The SOAP service you're contacting is complaining about the soap request you're sending, so turn on soap debugging with pretty-printed xml , compare to an example of soap the service is expecting, and adjust your SOAP::Data calls to generate the correct request

SOAP::Simple is simpler, see Re^11: Soap::Lite and Complex Types with WSDL
