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.

• Initial Check: Based on some online searches (related to private address/contact info being missing), I verified the affected employee's private information (address, contact details) is fully populated on their private contact card. Despite this, the error persists.

Has anyone encountered this specific user-related issue in Odoo 17 after migrating? It seems to be a data-integrity or user-specific configuration problem rather than a module-wide bug.

Thank you in advance for your help!
