A PBOM (Purpose BOM) is a BOM by which a user can update elements from an EBOM, FBOM, and MBOM. The PBOM enables the user to make suggestions for updates to the other BOMs, to clarify the purpose of the BOM so that a new final asset can be produced. See Understand Bill of Materials (BOM) Types for additional information.
PBOMs are created in Innovator and can only be created for an asset previously published from Unified Engineering.
