RFC Destination

[Former Member]

Hi,

What is the use of RFC Destination?

What is the use of each destination type?

--R/3 Connections?

--R/2 Connections?

--Internal Connection?

--Logical Destinations?

--TCP/IP Connections?

--Connections via ABAP/4 Driver?

in simple words please.

Thanks

Hi Seshu,

Check the link below... http://help.sap.com/saphelp_nw2004s/helpdata/en/22/042652488911d189490000e829fbbd/content.htm

Basically SAP supports different types of RFC connections.

Cheers

Hi,

Thanks for reply.

What is the use of LOGICAL SYSTEM?

Which topis is it related to?

Thanks

Defining Logical Systems

Use

You use this function to decide to which other clients (in your system and in external systems) you want to have an RFC connection for the Postprocessing Office.

You only need to run this function if you want to use the Postprocessing Office across all clients or systems. Each client that you want to connect is identified by a logical system. For more information, see General System Maintenance.

Prerequisites

You have set up the logical systems for which you require RFC connections. For more information on setting up logical systems, see the SAP Customizing Implementation Guide (IMG) under SAP NetWeaver ® SAP Web Application Server ® IDoc Interface/Application Link Enabling (ALE) ® Basic Settings in the section Set up Logical Systems as well as in the SAP Library under IDoc Interface/ALE.

Procedure

Specify each logical system for all systems and relevant clients that you want to connect.

Example

You are using the software components Account Management (FS-AM) and Loans Management (FS-CML) in two different logical KBICLNT500 and AENCLNT000. Both software components use the software component SAP Business Partner for Financial Services (FS-BP). This means that both systems may contain postprocessing orders for the business partner object type. To be able to display and edit the postprocessing orders for the business partner object type from Account Management also, define the logical system AENCLNT000.

This example applies only if the business partner master is synchronized in the different systems.

Hi,

where exactly we use this?

hi,

A logical system (LS) is the representation of an R/3 or

external system for distribution of data to and from the

R/3 system. Every R/3 client used for ALE or EDI has to

have a base logical system associated with the client.

This LS becomes the ‘sender’ for outbound messages, and a

‘receiver’ for inbound messages.

Hi,

RFC Destination are the gateway through with communication with other interfaces are performed from a SAP System.

Usage of Connections:

Each destination has a connection-type field (Connection type), which tells the kind of system connection:

1. R/2 connections (Type 2) -- Type 2 entries specify R/2 systems.

2. R/3 connections (Type 3) -- Type 3 entries specify R/3 systems.

3. Internal connections (Type I) -- Type I entries specify R/3 systems connected to the same data base as the current system.

4. Logical destinations (Type L) -- Instead of specifying a system connection, type L (logical) entries refer to a physical destination.

5. Connections via ABAP driver (Type X) -- Type X entries specify systems where device drivers in ABAP have been specially installed. When you create a type X entry, you must give the name of the ABAP device driver.

7. TCP/IP Connections (Type T) --- Type T destinations are connections to external programs that use the RFC API to receive RFCs.

8. Type M --- Type M entries are asynchronous RFC connections to R/3 Systems via CMC (protocol X.400).

9. Type S --- Type S corresponds to type 2, except that the destination is SNA or APPC.

RFC Destinations are used in applications of calling a remote function module, it is also mandatory in other applications like EDI, ALE,Business Workflow,etc., Since these applications involve internal and external communication, RFC Destinations are mandatory.

Reward points if convinced with my answer.
