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 axk180022,

 

Are you able to provide the data as a table as opposed to an image and the expected outcome. Not sure I understand the requirement based on your post.

 

Thanks,

    The one highlighted is the output I require, Which is the difference of GenHours between 2 latest dates.
