Answer 1

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.
Select Model View and 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 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.
In the next screen that you get
Give the text of the material as NEW MATERIAL.
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).
8) 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.
        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.

and Execute --> 1 request idoc created for message type Matmas
press enter
Here Master Idoc set for Messge type MATMAS-->press Enter
1 Communication Idoc generated for Message Type
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.
2) Tcode BD50---> check the MATMAS check box save and comeback.
3) Tcode BD51---> goto IDOC_INPUT_MATMAS01 select the checkbox save and comeback.
4) Tcode BD52---> give message type : matmas press ok button.
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
ALE/IDOC Status Codes/Messages
01 Error --> Idoc Added
30 Error --> Idoc ready for dispatch(ALE Service)
then goto SE38 --> Execute the Program RBDMIDOC
29 Error --> ALE Service Layer
then goto SE38 --> Execute the Program RSEOUT00
03 Error --> Data Passed to Port ok
then goto SE38 --> Execute the Program RBDMOIND
12 Error --> Dispatch ok
Inbound Status Codes
50 Error --> It will go for ALE Service Layer
56 Error --> Idoc with Errors added
51 Error --> Application Document not posted
65 Error --> Error in ALE Service Layer
for 51 or 56 Errors do the following steps
goto WE19 > give the IDOC Number and Execute>
Press on Inbound function Module
for 65 Error --> goto SE38 --> Execute the Program RBDAPP01 then your getting 51 Error
