Seeburger to SAP PI java stack (7.31) to ECC idoc configuration

Hi experts,

I need to connect to seeburger to ECC using SAP PI(java stack) using RFC and I need the details to be able to do this.

The restrictions are that I cannot use the ABAP stack in PI although my system is a dual stack.

I need the complete config and also the control header value for sender port and and client for the EDI_DC40 table as they do are required to be hardcoded.

I have tried going through the community and most of the things that I found did not work. Any help would be appreciated.
