Here is a measure expression that seems to work. Replace T4 with your actual table name.

Remaining =
VAR maxdate =
    MAX ( T4[MONTH] )
VAR result =
        SUMX ( t4, T4[STOCK] - T4[DEMAND] ),
        T4[MONTH] <= maxdate
    IF ( result > 0, result, 0 )

this works great , i thought i could figured out with that simple example , but i cant addapt it to mi example , i attach a pbix to show mi particular case , because the data its stored in different tables like 

stock : its the initial stock snapshot at the beginning of the month by country and product

demand :its the yearly demand by country , product and month

country: its the dim country

product :its the dim product

transit : its the future income of products , it should be add to the stock on a specific date 

calendar table : calendar dim
