ALE Idoc is method to migrate data between two SAP systems.whereas EDI used to transfer data

between one SAP and other non-SAP systems and vice versa.

IDoc (for intermediate document) is a standard data structure for data migration

between two SAP application programs.it carries Business Information.

Business Data is of three types-

1. Control Data - i.e. configuration data (client, company code etc.)

2. Master Data - i.e. Application level data (Material/vendor master etc.)

3. Transactional Data - i.e. also Application level data (Like invoice, billing etc)

For control data IDocs are created once, and after being transferred it can not be changed,

whereas for transactional and master data many IDOCs can be created.

Structure of IDOC-

Message Type- Can contains several segments.

Segment Type- Actual contents of the data contained into the SEGMENT.Segments are the

section of data.Segments containns the fields, it means ields are the

basic building block of any segment.segments are identified by the Sequence no. of the segment i.e. IDOCSYN.

EDIDD,EDIDC,EDID4 are the tables for IDOC data.

Imp. Terms -

Logical System - Logical system is an appropriate name to identify the sender and receiver.it should be

uniquely binded with a particular client.

CDM (Customer distribution model) - Is responsible for finding out the axact recepient for the IDOC.

Partner Profile - Recipient system should know what type of message it is going to receive from which system,for

this partner profile has to be created,every information related to PORT, RFC, LS, IDOC Type

should be maintained in Partner Profile.

RFC Destination - it will be the other SAP system.

Imp. Tcodes-

WE31 - Creating Segment

WE30 - Creating IDOC Type

WE81 - Creating Message Type

WE82 - Assigning Message type to IDOC

BD64 - Creating CDM

WE20 - Creating Partner Profile

BD82 - Generating Partner Profile Automatically

WE21 - Assign Port to RFC Destination

BD54/SALE - Creating logical System and assign LS to appropriate client.

SM59 - Creating RFC Destination

WE21 - Creating Port and assigning port to RFC destination.

Steps -

1. Create the Logical System.

2. Assign LS to Client.

3. Create RFC Destination.

4. Create PORT.

5. Bind the PORT with RFC dest. to create communication channel.

6. Create Partner Profile.

7. Create CDM.

8. Assign partner profile to CDM.

9. distributing the CDM.

To Create Message type-

10. Create Segment. (WE31)

11. Create IDOC.(WE30)

12. create Message type (WE81)

13. Assign Message type to Idoc Type.

14. Assign the IDOC type to partner profile.
