Hi Akash,
<b>Application Linking Enabling - Purpose:</b>
<b>Application Link Enabling (ALE)</b> supports the distribution of business functions and processes across loosely coupled R/3 Systems. Connections from R/2 and non-SAP systems are supported.
<b>Implementation Considerations:</b>
Distributing business applications and at the same time ensuring data consistency is practical because:
The increasing globalization of markets has led to the physical division of organizational units.
Business processes are not restricted to one organization only and an increasing number of customers and vendors are involved.
The performance of an R/3 System can be improved by distributing the business applications.
<b>Features:</b>
ALE supports the configuration and operation of distributed applications. ALE supports the configuration and operation of distributed applications. ALE handles the Message Exchange
Between Distributed Applications across loosely coupled R/3-System, ensuring that data is always consistent.
Applications are integrated using a local database rather than a central one. There is no data retention. ALE ensures data is distributed and coordinated using asynchronous communication. ALE uses synchronous connections for reading data.
ALE supports:
?
Distribution of applications between different releases of R/3 Systems
Continued data exchange after a release upgrade without requiring special maintenance
Customer-specific extensions
Communication interfaces that allow connections to non-SAP systems
Coupling of R/3 and R/2 Systems
ALE has functions for controlling messages flows (Audit) and for eliminating malfunctions.
ALE and R/3 Procedure Model:
The R/3 Procedure Model provides cross-application information required for implementing R/3 software. The model is like a phase model whereby work steps are assigned to each phase and one or more Customizing works steps are associated with each phase.When implementing ALE functions you should refer to the R/3 procedure model to ensure that R/3 is implemented in a well structured way.
If ALE is to be supported in an R/3 System installation, implementation of the R/3 procedure model is affected at four points:
?Determining functions and processes
Specifying global settings
Modeling company structure
Modeling control data and master data
If ALE business processes are supported, functions and processes must be defined on a cross-system basis. The message types exchanged between the systems are described in the distribution model. When defining organizational units like company codes and plants in the R/3 System, it is important to note that these have to be unique worldwide, across all systems. For example, the plant 0001 can only exist in one R/3 System.
Message Exchange between Distributed Applications:
Purpose:
The basis for distributing application functions is asynchronous message exchange via ALE outbound and inbound processing.
Prerequisites:
Data exchange is based on IDoc. IDoc are created and dispatched by message types and by methods in distributed systems.
Process Flow:
An application creates a master IDoc containing the relevant data. The IDoc is passed to the ALE layer where it is prepared for dispatch. After the IDoc has been successfully transferred it is read by the target system and inbound processing is triggered. The data is processed either fully automatically or part manually according to the settings until is posted in the application.
Inbound and outbound processing can either be carried out for each individual IDoc or by massprocessing, whereby several IDoc are bundled together in one packet and processed in one step.
IDoc Definition:
An intermediate document (IDoc) is a container for exchanging data between R/3, R/2 and non-SAP systems.
Use:
ALE uses IDoc to exchange data between logical systems. Non SAP-systems can use IDoc as the standard interface for data transfer. IDoc are created by message types and (object) methods when data is to be distributed.
Structure:
An IDoc represents a configuration of an IDoc type that determines the IDoc structure. An IDoc consists of a header, several data segments and status records.The functions of the individual elements of an IDoc are as follows:
The contents, structure, sender, receiver and current status of the IDoc are defined in the IDoc header.
Each data segment contains a standard header consisting of a sequential segment
number, a description of the segment type and a 1000 character long string field
containing the actual data of the segment.
?The status records show the history of the processing steps applied to the IDoc so far.
The structure of the IDoc is recorded in the SAP System. The structure definition covers the
following:
The segment sequence. Hierarchical relationships between segments are possible.
The number of times a segment can occur is specified for each segment, as is
whether the segment is a mandatory segment or an optional segment.
The fields contained in a segment. In the example shown above the IDoc contains a
header segment that has to be the first segment of the message.
Thereafter there must be at least one additional item. The following conditions apply:
Each item must be followed by at least one sub-item and at most 99
Up to 9999 text segments can appear after an item's sub-items (optional)
The last segment in a message must be an accumulation segment (ACCUM)
An IDoc can only contain character fields.
Modeling Distribution:
Purpose:
To implement the distribution of business application processes and functions using ALE you need to construct a logical Distribution Model of the whole system. Within the framework of this configuration customers can specify what applications are to run on what systems and what messages are to be exchanged between the applications .
Distribution Model:
Definition: The distribution model describes the ALE message flows between logical systems.
Use:
You can specify the relationships between logical systems, message types, BAPIs and filters inthe distribution model. Applications and the ALE layer use the model to determine the receivers and to control data distribution.
Structure:
In the distribution model you can specify the messages to be sent to a logical system. You can also define requirements for message content and dispatch in the Filters. The distribution model consists of one or more views that you can define. With more complex distribution tasks you can assign business sub-areas or groups of logical systems to separate views. To ensure correct functioning the relevant views of the distribution model must be available in all the logical systems involved in ALE. You can find the functions for distributing views in Customizing for ALE.

Hi
Creation of Custom IDOc type and message Type
First Create Partner Profile(WE20 Tcode) and Port Definition in WE19 Tcodes.
take the Basis help to create them.
1.First create segments in WE31 Tcode with the required dataelements
2.Create the Basic Idoc Type in WE30
release the Segments and IDOC type.
3.Create Message type in We81
4.Assign the message type to IDOC type in WE82 T code
5.Create the process code in We41 (for Outbound) WE42 (for Inbound)
6.Create A fun module in SE37 starting with ZIDOC_OUTPUT_.. by copying some Inbound (for Inbound) Outbound Fun module
7.Create Workflow setting if needed ..
8. Assign the fun module to Idoc Type, Message Type and WF object (if it is there0
9.Define setting for fun module in BD51
10.In BD51 Define the settings for Fun module..
10.Assign the Processs Code to Fun mod`ule
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.
8. Entry NAST table is created for every selected output program
along with Medium & Timing.
9. Check for Process Immediately .
If (yes)
Determine Processing Program from TNAPR Table.
ELSE
Execute RSNASTED Program.
10. Read Partner Profile to determine Process Code.
11. Process Code points to the Function Module & Invoked.
12. IDoc is generated.
13. Check for ALE Request.
if (Yes)
Perform Filters, Conversions, Version Changes etc.
Else.
IDoc is stored in DATABASE.
INBOUND:
Step 1. EDI Subsystem creates an IDoc file from EDI Messages
2. Subsystem calls Functional Module EDI_DATA_INCOMING from startRFC program.
3. Data in Control Record is validate against the Partner Profile.
4. IDoc is generated in Database and syntax check is carried out.
5. IDoc file is deleted once file read.
6. Event PROCESSSTATE REACHED is triggered in Idoc Object Workflow.
7. Check for Process Immediately.
If NO
Execute RBDAPP01 Program
Else
Read Process Code from Partner Profile
Process Code Points to Function Module
Application Document Posted.
