E1:34: BOM & Substitute Bill in BOM

Hello

Could anyone share the KB article on enterprise one JDE 9.2-

I) how to manually create a bill for a parent item?

II) And let's say some bills could be substituted by alternate raw material then in which table we can add this substitute item and respective quantity ?

III) And lastly once a work order is created how to choose the alternate material in case of availability issue in the main bill

If the KB article exists which could explain step by step this process, I can test it out by following these steps

Thank you
