Hi

Application Linking and Enabling (ALE)

In this document you will learn the step-by-step procedure to setup the ALE system and go through a transaction between two clients

For our purpose we have two clients

namely Client 100 and Client 200.

System name is SAPKDC (FOR BOTH 100 AND 200 CLIENTS).

Distribution of Material Master Data Between two Systems

1) SETUP LOGICAL SYSTEM: (Note: Do Not Create This Step)

To do this follow the following steps

Execute SALE Transaction Code

On The Screen Click on Sending and Receiving Systems.

Then Click on Logical Systems.

Then Click Defining Logical Systems.

Click New Entries Button

(E.g. (LG100 sending system)

(LG200 receiving system))

Enter two logical system names and their description.

Save

Comeback to SALE Transaction Code screen.

2) Now you have to allocate the created logical systems to respective clients.( Note: Do Not Create This Step)

LG100 assign to client 100

LG200 assign to client 200

To do this, do the following.

Click Assigning Client to Logical System.

Ignore the message that comes up on the screen.

Select client 100

Click details button on the toolbar icon or press F2.

In the logical system box, enter LG100.

Click on the save Icon

Click the back button.

Now select client 200.

Click details icon or press f2.

In logical Systems box, enter LG200.

Save

Back.

Comeback to SALE Transaction Code screen.

3) Maintain RFC Destination: (TR.CODE:SM59)

(Note: Do Not Create This Step)

Click Create Button on the Screen

On the Screen Maintain RFC Destination i.e LG200.

Enter LG200 in RFC destination box.

Connection type is 3

Give a description for the RFC destination.

Maintain Technical Settings on Details on Technical Settings tab

Target Host as : SAPKDC (NOTE: Save it as a Host Name)

Maintain Logon Details on Logon/Security tab.

Language: EN.

User: MMUSER200 (This is the logon for dist.)

Client : 200

Password: MM1234.

Save.

Click on create to do the above process for Client 200 in

The client 200 system.

4) Maintain Distribution Model.(BD64). (ABAPer role starts here)

Execute Maintain distribution model directly for

creating the model.

Click on change mode button on App tool bar of the Screen.

Create Model View pushbutton on App tool bar of the Screen.

A pop screen will appear in which you specify

Short text as Distribution for MM Data.

Enter Technical Name as LGMODEL.

A popup screen will appear in which you specify

Model View as LGMODEL.

Sender as LG100.

Receiver as LG200.

Again Click on Add Message Type Pushbutton on App toolbar of the Screen.

A popup screen will appear in which you specify

Model View as LGMODEL.

Sender as LG200.

Receiver as LG100.

SAVE.

On the same screen goto Menubar and select Environment.

And then select Generate Partner Profiles , then execute it.

On the Screen specify the Logical System as LG200.

Then execute the screen.

Click back.

Again On the same screen goto Menubar and select EDIT.

Again select Model View and then select Distribute.

****LOGIN to client 200.

Execute Tr.code BD64 and again On the same screen goto Menubar and select Environment.

And then select Generate Partner Profiles , then execute it.

On the Screen specify the Model View as LGMODEL

And Specify the Logical System as LG100.

Then execute the screen.

Click back.

*******Switch back to client 100 Session.

5) Create Material using MM03 Tr.Code.

Enter the material name as LGMATERIAL

Industry sector as Mechanical Engineering

Material Type as Finished Products.

And then Click on Data Pushbutton on the App tool bar.

Select views.

In the select views box for materials check basic data 1 AND 2.

Click enter icon.

Base unit of measure as KG.

Gross Weight as 200.

Net Weight as 100.

Weight Unit as KG.

In the description area language (E) and material description.

Click Save.

Now I Created a Material in Client 100 , I want to transfer this data to Client 200.

6) Execute BD10 to transfer the material in which you specify

the material as LGMATERIAL and

message type as MATMAS (client100).

Then a Screen will be displayed in which it shows that

1 Master Idoc Generated .. Enter

1 Communication Idoc Generated..Enter.

*******LOGIN to Client 200.

7) Execute BD11 to get the material in which you specify

the material as LGMATERIAL and

message type as MATMAS (client200).

😎 Execute Tr.code MM03 and give the material as LGMATERIAL

and see that the material is displayed as it was in Client 100.

If not follow these steps.

9) Execute Tr.code WE19( for rectification of errors in client200).

Specify the Existing Idoc Number and Executes it .

A Screen is displayed in which you specify the corresponding Function Module as INPUT_IDOC_MATMAS01 and execute it.

10) Execute Tr.code MM03 and give the material as LGMATERIAL

and see that the material is displayed as it was in Client 100.

Now the Material is correctly displayed in Client 200.

11) Monitoring of IDOCS.

Transaction Codes:

IDOC Display of Status: WE 05.

IDOC Date and Time: WE07.

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.

IDOC

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.sapgenie.com/sapedi/idoc_abap.htm

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)
