The error message is no longer there.

If you open Supplier Invoice ABC's General tab, you can see that 'Entry Method: External application'. Since this invoice was created by an external application, no employee (business user) was assigned to the Invoicing Unit. When the user opens the Invoice and Save it, only then, the system is able to assign the Invoicing Unit for this user. For the invoices that are created externally, the system is unable to automatically assign it. That's why this message is triggered.
For example, if the Supplier invoice was created manually, this message wouldn't be triggered. That's because the Invoicing unit would already be assigned to the creator (business user).

The system is behaving as expected.
