Suppose that in addition to $100$ units of $S,$ there is also a demand for $30$ units of $U,$ which is a component of $S.$ The $30$ units of $U$ are needed for maintenance purposes. These units are needed in week $6.$ Additionally, a new order has been received for $90$ units of $S$ due in week $8.$ Modify the net material requirements plan to reflect these changes.
