About engineering BOM management
Managing the part and design data of a product within a single structure results in a complex BOM, which is difficult to maintain, resulting in rework, delays, and losses. It is more efficient to enable independent evolution of part and design lifecycles. Teamcenter Engineering BOM address this challenge by maintaining the parts and designs as separate structures. Aligning the two structures allows you to perform BOM-driven digital mockups. The following video shows why is it beneficial to keep the design and engineering BOM separate, and later align the two to perform engineering BOM-driven digital mockups:
The engineering BOM management is a multi-domain engineering bill of materials that help you manage mechanical, electrical, electronics, software parts, and documents required for a product. The engineering BOM management further helps you align the part structure with the design, and then visualize the product structure in real-time. In Teamcenter, you can manage your engineering BOM either as an Assembly BOM or as a Usage BOM.If you want the parts not to have their independent lifecycle, instead the parts must be used based on their occurrence properties, you must use Assembly BOM. In Assembly BOM mode of engineering BOM management, the assembly parent owns the lifecycle of the child occurrences.If you want the parts to have their independent lifecycle and change control, referred to as part usages, you must use Usage BOM. In Usage BOM mode of engineering BOM management, a part usage can be revised and released independent of its parent assembly. The engineering BOM management works on the principle that every product uses parts that are drawn from a much larger master part list. You can use several Teamcenter applications that provide additional features to manage the engineering BOM data. Where do I go from here?

Business User
New user
Familiarize yourself with the engineering BOM terms used in Teamcenter. You can also look at the engineering BOM management business process.
Set an active change notice
It is recommended that you set an active change before you start creating or updating the engineering BOM data.
Manage the engineering BOM data of a product
Considering your business requirement, you can manage the engineering BOM data by creating and maintaining either a Usage BOM or an Assembly BOM.
Verify if the engineering BOM data is created correctly
Review the engineering BOM data to validate if the data is created correctly. You can compare the data, validate the alignment, and visualize structures.
Release engineering BOM data
The engineering BOM release process includes validation steps to ensure that the BOM adheres to your business rules before it is released.
