Third party system (JCO) ---RFC--- PI ---RFC--- ECC

Question

Hello all,
We are trying to implement the following scenario:
Third party system (JCO) -RFC-> PI -RFC-> SAP ECC
The third party system connect to PI via Java Connector API with a know user id in PI. After that third party system tries to obtain the RFC that is already implemented and remote enabled in SAP ECC environment. But at this step there is something wrong in third party system software because we are not able to obtain the RFC interface and metadata from PI repository.
1. This step is working correctly. Connection is OK.
            JCO.Client mConnectionPI = JCO.createClient("100", // SAP client
                                                                                "user_id", // userid
                                                                                "********", // password
                                                                                "pt", // language
                                                                                "10.x.x.x", // application server host name
                                                                                "01"); // system number
            mConnectionPI.connect();
2. This step is not working correctly:
            JCO.Repository repository = new JCO.Repository("TestRep", mConnectionPI);
            IFunctionTemplate ftemplate = repository.getFunctionTemplate("Z_RFC_XXX"); - not found exception
We would like to know if there is something missing in any environment that we have to configure or implement in order to fix this issue. Thanks a lot.

Hi Primini,
couple of stupid-but-necessary questions:
1) have you imported the RFC model in PI Repository?
You don't need to have the RFC metadata in PI ABAP stack (there is no point in doing that), but rather in the PI Repository/ESR, within the SWCV you've created.
Check the "Activities" session of this link for more details:
http://help.sap.com/saphelp_nw70ehp2/helpdata/en/2b/a48f3c685bc358e10000000a11405a/frameset.htm
2) if you have done 1), have you configured the RFC Sender scenario properly?
I mean, have you ran the configuration wizard to create the agreements & determinations, setting the RFC interface as both the sender and the receiver interface? Of course, the systems would be different: as the sender system, you'll have a Business Service representing the legacy/JCo system; as the receiver, you'll have the ERP Business System.
This should make your scenario work.
If it doesn't, try one more thing: in the JCo code, just for the metadata repository connection, use a connection to the ERP system. But for the actual call, use the PI system.
Let us know the results.
Best regards,
Henrique.
