  • Tax with the help of idoc and EDI

    Dear gurus,
    how can we process tax data that is used between two systems through the help of IDOC and EdI? It would be great for ur kind support.

    Hi Amit,
         I do not understand how a non-sap system having an idoc adapte?
    Do you mean the non-sap system has the ability to understand the IDOC files?
    If yes, then your scenario is typically a IDOC-to File scenario.
    Read this:
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/e07dcaa0-a92b-2a10-3a96-b3d942bd1539
    If you do not intend to use XI in between, then you can just configure the outbound IDOCs in your SAP system and configure a file port in we21 transaction and create the partner profile in we20 transaction.

  • Comparison between split Adapter in Seeburger and EDI Separator

    Hello All,
    Currently we are designing EDI interfaces using B2B Add-On.
    I am trying to compare the split Adapter of Seeburger and EDI Separator of B2B Add-on.
    In Seeburger Splitter configuration:
    The additional split configuration helps to map the Sender ID, (EDIType,Transaction,Version) combination to split channel and sender agreement.
    I believe a List of Sender Id, Mappings (Standard, Transaction, Version) combinations can be added to the same Split channel and Sender Agreements.
    In B2B Add-On:
    The sender ids , EDI details are directly mentioned in the channel and it is bound to sender agreement.
    Does it reduce the flexibility in EDI Scenarios.Is that a correct point of view?
    Your inputs highly appreciated.
    Thanks.
    Regards,
    Sudharshan N A

    Dear Sudharshan,
    yes, I would say that this is a correct point/observation. When the Seeburger Adapters were introduced many years ago, one focus was put on the flexibility by keeping all functionality related to the "format conversion" (Classifier/Bic/Splitter) completely separated from the "data transmission" functionality directly in the channel.
    This way, the format conversion modules could be included in any adapter that was running on the AdapterEngine and not just to the See-Adapters.
    In a typical setup on client side, almost all inbound channels were using the "AUTO" functionality to detect all required parameters to select the right Split-Channel...so all channels had the same module-chains included (no matter if it was an AS2-Channel or a simple FILE/FTP-channel.
    This also allowed for easy reprocessing of any received file (via AS2, X400 , OFTP or else....) by just putting the file again to a file-channel with the same module-chain parameters.
    Kind Regards
    Stefan
    Btw... I am not very familiar with the B2B AddOn, but if you have additional questions regarding the Seeburger-EDI-Adapters, feel free to ask...

    It is the medium , how out put can be sent to customer.
    You can specify, for example, that the output is printed or that it is produced and sent by other means, such as fax, electronic mail, or electronic data interchange (EDI).
    If we want to send SAP Customer to SAP Customer we have to use - ALE

    Hi,
    ALE Process Steps:
    Outbound:
    Step 1.  Application document is created when transaction is saved.
             2.  Message control is invoked.
             3.  Messages are processed by system.
             4.  Messages are Edited (if desired).
             5.  Output (ALE /  EDI) is checked
             6.  Validate against Message control record from Partner Profile
             7.  Application Document is saved.
             8.  Entry NAST table is created for every selected output program
                  along with Medium & Timing.
             9.  Check for Process Immediately .
                     If (yes)
                       Determine Processing Program from TNAPR Table.
                     ELSE
                       Execute RSNASTED Program.
           10.  Read Partner Profile to determine Process Code.
           11.  Process Code points to the Function Module & Invoked.
           12.  IDoc is generated. 
           13.  Check for ALE Request.
                        if (Yes)
                            Perform Filters, Conversions, Version Changes etc.
                        Else.
                            IDoc is stored in DATABASE.
    INBOUND:
    Step 1.  EDI Subsystem creates an IDoc file from EDI Messages
            2.   Subsystem calls Functional Module                                 EDI_DATA_INCOMING from startRFC program.
             3.  Data in Control Record is validate against the Partner                       Profile.
            4. IDoc is generated in Database and syntax check is                      carried out.
            5. IDoc file is deleted once file read.
            6. Event PROCESSSTATE REACHED is triggered in Idoc Object Workflow. 
                       7.  Check for Process Immediately.
                   If NO
                     Execute RBDAPP01 Program
                   Else
                      Read Process Code from Partner Profile        
                           Process Code Points to  Function Module

  • IDOC and EDI

    Hi,
      Please send me some useful information on IDOC'S and EDI with relevance to SD module and comman errors with this documents.

    Standard SAP format for electronic data interchange between systems (Intermediate Document).
    Different message types (for example, delivery confirmations or purchase orders) normally represent the different specific formats, known as IDoc types. Multiple message types with related content can be assigned to one IDoc type
    Example:
    The IDoc type ORDERS01 transfers the logical message types ORDERS (purchase order) and ORDRSP (order confirmation).
    Among other areas, IDocs are used in both Electronic Data Interchange (EDI) and for data distribution in a system group (ALE
    Another
    The EDI interface is used to connect an EDI subsystem to the SAP system. EDI subsystems perform all EDI-related tasks such as Converting the data Handling messages or interchanges Communications Managing the partner profiles Monitoring processing. The EDI interface is based on IDoc technology. IDoc technology is independent of EDI standards. All data is exchanged via files between the SAP System and the EDI subsystem. The synchronous RFC (remote function call) is used to define the time of transfer of the files between both systems. Via the EDI interface, the following data can be exchanged:
    Outbound IDocs. IDocs are transferred from the SAP System to the EDI subsystem.
    Inbound IDocs. IDocs are transferred from the EDI subsystem to the SAP System.
    Status report. To inform the SAP System of the progress of processing of the outbound IDocs, the EDI subsystem transfers the status report to the SAP System.
    The object of the certification is the technical test of the interface between SAP System and EDI subsystem. The transfer of outbound IDocs, inbound IDocs and the status report are tested. The test is performed for the EDI standard UN/EDIFACT. As an example, the messages used are:
    Outgoing order (ORDERS)
    Incoming order (ORDERS)
    Outgoing order response (ORDRSP) and
    Incoming order response (ORDRSP).

  • What is the difference between ALE and EDI

    Hi,
    Can any one please explain what is the difference between ALE and EDI ?
    Thanks in advance.
    Ramana

    Hi Ramana
    ALE: used to trnasfer IDOC with in the R3distributed system.
    EDI: used to transfer IDOC from R3system to nonsap system
    IDOCS:
    IDOCS are intermediary documents which are like CARRIERS of the data
    IDOCs are safe to transfer data, but less volume of data. User is not allowed to access (modify) the data like PSA. IDOCs have 3 parts.
    1. Control Record - SOURCE & TARGET details,
    EDI
    EDI concept in SD: the EDI concept is intended to realize the sales and distribution process completely automatically with the help of electronical documents. These documents are sent from one customer to another, are processed mostly on the background and give a possibility to realize the sales process extremely efficiently.
    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.

  • SAP XI and EDI

    Hi all,
    I have some questions about SAP XI and EDI.
    We are planning to get the SAP XI to handle EDI message e.g. ANSI 850, but it looks like XI does not handle EDI out of the box. From what I read we still need to buy an EDI adaptor to handle the EDI-to-IDOC and IDOC-to-EDI processing. e.g. Seeburger adaptor.
    Actually I don't quite get this, isn't it XI contains a set of tools that allows us to do the mapping? Can we just use those tools to create EDI map without buying the seeburger adaptor? If we cannot create EDI map ourselves, then isn't it SAP XI is just an expensive message router??
    Any inputs are greatly appreciated. Thanks.

    XI has its own built-in message mapping tool (drag and drop GUI), upon which you can do "any-to-any" mapping. You can also do your mapping in ABAP, Java, or XSLT environments if you feel that the message (graphical) mapping tool doesnt enable you to do everything you want.
    So yes ... you can use XI's mapping functionality to map from iDoc to EDI format. However, this can be quite a complex exercise: you will need to setup the structure of the (target) EDI message/data type, and then carry out the mapping yourself - depending on the type of interface, this could be quite a complex exercise (typically EDI structures contain a very large number of fields).
    Once the iDoc has been mapped into the EDI format ... you will need to transmit (send) the EDI message to your (business) partner system, who is typically outside of your firewall (B2B). This means you need to communicate with them using a secure communication protocol (typically OFTP via VAN in EDI scenarios). And this is where the SeeBurger EDI adapters add value. They enable you to connect to VANs (Value Added Networks) using OFTP (or x.400), and also provide mappings for some EDI scenarios (which you can use).
    iWay also provide adapters for this purpose.

  • Whats the dfference between IDOC, ALE and EDI?

    whats the dfference between IDOC, ALE and EDI?

    Hi,
    1)EDI
    Electronic Data Interchange
    Cross-company exchange of electronic data (for example business documents) between domestic and international business partners who use a variety of hardware, software, and communication services. The data involved is formatted according to predefined standards. In addition to this, SAP ALE technology is available for data exchange within a company.
    Refer
    http://www.erpgenie.com/sapedi/index.htm
    2) ALE
    A means of creating and operating distributed applications.
    Application Link Enabling (ALE) guarantees a distributed, but integrated, R/3 installation. This involves business-controlled message exchange using consistent data across loosely linked SAP applications.
    Applications are integrated using synchronous and asynchronous communication - not by using a central database.
    ALE consists of the following layers:
    Application services
    Distribution services
    Communication services

    Check this link ALE and EDI
    http://www.onestopsap.com/interview-Question/edi/
    IDocs act as data containers in an ALE scenario. They are just a format of storing application data and then transferred using ALE. Take a look at this for further details on ALE.

  • Difference btw idoc ale and edi

    Hi all,
    I'm a beginner in abap, can anyone send me the concepts of ALE, IDOC and EDI and the difference btw all the three.
    Also do send some materials for the same.

    Hi,
    ALE (Application Linking and Enabling)
    Ale Technology is SAP’s technology to support distributed yet integrated processes across several SAP systems.
    Distributed Process:
    A distributed process is one in which part of a business process is carried out on one system and part on another. The two systems would exchange data with each other at appropriate points to stay synchronized.
    Need for Distributed Process:
    • Business in Different Geographical Locations.
    • Non availability of dedicated network.
    • Cultural and language differences in Geographical locations.
    • Running of Mission-critical Applications (Like Maintenance downtime etc.).
    • Separate up gradation of Modules.
    Distributed SAP SYSTEM – CHALLENGES
    • A system that understands the syntax and semantics of the data. It was important from the very beginning to base the distribution of data on business rules, not on database replication techniques.
    • Distributed systems that can maintain their autonomy while being integrated as one logical SAP system. The systems should be able to operate independently and support logical processing of transactions and data.
    • Distributed systems that can handle different data models. A local implementation should be able to customize the system to meet its local needs.
    • Receiving systems that can handle their own problems and not tie up the sending system.
    • Systems that maintain continued operation in spite of network failure. Changes made to either system should be synchronized after the network connection is restored.
    • A sound technology and methodology that can be used in all distribution scenarios.
    SAP Distributed environment:
    ALE allows for efficient and reliable communication between distributed processes across physically separate SAP systems.
    ALE is based on application to application integration using messaging architecture. A message defines data that is exchanged between two processes. IDocs are containers that hold data exchanged between the two systems.
    Benefits of ALE:
    • Integration with non-SAP systems: ALE architecture allows third party applications to integrate with SAP system.
    • Reliable Distribution: Once message type created and the receiver of the message is determined, ALE delivers the message to the recipient. If there is any network problem it will buffer the message and delivers the message once the network is restored. It also ensures that the message is not delivered twice.
    • Release Upgrade: Any of the distributed system can be upgraded to the new release of SAP without affecting the functionality. The ALE layer ensures backward compatibility of messages exchanged between systems.
    ALE Architecture:
    It consists of an Outbound process, an Inbound process, and an Exception – Handling process.
    Outbound Process:
    ALE Outbound Process in SAP sends data to one or more SAP Systems. It involves four steps.
    1. Identify the need of IDoc: This step starts upon creating a application document, can relate to a change to a master data object.
    2. Generate the Master IDoc: The document or master data to be sent is read from the database and formatted into an IDoc format. This IDoc is called as a Master IDoc.
    3. Generate the Communication IDoc: The ALE Service layer generates a separate IDoc from the Master IDoc for each recipient who is interested in the data. Separate IDocs are generated because each recipient might demand a different version or a subset of the Master IDoc. These recipient-specific IDocs are called Communication IDocs and are stored in the database.
    4. Deliver the Communication IDoc: The IDoc is delivered to the recipients using an asynchronous communication method. This allows the sending system to continue its processing without having to wait for the destination system to receiver or process the IDoc.
    Inbound Process:
    The inbound process receives an IDoc and creates a document in the system.
    1. Store the IDoc in the database: The IDoc is received from the sending system and stored in the database. Then the IDoc goes through a basic integrity check and syntax check.
    2. Invoke the Posting Module: The control information in the IDoc and configuration tables are read to determine the posting program. The IDoc is then transferred to its posting program.
    3. Create the Document: The posting program reads the IDoc data and then creates a document in the system. The results are logged in the IDoc.
    Over view of IDocs:
    IDoc is a container that is used to exchange data between any two processes. The document represented in an IDoc is independent of the complex structure SAP uses to store application data. This type of flexibility enables SAP to rearrange its internal structure without affecting the existing interface.
    IDoc interface represents an IDoc Type or IDoc data. IDoc Type represents IDoc’s definition and IDoc Data is an instance of the IDoc Type.
    IDoc Types:
    IDoc type structure can consist of several segments, and each segment can consist of several data fields. The IDoc structure defines the syntax of the data by specifying a list of permitted segments and arrangement of the segments. Segments define a set of fields and their format.
    An IDoc is an instance of an IDoc Type and consists of three types of records.
    i. One Control record: each IDoc has only one control record. The control record contains all the control information about an IDoc, including the IDoc number, the sender and recipient information, and information such as the message type it represents and IDoc type. The control record structure is same for all IDocs.
    ii. One or Many Data records: An IDoc can have multiple data records, as defined by the IDoc structure. Segments translate into data records, which store application data, such as purchase order header information and purchase order detail lines.
    iii. One or Many Status records: An IDoc can have multiple status records. Status record helps to determine whether an IDoc has any error.
    Message in IDoc Type:
    A Message represents a specific type of document transmitted between two partners.
    Outbound Process in IDocs:
    Outbound process used the following components to generate an IDoc. A customer model, and IDoc structure, selection programs, filter objects, conversion rules, a port definition, an RFC destination, a partner profile, service programs, and configuration tables.
    The Customer Model:
    A customer model is used to model a distribution scenario. In a customer model, you identify the systems involved in a distribution scenario and the message exchanged between the systems.
    Message control:
    Message control is a cross application technology used in pricing, account determination, material determination, and output determination. The output determination technique of Message control triggers the ALE for a business document. Message control separates the logic of generating IDocs from the application logic.
    Change Pointers:
    The change pointers technique is based on the change document technique, which tracks changes made to key documents in SAP, such as the material master, customer master and sales order.
    Changes made to a document are recorded in the change document header table CDHDR, and additional change pointers are written in the BDCP table for the changes relevant to ALE.
    IDoc Structure:
    A message is defined for data that is exchanged between two systems. The message type is based on one or more IDoc structures.
    Selection Program:
    Is typically implemented as function modules, are designed to extract application data and create a master IDoc. A selection program exists for each message type. A selection program’s design depends on the triggering mechanism used in the process.
    Filter Objects;
    Filter Objects remove unwanted data for each recipient of the data basing on the recipients requirement.
    Port Definition:
    A port is used in an outbound process to define the medium in which documents are transferred to the destination system. ALE used a Transactional RFC port, which transfers data in memory buffers.
    RFC Destination:
    The RFC destination is a logical name used to define the characteristics of a communication link to a remote system on which a function needs to be executed.
    Partner Profile:
    A partner profile specifies the components used in an outbound process(logical name of the remote SAP system, IDoc Type, message type, TRFC port), an IDoc’s packet size, the mode in which the process sends an IDoc (batch versus immediate), and the person to be notified in case of error.
    Service Programs and Configuration Tables:
    The outbound process, being asynchronous, is essentially a sequence of several processes that work together. SAP provides service programs and configuration tables to link these programs and provide customizing options for an outbound process.
    Process flow for Distributing Transactional Data:
    Transactional data is distributed using two techniques: with Message control and without message control.
    Process flow for Distributing Master Data:
    Master data between SAP systems is distributed using two techniques: Stand alone Programs and Change Pointers.
    Triggering the Outbound Process via Stand-Alone Programs:
    Stand-Alone programs are started explicitly by a user to transmit data from one SAP system to another. Standard Programs for several master data objects exist in SAP. Ex. The material master data can be transferred using the RBDSEMAT program or transaction BD10.
    The stand-alone programs provide a selection screen to specify the objects to be transferred and the receiving system. After the stand-alone program is executed, it calls the IDoc selection program with the specified parameters.
    Triggering the Outbound Process via Change Pointers:
    The change pointer technique is used to initiate the outbound process automatically when master data is created or changed.
    A standard program, RBDMIDOC, is scheduled to run on a periodic basis to evaluate the change pointers for a message type and start the ALE process for distributing the master data to the appropriate destination. The RBDMIDOC program reads the table TBDME to determine the IDoc selection program for a message type.
    Processing in the Application Layer:
    The customer distribution model is consulted to make sure that a receiver has been defined for the message to be transmitted. If not, processing ends. If at least one receiver exists, the IDoc selection program reads the master data object from the database and creates a master IDoc from it. The master IDoc is stored in memory. The program then calls the ALE service layer by using the function module MASTER_IDOC_DISTRIBUTE, passing the master IDoc and the receiver information.
    Processing in the ALE Interface Layer:
    Processing in the ALE Layer consists of the following steps:
    • Receiver Determination: The determination of the receiver is done through Customer Distribution Model.
    • IDoc Filtering: if an IDoc filter is specified in the distribution model for a receiver, values in the filter are compared against the values in the IDoc data records. If a data record does not meet the filter criteria, it is dropped.
    • Segment Filtering: For each sender and receiver combination, a set of segments that are not required can be filtered out.
    • Field conversion: Field values in data records are converted by using the conversion rules specified for the segment.
    • Version change for segments: Segments are version-controlled. A new version of a segment always contains fields from the preceding version and fields added for the new version. Release in IDoc type field of the partner profile to determine the version of the segment to be generated.
    • Version change for IDocs: IDocs are also version controlled. The version is determined from the Basic Type field of the partner profile.
    • Communication IDocs generated: The final IDoc generated for a receiver after all the conversions and filtering operations is the communication IDoc. One master IDoc can have multiple communication IDocs depending on the number of receivers identified and the filter operations performed. IDoc gets the status record with a status code of 01 (IDoc Created).
    • Syntax check performed: IDoc goes through a syntax check and data integrity validation. If errors found the IDoc get the status of 26 (error during syntax check of IDoc – Outbound). If no errors found the IDoc gets the status 30 (IDoc ready for dispatch – ALE Service).
    • IDoc dispatched to the communication Layer: In the ALE process, IDocs are dispatched using the asynchronous RFC method, which means that the sending system does not await for data to be received or processed on the destination system. After IDocs have been transferred to the communication layer, they get a status code 01 (Data Passed to Port OK).
    Processing in the Communication Layer:
    To dispatch an IDoc to a destination system, the system reads the port definition specified in the partner profile to determine the destination system, which is then used to read the RFC destination. The RFC destination contains communication settings to log o to the remote SAP system. The sending system calls the INBOUND_IDOC_PROCESS function module asynchronously on the destination system and passes the IDoc data via the memory buffers.
    Inbound Process in IDocs:
    An inbound process used IDoc structure, posting programs, filter objects, conversion rules, a partner profile, service programs, and configuration tables to post an application document from an IDoc.
    Posting Program:
    Posting programs, which are implemented as function modules, read data from an IDoc and create an application document from it. A posting program exists for each message. Each posting program is assigned a process code. A process code can point to a function module or a work flow. In the standard program process codes always point to a function module.
    Ex. The posting program for message type MATMAS is IDOC_INPUT_MATMAS which has a process code MATM.
    Workflow:
    A workflow represents a sequence of customized steps to be carried out for a process. The workflow management system is used to model the sequence, identify information required to carry out the steps and identify the person responsible for the dialog steps.
    Partner Profile;
    A partner profile specifies the components used in an inbound process (partner number, message type, and process code), the mode in which IDocs are processed (batch versus immediate), and the person to be notified in case of errors.
    Process flow for the Inbound process via a Function Module:
    In this process, IDocs are received from another system and passed to the posting function module directly.
    1. Processing in the communication Layer:
    The IDOC_INBOUND_ASYCHRONOUS program, triggered as a result of an RFC from the sending system, acts as the entry point for all inbound ALE processes. The IDoc to be processed is passed as an input parameter. Control is transferred to the ALE/EDI layer.
    2. Processing in the ALE/EDI Interface Layer:
    • Basic integrity check: A basic integrity check is performed on the control record.
    • Segment Filtering and conversion: Filtering out unwanted segments and carry out any required conversion of field values.
    • Creation of Application IDoc: The application IDoc is created and stored in the database and a syntax check is performed. If there are errors it gets status code of 60 (Error during Syntax check of IDoc – Inbound). At this point a tangible IDoc, which can be monitored via one of the monitoring transactions, is created and the IDoc gets status code 50 (IDoc Added).
    • IDoc Marked ready for Dispatch: IDoc gets the status code 64 (IDoc ready to be passed to application).
    • IDoc is passed to the posting program: The partner profile table is read. If the value of the Processing field is set to Process Immediately, the IDoc is passed to the posting program immediately using the program RBDAPP01.
    3. Processing in the Posting Module:
    The process code in the partner profile points to a posting module for the specific message in the IDoc. The posting program implemented as a function module either calls a standard SAP transaction by using the Call Transaction command for posting the document or invokes a direct input function module.
    The results of execution are passed back via the function module’s output parameters. If the posting is successful IDoc gets the status code 53 (Application Document Posted) or it gets status code 51 (Error: Application Document Not Posted).
    IDOC:
    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.
    SAP ALE & IDOC<<<<
    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)
    RFC:
    RFC (Remote Function Call) is similar to the general SAP fun module: except that in the attributes you click the radio button: RFC enabled;
    and you will be passing an Import parameter DESTINATION to it.
    Other code and usage will be similar to any fun module;
    Have a look at any fun module in SE37 to understand better about the different components of Fun modules;

    EDI:
    Electronic Data Interchange
    Cross-company exchange of electronic data (for example business documents) between domestic and international business partners who use a variety of hardware, software, and communication services. The data involved is formatted according to predefined standards. In addition to this, SAP ALE technology is available for data exchange within a company.

    EDI FLOW :
    Here is some thing which helps you and here the purchase order is taken as example too..
    Electronic Data Interchange, or EDI, is the electronic exchange of business data. Using a standard format, EDI provides a method of transmitting business data from one computer to another, without the need to re-key data. This electronic link can result in more effective business transactions. With EDI, paper documents such as invoices can be replaced with electronic transmissions, thus time is saved, and the potential for error is minimized. Data can be exchanged at any time. Related business expenses, such as postage, printing, phone calls, and handling, can also be significantly reduced. EDI can aid in the support of manufacturing efforts, such as Just-in-Time and Third Party Warehousing, and financial efforts, such as Electronic Payments.
    What parts of the business cycle can be supported by EDI?
    Any business documents that are currently exchanged using paper can be converted to an EDI. Standards. Standards include ANSI X12 and XML/EDI are primarily used in the United States, while EDIFACT is used in Europe and Asia.
    How does EDI get started?
    EDI gets started when one company contacts another expressing interest in trading business documents electronically using Electronic Data Interchange. The two companies must first determine each other's EDI capabilities. If you do not already know your EDI capabilities, we have prepared a questionnaire to help you determine them. If you are already EDI capable, we will coordinate with your technical staff to determine a testing plan. Upon completion of testing the EDI documents, the appropriate business personnel will set a production start date to begin the exchange of EDI business data. If you are not EDI capable, we recommend you first obtain a commitment from your upper management. Your company will need to allocate resources and capital for software, hardware, testing, possible programming, and training.
    What is the flow of EDI?
    The flow of EDI depends on the sophistication of your systems and your EDI software. If you have internal purchasing/order entry systems, you will need interface programs that can extract and insert data out of and into these systems. EDI programs that interface with your internal systems are preferred over software that requires re-keying of data. Embassy Software specializes in seemless interface between EDI and your back office systems. Using a purchase order as an example of a business document your customer would send that PO electronically (850) to you. It could be sent either through a VAN (Value Added Network) or through an FTP server. You would take that 850 and convert it either into and ODBC database, a flat file or XML document to be imported into your Order System with the use of EDI Software such as PassportXchange.. Using EDI communication software, which is part of the PassportXchange package you would pull down data at set intervals from the VAN or FTP. These documents are then processed through EDI translation software and output to our order entry system. Finally, an EDI document called a functional acknowledgment (997) is sent to your customer.
