Application Linking and Enabling (ALE)
In this document you will learn the step-by-step procedure to setup the ALE system and go through a transaction between two clients
For our purpose we have two clients
namely Client 100 and Client 200.
System name is SAPKDC (FOR BOTH 100 AND 200 CLIENTS).
Distribution of Material Master Data Between two Systems
1) SETUP LOGICAL SYSTEM: (Note: Do Not Create This Step)
To do this follow the following steps
Execute SALE Transaction Code
On The Screen Click on Sending and Receiving Systems.
Then Click on Logical Systems.
Then Click Defining Logical Systems.
Click New Entries Button
(E.g. (LG100 sending system)
(LG200 receiving system))
Enter two logical system names and their description.
Save
Comeback to SALE Transaction Code screen.
2) Now you have to allocate the created logical systems to respective clients.( Note: Do Not Create This Step)
LG100 assign to client 100
LG200 assign to client 200
To do this, do the following.
Click Assigning Client to Logical System.
Ignore the message that comes up on the screen.
Select client 100
Click details button on the toolbar icon or press F2.
In the logical system box, enter LG100.
Click on the save Icon
Click the back button.
Now select client 200.
Click details icon or press f2.
In logical Systems box, enter LG200.
Save
Back.
Comeback to SALE Transaction Code screen.
3) Maintain RFC Destination: (TR.CODE:SM59)
(Note: Do Not Create This Step)
Click Create Button on the Screen
On the Screen Maintain RFC Destination i.e LG200.
Enter LG200 in RFC destination box.
Connection type is 3
Give a description for the RFC destination.
Maintain Technical Settings on Details on Technical Settings tab

Maintain Logon Details on Logon/Security tab.
Language: EN.
User: MMUSER200 (This is the logon for dist.)
Client : 200
Password: MM1234.
Save.
Click on create to do the above process for Client 200 in
The client 200 system.
4) Maintain Distribution Model.(BD64). (ABAPer role starts here)
Execute Maintain distribution model directly for
creating the model.
Click on change mode button on App tool bar of the Screen.
Create Model View pushbutton on App tool bar of the Screen.
A pop screen will appear in which you specify

If not follow these steps.
9) Execute Tr.code WE19( for rectification of errors in client200).
Specify the Existing Idoc Number and Executes it .
A Screen is displayed in which you specify the corresponding Function Module as INPUT_IDOC_MATMAS01 and execute it.
10) Execute Tr.code MM03 and give the material as LGMATERIAL
and see that the material is displayed as it was in Client 100.
Now the Material is correctly displayed in Client 200.
11) Monitoring of IDOCS.
Transaction Codes:
IDOC Display of Status: WE 05.
IDOC Date and Time: WE07.
Outbound:
Step 1.  Application document is created when transaction is saved.
         2.  Message control is invoked.
         3.  Messages are processed by system.
         4.  Messages are Edited (if desired).
         5.  Output (ALE /  EDI) is checked
         6.  Validate against Message control record from Partner Profile
         7.  Application Document is saved.

idoc:
Data Creation in Idoc
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system. Instead of calling a program in the destination system directly, the data is first packed into an IDoc and then sent to the receiving system, where it is analyzed and properly processed. Therefore an IDoc data exchange is always an
asynchronous process. The significant difference between simple RFC-calls and IDoc data exchange is the fact, that every action performed on IDocs are protocolled by R/3 and IDocs can be reprocessed if an error occurred in one of the message steps.
While IDocs have to be understood as a data exchange protocol, EDI and ALE are typical use cases for IDocs. R/3 uses IDocs for both EDI and ALE to deliver data to the receiving system. ALE is basically the scheduling mechanism that defines when and between which partners and what kind of data will be exchanged on a regular or event triggered basis. Such a set-up is called an ALE-scenario.
IDoc is a intermediate document to exchange data between two SAP Systems.
*IDocs are structured ASCII files (or a virtual equivalent).
*Electronic Interchange Document
*They are the file format used by SAP R/3 to exchange data with foreign systems.
*Data Is transmitted in ASCII format, i.e. human readable form
*IDocs exchange messages
*IDocs are used like classical interface files
IDOC types are templates for specific message types depending on what is the business document, you want to exchange.
WE30 - you can create a IDOC type.
An IDOC with data, will have to be triggered by the application that is trying to send out the data.
FOr testing you can use WE19.

An IDoc is simply a data container that is used to exchange information between any two processes that can understand the syntax and semantics of the data...
1.IDOCs are stored in the database. In the SAP system, IDOCs are stored in database tables.
2.IDOCs are independent of the sending and receiving systems.
3.IDOCs are independent of the direction of data exchange.
The two available process for IDOCs are
Outbound Process
Inbound Process
AND There are basically two types of IDOCs.
Basic IDOCs
Basic IDOC type defines the structure and format of the business document that is to be exchanged between two systems.
Extended IDOCs
Extending the functionality by adding more segments to existing Basic IDOCs.
To Create Idoc we need to follow these steps:
Create Segment ( WE31)
Create Idoc Type ( WE30)
Create Message Type ( WE81)
Assign Idoc Type to Message Type ( WE82)

EDI:
Electronic Data Interchange
Cross-company exchange of electronic data (for example business documents) between domestic and international business partners who use a variety of hardware, software, and communication services. The data involved is formatted according to predefined standards. In addition to this, SAP ALE technology is available for data exchange within a company.

EDI FLOW :
Here is some thing which helps you and here the purchase order is taken as example too..
Electronic Data Interchange, or EDI, is the electronic exchange of business data. Using a standard format, EDI provides a method of transmitting business data from one computer to another, without the need to re-key data. This electronic link can result in more effective business transactions. With EDI, paper documents such as invoices can be replaced with electronic transmissions, thus time is saved, and the potential for error is minimized. Data can be exchanged at any time. Related business expenses, such as postage, printing, phone calls, and handling, can also be significantly reduced. EDI can aid in the support of manufacturing efforts, such as Just-in-Time and Third Party Warehousing, and financial efforts, such as Electronic Payments.
What parts of the business cycle can be supported by EDI?
Any business documents that are currently exchanged using paper can be converted to an EDI. Standards. Standards include ANSI X12 and XML/EDI are primarily used in the United States, while EDIFACT is used in Europe and Asia.
How does EDI get started?
EDI gets started when one company contacts another expressing interest in trading business documents electronically using Electronic Data Interchange. The two companies must first determine each other's EDI capabilities. If you do not already know your EDI capabilities, we have prepared a questionnaire to help you determine them. If you are already EDI capable, we will coordinate with your technical staff to determine a testing plan. Upon completion of testing the EDI documents, the appropriate business personnel will set a production start date to begin the exchange of EDI business data. If you are not EDI capable, we recommend you first obtain a commitment from your upper management. Your company will need to allocate resources and capital for software, hardware, testing, possible programming, and training.
What is the flow of EDI?
The flow of EDI depends on the sophistication of your systems and your EDI software. If you have internal purchasing/order entry systems, you will need interface programs that can extract and insert data out of and into these systems. EDI programs that interface with your internal systems are preferred over software that requires re-keying of data. Embassy Software specializes in seemless interface between EDI and your back office systems. Using a purchase order as an example of a business document your customer would send that PO electronically (850) to you. It could be sent either through a VAN (Value Added Network) or through an FTP server. You would take that 850 and convert it either into and ODBC database, a flat file or XML document to be imported into your Order System with the use of EDI Software such as PassportXchange.. Using EDI communication software, which is part of the PassportXchange package you would pull down data at set intervals from the VAN or FTP. These documents are then processed through EDI translation software and output to our order entry system. Finally, an EDI document called a functional acknowledgment (997) is sent to your customer.
