About IDoc Basics

[Former Member]

Hi,

I am learning IDocs. But I am getting confused with basic concept only. Can any one clear me following points in simple manner:

1. What is Inbound proceesing? In which senario we use it?

2. What is Outbound proceesing? In which senario we use it?

3. What do you mean by Triggering through Standalone programs?

4. What do you mean by Triggering through change pointers?

If you give example for each point it will be very helpful for me to understand.

Great help will be rewarded.

Thanks,

Madhura.

Data Creation in Idoc

IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system. Instead of calling a program in the destination system directly, the data is first packed into an IDoc and then sent to the receiving system, where it is analyzed and properly processed. Therefore an IDoc data exchange is always an

asynchronous process. The significant difference between simple RFC-calls and IDoc data exchange is the fact, that every action performed on IDocs are protocolled by R/3 and IDocs can be reprocessed if an error occurred in one of the message steps.

While IDocs have to be understood as a data exchange protocol, EDI and ALE are typical use cases for IDocs. R/3 uses IDocs for both EDI and ALE to deliver data to the receiving system. ALE is basically the scheduling mechanism that defines when and between which partners and what kind of data will be exchanged on a regular or event triggered basis. Such a set-up is called an ALE-scenario.

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.

An IDoc is simply a data container that is used to exchange information between any two processes that can understand the syntax and semantics of the data...

1.IDOCs are stored in the database. In the SAP system, IDOCs are stored in database tables.

2.IDOCs are independent of the sending and receiving systems.

3.IDOCs are independent of the direction of data exchange.

The two available process for IDOCs are

Outbound Process

Inbound Process

AND There are basically two types of IDOCs.

Basic IDOCs

Basic IDOC type defines the structure and format of the business document that is to be exchanged between two systems.

Extended IDOCs

Extending the functionality by adding more segments to existing Basic IDOCs.

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)

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.

Try this..Hope this will help.

Steps to configuration(Basis) >>

1. Create Logical System (LS) for each applicable ALE-enabled client

2. Link client to Logical System on the respective servers

3. Create background user, to be used by ALE(with authorizaton for ALE postings)

4. Create RFC Destinations(SM59)

5. Ports in Idoc processing(WE21)

6. Generate partner profiles for sending system

The functional configuration(Tcode: SALE)

• Create a Customer Distribution Model (CDM);

• Add appropriate message types and filters to the CDM;

• Generate outbound partner profiles;

• Distribute the CDM to the receiving systems; and

• Generate inbound partner profiles on each of the clients.

Steps to customize a new IDoc >>>

1. Define IDoc Segment (WE31)

2. Convert Segments into an IDoc type (WE30)

3. Create a Message Type (WE81)

4. Create valid Combination of Message & IDoc type(WE82)

5. Define Processing Code(WE41 for OUT / WE42 for IN)

6. Define Partner Profile(WE20)

Important Transaction Codes:

SALE - IMG ALE Configuration root

WE20 - Manually maintain partner profiles

BD64 - Maintain customer distribution model

BD71 - Distribute customer distribution model

SM59 - Create RFC Destinations

BDM5 - Consistency check (Transaction scenarios)

BD82 - Generate Partner Profiles

BD61 - Activate Change Pointers - Globally

BD50 - Activate Change Pointer for Msg Type

BD52 - Activate change pointer per change.doc object

BD59 - Allocation object type -> IDOC type

BD56 - Maintain IDOC Segment Filters

BD53 - Reduction of Message Types

BD21 - Select Change Pointer

BD87 - Status Monitor for ALE Messages

BDM5 - Consistency check (Transaction scenarios)

BD62 - Define rules

BD79 - Maintain rules

BD55 - Defining settings for IDoc conversion

WEDI - ALE IDoc Administration

WE21 - Ports in Idoc processing

WE60 - IDoc documentation

SARA - IDoc archiving (Object type IDOC)

WE47 - IDoc status maintenance

WE07 - IDoc statistics

BALE - ALE Distribution Administration

WE05 - IDoc overview

BD87 - Inbound IDoc reprocessing

BD88 - Outbound IDoc reprocessing

BDM2 - IDoc Trace

BDM7 - IDoc Audit Analysis

BD21 - Create IDocs from change pointers

SM58 - Schedule RFC Failures

Basic config for Distributed data:

BD64: Maintain a Distributed Model

BD82: Generate Partner Profile

BD64: Distribute the distribution Model

Programs

RBDMIDOC – Creating IDoc Type from Change Pointers

RSEOUT00 – Process all selected IDocs (EDI)

RBDAPP01 - Inbound Processing of IDocs Ready for Transfer

RSARFCEX - Execute Calls Not Yet Executed

RBDMOIND - Status Conversion with Successful tRFC Execution

RBDMANIN - Start error handling for non-posted IDocs

RBDSTATE - Send Audit Confirmations

FOr testing you can use WE19.

You can directly create an iDoc using some transaction like...

Use TCODE bd10 - to Send Data

and TCODE bd11 - to Get Data

and you can check the IDoc List using TCODE we02.

As you want step by step procedure.

1. Define Logical System and Assign Logical System

TCODE sale

2. Define RFC

TCODE sm59

3. Define Port

TCODE we21

4. Define Partner Profile

TCODE we20

5. Define Distribution Model

*Inbound Processing:-*

1) INBOUND PROCESS( IDOC coming to the system and its handling at various stages).

2) OUTBOUND PROCESS( IDOC is send to other system )

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

Basic structure of an OUTBOUND PROGRAM

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.

3) Triggering Via Stand alone programs

Generally used for Master Data transfer and as such depending upon the requirement can have different interfaces.The programs have a selection screen which has select options to select the objects, and parameters for specifying the recipient Logical System and the Message Type.

Data is selected based on the specified objects from the tables . and control record of type EDIDC is created and filled with important values like DIRECTION ,IDOCTP,RCVPRT,RCVPRN and MESTYP .

Data is filled in an internal table of TYPE EDIDD according to segment definitions

and in same order and the function module MASTER_IDOC_DISTRIBUTE is called passing the control record and the internal table containg IDOC data and importing an internal table consisting of control records for each communication IDOCS created.

4) Triggering via Change pointer

Change Pointer table is read and checked if changes were made to important fields , if so the outbound program will be triggered automatically , these have predefined interfaces
