Identifying Changes Made to a Source SBOM Associated with a Parts List
There are two options for listing the changes that have been made to an SBOM:
• The Compare to part structure action in the BOM tab of a parts list’s structure
For more information, see Starting a Part to Part Structure Comparison.
• The Compare Information action in the Parts Lists Requiring Update report for a product’s information structure
For more information, see Parts Lists Requiring Update Report.
