Read the fields again after a correction

If accounting rejects an invoice, the person who uploaded it corrects it, for example with a new version from the vendor. Then the AI reads the fields of the current version again. What it reads differently appears on the document as a suggestion that a person accepts or dismisses; the AI changes no field itself. Then accounting approves again.

The workflow

The workflow starts for every document of the type incoming-invoice. Its file workflow.yaml:
