XI Idoc outbound record mapping

Hi,

I created proxy to IDoc interface.

All the data are being converted into IDoc format through IDoc adapter.

Now, I am considering another interface which is for data monitoring.

The interface flow is like below.

1. send data to XI (proxy)

2. mapping proxy to IDoc (IDoc adapter)

3. send a IDoc to R/3 1 (IDoc)

4. mapping IDoc to rfc

5. send a rfc data to R/3 2 (rfc)

In the step 4, I need to map IDoc's control records, created automatically by IDoc adapter, to fields in rfc.

But I have no idea how to use outbound record for mapping.

Please help me to resolve the issue.

Thanks in advance.

Regards,

Andrew
