Hello Friends

I have to create ALE config from one system to another, Requirement is to transfer delivery note from one system to another.

Please could some explain the basic steps to the same.

ALE

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.

http://www.sapgenie.com/ale/why_ale.htm

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.

Changes made to fields in master data tables can be set to trigger distribution of the changes to slave systems, so that multiple database servers can update the same information simultaneously. IDocs carry information directly between SAP systems. In order to communicate with a non-SAP system, an IDoc is first transmitted to an intermediary system that translates the data to a format that will be understood by the receiver. Return data also passes through the translating system, where it is again encapsulated into an IDoc.

Also please check these online documents for ALE and IDoc.

***************************

I will explain you whole configuration step by step.

If you r communication between two sap system the configaration is as follows.

1. Enter SALE tcode in your command prompt.

There is four options available.

Go to First one which is Sending and Recieving System.

In Sending and Receving system Go to Define logical System.

You have to configure one logical system as outbound system and one system as inbound system.

2.Then goto SCC4 tcode.And assign your logical system to clients.

3.After Client assignment you have to Configure RFC Connection for this Logical systems by SM59 tcode.You have to give name same as Logical system.

4. Now u have to define port for your RFC Destianation by WE21 tcode.

your port should be file or trfc in case of sap to sap communication.

You have to do 3 & 4 step twice for Inbound(Receiver) and Outbound(Sender) logical systems.

(Only senderside)

5. Now create distributed model by BD64 tcode.You have to define your both logical system as sender and receiver over here and also specify message type.

In sap to sap system we don't require zmessage type so specify default one.

6.Now create partner profile by BD82 tcode.

7. Distributed this Model.

8.Now u can send your vendor customer material to other client as per message type.

Hi Kapil,

ALE application linking enable is used tom integrate business proceess

we can generate idocs by using 3 methods

1) executable programs

ex. bd10,send material

bd 11 get material

2)change pointers

for sendindig material master data replicated automatically in target systems

3)message control

can send transactional data

ex purchase order like

and also control their medium of exchange

go through these steps

Sending System(Outbound ALE Process)

Tcode SALE ? for

a) Define Logical System

b) Assign Client to Logical System

Tcode SM59-RFC Destination

Tcode BD64 ? Create Model View

Tcode BD82 ? Generate partner Profiles & Create Ports

Tcode BD64 ? Distribute the Model view

Message Type MATMAS

Tcode BD10 ? Send Material Data

Tcode WE05 ? Idoc List for watching any Errors

Receiving System(Inbound ALE )

Tcode SALE ? for

a) Define Logical System

b) Assign Client to Logical System

Tcode SM59-RFC Destination

Tcode BD64 ? Check for Model view whether it has distributed or not

Tcode BD82 -- Generate partner Profiles & Create Ports

Tcode BD11 Getting Material Data

Tcode WE05 ? Idoc List for inbound status codes

ALE IDOC Steps

Sending System(Outbound ALE Process)

Tcode SALE ?3 for

a) Define Logical System

b) Assign Client to Logical System

Tcode SM59-RFC Destination

Tcode BD64 !V Create Model View

Tcode BD82 !V Generate partner Profiles & Create Ports

Tcode BD64 !V Distribute the Model view

This is Receiving system Settings

Receiving System(Inbound ALE )

Tcode SALE ?3 for

a) Define Logical System

b) Assign Client to Logical System

Tcode SM59-RFC Destination

Tcode BD64 !V Check for Model view whether it has distributed or not

Tcode BD82 -- Generate partner Profiles & Create Ports

Tcode BD11 Getting Material Data

Tcode WE05 !V Idoc List for inbound status codes

Message Type MATMAS

Tcode BD10 !V Send Material Data

Tcode WE05 !V Idoc List for watching any Errors

1)a Goto Tcode SALE

Click on Sending & Receiving Systems-->Select Logical Systems

Here Define Logical Systems---> Click on Execute Button

go for new entries

1) System Name : ERP000

Description : Sending System

2) System Name : ERP800

Description : Receiving System

press Enter & Save

it will ask Request

if you want new request create new Request orpress continue for transfering the objects

B) goto Tcode SALE

Select Assign Client to Logical Systems-->Execute

000--> Double click on this

Give the following Information

Client : ERP 000

City :

Logical System

Currency

Client role

Save this Data

Step 2) For RFC Creation

Goto Tcode SM59-->Select R/3 Connects

Click on Create Button

RFC Destination Name should be same as partner's logical system name and case sensitive to create the ports automatically while generating the partner profiles

give the information for required fields

RFC Destination : ERP800

Connection type: 3

Description

Target Host : ERP000

System No:000

lan : EN

Client : 800

User : Login User Name

Password:

save this & Test it & RemortLogin

Goto Tcode BD64 -- click on Change mode button
