Hi,

Port specify the medium , like File or tRFC, this is the Entry and Exit for Idocs.

Hi Bindu,

Here is extracts from saphelp.

You use the port maintenance in the IDoc adapter to establish an RFC connection to the system that contains the metadata that the IDoc adapter requires to convert IDocs (Intermediate Documents) that have been sent to it to IDoc XML format. This system is defined by the sender port and the client in the IDoc control record. It is either the sender SAP system or an SAP reference system.

The metadata comprises the IDoc structures for the corresponding IDoc types. Using this port you can call this data either directly at runtime or you can load it to the Integration Server (the system with the IDoc adapter) beforehand.

You must maintain a port in the IDoc adapter for all clients in each SAP system that you want to connect to the Integration Server using IDocs.

This is also the case for receiver systems if they are subsystems (non-SAP systems). Systems of this kind are defined using the receiver port in the respective communication channel.

Ports you mean the Trfc Ports?

Firstly there are IDOC, RFC and BAPIS which are used by the R/3 to communicate outside world, and the member in the outside world determines which one you will use....

now IDOCS only communicate using the PORTS Trfc ports so we have to create it... when two SAP Systems communicate betwwen thenself using IDOC then they have to be ports to IDOC exit and enter. Since XI is a double stack it has both the ABAP and JAVA stack, for IDOC communication you create Ports for communication betweeen them.......

you use RFC when the fuction has to be called remotley...i mean SAP or NON SAP...any one haging the capalibility to ping to that destiation whcih is created on teh TCPIP leavel communication......

RFC dest are used when the communcation happens between the remote systema and R/3 on the TCPIP level..... and so on...
