create cumulative column undated and index measure

[alexsandro]

I need to create an accumulated column but, without using date. I created an index column via measure without using the power query because I need this accumulated to move if I change department or period. I tried to use this index, I tried to create a counter to maybe add to the previous value, but the Earlier function just doesn't work, nor does it recognize dimension columns.

my data is currently as follows.
I'm just using only one column the rest of the other columns are measured.

"I created an index column via measure "

How? And based on what? 

[alexsandro]

don't have column indice, I deleted. 
it is possible only with the data in the attachment?

I mean, you can do a RANKX based measure, but without any context I am hesitant to recommend any particular approach. Please provide a more detailed explanation of what you are aiming to achieve. What have you tried and where are you stuck?

I need to create an accumulated that is flexible according to the value of sales (measures).

I tried to create a dynamic index, but I couldn't

so I can create a dynamic abc curve.

Here is your dynamic cumulation

cumul = 
var s = sum(abc1[sumSalesRevenues])
var p = max(abc1[COD_PRODUCT])
var a = CALCULATETABLE(values(abc1[COD_PRODUCT]),REMOVEFILTERS(abc1[COD_PRODUCT]))
var b = ADDCOLUMNS(a,"sm",var p = [COD_PRODUCT] return calculate(sum(abc1[sumSalesRevenues]),abc1[COD_PRODUCT]=p))
var c = FILTER(b,[sm]>=s)
return  divide(sumx(c,[sm]),sumx(b,[sm]),0)

see attached pbix

Thanks  Ibendlin, it's perfect!

based on values of sales.
