Acumulated sum reset on 0, by item and plan

[guillelo]

Hello everybody, 

I´m get stuck trying to look for a solution for my question, but i havent find yet. 

I would lik to calculate in Power bi the stock evolution 

Table in excel looks like this

I have different materials, and different plans (weekly consuptions are different column E), so basically the formula in column H (line 2) is Initial stock (column F) + arrivals (D) - consumption (F)

line 3 would be Stock line 2 - 3752 + arrivals (D) - consumption (F) =840

line 4 would be Stock line 3 -  840+ arrivals (D) - consumption (F) =-2072 (0 stock)
line 5 would be Stock line 4 - 0 + arrvials (7000) - consumption =4500

I would like to know which formula fit better, taking into account that the accumulative stock have to be reset when previus week is 0, with the assumption of differnts item and differents plans, 

thanks

I have this formula

but it doesnt reset when previus value is <0

instead of 26394 (-21188+60000-12418) must be 60.000 - 12418 =47582

how to reset the accumulate value??thanks
