Error in HTTP Connection Test(SM59) for Web Service Consumption

Hi,

My project does not have a PI Product and we are using our SOAP web services directly through SOAMANAGER and outside interfaces.

We got a WSDL from a new partner application, and after setting up the consumer proxy, when we are testing the connection at SM59(Under HTTP Connections), we are getting a status response as 415(Unsupported Media Type)

After doing a lot of research, i found out that we need to check the SOAP/HTTP Header to ensure that we are sending the request in the right format as required by the receiver. How, can we check the request or the actual response coming from an external HTTP System.

a) Is there any trace available within SAP?

b) Can SXMB_MONI be used in this case to check the XML Payload

c) What other ways do you suggest for troubleshooting this probem

Thanks

Sahil
