No implementing class registered for the interface

[Former Member]

Hi,

I am getting error - ABAP INTERFACE_REGISTRATION_ERROR : "No implementing class registered for the interface" - when trying to process inbound messages.

Before this error I was getting message - "messages waiting in queue (yellow triangle" . Then i tried to register queues, after that I started getting ABAP INTERFACE_REGISTRATION_ERROR error mentioned above.

Please advice what can be done to resolve this issue.

Thanks

Rajesh

any luck on this?

No sir. I tried transaction sproxy in R3 and it says "no connection to integration builder (only generic data visible"

[prabhu_s2 · Accepted solution]

okie...this is something related to rfc. check with the rfc connection. probably the user name and pwd needs to be changed. once this is done the proxy can be activated for surpassing the error

i tried following solution also from old messages in SDN -

Go to SXMB_ADM.

Execute Integration Engine

EDIT-> Change Global configuration data

Select the Role of Business System is Integration Server

Again started getting error-PROXY_NOT_ALLOWED_ON_IS:

Proxy calls are not permitted on sender or receiver side on the IS (client)</SAP:Stack>

But again one of the messages in SDN suggests to change Global configuration data,

EDIT-> Change Global configuration data

Select the Role of Business System is Application system.

it seems it's going in loop....

In R/3 you need to have the role of Business System as Application system and not Integration Server.

hi prabhu, thanks for your quick response..can you please confirm whether i have to verify rfc in R/3 or XI

[prabhu_s2 · Accepted solution]

check in r3

Thanks a bunch. Inbound messages are getting posted into SAP.

As you suggested, I changed id and password for RFC in R/3 and saved. After that

registered queues again in XI (sxmb_adm>manage queues>register queues)

again, thanks to you all for helping me in resolving this issue.

>> "No implementing class registered for the interface"

This error means there is no server proxy created for the particular interface.

Have you created a proxy?

If so, have you made any changes to Data Type /Message Type/ Message Interface in IR? If so, you need to recreate the proxy in SPROXY.
