Hi Experts,
It is actually a hard job to totally understand ALE principles and operations.Would you provide me
some materials for illustrating ALE realization.
I mean the whole steps from creating logical system,IDoc types to transfer data successfully.What I
care more is the IDoc Type creation and its corresponding Inbound and Outbound Processing.So expect you can teach me the basic steps of connecting IDoc type with Inbound/Outbound Processing
Maybe I didn't express myself clearly,it is so complex.Thank you for your help

Hi Alex,
You have to understand the following points to understand the process and for practical knowledge follow the above steps.
Reward points if useful
The Outbound Process
The outbound ALE process in SAP sends data to one or more SAP systems. At a very high level, an outbound process involves four steps.
1.Identify the need for sending an IDo-c. This step can occur immediately upon creating an application document, can relate to a change to a master data object, can be user initiated, or can simply be a point in a process that necessitates the exchange of data. The outbound ALE process for the IDoc data is started.
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 a master IDoc. At this point, think of IDoc as yet another format in which a document can be represented. You know how a date can be stored in different formats, so imagine the date as a document with three components: day, month, and year. You can represent the date as MM/DD/YYYY, the standard American way. To make the information meaningful to a German business partner, though, you have to represent the date as DD.MM.YY. IDocs are based on a similar concept of representing one set of data in various ways.
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. The recipients are determined from a customer distribution model that maintains a list of messages exchanged between two systems and their direction of flow.
4Deliver the communication IDoc. This step delivers IDocs to the appropriate recipients using an asynchronous communication method. This allows the sending system to continue its processing without having to wait for the destination system to receive or process the IDoc.
The Inbound Process
The inbound process receives an IDoc and creates a document in the system. At a very high level, the inbound process can be seen as a sequence of steps
1.Store the IDoc in the database. First, an IDoc is received in the system and stored in the database. Then, the IDoc goes through a basic integrity check and syntax check. If everything is fine, the next step is performed.
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.
