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.

How to Create the TRFC Port Definition?

Please follow the steps below to create a TRFC port destination:

Execute t-code WE21 in the SAP Command field.

Next on Ports in IDoc processing screen select the Transactional RFC option

Now click the Create button or press the F7 button to create a new TRFC port destination.

Now in the popup enter the Own Port Name option as shown in the image below.

Next, specify the port and description for the port definition.

Choose the Version for the port definition (for example IDoc record types SAP release 4.X).

Next, choose the RFC destination as shown in the image below.
