官方介绍：

What is a IDOC?

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. IDoc is not a process.

-         IDocs are stored in the database.

-         In the SAP system, IDocs are stored in database tables.

-         IDocs are independent of the sending and receiving systems.

-         IDocs are independent of the direction of data exchange.

An IDoc Type is SAP's format for data being moved between applications. Essentially, SAP has defined what a sales order, financial statement, invoice, etc will look like electronically. This includes how fields are grouped together (segments), the order and hierarchy of these groupings, and the format of each individual field.

If you're familiar with EDI at all, then an IDoc will look very familiar to you. Nearly everything you're used to is there: from segment name to allowable codes to min/max occurs.

It is important to note that an IDoc Type is really just a structure defined on the system and given a name (i.e., ORDERS04). An actual IDoc, however, consists of data, which fits within the defined structure of the IDoc Type. This IDoc is identified by a number rather than by a type.

Creation of IDOCs

Transaction code: WE 30

Steps of Defining Segment

Creating Segment : Tcode - WE31

Creating Message Type : Tcode - we81

Assigning Message type to Idoc type: Tcode - we82

Process

The two processes for IDoc are Outbound Process and Inbound Process.

Outbound Process

When the data is sent out from the system, the process is called Outbound Process and the IDoc is known as Outbound IDoc.

Inbound Process

When the data is coming in, the process is called Inbound Process and the IDoc is known as Inbound IDoc.

Outbound Process (Sending System) Steps :

1) Goto Tcode SALE:

Creating the logical system

Click on Sending & Receiving Systems à Select Logical Systems--Here Define the Logical Systems à Click on Execute Button

Go for New Entries

1)  System Name : LOG1:Description: Sending System

2)  System Name : LOG2:Description: Receiving System

Press Enter & Save it will ask for Request if you want new request create new request or press continue for transferring the objects.

Assigning Client to the Logical System:

Select Assign Client to Logical Systems -

Client                   : Sending System

Logical System    : LOG1

and also

Client   : Receiving System

Logical System    : LOG2

Save this Data.

Step 2) For RFC Creation:

Goto Tcode SM59 and  Select R/3 Connects

Click on create Button

RFC Destination Name should be same as partner's logical system name and case sensitive to create the ports automatically while generating the partner profiles

Give the information for required fields:

RFC Destination    : LOG2

Connection type    : 3

Target Host            : sappdc.wipro.com

System No              : 00

Client                      : 210

User                        : Login user name

Password                :

Save this & Test it and Remote Login

Step 3) Goto Tcode BD64:

Click on the change button>Click on the create model view

Short Text: model view

Technical Name: LMOD

Save this & press ok

Select just created model view

Name: "LMOD"

Goto add message type

Model Name  : LMOD

Sender           : LOG1

Receiver         : LOG2

Message type: ZAZHARMESS

Save and press Enter.

4) Goto Tcode BD82:

Give Model View   : LMOD

Partner system     : LOG2

Execute this by pressing F8

It will gives you sending system port No:  A00000000089 (Like)

5) Goto Tcode BD64:

Select the model view

Goto >Edit >model view > Distribute

Press ok & Press Enter.

Run your Zprogram

REPORT  ZIDOC1                             .

DATA: Begin of imara occurs 0,

matnr like mara-matnr,

mtart like mara-mtart,

end of imara.

DATA: wamas_con LIKE edidc,

imas_data LIKE edidd OCCURS 0 WITH HEADER LINE,

icom_con LIKE edidc OCCURS 0 WITH HEADER LINE.

PARAMETERS: e_matnr LIKE mara-matnr,

e_msgtyp LIKE edidc-mestyp,

e_rcvprn LIKE edidc-rcvprn.

* retrive app. data from DB

SELECT matnr mtart FROM mara INTO TABLE imara WHERE

matnr = e_matnr.

*Master idoc control record

wamas_con-rcvprt = 'LS'.

wamas_con-rcvprn = e_rcvprn.

wamas_con-idoctp = 'ZAZHARIDOC'.

wamas_con-mestyp = e_msgtyp.

* master idoc data records

LOOP AT imara.

imas_data-segnam = 'ZAZHARSEG'.

move imara to imas_data-sdata .

APPEND imas_data.

ENDLOOP.

CALL FUNCTION 'MASTER_IDOC_DISTRIBUTE'

EXPORTING

master_idoc_control = wamas_con

TABLES

communication_idoc_control = icom_con

master_idoc_data = imas_data

COMMIT WORK.

6) Verifying Transfer of IDOCs Tcode - we05

ALE/IDOC Status Codes (outbound):

01> IDoc Added

30 > IDoc ready for dispatch

29 >Error in ALE service Layer

12 >Dispatch ok

03 > Data passed to port ok.

Inbound Process (Receiving System) Steps:

Do the same step as you did in sending system

>  Creating IDoc

>   Defining the Segment

>   Creating Message Type

>   Assigning the Message Type

>   Defining the Logical System

>   Assigning the Logical System

>   Creating the Distribution Model

1) Goto Tcode - we57:

Assign function module to IDoc type

Module: Function module

Basic type:

Message type:

Direction: 2 (inbound)

2) Creating Inbound process code - we42

3) Verifying Idoc List Tcode - we05

4) ALE/IDOC Status Codes (Inbound):

50 > IDoc Added

51 >Application Document not posted

64 >IDoc ready to be transferred to application

62 >IDoc passed to application

53 >Application Document posted
