Differences :

ALE(Application Link Enabling) refers to the losely coupled systems whereas the EDI speaks about the Electronic Document Exchange. We need to enable ALE in order to use the EDI feature. ALE builds the bridge and EDI is the means by which the data moves in and out of the SAP system just like vehicles moving over the bridge. IDOC(Intermediate Documents) are the data containers which will be moving in and out of SAP carrying data.

Thus summarising we need to establish ALE between the systems in order to use EDI between them. In case we need to use EDI between SAP and someother target system then we need a EDI subsystem which understands these IDOCs and converts into the format understood by the target system.

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.

The philosophical difference between EDI and ALE can be pinned as follows: If we send data to an external partner, we generally speak of EDI, while ALE is a mechanism to reliable replicate data between trusting systems to store a redundant copy of the IDoc data. The difference is made clear, when we think of a purchase order that is sent as an IDoc. If we send the purchase order to a supplier then the supplier will store the purchase order as a sales order. However, if we send the purchase order via ALE to another R/3 system, then the receiving system will store the purchase order also as a purchase order.

Hi Siva,

ALE

Application Link Enabling (ALE) is a mechanism for the exchange of business data between loosely-coupled R/3 applications built by customers of SAP, the enterprise resource management program. ALE provides SAP customers with a program distribution model and technology that enables them to interconnect programs across various platforms and systems.

There are three layers in the ALE system: application services, distribution services, and communication services. The vehicle for data transfer is called an IDoc (intermediate document), which is a container for the application data to be transmitted. After a user performs an SAP transaction, one or more IDocs are generated in the sending database and passed to the ALE communication layer. The communication layer performs a Remote Function Call (RFC), using the port definition and RFC destination specified by the customer model. The IDoc is transmitted to the receiver, which may be an R/3, R/2, or some external system. If the data is distributed from a master system, the same transaction performed by the sender will be performed by the receiving system, using the information contained in the IDoc.

EDI

Short for Electronic Data Interchange, the transfer of data between different companies using networks, such as VANs or the Internet. As more and more companies get connected to the Internet, EDI is becoming increasingly important as an easy mechanism for companies to buy, sell, and trade information. ANSI has approved a set of EDI standards known as the X12 standards.

this is your IDOC

Change Pointers

I know how to change the description of a material using ALE Change Pointers.

I will give the following few steps

1) Tcode BD61---> check the change pointers activated check box

save and goback.

select all what ever you want and delete remaining fields.

save & come back.

5) 5) go to Tcode MM02 select one material and try to change the description and save it

it will effects the target systems material desciption will also changes

6) goto Tcode SE38 give program Name is : RBDMIDOC and Execute

give Message type : MATMAS and Executte

Hi,

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.

That is "EDI is a generic term meant for exchanging electronic documents between systems, typically used for exchanging documents (e.g. purchase orders) between enterprises. Two most popular standards for EDI are ANSI X12 and UN/EDIFACT. see www.disa.org for more information."

ALE (Application Link Enabling):

A means of creating and operating distributed applications.ALE guarantees a distributed, but integrated, R/3 installation. This involves business-controlled message exchange using consistent data across loosely linked SAP applications.Applications are integrated using synchronous and asynchronous communication - not by using a central database.

ALE consists of the following layers:

Application services

Distribution services

Communication services

ALE uses IDOC format to create messages, standard SAP IDOC's are compatible with ANSI X12 and UN/EDIFACT (meaning they contain all the information required for creating X12 or EDIFACT message)

For more details you can refer below links:
