Hi ,

EDI is nothing but Electronic data interchange. SAP will support EDI through Intermediate documents (IDOCS).

EDI is also called paperless exchange.

Reduced Data entry errors

Reduced processing time

Availabilty of data in electonic form

Reduced paperwork

Reduced Cost

Reduced inventories and better planning

Standard means of communications

Better business process

EDI has two process

1. Outbound process

2. Inbound process

OP:

1.Application document is created.

2.IDOC is generated

3.IDoc is transferred from SAP to Operating system layer

4.Idoc is converted into EDI standards

5.Edi document is transmitted to the business partner

6.The Edi Subsystem report status to SAP

IP:

1.EDI transmission received

2.EDI document is converted into an IDOC

3.IDOC is transferred to the SAP layer

4.The application document is created

IDOC:

IDOC is a container that can be used to exchange data between any two process.

Each iDoc is assigned a unique number for tracking and future reference.

iDoc Consist of several segments,and segments contain several fields.

iDoc contains the following three type of records...

PORT:

Port is used in the outbound process to determine the name of the EDI subsystem program,the directory path where the idoc file will be created at the operating system level,the idoc file names and the rfc desinations.

RFC Destination:

Used to define the characteristics of communication links to a remote system on which a functions needs to be executed.

Partner Profile:

Partner profile specified the various componets used in an outbound process ( Partner number,IDoc type,message type,Port,Process code),the mode in which it communicates with the subsystem(batch or immediate) and the person to be notified in case of errors.
