IDoc basics

[Former Member]

Hi!

I would like to know, how can I set up the background settings of an IDoc interface?

Where can I set the sender function module?

Where can I set the receiver module?

Where can I assign them to the basic type?

How can they be debugged?

Thank you in advance

Hi ,,

go thru the below information.

IDOCs:

- IDOC is an Intermediate Document'. It is simply a data container used to exchange information

between any two processes that can understand the syntax and semantics of the data.

An IDOC is created as a result of executing an Outbound ALE or EDI process.

In an inbound ALE or EDI process, an IDOC serves as input to create an application document.

-When an IDOC is created in the system , an unique number(16 Digits) is assigned to it.

This number is unique with in the client.

- IDOCs are independent of the sending and receiving systems.

- IDOCs are independent of the direction of data exchange.

- In the IDOCs, data is stored in text format.

- IDOC will wait until the Remote System is Active.

*IDOC Definition Components

-

---

- Basic Idoc Type: Basic Idoc type defines the structure and format of the business document

that is to be exchanged between two systems. Basic Idoc type can refer to an SAP provided

basic IDOC type or a customer developed basic IDOC type.

- A basic IDOC type has the following characteristics:

Name : A basic Idoc type can be assigned upto a thirty character name.

List of permitted segments: The segments make up the IDOC structure.

Hierarchy of segments : The hierarchy of segments specifies the physical sequence and

any parent - child relationship in the segments.

Mandatory Vs Optional Segments : When used in the IDOC type, each segment has

an attribute that defines whether the segment is option or mandatory.

Minimum/Maximum range for each segment: It defines the maximum and minimum

number of timesa data record corresponding to a segment cn exist in an IDOC.

- Segments : A segment defines the format and structure of a data record.

Segments are reusable componets. A segment consists of various fields that represent data

in data record.

• IDOC Run time components:

-

---

- A unique IDOC number 16 digits is allocated.

- One control record is attached to the IDOC.

- Segments translate into data records.

- Status records are attached.

- Sytax rules are checked.

• IDOC Record Types:

-

---

1. Control Record : The control record contains all of the control information about an IDOC,

this information basically includes the IDOC number, sender and receiver information,

and information such as the message type it represents and the IDOC type.

- there is only one control record per IDOC.

- The stucture of the control record is the same for all the IDOCs and is defined by SAP.

- The structure of the control record is defined by the data dictionary structure EDI_DC40.

- The control record is stored in the EDIDC table.

2. Data Record : Data records contain the application data. A data record has two sections

Administrative Section and a Data section.

- The Administrative section cotain the segment name, client, IDOC number, segment number,

hierarchy level information.

- The Data section of a data record is a stram of 1000 bytes where the actual data resides.

- The data record is defined by the data dictionary structure EDI_DD40.

- Data records for IDOCs stored in the EDID4 table.

3. Status Record : Status records are attaced to an IDOC throughout the process as

the IDOC achieves different milestones or encounters an error. At every milestone a statu code,

date and time are assigned.

- Status codes 01 to 49 are reserved for OUtbound process, 50 and above are reserved for

inbound processes.

• Message Type: Identifies what type of information transformed between logical systems or partners.

Message type is not a local object type , it is transportable.

• Port : A Port defines the medium in which data is exchanged between the two systems in

the ALE process, IDocs are transferred via memory.

1. TRFC ports are used for ALE communicaion.

2. File Ports used by EDI

3. CPI-C ports used to communicate with R/2 systems.

4. Internet ports used to connect with Internet Applications.

5. ABAP-PI ports used to process data via the ABAP programming interface.

6. XML ports used to process files in XML format.

• Partner Profiles:

A partner profile has three views, which maintain different parameters for the partner.

1. The General Parameters View : Values are stored in table EDPP1.

2. The Outbound Parameters view : Values are stored in table EDP13, except for the

Message control parameter , which are stored in table EDP12.

3. The Inbound Parameters View: Values are stored in table EDP21.

• Transaction Codes :

WE31- Segment Creation

WE30 - IDOC structure

WE81 - Message type creation

WE82 - Link between Message type and IDOC type.

WE21 - Creation of POrt

WE20 - Partner Profile creation

WE19 - Test tool for IDOC Processing.

SALE - ALE (Application Linking and Enabling) settings

Hi,

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

For more information in details on the same along with the examples can be viewed on:

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

Hi,

You need to excahnge data between systems you need an interface as medium for data transfer.

IDoc also treat one of the interface options for data transfer.

Check this link

http://www.thespot4sap.com/Articles/SAP_ALE_Other_Concepts_Conclusion.asp

<b>IDOC Debugging:</b>

1) We generally go for customized IDocs if none of the SAP standard IDoc does not suit our need/business process. Creating is custom IDoc should be a very stringent process. The SAP standard IDocs should be rigorously checked (if any user exits can be of our help or IDoc extension will solve the purpose).

2) WE19 is the test tool by which we can create IDocs to see whether our functionality is working. It is mostly used to debug inbound function modules.

For outbound function module debugging you can use the following:

1) RBDMIDOC - for master IDocs configured via change pointers.

2) RSNASTED - for transaction IDocs with output/message control.

3) RSEOUT00 - For IDoc whose status is "to be processed".

<b>Reward points</b>
