External System communication via RFC

[Former Member]

Hi Experts

In my landscape, sending system want to use an RFC connection to the PI via SAP java connector. In turn PI should call the RFC in the SAP System and execute the RFC and return the results.

note ; Sending system is Java based system

Is it possible to connect to PI from external system via java connector ? if so what configuration has to be done in the PI and external system.

when i checked the sender communication config , its asking for application server gateway and service.Is these needed to be configured in SAP PI or external system.

Please provide your inputs

Thanks in advance

If you are using SAP Java connector JCO then we dont need to use PI. SAP JCO itself is a middleware component. Sending application using JCO can directly contact SAP system.

if you are not using Java connector then you must use Java proxies.

Refer to the following link for more details-

Yes. There are many ways to connect to SAP from external system via PI. Since the external system is a java based then they can do java proxy on the sender side and target side RFC to connect SAP. Other option is you can host webservice using soap sender on the PI side and let the external system to consume your web service. This scenario is webservice to RFC via PI.
