    Lets Understand EDI , EDIFACT and ALE

    EDI >> Electronic Data Interchange EDI defines the paradigm of exchanging data electronically more than anything else

    It is easier to describe the commonly used EDI practices

    The collection of these common practices amounts to what is known today as EDI

    EDI can be thus described as an information sharing system

    utilizing an intermediate message store-and-forward entity and

    premeditated message syntax and interaction processes

    which are modeled by trading partners around standard templates

    EDI

    The Basic EDI structure is given below Each partner has their own internal software systems

    Special EDI adapters have to be implemented which will be able to interface with theinternal system as well as communicate with the value added network

    The particulars of the message syntax and interaction process are negotiated betweenpartners in advance

    Sometimes a dominant partner will impose its standards on smaller partners

    EDIFACT

    EDIFACT stands for EDIFor Administration, Commerce and Transportation

    It has been introduced by the UN center for the facilitation of administration,commerce and transportation (UN/CEFACT) in the mid 1980s

    Older European EDI standards such as TRADACOM, GENCOD, SEDAS andODETTE have all migrated to EDIFACT

    EDIFACT has furthermore become an international standard as ANSI hasstopped all work on X12 since 1997 and X12 systems are migrating to EDIFACT

    Message Type:A message typerepresents the application message being exchangedbetween R/3 systems and another R3/non-R3 external system. e.g.: MATMAS, INVOIC

    It is the representation of the data from a business perspective.

    IDOC Type:An IDOC typerepresents the structure of the data associated with amessage type. eg: MATMAS03, INVOIC02.

    It gives the actual hierarchy in which business data should be arranged.

    IDOC:An IDOCis an Instance of an IDOC Type, it is an object with the data of aparticular message type in it. In simpler terms, each idoc (represented by an idocnumber) contains the data sent by the Sender partner to the Receiver partner.

    Mass Processing

    Processing more than one IDOC can improve throughput:

    more than one IDOC is processed per Commit Work

    the function can be coded to add multiple entries to a table with one update command(array insert)

    Function module has to be coded in a way that it supports mass processing

    Pros:

    Easy to program

    Cons:

    Call Transaction has significant performance overhead

    Automatic Commit work, no data consistency

    Recommendation:

    Try to use function modules that update database directly

    If you want to use Call transaction, they have been ALE-enabled to guaranteedata concistency
