Establish Connection between the SAP Feeder System and SAP GTS

The content of the SAP GTS system mirrors the feeder system, which means whatever master data and transactional data are created in the feeder system (ECC or S/4 Hana), are transferred to SAP GTS with the help of PI and RFC. Similarly, the feeder system gets status messages from GTS with the help of an RFC connection. So we have to establish a connection between the SAP Feeder System and SAP GTS.
