Date/Time Difference between ID

Dear Power BI Community

 

Following Task to solve:

Let's assume this table:

 

qwertzuiop_0-1685966651182.png

We are looking for the date/time difference of an ID from the first to the last Occurence

 

Any ideas how to solve this problem?

Thank you very much for your contribution.

 

Cheers

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:

@qwertzuiop Please share your ENDOUTPUT in table for more understanding.

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?)
