Distribution Model

Used to model a distribution scenario.

Used to identify the systems involved in the

distribution scenario.Used to identify the messages exchanged

between the systems

7/30/2019 Ale Class II

6/20

Message Control

Cross Application technology used for output

determination.

Triggers the ALE and EDI output for a businessdocument.

Separates the logic of generating IDOCS from

application logic

7/30/2019 Ale Class II

Change Pointers

Tracks the changes made to key documents in

SAP.

Another way of distributing data through ALE

IDOC Structure

Major components in exchange of data.

9/20

Selection Programs

Implemented as function modules.

Designed to extract application data and create

master IDOCS.One selection program exists for each message type.

Selection programs design depends on the

triggering mechanism used in the process.

Filter Objects

Remove unwanted data for each recipient of data.

7/30/2019 Ale Class II

11/20

Port Definition

Used to define the medium in which documents

are transferred to the destination system.

ALE uses a tRFC port which transfers the data in

memory buffers.

12/20

RFC Destination

Logical name to define the characteristics of a

communication link to a remote system on which a

function needs to be executed.

In ALE , the RFC Destination specifies the

information required to log on to the remote SAP

system to which an IDOC is sent.

13/20

Partner Profile

Specifies the components used in the outbound

process.

A partner profile is created for each SAP systemwith which we communicate.

Partner profile consists of information like IDOC

Type, Message Type, tRFC port etc.
