Steps to setup Direct Production in SAP

Hello gurus.

Could someone post a link to a guide; or the steps to setting up Direct Production in a Plant?

We have a final assembly that has a multilevel BOM; what we want is to create one production order for the final assembly and have the production orders of all subassemblies below it automatically created and linked to the final assembly.

We would like to be able to confirm the Production Order for the final assembly and have the rest of them automatically confirmed as well, performing all of the backflushes and costing necessary.

Thank you.
