ABAP Proxy problems

Hi,

I have some issues with ABAP proxies.

The situation I have is the following:

I'm sending data from an ECC 6.0 system to XI 7.0. I trigger and send the data. It leaves the ECC system ok, and comes into XI with the following error:

<i> <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

- <!-- Call Inbound Proxy

-->

- http://sap.com/xi/XI/Message/30" xmlns:SOAP=" http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

<SAP:Category>XIProxy</SAP:Category>

<SAP:Code area="ABAP">INTERFACE_REGISTRATION_ERROR</SAP:Code>

<SAP:P1>ifmmessif</SAP:P1>

<SAP:P2>CreditCommitmentNotification_Out</SAP:P2>

http://sap.com/xi/PI/FIN/Operational/Global>

<SAP:P4 />

<SAP:AdditionalText />

<SAP:ApplicationFaultMessage namespace="" />

No implementing class registered for the interface (ABAP interface, request message CreditCommitmentNotification_Out, request message, namespace http://sap.com/xi/PI/FIN/Operational/Global)>

<SAP:Retry>M</SAP:Retry>

</SAP:Error></i>

I activated/generated the proxy on ECC side.

One thing to know is that we have in the SLD XI client 001 defined as integration server and client 100 as application server as you can have only 1 integration server.

Thanks for the help!
