Cannot book flights - error ar-40000

[CR1]

I'm receiving an error ar-40000 every time I try to book a flight. I can choose the flights and when I try to move forward the error shows. 

1. Does anyone know how to resolve this? 

2. If I cannot resolve this and book the flights directly from the airline, can I simply submit the receipts to my expense report?

@CR1 a Help ticket will need to be submitted to Concur Support so they can look at the logs to see what the exact issue was.

Before booking directly with the airline, I would suggest you speak with your direct manager to see if you should do that or call your company's travel agency to get the booking completed. However you end up booking, if you have an assigned company card, be sure to use that to pay for the airfare so that transaction will flow into your Available Expenses to get added to a report.
