    Hi  Anonymous ,

    Here are the steps you can follow：

    1. Increase the index through power query

    2. Create calculcated column.

    Delta-values =
var _lastindex=
CALCULATE(MAX('Table'[Index]),FILTER(ALL('Table'),[Metern]=EARLIER([Metern])&&[Index]<EARLIER([Index])))

var _lastdata=
CALCULATE(SUM('Table'[Data]),FILTER('Table',[Index]=_lastindex))

return IF(_lastindex=BLANK(),BLANK(),[Data]-_lastdata)

    3. Result.

    You can downloaded PBIX file from here.

     

    Best Regards,

Anonymous , Try formula

 

Column = var _1 = MAXX(FILTER('Table',[ID] =EARLIER('Table'[ID]) && [Date] <EARLIER('Table'[Date])), LASTNONBLANKVALUE('Table'[Date],'Table'[Values]))
return if( ISBLANK(_1), BLANK(),[Values]-_1)
