Instead of using Webservice protocol you can also use Web/HTTP protocol. In web script you can use web_custome_request function to call the web service.
web_add_header("SOAPAction", "SoapAction from SOAP UI RAW TAB");
web_set_sockets_option("SSL_VERSION", "TLS"); - **Use this header if your communication is secure (Hypertext Transfer Protocol Secure HTTPS)
lr_start_transaction("Transaction_Name");
web_custom_request("CBP1_01_Transaction_Name",
"URL=URL_HERE",
"Method=POST",
"Resource=0",
"RecContentType=application/soap+xml",
"TargetFrame=",
"Mode=HTTP",
"EncType=text/xml; charset=utf-8",
"Body=PAST YOUR REQUEST BODY "
, LAST);
lr_end_Transaction("",LR_AUTO);
let me know if you face any problem.
Thanks,
