Hi Folks,

I have got a project which is completly related to EDI and IDOC's.Can yopu please assist me with some material or in anyother way.How to proceed further.Your help is most helpful to me

hi murali,

IDocs:

IDocs (Intermediate Documents) are the crux of ALE. These are the documents with the help of which data is exchanged between SAP R/3 and non-R/3 systems. As the name suggests, these documents act as intermediate storage of information, which can be sent bi-directionally. Message types are responsible for creation of Idocs.

IDocs Components

Data on Internet is exchanged using data formats like IPV6 – and SAP uses a similar approach. Idocs are a well-structured medium through which data transfer takes place. Figure 3 explains the structure of Idocs.

An IDoc is made up of the following parts:

Control Record: This section contains control information regarding the Idoc. Its constituents are Sender’s name, Receiver name, Message type and Idoc type (illustrated in figure 3). The format of the control record is similar for all IDoc types.

Data Segment: It consists of a header that contains the identity of the Idoc. Its constituents include, a sequential segment number, a segment type description and field containing the actual data of the segment.

Status records: The status record shows the information regarding the already processed stages and remaining processing stages of the Idoc. It has an identical format for each IDoc type.

Idocs Structure:

Idocs support a hierarchical structure. Figure 4 shows an Idoc, starting with the header. The header has items, which in turn have sub-items. The lowest level in the hierarchy contains the text. The end of the Idoc is represented with the help of ACCUM (means accumulate) segment. Remember that an IDoc can only contain character fields.

IDOC:

IDOC is a container that can be used to exchange data between any two process.

Each iDoc is assigned a unique number for tracking and future reference.

iDoc Consist of several segments,and segments contain several fields.

iDoc contains the following three type of records...

1.One Control Record.

2.One or many Data Record

3.One or many Status record.

PORT:

Port is used in the outbound process to determine the name of the EDI subsystem program,the directory path where the idoc file will be created at the operating system level,the idoc file names and the rfc desinations.

RFC Destination:

Used to define the characteristics of communication links to a remote system on which a functions needs to be executed.

Partner Profile:

Partner profile specified the various componets used in an outbound process ( Partner number,IDoc type,message type,Port,Process code),the mode in which it communicates with the subsystem(batch or immediate) and the person to be notified in case of errors.

Message Control

Used in pricing,account determination,material determination,and output determination.The message control component enables you to encapsulate business rules with out having to write abap programs.

Process:

Setup RFC destinations SM59

Port Destinations WE21

Partner Profile WE20

Message control NACE

Purchase Order ME21

Check IDOCs WE02,WE05

Explain to me about Idoc?

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.

"EDI is described as the interchange of structured data according to agreed message standards between computer systems, by electronic means. Structured data equates to a simple and direct method of presenting the data content of a document. The method of ensuring the correct interpretation of the information by the computer system is defined by the EDI standard."

"EDI is a technique used to communicate business transactions between computer systems of different companies and organizations. Note that sometimes the EDI mechanism deployed at a company is often used to interface to other systems within the same organization."

EDI is nothing but Electronic data interchange. SAP will support EDI through Intermediate documents (IDOCS).

EDI (Electronic Document interchange) - EDI is the electronic exchange of business documents between the computer systems of business partners, using a standard format over a communication network.

EDI is also called paperless exchange.

Advantages:

Reduced Data entry errors

Reduced processing time

Availabilty of data in electonic form

Reduced paperwork

Reduced Cost

Reduced inventories and better planning

Standard means of communications

Better business process

EDI has two process

1. Outbound process

2. Inbound process

outbound process:

1.Application document is created.

2.IDOC is generated

3.IDoc is transferred from SAP to Operating system layer

4.Idoc is converted into EDI standards

5.Edi document is transmitted to the business partner

6.The Edi Subsystem report status to SAP

inbound process:

1.EDI transmission received

2.EDI document is converted into an IDOC

3.IDOC is transferred to the SAP layer

4.The application document is created

5.The application document can be viewed.
