Was doing the Inventory ABC analysis, and need calculate the Culmmunative Share for the ABC , 

from the online vedios they using add a column then use the below fomula:

Culmmunative share %=Calculate(Sum(Inventory[revenue share%]),

                                                        Filtera(Inventory,Inventory[revenue share%]>=

                                                                    Earlier(Inventory[revenue share%])))

this one is not working for the DAX measure , only working for the culumn, but becasue the column is not working for the previous culumn when i want to calculate the revenue share as the revenue total is calculate by another table from online 365 dynamic service. So i couldnt use the column for the calcualtion.

Hope to find a way to use the DAX measure for this.

thank you if any experts have better solution for this
