Hello,
I'm using SAP PO 7.5 Single Stack.
I'm struggling with the SOAP Receiver proxy (3.0) configuration. Here's my current configuration screen:

What I already did in ecc:
- Create RFC Type G using /XISOAPAdapter/MessageServlet?ximessage=true path
- Change the corresponding Integ. Server (/nSXMB_ADM) to the RFC type G
Here's the problem I'm facing.
1. According to document here and others, I need to use the /sap/xi/engine?type=entry as the path
but when I change it, I got the error 404 (not found)

2. But when I change it to /XISOAPAdapter/MessageServlet?ximessage=true, the error was gone but I get "user is not authorized error."

The SAP User has already been given these roles

Please advice.
Thanks
Sam
