Cumulative sum of a measure

Hello All, 

 

I am struggling with getting cumulative totals of a measure I created under "GP per WR"

 

I basically want them to all add up to the previous periods going forward and the closest I got was with this formula which doesn't return correct results:

 

Cumulative GPH SK =
VAR SK = CALCULATE(FactPeoplePerPeriod[GP per WR],
FILTER(ALL(FactPeoplePerPeriod[periodNumber]), FactPeoplePerPeriod[periodNumber] <= MAX(FactPeoplePerPeriod[periodNumber])))
RETURN
IF(ISBLANK([GP per WR]), BLANK(),SK)

Any help would be appreciated

Ah, this does make things more clear.

 

[GP per WR] appears to be a ratio. Thus, the cumulative total is more like a cumulative average than a cumulative sum.

 

You can get the cumulative sum by iterating over the periodNumber along these lines

 

SUMX (
    FILTER (
        ALL ( FactPeoplePerPeriod[periodNumber] ),
        FactPeoplePerPeriod[periodNumber] <= MAX ( FactPeoplePerPeriod[periodNumber] )
    ),
    [GP per WR]
)

 

 but I'd take a minute to think about what this calculation actually means and how to interpret the numbers you get since summing ratios often doesn't make much sense (I don't know if it does in your case or not).
