Send, Remove & Unlink Approvals in DPO
This article explains how to send an invoice for approval, remove an invoice from approval, and unlink a P.O. to re-edit locked fields like the supplier or unit price.
Send Invoice to Approval (Automated Flow)
If the invoice approval workflow has been configured in the Invoices administration settings, invoices are automatically submitted for approval once they are fully processed.
How it works:
- Once the invoice is completed and validated, it is automatically forwarded to the approval chain (if configured).
- If P.O.s are in use, linking an invoice to a P.O. will automatically send it into the approval workflow
- No manual action is required if automation is set up
