i know that there are tRFC,ABAP,and XML ..etc..But i want to know what is the purpose of each Port type..

points will be rewarded..

Ports are a fundamental requirement for communicating by means of the IDoc Interface

Using the port version, you inform the SAP System of the release status of the receiving system.

HI ,

Please find here withyou the purpose of these Port types.

File Interface -

---

>

Exchange of IDocs and status records via operating system files

Transactional RFC -

---

>

To set up the communication, a series of steps are required that you have to carry out in Customizing for ALE (Transaction SALE).

CPI-C ---> Link to R/2 System: Direct communication with an R/2 System (from version 5.0F onwards) is only possible using this port type.

The CPI-C protocol used by SAP is a modification of the original IBM CPI-C.

The CPI-C protocol combines the LU 6.2 commands to form a limited number of commands that can be easily used in programming (hence the name CPI-C = Common User Programming Interface - Communication). Communication takes place via a gateway which recognizes the SNA architecture and assigns the symbolic name of the target system to a logical unit in a sideinfo file.

Programming Interface (PI) ---> The IDoc is not exchanged with an external system but rather with a function module you have written. This means that any dispatch type can be used.

Use the function module to be called (for IDoc outbound processing) or the calling function module (for IDoc inbound processing). This function module can be programmed to contain the required processing. Only the interface is already defined.

XML -->

IDocs in XML format can be displayed immediately with the corresponding Internet browser. Electronic Commerce in particular uses XML, but classical EDI applications should also be XML compatible.

XML File & XML HTTP

Hi,

Maintaining Ports

Use

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.

Types of Ports:

Go to the T-Code WE21. Frm there u can find.

TRFC, FILE, CPI-C, ABAP-PI, XML FILE, XML HTTP.
