Concept of IDOC's and ALE

Hi Friends,
I want to learn the concept of IDOC's and ALE.I want to understand the functionality that IDOC an d ALE has. May I have the guidance from anyone who  can guide me how to create IDOC's?? And also how this two terms are related to each other.
The Support will be definitely appreciated.:-)
Thanks in Advance....

hi,
OPEN DATASET
     Opens the specified file. If you do not use any additions, the file is opened for reading in binary mode. It returns SY-SUBRC = 0 if the file is opened successfully. Otherwise SY-SUBRC = 8.
Syntax
OPEN DATASET <dsn> [Additions].
Additions:
     1.  FOR INPUT     ( Default ) 2.  FOR OUTPUT  3.  FOR APPENDING
1. OPEN DATASET <dsn> FOR INPUT.
     This statement tries to open the field in 'read/update' mode (as long as the user has write authorization).If the user does not have write authorization, the system opens the file in 'read' mode. If this fails, an error occurs.
2. OPEN DATASET <dsn> FOR OUTPUT.
     This statement tries to open the file in 'write/update' mode as long as the user has read authorization. If the authorization is missing, the system opens the file in 'write' mode. If the file already exists, its existing content is deleted. If the file does not exist, the system creates it.
3. OPEN DATASET <dsn> FOR APPENDING.
     This statement tries to open the file in 'append' mode. If the file is already open, the system moves to the end of the file. When you open a file using FOR APPENDING, attempting to read the file sets SY-SUBRC to 4. The system display the end of the file.
CLOSE DATASET
          Closes the specified file.
Syntax
     CLOSE DATASET <dsn>.
DELETE DATASET
     Deletes the file specified file. If it deletes the file successfully it returns SY-SUBRC = 0. Otherwise returns SY-SUBRC = 4. The possible reasons for failing  are:
  The file does not exist.
  The file is a directory.
  The file is a program that is currently running.
TRANSFER statement
     Used to write a record into a file.
Syntax
     TRANSFER f TO dsn.
     Transfers the data object f to a sequential file whose name is specified in dsn. dsn can be a field or a literal. You must already have opened the file. . If the specified file is not already open, TRANSFER attempts to open the file FOR OUTPUT IN BINARY MODE. If this is not possible, a runtime error occurs.f can be a field, a string, or a structure.
Hope This Helps u,

  • What is IDOC and ALE?

    Hi anybody,
             Please tell me what is IDOC and ALE? What pupose using IDOC and ALE?
              Give me  Example sample code  of using IDOC and ALE.
    Thanks
    S.Muthu.

    Dear,
    Here is some facts which will be helpful to clear yr concepts for ALE/IDOCs.
    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.
    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.
    *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.
    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.
    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

  • IDOC and ALE Configuration with cross application with SD

    Hi Sap Gurus,
    Please send me some document on IDOC and ALE Configuration with cross application with SD.
    Please send me the material on my mail id [email protected]
    Regards
    shekhar

    Dear Shekhar,
    concerning 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.
    If MM-customer would like to purchase the goods then he creates the IDOC of type ORDERS and send it to SD-customer. On the SD-side the IDOC is processed via the function module IDOC_INPUT_ORDERS and creates the sales order. As confirmation the SD-side can send to MM-side the Order-Response IDOC (function IDOC_OUTPUT_ORDERS). The MM-customer can every thime send a change to the existiong order, then on SD side the ORDCHG IDOC will be processed. It can change the order like in VA02. The creation of the invoice can be made via IDOC of message type INVOIC (function IDOC_OUTPUT_INVOIC).
    So, the process can be realized completely automatically between SD and MM partners with the help of IDOCs: ORDERS, ORDCHG, ORDRSP, INVOIC.
    That's all concerning the SD-EDI.
    Additional processes in SD, where EDI are used:
    1) application of delivery schedules to the scheduling agreement: IDOC of type DELINS
    2) creation of a delivery order to the scheduling agreement: IDOC of type DELORD
    3) creation of external agent service delivery to scheduling agreement: IDOC of type EDLNOT
    4) creation of credit advice / credit memo in the frames of self-billing: IDOCs of type GSVERF, SBWAP and for external invoice creation SBINV.
    It is all processes which are realized in the SD module via EDI.
    I hope this info helps.
    Kind regards,

  • Differences between rfc and ale/idoc.

    hi ..
           will u please send the differences between rfc and ale/idoc's.

    Hi,
    Please reward with points if helpful................
    ALE is SAP proprietary technology that enables data communications between two or more SAP R/3 systems and/or R/3 and external systems. There are three layers in ALE system: application services, distribution services, and communication services.
    For communication services, ALE performs a Remote Function Call (RFC) using the port definition and RFC destination specified by the customer model. RFC is used to communicate between applications of different systems in the SAP environment includes connections between SAP systems as well as between SAP systems and non-SAP systems. Remote Function Call (RFC) is the standard SAP interface for communication between SAP systems. The RFC calls a function to be executed in a remote system.
    Means of creating and operating distributed applications.
    The purpose of Application Line Enabling is to guarantee a distributed, but integrated, R/3 installation. This involves business-controlled message exchange with consistent data across loosely linked SAP applications.
    Application integration is achieved not via a central database, but via synchronous and asynchronous communication.
    Application Link Enabling comprises the following three layers:
    application services
    distribution services
    communication services
    Two Development Models
         Distribution using BAPIs
         Distribution using Message type
    The programming model "Distribution using message types" contains the definitions of message types and IDoc types and the ABAP code for processing inbound and outbound IDocs.
    Defining message types and IDoc types:
    If you want to create message type enhancements for master data distribution, you also have to create a new message type for each enhancement.
    The ALE interface does not allow you to create different segment data for different IDoc types for the same message type.
    Writing ABAP code:
             Outbound Processing

    Hi,
    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.
    How to create idoc?

    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 )
    Creating a Segment
    Go to transaction code WE31
    Enter the name for your segment type and click on the Create icon
    Type the short text
    Enter the variable names and data elements
    Save it and go back
    Go to Edit -> Set Release
    Follow steps to create more number of segments
    Create IDOC Type
    Go to transaction code WE30
    Enter the Object Name, select Basic type and click Create icon
    Select the create new option and enter a description for your basic IDOC type and press enter
    Select the IDOC Name and click Create icon
    The system prompts us to enter a segment type and its attributes
    Choose the appropriate values and press Enter
    The system transfers the name of the segment type to the IDOC editor.
    Follow these steps to add more number of segments to Parent or as Parent-child relation
    Save it and go back
    Go to Edit -> Set release
    Create Message Type
    Go to transaction code WE81
    Change the details from Display mode to Change mode
    After selection, the system will give this message u201CThe table is cross-client (see Help for further info)u201D. Press Enter
    Click New Entries to create new Message Type
    Fill details
    Save it and go back
    Assign Message Type to IDoc Type
    Go to transaction code WE82
    Change the details from Display mode to Change mode
    After selection, the system will give this message u201CThe table is cross-client (see Help for further info)u201D. Press Enter.
    Click New Entries to create new Message Type.

    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)

    RBDMOIND - Status Conversion with Successful tRFC Execution
    RBDMANIN - Start error handling for non-posted IDocs
    RBDSTATE - Send Audit Confirmations
    FOr testing you can use WE19.
    There are two filtering in IDoc.
    Segment Filtering:
    Segment filtering can be achieved using T/Code BD56. Here you can suppress a whole segment irrespective of data inside it . You have to give Message Type / Sender Prrtner / Receiver Partner.
    Data Filtering:
    Data filtering can be done in dustribution model (BD64) where you can restrict whole IDOCS or partials IDOCS to be send based on data in fields inside IDOC depending on whether the segment in which you filter is at the highest level or at a lower level. For example in MATMAS if you put a filter of E1MARCM for a particular plant , only data for this plant will go and other plants will be ignored.

  • What are IDOC and ALE?

    We are getting a new system that will be interfacing to SAP via IDOC and or ALE
    I am required to quickly reply back as far as what will be required from a BASIS side if they will interface using IDOCS and ALEs
    Thank YOU and kind Regards!
    M.

    Hi Maria,
    Application Link Enabling (ALE) is a mechanism or u can say that it's a tool for the exchange of business data between loosely-coupled R/3 applications built by customers of SAP, the enterprise resource management program. ALE provides SAP customers with a program distribution model and technology that enables them to interconnect programs across various platforms and systems.That means that ALE can integrate business processes between R/3 Systems and non-R/3 systems as well as between R/3 Systems.
    There are three layers in the ALE system:
    a)     application services,
    b)     distribution services, and
    c)     communication services.
    The vehicle for data transfer is called an IDoc (intermediate document), which is a container for the application data to be transmitted.
    After a user performs an SAP transaction, one or more IDocs are generated in the sending database and passed to the ALE communication layer. The communication layer performs a Remote Function Call (RFC), using the port definition and RFC destination specified by the customer model. The IDoc is transmitted to the receiver, which may be an R/3, R/2, or some external system. If the data is distributed from a master system, the same transaction performed by the sender will be performed by the receiving system, using the information contained in the IDoc.
    Changes made to fields in master data tables can be set to trigger distribution of the changes to slave systems, so that multiple database servers can update the same information simultaneously. IDocs carry information directly between SAP systems. In order to communicate with a non-SAP system, an IDoc is first transmitted to an intermediary system that translates the data to a format that will be understood by the receiver. Return data also passes through the translating system, where it is again encapsulated into an IDoc.
    Now comes to ur 2nd query basis guys duties over IDOCS & ALE
    a)Creating the RFC
    b)monitoring different layers over ALE
    c)Archiving IDOCS (when required)
    d)use the Idoc display tool(we02)
    e)use the Idoc Search tool (we09)
    f)use the Status Monitor Tool(bd87)
    g)Troubleshooting the Inbound Idocsu2026.

  • Provide ALE and IDOC Faqs and all Transactions

    Dear Experts,
    I am new to ALE & IDOC.
    Please provide ALE & IDOCs FAQs and all Transactions?
    Thanks in advance.

    <b>FAQS</b>
    A L E
    Q: Our IDOC remains in status 51 ( not posted) while testing ALE setup by passing DEBMAS02 Idocs. The message 'Field KNA1-BRSCH is not an input field'. This is the Industry key. What are we missing?
    A: Go to IMG - menu path IMG->LogisticsGeneral-> Logistics Basic Data: Business partners->Customers-> Control->Define Account groups and field selection for customer.
    Select sold-to or ship-to. Select General Data. Select control and double click. Industry key is found here. Change the option to 'Optional Entry'.
    Check OSS 5599. You may have to update view V_T078D also.
    E D I / IDOC
    Q:1 We created an EDI Vendor and created all required output conditions. However no IDOC is generated when PO is printed. Why?
    A: Go to Header->output for the PO. The output type shall be '6'. The status shall be '1'. If the status is '0' check the timing. If the status is '2' , go to 'GOTO->Processing Log' and the explanation for non-generation of IDOC can be seen.
    Q: How can we create / upload IDOC's from legacy system to SAP?
    A: Third party tool Mercator may be used to convert Legacy files to Idoc format. Mercator provides an IDOC tree import facility, SAP provides the export facility. You can transfer the Idoc layouts from SAP to Mercator automatically and then map.
    Q: We want to receive an outbound EDI 855 IDOC only if E2EDP20 -scheduling confirmation segment is present. Else get an "error" status preventing triggering the EDI subsystem.
    A: User exit logic has to be added in function IDOC_INPUT_ORDRSP.
    Set up a test flag and set it off when the IDOC header is read.
    Turn the flag ON when the EDP20 segment is read.
    Interrogate this flag when the next segment after EDP20 in the same IDOC comes in. If it is on ,you have an EDP20 coming in.
    Issue an error status 51 with suitable message for whichever condition you don't want the IDOC to be processed, This will stop the IDOC from posting.
    Q: Where ever PO is sent to the vendor via EDI, we want an acknowledgement of the PO by vendor. Which fields are updated and what should be my procedure?
    A: Execute Program: IDOC_INPUT_ORDRSP
    Process code: ORDR
    Message type: ORDRSP
    IDOC: ORDERS01
    The confirmation process allows the supplier to return an acknowledgment. Only Dates and quantities can be changed The information is stored in the PO and can be viewed via Item->Confirmation->Overview. The PO can be flagged as 'confirmation required' so that Pos without acknowledgement receipt can be monitored. Control keys and tolerances (days and quantities) have to be customized.
    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.

  • How to Use IDOC and ALE in SAP?

    Hi anybody,
                     I want Use Idoc and ALE in sap ABAP. What is inbound and outbout process of IDOC?
    Please give me sample code for Idoc . and Sample code for ALE.
    anybody Please tell me.
    Thanks
    Regards,
    S.Muthu.

    hi,
    Follow the link for step by step ALE/IDOC tutorials.
    http://www.sapmaterial.com/idoc_sample.html
    http://www.****************/Tutorials/ALE/ALEMainPage.htm
    An IDoc is not a process.
    The term IDoc stands for intermediate document. It is simply a data container used to exchange information between any two processes that can understand the syntax and semantics of the data. An IDoc is created as a result of executing an outbound ALE or EDI process. In an inbound ALE or EDI process, an IDoc serves as input to create an application document.
    IDocs are stored in the database.
    In the SAP system, they are stored in database tables. Several utilities are available to display the information contained in an IDoc and present it in different ways. For details, refer to Chapter 11, "Monitoring the Interface."
    Every IDoc has a unique number.
    When an IDoc is generated in the system, a unique number is assigned to it. This number is unique within a client.
    IDocs are independent of the sending and receiving systems. They can be used for SAP-to-SAP and SAP to non-SAP process communication as long as the participating processes can understand the syntax and semantics of the data.
    IDocs are based on EDI standards, ANSI ASC X12 and EDIFACT, but are closer to the EDIFACT standards. The size and format of data elements in an IDoc type are derived from these standards wherever applicable. For example, if a material number is represented by 20 characters in an EDIFACT message, the corresponding data element in the IDoc is also 20 characters. If there is a conflict in data size between standards, the one with greater length is adopted. This approach ensures compatibility with most standards.
    IDocs are independent of the direction of data exchange. An inbound and an outbound process can use an IDoc. For example, the ORDERS01 IDoc is used by the Purchasing module to send a purchase order, and is also used by the Sales and Distribution module to accept a sales order. Using this technique avoids creating redundant IDoc types for the same information.
    IDocs can be viewed in a text editor and do not contain any binary data. Data is stored in character format. When transferred to the operating system, an IDoc is stored in a file in text format and can be viewed using a regular text editor. However, the contents make sense only if you understand the structure and format of the data in that IDoc. In the Appendix, "FAQs, User Exits, and Miscellaneous Resources," you will find an example of an IDoc file.
    Hope this helps, Do reward.

  • I-DOC and ALE

    Hi, What is meant by I-DOC and ALE, How are the related? How they are involved in SAP Projects? please explain with one simple example?

    Hi Yadav,
    The ALE (Application Link Enabling) concept available in R/3 (Release 3.0) supports the development of applications across different SAP systems. It incorporates the exchange of business information across these systems whilst ensuring consistency and integrity of the data. This functionality is achieved with the use of Idocs (intermediate Document) as opposed to the use of a centralised database.
    Please refer this link,[Difference between EDI and IDOC|http://www.sap-img.com/basis/difference-between-edi-and-idoc.htm]

  • IDOC: Error in ALE Service

    Hi All,
    I have created a new outbound idoc type ZSLSRPT and assigned it to a partner profile with type LI in we20. I tried running my customized program for idoc outbound and the status shows<b> Error in ALE Service, Entry in outbound table not found</b>.
    Am I missing something with the partner definition? Do I need to configure the vendor output type in NACE? Please help.
    Thanks,
    Kenny

    Hi Kenny,
    Have you setup the distribution model (BD64) for the corresponding message type?

  • Idoc Acknowledgements and Idoc Packaging

    All,
    I am implementing a requirement wherein we need to post 2 different types of Idoc's from our BPM.  The Business requirements is such that until the Idoc 1 is not processed by the R3 system, the Idoc 2 should not be posted from XI as there is dependency in the data.
    This can be addressed using  Application Acknowledgements. The solution to this is to use the send step in my BPM with application acknowlegement. Until the application acknowledgement is not received for the first send step , the next send  step will not be processed and so things will / should work fine.
    The problem comes in the fact that the Idoc's being sent out of XI use Idoc Packaging, ie., the First Send Step uses Idoc Packaging to post multiple Idoc's to the target system.  A question that arises due to Idoc packaging and Idoc ack's are,
    <i><b>How will the Idoc Ack's be sent back to XI?</b></i>
    I have read through the online help and it states that every ALE AUDIT Idoc can contain the status of maximum 500 Idoc's. Now, in  my  case , when using my Idoc packaging, if the number of Idoc's are greater than 500, how will the Application Acknowledgement for the Idoc's work?  Will I still get a single acknowlegement in my BPM or will I get multiple acknowledgements? Will Send Step with Application acknowledgement still hold good?
    Any ideas, thoughts / experiences on using idoc ack's with idoc packaging?
    Regards
    Bhavesh

    If I undestatood correcty you have 2 send step, the first send a message containing multiple IDoc (IDoc Packaging). In this first send step you set the application Acknowledgements.
    I think that this is not managed from the BPM, bacause the acknowledgements will come someone positive and someone negative, and so when the first send step will be completed ?
    I think that the solution must to be changed a little bit, or removing the IDoc Packaging, or removing the wait of Acknowledgements.
    Also take in mind that if you use a BPM with many possible correlation (Acknowledgements) you will have bed performances.
    Regards,
    Sandro
