Inbound proxy -> INTERFACE_REGISTRATION_ERROR

[Marcal_Oliveras]

Hello,

I know that there are multiple threads about this error but I'm not able to find the solution for my issue.

I've created the proxy in R3 (version 6.0) for a Service Interface from PI (v. 7.1). Then I've implemented the method and I've tested it first from SAP PI and then from the R3 SPROXY itself. And all the time is giving me the same error with that text:

No implementing class registered for the interface (ABAP interface, request message SI_TEST_IN, request message, namespace http://XXXXXXXXXX)

I'm sure that it has nothing to do with PI because I get the same error when I test de proxy from R3, so something is going wrong when I generate the proxy or when I implement the inbound code... but what can it be?

Thank you Gabriel,

It works changing the interface pattern from stateless to stateless (xi 3.0 Compatible).
