I have automation to update traveler profile unused ticket information and am receiving an error for some records.  The error is the carrier supplied for a ticket could not be found in the database.  Is this a database that I need to maintain or is this a Concur database?  Is there an API for validating carriers?

Invalid carriers from my testing (may be others): SS, WF, BT

Error(s):

W003-ValidCarrier value could not be found in the database.-b1b345bb-5a0c-402d-822c-7c404a6daa9d

I can provide partner application client ID if needed.
