How to assign last value of a month to the first value of the next month

[Anonymous]

This is my table, I want the closing stock value of a client for a particular month to be assigned to the opening stock of the next month.

example : 12/31/2020 value is 18079, I want this to appear on 1/4/2021, but what i have is 34984.

Is there a way to do this, pls help its urgent

@Anonymous , With help from the date table, try openingbalancemonth

openingbalancemonth(Sum('Table'[Value]), Date[Date])
