In my DataStage jobs I am getting data from R/3 through IDOC Extract stage. The way I understand is RFC server recieves all the IDOC sent by SAP R/3 on tRFC destination and passes them to DataStage server through PSA.
Some member of security team are saying that if you RFC server is recieving only IDOC's then I do not need SAP CPIC ID for the RFC server.
I read the documentation and it seems to me that CPIC ID is needed to send the status message back. Is there any other reason for which I need CPIC ID for the RFC server. I tried starting RFC server without the CPIC ID and it gave me an error so I am assuming that there must be some other reason too.
I will appreciate your inputs on this.
Thanks,
Dinesh
Why does a CPIC ID required for RFC server to connect to R/3
