BOM vs Structure vs Occurrence (Clear Difference)

By Pankaj Verma••8 min read

A clear explanation of the difference between BOM, structure, and occurrence in Teamcenter thinking.

Simple definitions

  • BOM — the logical list of product parts and relationships
  • Structure — the hierarchy that shows how parts are arranged in levels
  • Occurrence — a specific positioned use of a part within the structure
Product Bolt Occ. 1 Bolt Occ. 2 Bolt Occ. 3

BOM is the product definition, structure is the hierarchy, and occurrence is the positioned use of a part inside that hierarchy.
