How to run Sharepoint WSDL on SoapUI?

Question

SharePoint

Good afternoon Colleagues. Faced such task. It is necessary to "fasten" to SAP a portal on SharePoint wsdl. But this is different. First you need to "learn" how to work with WSDL using SoapUI. Service added, methods I see. Passed authorization. But an error occurs:

Internet search says that the error is in the header of the transmitted request. It is impossible to overcome it. I added the mustUnerstand = 1 parameter to the header. It doesn't help. Tell me how to work with soapui balloon methods? what is missing?
ps judging by http log this parameter is passed
