Purchase Request Tier Validation
This module extends the functionality of Purchase Requests to support a tier validation process.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Adds a multi-level approval workflow to Purchase Requests: requests must be reviewed and validated by assigned reviewers before they can be confirmed.
This module plugs Purchase Requests into Odoo's tier validation system, so a request can require one or more approval steps before it is confirmed.
On the Purchase Request form, the Confirm button is only shown when the request is still in draft and its validation status is neither pending nor rejected. The old To Approve button is hidden, and the status bar now shows draft, approved, done and rejected. A validation status field is added to the form so users can see where the request stands.
In the Purchase Request search view, two new filters are available: "Needs my Review", which lists requests where the current user is a reviewer and the request is not done or cancelled, and "Validated", which lists requests that have passed validation and are ready to be confirmed.
Administrators can create tier definitions for the Purchase Request model, meaning approval rules can be based on conditions and assigned to specific users or groups. A demo tier definition assigns review to the Purchase Request Manager group. The module also allows the route field to be edited while a request is under validation.
