Error accessing .NET web service from SAP

Question

.NET

Good afternoon.
When calling the web service from SAP, an error occurs: SOAP:1 007 SRT: Unsupported xstream found: ("HTTP Code 405 : Method Not Allowed") The
proxy is configured, the logical port was configured both via LPCONFIG and via
SOAMANAGER Service URL - everything works.
But it is necessary that SAP add cookies to the request (mysapsso), respectively, the logical port must be configured via RFC Destination (indicating the corresponding checkbox: Assert SAP Ticket) (both manually via sm59 and automatically when creating a logical port via SOAMANAGER).
In this case, it produces the above error, although SOAP support has been added to the web.config of the web service.
At the same time, Test connection in sm59 and Ping Web Service in SOAMANAGER work.
Thanks in advance for your help.

Answer 1

I figured out that in the Path Prefix (configured via SOAMANAGER) you need to specify the path from the host to the service name inclusive.
for example: /HelloWorld/Service.asmx
Perhaps it can be solved by correct setting endpoints in web.config
If anyone knows, please tell me.
