1. Are you unsure about FNA messages?
So what is an FNA? An FNA is a message sent by CCN, an airline or a CTO when an error is detected in a message, for example an FWB or an FHL. With an increased focus on the correct transfer of electronic messages across the industry, it is important that if you receive an FNA message, it is dealt with appropriately and the data re-transmitted.
There are a number of common errors that can result in FNA's. Some of the more common errors are listed at http://www.ccnhub.com.au/faq. If you would like more information on FNA's, please contact CCN Customer Support.
