Inventory Part Revisions

Summary:

• An inventory part can have multiple revisions, but only one revision is active at a time.
• Revisions are managed through the Part Revision and Part Revisions pages.
• This functionality allows you to track changes to a part (e.g., design updates, material changes) while maintaining continuity in inventory and transactional data.

This is especially useful in manufacturing and supply chain environments where parts evolve over time, but you want to retain historical data and maintain links to other records like sales parts, BOMs, and routings.

In the Part Revision page for each part number, you can see the engineering change orders associated with the part, including the source of the change order and the date that the change order was made. Any ECO information will be transferred automatically when a part revision is created by an engineering transfer. You can also manually enter engineering change orders for the selected part.

Prerequisites:
An inventory part must exist.

System Effects:
As a result of this activity a new revision of the inventory part is created.

If the revision number of the new inventory part revision starts with the prototype part revision prefix that is defined for the site, also a product structure header of type Prototype is created for the new inventory part revision.

Hi ​@hmccabe,

An Inventory Part Revision allows you to manage changes to an existing inventory part without creating a new part number. Let's say you have a product A, which contains B as its component. After some time, you decide to manufacture A using C. Instead of creating another part and defining a new BOM, you can simply create a new revision, adding component C as the material. You can add a phase in date for the new revision and phase put the old one. 
In this way you can maintain traceability, lifecycle management, and maintaining accurate records of parts in manufacturing and supply processes.
