Inventor BOM Structure Types and how they behave in Vault

Technical Support

Issue:

When working with Vault how do different Inventor BOM structure types behave in Vault Professional.

Causes:

Understanding the BOM types in Inventor and Vault is important to effectively manage Vault Items and understand why an entry might be missing on the Vault BOM.

Solution:

When a structured BOM is enabled this table describes how different Inventor BoM Structure types behave in Vault Professional.

If entries are missing on the Vault item make sure that the structured BOM is enabled and all rows have a type of component that gets added to the BOM - Normal, Purchased or Inseperable. 

Inventor BOM Structure Types

Usage

Inventor Characteristics

Vault Professional Item BOM Characteristics

Normal

  • Most components in a design

  • Their placement/participation in the BOM is determined by their parent assembly

  • They are numbered and included in quantity calculations

  • They have no direct influence on their child components participation in the BOM

 

Generates an Item
 

Purchased

  • Cylinders, pistons, Hinges, Screws, Nuts, Rivets

  • The component is considered a single BOM line item, regardless if it is a part or an assembly.

  • Normal child components of a purchased assembly are included in structured parts list, and numbered, but are hidden in parts-only arts lists

 

  • Generates an Item on the Purchased component

  • Purchased component’s children do not create Items

 

Reference

  • Construction elements such as skeleton parts or assemblies in the modeling design, Customer Data

  • The component is treated as if it does not exist.

  • The component’s children are treated as if they do not exist regardless of their own structure value.

  • Are excluded from quantity, mass, or volume calculations

 

  • Does not create Items,

  • Component’s children do not create Items

 

Phantom

Not physical parts of the manufactured product in the design

  • They are ignored by the BOM.

  • They influence their children's participation in the BOM by promoting them in Structured BOM views.

  • The quantity of their children is multiplied by the quantity of the phantom component.

 

  • Does not create Items

  • Children promote / update and move up a level in the BOM

  • Quantities for children are adjusted to account for phantom parent

 

Inseparable

  • Weldments in assemblies that are glued or bonded

  • Riveted components fastened together with semi-permanent fasteners that must be destroyed to separate the components

  • Assemblies where components have been pressed fit together, such as dowel pins pressed into a part

In parts-only BOM, child components with a BOM structure of:

  • normal or inseparable are hidden

  • purchased are visible

 

  • Items create like in a Normal structure definition

  • Follows the Inventor BOM Characteristics
