Bill Of Materials BOM

To produce a product with different variants, you can create super Bill of Materials 
that has a list of components to manufacture different variants of a product

Own notes

One Material is made up different components at different levels which are materials them selves.

Like, A material called APPLE is has BOM which has components like seeds, skin, pulp which are also materials.

There can be different levels of BOM.

        Main Material

       /       |       \

      /        |        \

 L1M1   L1M2   L1M3

                        /    |  

                              /        |
                         L2M1   L2M2
