-- following needs to be integrated into above

--  rules
--  provisions for requests to change bom or order through an approval workflow --before the change is accepted (ECO)
--  bom must be designed to handle the most demanding functions: planning
--  superbom includes labor/routing with bom, and requirements (think baking recipe etc)
--  multiple views of bom
--  bom references are unique
--  bom includes quantity (manufacturing might result in creation of more than 1 created per bom, for example 1 pipe cut in half creates 2 pipes...)
--  have provisions for handling perishible goods
--  bom refeerences are different than drawing references
--  bom includes all materials to be scheduled
--  bom editing UI is designed to minimize depth of dependencies
--  template boms (used during design process) --optionally use specification parameters (called modularizing) to minimize the number of templates. (a kind of parts number system by specs) --also a revision number
--  orders copy template to their own spec set. (handy for lot number controls, customization, substitutions etc), can create a serial number for each part.
--  addition of a table to handle customized fields (in the same manner as ecommerce package does)
--  
--  When to assign part numbers: every item represented in the system has at least an internal part number. Formal numbers are optional if not specified.
--  parts_master table (links to data in other tables)
--  part_number
--  other_table_name other_table_reference (make these external keys?)
--  (maybe this is an object folder with the CR)? No (or yes, but scary because) CR uses ad_conn for some code with causes problems with scheduled procs. Scheduled procs will be heavily relied on for forecasting and planning, as well as mainenance. CR is meant for more generalized uses, this is a specific datamodel with specific requirements.
