We are currently testing our processes for a planned migration from oodo version 12 to 15.
With XMLRPC, I was using the action_invoice_open function of the account.invoice model to validate my invoices. But I see that account.invoice has merged with account.move and I can no longer validate my invoices.
Could you tell me how what functions should I use to validate the invoices in odoo 15 ?
(in Developer Mode, hover over the button the User clicks).
You should also review the API calls being made when creating as Invoice via the UI to make sure you supply the correct data because this model is also used for Vendor Bills, Credit Notes and Journal Entries.
Although you can't review logs from a SaaS database, you can on your local VM or on-premise installation.
