[Former Member]

Someone knows where to find the description of an IDoc means what an IDoc is suppose to do?

Thanks in advance.

HI

Idoc is a data container itu2019s not a process, these are stored in database tables and each idoc has a unique number. Idocs are independent of direction of adapt exchange. Idocs are based on EDI Standards and close to EDIFACT. Idocs can be viewed in text editor and do not contain any binary data.

Workflow is used to control and co-ordinate the sequence of steps in a business process

Idocs are of 2 types.

1. Master IDOC.

2. Communication IDOC.

Master Idoc is a temporary idoc and it is not stored in database table.

First of all master idoc is created and if it succeeds in validations, it is converted to communication idoc.

Idoc Structure is of 2 types.

1. Basic

2. Extension

A basic idoc type will have the following characteristics:

Name: Can be up to 30 characters

List of permitted segments

Hierarchy of segments

Mandatory vs. Optional segments

Maximum/Minimum Range for segments.

Information hold by IDOCS is of 3 types. They are:

Control Record: Specifies Sender & receiver information.

Data Record: Contains data to be transferred.

Status Record: Contains status of IDOC.

Format of IDOC in Control Record: EDIDC

Message Type

Idoc Structure

Direction -1 or 2 1 is for outbound & 2 is for Inbound

Port [Receiver]

Partner Number [Logical System Name]

Partner Type

Format of IDOC in Data Record: EDIDD

Segment Name - SDATA (1000)

Format of IDOC in Status Record is EDIDS.

Segments: Segments will define format and structure of data record. Segments are reusable components. Segments contains field that represent data in data record.

Segments can hold only 1000 characters of data, if it exceeds new segment will be created.

The following are segment components:

Segment Type: It is the name of segment. Starts with u2018E1u2019 for sap defined and Starts with u2018Z1u2019 for user defined.

Segment Definition: It canu2019t be >1000 bytes and starts with E2 for sap defined and starts with Z2 for user defined

Segment Documentation: Represents data dictionary documentation for each field. Starts with E3 for sap defines and u2018Z3u2019 for user defined.

Segments get created as structure in dictionary and every segment must be released. Generally Release no for outbound is 620 and 640 for inbound.

Set release means, changes are made permanent. To make any changes to released segment, first cancel the release, then make necessary changes, save then release again.

Transaction Ports: These are used to transfer idoc between r/3 systems.

File ports: These are used to transfer idocs to sub systems in form of files.

Outbound programs referred as u2018IDOC Generatorsu2019

Inbound programs called as u2018POSTING Programsu2019.

Posting programs are implemented as function modules and are generally named as u2018IDOC_INPUT_<MSG TYPE>.

Status of IDOC:

01 - Initial status.

30 - Ready for dispatch

03 - Waiting at port.

12 - Reached Destination.

Modes of Transport: Outbound & Inbound

Outbound and Inbound numbers of idoc will not be same but data is same.

Reduced Message Type: To suppress some segments of standard structure.

Extended Idocs: Adding some new segments to existing idocs.

SOLD-TO-PARTY: Customer who placed order.

SHIP-TO-PARTY: To whom goods are sent

BILL-TO-PARTY: To whom bill is sent.

Transaction codes for IDOCS:

WE32 - Idoc Views

WE60 - Documentation for Idocs

WE61 - Documentation for IDOC record types

WE62 - Documentation for IDOC segment types

VOFM- Requirements & formulas used in message controls

SM51 - List of application servers running

SM59 - To create RFC destination

WE64 - Process code in Inbound & outbound IDOC.

BD59 - To create field level filter

WE02 - Transaction for idoc list display

WE05 - Transaction for idoc list display

Hi,

Idoc is an inter medieat document ..using this we can exchange the data between two different SAp systems.

The messages exchanged between systems are of various message types. The message type depends on the data contained and the process involved. It determines the technical structure of the message, the IDoc type. For example, the FIDCMT message type is used for journal messages.

The IDoc type indicates the SAP format that is to be used to interpret the data of a business transaction.

An IDoc type consists of the following components:

· a control record

This is identical for each IDoc type.

· several data records

One data record consists of a fixed key part and a variable data part. The data part is interpreted using segments, which differ depending on the IDoc type selected.

· several status records

These are identical for each IDoc type and describe the statuses an IDoc has already passed through or the status an IDoc has attained.

what an IDoc is suppose to do?

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.

Idoc creation

IDOC Programming

There are two processes in IDOC processing one is INBOUND PROCESS( IDOC coming to the system and its handling at various stages) and the other is OUTBOUND PROCESS( IDOC is send to other system . Separate ABAP programs are written for these 2 processes and different configuration settings are required for each one .Depending upon the trigeering mechanism different programming approaches are used.OUTBOUND PROGRAMS handle the IDOC creation and INBOUND PROGRAMS handle the inbound IDOC and the data trasfer from the IDOC to the database tables.

The basic structure of all outbound programs is same. The CONTROL

record which is of TYPE EDIDC has to be filled. It contains important fields like

IDOCTP IDOC type

MESTYP Message Type

RCVPRN Recieving Partner (Destination)

RCVPRT Partner Type (it is LS i.e Logical System)

The DATA RECORD internal table which is of TYPE EDIDD has to be filled

in the same order as there are segments in the IDOC definition.

It has 2 important fields which are to be filled ,these are

SEGNAM Name of the segment

SEGDATA Data in the segment and can be upto 1000 bytes.This field

is corresponds to each data segment in the IDOC.

e.g.

DATA INT_EDIDD LIKE EDIDD OCCURS 0 WITH HEADER LINE.

DATA W_SEGDATA LIKE zsegment "custom segment zsegment

INT_EDIDD-SEGNAM = 'ZSEGMENT'

W_SEGDATA-field1 = value "taken from some table

W_SEGDATA-field2 = value "taken from some table

INT_EDIDD-SEGDATA = W_SEGDATA

APPEND INT_EDIDD

This will fill the data record corresponding to the segment ZSEGMENT . For all

segments the sam steps will be repeated until all the data corresponding to all the

segments in the idoc is filled in the internal table of type EDIDD.

There is only one control record and can be multile data records in the idoc

structure.

Which data is to be extracted from the tables to be filled in EDIDD type internal table is determined in standalone programs from the objects which are specified in the selection screen and from the object key passed to the function module in case of message control and is taken from BDCP table in case of change pointers using function modules "CHANGE_POINTERS_READ"

In case of stand alone programs and function modules based on change pointers method the function module "MASTER_IDOC_DISTRIBUTE" is used to send the IDOC to ALE layer for distribution ,in case of message control it is handled automatically by the RSNASTED program invoked by the message control.

In the WE60 I only can see the structure of the IDoc Am I missing something?

[Former Member]

WE60 - idoc documentation transaction.

Specify the idoc details you need and execute.

Then you can probe into all the details of what are all the segments, its attributes, short descriptions etc.

Thanks
