Hi experts,

I am new to ALE so i want to know how many types of ALE And basic things about ALE. like configuring

ALE

Thanks and regards.

Hi,

you could find a lot of information at SAP Help:

Hi,

welcome to sdn world. as a beginer ale idocs is very important. i am proving links just give a go.

. Create a z function module for idoc inbound posting (copy from a function module idoc_input_*).

2. Set Function Modules as Inbound: - Transaction BD51

3. Assign Function Modules to Logical Messages and Idoc types:- Transaction WE57

4. Create process codes : Transaction WE42, and link the z-function module.

5. Create partner profile: transaction WE20 and attach the message type and process code

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.

How to create idoc?

*WE30 - you can create a IDOC type

http://www.erpgenie.com/sapedi/idoc_abap.htm

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 )

Creating a Segment

Go to transaction code WE31

Enter the name for your segment type and click on the Create icon

Type the short text

Enter the variable names and data elements

Save it and go back

Go to Edit -> Set Release

Follow steps to create more number of segments

Create IDOC Type

Go to transaction code WE30

Enter the Object Name, select Basic type and click Create icon

Select the create new option and enter a description for your basic IDOC type and press enter

Select the IDOC Name and click Create icon

The system prompts us to enter a segment type and its attributes

Choose the appropriate values and press Enter

The system transfers the name of the segment type to the IDOC editor.

Follow these steps to add more number of segments to Parent or as Parent-child relation

Save it and go back

Go to Edit -> Set release

Create Message Type

Go to transaction code WE81

Change the details from Display mode to Change mode

After selection, the system will give this message “The table is cross-client (see Help for further info)”. Press Enter

Click New Entries to create new Message Type

Fill details

Save it and go back

Assign Message Type to IDoc Type

Go to transaction code WE82

Change the details from Display mode to Change mode

After selection, the system will give this message “The table is cross-client (see Help for further info)”. Press Enter.

Click New Entries to create new Message Type.

Fill details

Save it and go back

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)

If (yes)

Determine Processing Program from TNAPR Table.

ELSE

Execute RSNASTED Program.

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.

7. Check for Process Immediately.

If NO

Execute RBDAPP01 Program

Read Process Code from Partner Profile

Process Code Points to Function Module

Application Document Posted.

Pls find the link below you have lot of information on ALE.

Hi,

Below are some basic points regarding ALE.

Distributed Process:

A distributed process is one in which part of a business process is carried out on one system and part on another. The two systems would exchange data with each other at appropriate points to stay synchronized.

Need for Distributed Process:

u2022 Business in Different Geographical Locations.

u2022 Non availability of dedicated network.

u2022 Cultural and language differences in Geographical locations.

u2022 Running of Mission-critical Applications (Like Maintenance downtime etc.).

u2022 Separate up gradation of Modules.

Benefits of ALE:

u2022 Integration with non-SAP systems: ALE architecture allows third party applications to integrate with SAP system.

u2022 Reliable Distribution: Once message type created and the receiver of the message is determined, ALE delivers the message to the recipient. If there is any network problem it will buffer the message and delivers the message once the network is restored. It also ensures that the message is not delivered twice.

u2022 Release Upgrade: Any of the distributed system can be upgraded to the new release of SAP without affecting the functionality. The ALE layer ensures backward compatibility of messages exchanged between systems.

Outbound Process:

ALE Outbound Process in SAP sends data to one or more SAP Systems. It involves four steps.

1. Identify the need of IDoc: This step starts upon creating a application document, can relate to a change to a master data object.

2. Generate the Master IDoc: The document or master data to be sent is read from the database and formatted into an IDoc format. This IDoc is called as a Master IDoc.

3. Generate the Communication IDoc: The ALE Service layer generates a separate IDoc from the Master IDoc for each recipient who is interested in the data. Separate IDocs are generated because each recipient might demand a different version or a subset of the Master IDoc. These recipient-specific IDocs are called Communication IDocs and are stored in the database.

4. Deliver the Communication IDoc: The IDoc is delivered to the recipients using an asynchronous communication method. This allows the sending system to continue its processing without having to wait for the destination system to receiver or process the IDoc.

Inbound Process:

The inbound process receives an IDoc and creates a document in the system.

1. Store the IDoc in the database: The IDoc is received from the sending system and stored in the database. Then the IDoc goes through a basic integrity check and syntax check.

2. Invoke the Posting Module: The control information in the IDoc and configuration tables are read to determine the posting program. The IDoc is then transferred to its posting program.

3. Create the Document: The posting program reads the IDoc data and then creates a document in the system. The results are logged in the IDoc.

Reward points if useful.
