It is possible to divide the error queue for invoice import so that invoices that lack or have the wrong company end up in a separate error queue. This setup is done in two steps:

1. Enable the UseUnitErrrorQueue system parameter
   Go to System Configuration - System Settings - Functions, find the UseUnitErrrorQueue parameter and enable it.
2. Add the queue to a role
   Go to Organisation - Queues - Queues and open the queue ImportErrorUnit, then add the role that should have access to the queue and click Save.
