What is the Port in SAP?

The Ports in SAP are the communication channels that are used to send IDocs. We can say that the ports are the technical link between the sending and receiving systems.

The driver can be configured to support a connection via a TRFC port or to consume IDocs distributed via a File port. The default driver configuration assumes that you use the TRFC port configuration.

  • TRFC Port Definition: If the SAP users want to distribute data to multiple drivers, then each driver must have a unique TRFC port.
  • File Port Definition: If the SAP users want to distribute data to multiple drivers, then each driver must have a unique file port.
