BOM Structures
The following table displays the reporting relations for BOMs. When a product or
project is
structured
, all its components and subassemblies fit into a tree of
reporting or parent relationships. Products at Bay Networks follow certain rules
that determine how these components are contained within others.
The numbers shown in Table E-4, Table E-5, and Table E-6 are the class codes for
the various parts of the reporting structure that have been defined.
