Hello everyone,

I'm currently facing a persistent issue in the Expenses module after migrating from Odoo 16 to Odoo 17 recently.

The problem is specifically: "The 'Vendor' field is required, please complete it to validate the vendor bill." appears when an expense is submitted/validated and attempts to create the accounting journal entry.

• Odoo Version: Odoo 17 (Community)

• Previous Version: Odoo 16, where this process worked correctly.

• Scope: The error only affects one specific user/employee. I have successfully tested the same process with another employee, and the entries posted without any issue.
