A Measure to Calculate the Cumulative Sum of Another Measure, with Filter on Measure

[ylin88_waters]

Hi

What’s the DAX code to create a measure that calculates the cumulative sum of another measure?

My data is something like following:

Customer	Sales	Rank (measure)	% of Total (measure)	Cumulative % (new measure)
A	1000	1	33.3%	33.3%
B	800	2	26.7%	60.0%
C	500	3	16.7%	76.7%
D	400	4	13.3%	90.0%
E	300	5	10.0%	100.0%

Both “Rank” and “% of Total” are measures. Now I need to create another measure “Cumulative %” to sum up on the measure “% of total”.

Many examples I found are for the calculation of cumulative sum on columns, not measures, or the filter is on the column values. but here it seems I need to filter on a measure (Rank). How do you get that Rank # into your DAX code and then sum up on “% of Total”?

Thanks!

Hi @ylin88_waters ,

Check the formula.

Measure = SUMX(FILTER(ALLSELECTED('Table'),[_rank]<=MAXX('Table',[_rank])),'Table'[_% of Total])

Hi @ylin88_waters 

Try this:

Cumulative % = 
Var _R = [Rank]
Var _A = SUMMARIZE(all('Table'),'Table'[Customer],'Table'[Sales],"Rank",[Rank])
Var _B = filter(_A,[Rank]<=_R)
Var _C = SUMX(_B,[Sales])
return
_C/CALCULATE(sum('Table'[Sales]),all('Table'))

output:

@ylin88_waters try something like this:

**bleep** Sum = 
VAR __rank = [Rank Measure]
RETURN SUMX ( FILTER( ALL ( 'Table' ), [Rank Measure] <= __rank ), [% Total] )

Hi VahidDM & parry2k:

Thanks a lot for your help.

I tried both of your sample codes, but they didn't work. It seems the Dax didn't really capture the Rank (a measure) of current row.  It actually calculated the sum of all rows. It seems I can't upload my testing file here(using 1000 rows of dummy data), so I just put an image of the result table.

Measures:

Sales $ = SUM('Sales_test'[Sales])

====================

Rank =

RANKX( ALLSELECTED(Sales_test[CustomerID]),'Sales_test'[Sales $])

=================

% of Total Orders =

DIVIDE( [Sales $],

CALCULATE( [Sales $],

ALL('Sales_test'[CustomerID])

))

===================

Cumulative % 1 =

VAR myrank = [Rank]

RETURN SUMX ( FILTER( ALL ( 'Sales_test' ), [Rank] <= myrank ), [% of Total Orders] )

 ====================

Cumulative Sales 1 =

VAR __rank = [Rank]

RETURN SUMX ( FILTER( ALL ( 'Sales_test' ), [Rank] <= __rank ), [Sales $] )

==============

Cumulative % 2 =

Var _R = [Rank]

Var _A = SUMMARIZE(all('Sales_test'),'Sales_test'[CustomerID],[Sales],"Rank",[Rank])

Var _B = filter(_A,[Rank]<=_R)

Var _C = SUMX(_B,[Sales $])

return

_C/CALCULATE(sum([Sales]),all('Sales_test'))

 =====================

If you see anything I need to change to make it work, le tme know. Thanks again.
