Hi
Change the costing date periods
From period - u say start of the period
It will create cost estimate from the beginning of Aug.  Mark it, when u do so it updates the future std cost in costing 2 view
Then in Nov u can release the cost
U cannot open seot until aug is closed and all MM transactions are completed. 
Hope the above clarifies - pls assign points
