The Bill of Materials (BOM) is a list of all the components for a product or assembly. Often, the BOM is a flattened and consolidated view that lists the number of components used in the product or assembly.

Initially, the BOM is based on a Masterdata and created from a model or drawing assembly structure. However, some Masterdata items such as glue exist in the BOM but not the model or drawing assembly structure.

The BOM has many uses: you may want to create a BOM report in Excel for the purchasing department or add a BOM table to an Creo Elements/Direct Annotation drawing for the manufacturing department to use.

Understand BOM quantities - A BOM displays three quantities of parts: Modeled, Actual, and Spare.

Create (scan) a BOM:automatically - Use Scan to create a BOM based on the Masterdata and the model or drawing structure.

Create a BOM: manually - Create a new Masterdata and underlying structure.

Edit a BOM - Use the BOM Editor to refine the BOM structure, quantities, and other properties, and to generate reports.

Split a part in the BOM - Split a part to represent it as multiple line items in the BOM.

Reconcile an existing BOM with a model - Use Scan BOM to compare a manually created BOM with Masterdata from a drawing or model.

Manage BOM position numbers - Order BOM items and assign position numbers.

Generate a BOM report - Create a consolidated or structured report in the BOM Editor.

Work with BOM versions - View, open, or save BOM versions.

Compare BOM versions - Compare the differences between BOM versions.

Create a BOM Checkpoint - Save a BOM at a particular point in time, called a checkpoint. Open the checkpoint at any time to compare it with your current BOM.

Create BOM flags and tables - Use a BOM report in your drawing.

Customize BOM flags and tables - Add text references to your BOM flags and tables.
