Inbound proxy HTTP 500 Internal Server Error SAP PO

[ramu_g4]

Hi Experts,

We are working on HTTP(Axis) to Proxy(SOAP-XI) synchronous scenario in SAP PO 7.5 single stack.

Only some of the requests are getting back response messages and remainig are getting failed with following error like shown in screenshot below. But, we do not get error(but only delay in secs) while trying to send same failed request messages from SPROXY tcode of backend. But, issue is occuring in such a way only some of the synchronous requests are getting failed in SAP PO.

Could you please guide to resolve this issue and let us know how to find root cause of this issue.

Regards

Ramu

Hello Ramu, 

You can trace the Request/Response by following the steps in KBA 2107261 Information Required for PI SOAP Adapter Issues by SAP Support -> point 4. 
"SAP Note 1904944 Client side HTTP tracing for PI SOAP receiver adapter, offers another option for collecting client side (SOAP Receiver) as this is easier to setup than TCP Gateway or another sniffing tool.
Additional info on using this option available in the blog - HTTP tracing in SOAP receiver adapters with TraceHTTP module parameter"

Use the module parameter TraceHTTP with value: plain and check the mentioned traces after the error has occurred. This should give you further insights as to why the particular response is returned. 

Regards
Mark
