Consuming Sub Boms to Final Boms

Hi currently i encountered a situation which is like the following scenario

Suppose my company Manufactures Computers. In one production order it manufactures 30 Monitors and in other 30 CPU’s and in other 30 CPU’s.

Now to make a single system i need to post these serial nos to Other Production Order whose final result is manufacturing a Computer.

How can i achieve this?

Create serial controlled BOM items and book them into stock through production and then use them in the production order for the final result consuming the previous items booked into stock.
