21.3. ERROR

Means that request was not sent to supplier (supplier temporally unavailable or failed data verification) or GP Travel HUB receives incorrect response or error from supplier. In case of error GP Travel HUB additionally returns original text from supplier.

Either there can be errors returned by GP Travel HUB itself. It mostly can be cases when a request validation not passed. Requests with incorrect format can not be processed by GP Travel HUB and passed to suppliers, so GP Travel HUB returns SOAP error message.
