Hi,

Here I am sending the information about idocs. Please reward for it.

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.

________________________________________

STEP 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

-System Name : ERP000

and Execute

STEP 7)goto Tcode : BD11 for Material Receiving

Material : 100-300

Message Type : MATMAS

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

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

IDOC Convertion

hi,

- IDoc (for intermediate document) is a standard data structure for electronic data interchange (EDI) between application programs written for the popular SAP business system or between an SAP application and an external program. IDocs serve as the vehicle for data transfer in SAP's Application Link Enabling (ALE) system. IDocs are used for asynchronous transactions: each IDoc generated exists as a self-contained text file that can then be transmitted to the requesting workstation without connecting to the central database. Another SAP mechanism, the Business Application Programming Interface (BAPI) is used for synchronous transactions.

A large enterprise's networked computing environment is likely to connect many geographically distributed computers to the main database. These computers are likely to use different hardware and/or operating system platforms. An IDoc encapsulates data so that it can be exchanged between different systems without conversion from one format to another.

IDoc types define different categories of data, such as purchase orders or invoices, which may then be broken down into more specific categories called message types. Greater specificity means that an IDoc type is capable of storing only the data required for a particular transaction, which increases efficiency and decreases resource demands.

An IDoc can be generated at any point in a transaction process. For example, during a shipping transaction process, an IDoc may be generated that includes the data fields required to print a shipping manifest. 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.

- 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.

thanks,

raji
