Bill of materials

Estimated reading: 3 minutes 275 views

An Odoo Manufacturing bill of materials (BoM) lists the components, quantities and, optionally, the operations needed to produce or repair a product. It acts as the blueprint Odoo uses whenever that product is manufactured.

How to set up a BoM

Go to Manufacturing app > Products > Bills of Materials and click New, or open the Bill of Materials smart button from the product form in Sales, Inventory or Manufacturing.
Set BoM Type to Manufacture this Product.

Components

On the Components tab, click Add a line and select or create each component.

Use the settings icon to show extra columns: Apply on Variants restricts a component to specific variants, Consumed in Operation records which step uses it, and Manual Consumption forces an operator to confirm the quantity used.

Without confirming manual consumption, a Consumption Warning appears until the quantity is entered.

Operations

To add operations, first enable Work Orders in Manufacturing app > Configuration > Settings.

On the BoM’s Operations tab, click Add a line to open the Create Operations pop-up, and set the operation’s name, Work Center, optional variant restriction, and Duration Computation (based on tracked time, or set manually with a Default Duration).

Instructions can be attached as a PDF, a Google Slide link, or typed text; typing “/” in the text field opens formatting options.

Click Save & Close, or Save & New to add another operation. An existing operation can also be duplicated using Copy Existing Operations.

With the Quality app installed, click an operation’s list icon under Instructions to add detailed, step-by-step instructions as quality control points.

On the Steps dashboard, click New, give the step a title, set its Type to Instructions, and write the directions.

Miscellaneous settings

The Miscellaneous tab controls procurement and costing: Manufacturing Readiness decides whether the component status turns unavailable once the first operation’s components are missing, or only once every component is missing;

Flexible Consumption controls whether operators may deviate from BoM quantities; Routing picks a warehouse’s manufacturing operation type; Analytic Distribution records manufacturing cost to a chosen journal; and Manuf Lead Time and Days to Prepare Manufacturing Order set how long production and preparation take.

How to add by-products

Enable By-Products in Manufacturing app > Configuration > Settings.

On the BoM’s By-products tab, click Add a line and set the By-product, Quantity, Unit of Measure and, optionally, Produced in Operation.

Frequently asked questions

Where can I quickly access a product’s BoM?

Click the Bill of Materials smart button on the product form in Sales, Inventory or Manufacturing.

What does Manufacturing Readiness control?

Whether the Component Status shows as unavailable once the first operation’s components are missing, or only once every component is missing.

Can a BoM have more than one by-product?

Yes, unlike the main product, a BoM can list several by-products, each optionally tied to the operation that creates it.
