In engineering there is a high demand to maintain product structures from the earliest stages of the development process up to the creation of a product prototype. Such product structures can contain detailed specifications, CAD data, product variants, and materials, all of which may need to be modified and tracked during the transition from an engineering bill of material (EBOM) to a manufacturing BOM (MBOM).

Here, we to use redlining to simplify the changing and displaying of material bills of material (MatBOM), as well as to track proposed and accepted changes to BOM items.

We want the users to propose changes to a BOM by redlining (deleting or adding items, changing quantities or other attributes). To facilitate collaboration, external users such as suppliers, partners, and manufacturing experts can also be authorized to create BOM redlinings.
