Use the following product structure tree to develop the MRP plan for the components A and $B.$ Finished product $x$ will be shipped $100$ quantities at the start of week $6$ and $90$ quantity at the start the week $7.$ One case of A $(50$ units in one case$)$ is scheduled at week $4,5,6,7$ and One case of $B(30$ units in one case$)$ is scheduled at week $5,6.$ There are $30$ units of A and $10$ units of $B$ now on hand. Lead time for all the components is one week.

Solution:

$\backslash \backslash$table$[[$Week$,1,2,3,4,5,6,7],[$Quantity$,,,,,,100,90]]$
