How to fix posting exception – Transport Code (….) Is Invalid

When posting invoices you may encounter the error “transport code is invalid”. It is very unlikely that you will but if you do, it is most likely due to a route (transport) code being deleted or changed after an order has been entered.

To fix this exception you will need to set up the route code again as before and then post the invoice. For more information on how to set up a route code follow this link.
