System Ports

For successful communication between Process Runner and SAP systems, various ports may have to be kept open in user’s network environment. <NN> means instance number.

For Normal ERP Connection:

• Dispatcher (GUI) - 32 <NN>
• Gateway (RFC) - 33 <NN>
• Message Server - 36 <NN>

For EP Connection Only:

• Message Server (HTTPS) - 444<NN>
• Java EE Dispatcher (HTTPS) - 5<NN>01
• Message Server (HTTP) - 81<NN>
• Java EE Dispatcher (HTTP) - 5<NN>00
• Process Runner Special Port - 9990 (can be configured to be a different port)

Notes:

1. If user has firewall between desktop and SAP server and user can connect on GUI ports but not in RFC port (via Process Runner), then user may have to allow those ports in firewall and/or use hostnames instead of IP addresses for SAP servers. We have observed that for some firewall/routers Network address translation (NATs), the absolute IP address and communication may not be successful. However, using hostnames seem to help in some network environments in such a situation.
2. Run-Only user, who does not have SAP GUI installed, may not need GUI Ports open.
