Delta values
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.

Hi Anonymous ,
Here are the steps you can follow：
1. Create calculcated column.
Delta-values =
var _max=MAX('Table'[Date])
var _min=MIN('Table'[Date])
var _1=
CALCULATE(SUM('Table'[Values]),FILTER('Table','Table'[Date]=_max&&'Table'[ID]=EARLIER('Table'[ID])))
-
CALCULATE(SUM('Table'[Values]),FILTER('Table','Table'[Date]=_min&&'Table'[ID]=EARLIER('Table'[ID])))
return IF('Table'[Date]=_min,BLANK(),_1)
2. Result.

Thanks Liu,
I followed your steps, and also ended up with a column - however the values seems wrong and does not reflect the expected delta-value as in your example,
Where did I go wrong?
