BOM Management - General Concept
There is not only one view to a product;
Different disciplines will look differently to products and their describing information
A summary of these views are :
As-Specified
As-Designed
As-to-be-Manufactured
As-Planned
As-Manufactured
As not all views are used by the same disciplines, not all views are therefore created,
maintained and used within the same systems.

BOM Management - Business Requirements
The As-Designed (eBOM) and As-to-be-Manufactured (mBOM) views do not necessarily have to be the same.
Main reasons for eBOM / mBOM differences are:
Removal of (sub) assemblies that do not exist in the physical world.
Addition of non-design items which are needed for manufacturing the product
Therefore :
Manufacturing Engineers must be able edit the mBOM for restructuring purposes (Manufacturing Kits).
Manufacturing Engineers must be able edit the mBOM to add unique manufacturing content (nondesign items, Consumables) etc'.
mBOM updates should not modify the eBOM structure.
Manufacturing Engineers should control the mBOM update process.
Changes must be accorded, recorded and maintained

Chosen Solution for Customer X
According to the Best Practices from the field…
eBOM and mBOM shall be separate item structures
Manufacturing Engineers shall have read privileges
on the eBOM and write privileges on the mBOM
Modifications to the eBOM and mBOM structures
shall be done using Change Procedures
