The demand for subassembly $S$ is $140$ units in week $7.$ Each unit of $S$ requires $2$ units of $T$ and $2$ units of $U.$ Each unit of T requires $2$ units of $V,2$ units of $W,$ and $1$ unit of $x.$ Finally, each unit of $U$ requires $1$ unit of $Y$ and $3$ units of $Z.$ One firm manufactures all items. It takes $2$ weeks to make $S,1$ week to make $T,2$ weeks to make $U,2$ weeks to make $V,3$ weeks to make $W,1$ week to "make $x,2$ weeks to make $Y,$ and $1$ week to make $Z.$

Suppose that in addition to $140$ units of $S,$ there is also a demand for $20$ units of $U,$ which is a component of $S.$ The $20$ 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.

Construct a new net material requirements plan $($enter your responses as whole numbers$).$
