line. What is important is that somewhere there is information that, for example, ID MDY5MP takes approx. 3,999 days from first to lasttime (maybe best approach in a measure, no?)

       


      Let me know if you need further information.

      Thank you
