ALE IDOC object development

Hi All,
I am developing one object using ALE IDOC. But i have little knowledge of ALE IDOC.
The requirement is to pass data from from corporate HCM side to SAP BW side if there
is corresponding field in the SAP BW side. i know i have to use ALE ,IDOC for this. i am planning
to proceed as below (this help i got from SDN site only).
1) Creating a Function Module.
2) Using t-code BD51 to define the ALE attributes of the func module so that it can be assigned to process
    code latter.
3) Execute WE 57 to assign func module to idoc type and message type.
4) Execute WE 42  to define the process code and assign func module to the process code.
5) Create/ Modify the partner profile and include the new process code.
Please tell me how can i use these steps in my object development. Also i dont have any idea of "process code". Can any one of u help me in solving this.
Thanks,
Rupesh

what is the trigger point for data transfer ? that decides the exact process.

    Bdc to Bapi
    The steps to be followed are :
    1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).
    [for VA01 use BAPI_SALESORDER_CREATEFROMDAT2]
    2. Create a Z program and call the BAPi (same as a Funtion module call).
    2. Now, if you see this BAPi, it has
    -> Importing structures.
    eg: SALESDOCUMENT: this will take the Sales order header data as input.
    -> Tables parameters:
    eg: ORDER_ITEM_IN: this will take the line item data as input.
    Note :
    Only specify fields that should be changed
    Select these fields by entering an X in the checkboxes
    Enter a U in the UPDATEFLAG field
    Always specify key fields when changing the data, including in the checkboxes
    The configuration is an exception here. If this needs to be changed, you need to complete it again fully.
    Maintain quantities and dates in the schedule line data
    Possible UPDATEFLAGS:
    U = change
    D = delete
    I = add
    Example
    1. Delete the whole order
    2. Delete order items
    3. Change the order
    4. Change the configuration
    Notes
    1. Minimum entry:
    You must enter the order number in the SALESDOCUMENT structure.
    You must always enter key fields for changes.
    You must always specify the update indicator in the ORDER_HEADER_INX.
    2. Commit control:
    The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.
    For further details... refer to the Function Module documentation for the BAPi.
    Bapi to VB(Visual Basic)
    Long back I had used the following flow structure to acheive the same.
    Report -> SM59 RFC destination -> COM4ABAP -> VB.exe
    my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.
    You need to have com4abap.exe
    If com4abap is installed you will find it in sapgui installatin directory , C:\Program Files\SAPpc\sapgui\RFCSDK\com4abap.
    else refer OSS note 419822 for installation of com4abap
    after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.
    for setting up com4abap and rfc destination please refer to the documentation for com4abap.
    Invoke NEW DCOM session
    call function 'BEGIN_COM_SESSION'
    exporting
    service_dest = service_dest "(this will be a RFC destination created in SM59)
    importing
    worker_dest = worker_dest
    exceptions
    connect_to_dcom_service_failed = 1
    connect_to_dcom_worker_failed = 2
    others = 3.
    call function 'create_com_instance' destination worker_dest

  • Urgent: Application Object Type for ALE IDoc

    Hi All,
    I am struggling with ALE IDoc, I just wanted to know that is it mandatory to create Application Object Type when i have created my own message type, Idoc type, segment type and Function Module. I am Getting an error while excuting transaction we42( Maintaining Process code)
    Error: Application Object Type is not planned.
    Please Help with this.  i don't have any requirement of filtering or serialisation, so still do i need to create these application objects.
    Useful ans will be rewarded.
    Thanx

    Hi,
    Yes u need to have the assignment of Object type as ur extending the IDOC.
    Check the steps below:
    TCode- BD95.
    Create ALE object type  “Z...”  with table name “EKKO” and Field name “-BSART”
    Step2:
    Tcode- BD59 – “Assignment of Object type to Message”
    Give the message type “ORDERS”.
    Assign the object type “Z........” to segment type “E1EDK01’ with field “BSART”.

  • Objects in ale/idocs, bapi

    1)can any one give me any good object in ale /idocs and BAPI and explain them (senario where that is used and why and how  .
    i will give you maximun reward points if  i can understand them .

    Hi,
    IDOC Programming
    There are two processes in IDOC processing one is INBOUND PROCESS( IDOC coming to the system and its handling at various stages)  and the other is OUTBOUND PROCESS( IDOC is send to other system  . Separate ABAP programs are written for these 2 processes and different configuration settings are required for each one .Depending upon the trigeering mechanism different programming approaches are used.OUTBOUND PROGRAMS handle the IDOC creation and INBOUND PROGRAMS handle the inbound IDOC and the data trasfer from the IDOC to the database tables.
    NEED FOR ABAP PROGRAMMING arises if
    1)New IDOC was created
       Depending upon the triggering mechanism i.e change pointer,message control
       etc the programming technique changes and the type of process.
    2)Existing IDOC was extended
       User Exits are used to populate data in new segments added and to read them 
       back.
    3)To enhance an exsiting process.
       User Exits are used . 
    Basic structure of an OUTBOUND PROGRAM
    The basic structure of all outbound programs is same. The CONTROL
    record which is of TYPE EDIDC has to be filled. It contains important fields like
    IDOCTP      IDOC type
    MESTYP    Message Type
    RCVPRN    Recieving Partner (Destination)
    RCVPRT    Partner Type (it is LS i.e Logical System)
    The DATA RECORD internal table which is of TYPE EDIDD has to be filled
    in the same order as there are segments in the IDOC definition.
    It has 2 important fields which are to be filled ,these are
    SEGNAM  Name of the segment
    SEGDATA Data in the segment and can be upto 1000 bytes.This field
                    is corresponds to each data segment in the IDOC.
    e.g.
    DATA INT_EDIDD LIKE EDIDD OCCURS 0 WITH HEADER LINE.
    DATA W_SEGDATA LIKE zsegment "custom segment zsegment
           INT_EDIDD-SEGNAM = 'ZSEGMENT'
           W_SEGDATA-field1 = value    "taken from some table
           W_SEGDATA-field2 = value    "taken from some table
           INT_EDIDD-SEGDATA = W_SEGDATA
           APPEND INT_EDIDD
    This will fill the data record corresponding to the segment ZSEGMENT . For all
    segments the sam steps will be repeated until all the data corresponding to all the
    segments in the idoc is filled in the internal table of type EDIDD.
          There is only one control record and can be multile data records in the idoc
    structure.
    Which data is to be extracted from the tables to be filled in EDIDD type internal table is determined in standalone programs from the objects which are specified in the selection screen and from the object key passed to the function module in case of message control and is taken from BDCP table in case of change pointers using function modules "CHANGE_POINTERS_READ"
          In case of stand alone programs and function modules based on change pointers method the function module "MASTER_IDOC_DISTRIBUTE" is used to send the IDOC to ALE layer for distribution ,in case of message control it is handled automatically by the RSNASTED program invoked by the message control.                     
    OUTBOUND PROCESS AND OUTBOUND PROGRAM
    Outbound programs are used in outbound process to genearte IDOCs . There
    purpose is to extract the data from the tables and to fill the IDOC data records
    and the control record in the IDOC and pass ito the ALE layer for distribution to the recieving system .
    Depending upon the triggering mechanism (how and when the outbound program will be started different techniques and interface is used for outbound program.
    1)Message control
    Application like PO(purchase order) creation use this technique , where the output type is linked to the application(Message control is a configurable cross application component which can be set in IMG .Such programs are created in the form of function modules and linked to the output type which is linked to the apllication.These have predefined interfaces.
    In outbound programs(function module) that use message control the key of the
    application document is passed to the function module whcig will read the data from the table depending upon the key passed(NAST structure) and fill the IDOC segemnts with the application data.The control record is also passed to the function module but is not fully filled, the rmaining fields are filled and the control is passed back to the calling program which is RSNASTED and is invoked by the
    message control to process ALE and EDI output types and this program on recieving the IDOC data will create the physical IDOC in the system.
    The parameteers passed to the function module are
    IMPORTING PARAMETERS
    OBJECT LIKE NAST
      It contains documents key.
    CONTROL_RECORD_IN  LIKE EDIDC
      It contains the partailly filled control record
    EXPORETING PARAMETER
    OBJECT_TYPE
    CONTROL_RECORD_OUT LIKE EDIDC
    TABLES
    INT_EDID LIKE EDIDD
    The internal table used to fill the data records in the same order as they exists in 
    the IDOC.
    The important parameters that should be filled in the custom function module are
    CONTROL_RECORD_OUT and  INT_EDIDD .The OBJK field of the structue NAST contains the key of the apllication document.
    2)Stand alone programs
      Generally used for Master Data transfer and as such depending upon the requirement can have different interfaces.The programs have a selection screen which has select options to select the objects, and parameters for specifying the recipient Logical System and the Message Type.
    Data is selected based on the specified objects from the tables . and control record of type EDIDC is created and filled with important values like DIRECTION ,IDOCTP,RCVPRT,RCVPRN and MESTYP .
    Data is filled in an internal table of TYPE EDIDD according to segment definitions
    and in same order and the function module MASTER_IDOC_DISTRIBUTE is called passing the control record and the internal table containg IDOC data and importing an internal table consisting of control records for each communication IDOCS created.
    3)Change pointer
    Change Pointer table is read and checked if changes were made to important fields , if so the outbound program will be triggered automatically , these have predefined interfaces

  • Data transfer using ALE/IDOC into XML.

    Dear All,
    I have to transfer FI document data (FB01) from the sap system ,convert it into XML and dump it in 1 of the file servers.I want to do this using ALE/IDOC.Is it possible to do the same and how.Similarly i want to do the same for Vendor and Customer master i.e sending the data in XML format.
    Kindly Suggest how do i go about doin the same..Its very urgent.Please help.
    Thanks & Regards,
    Lailu Philip.

    In continuation:
    Example Purchasing & Selling scenario
    We will develop a custom IDoc to carry the billing number from the Service Receiver’s system to the Service Provider’s system. We will populate the IDoc in a user exit on the sending side and we will process the transaction on the receiving side using a custom function module and a BDC transaction call.
    No rule conversion, segment filtering or version conversion will be implemented in the model as described in Figure 1.
    Requirements
    • Working ALE environment - See ALE Basis Configuration Guide;
    • ALE scenario design together with the business requirement;
    • Development access; and
    • ALE configuration access.
    NOTES:
    1. All IMG references to transactions are located in the transaction SALE which is the ALE portion of the IMG
    2. This is one way of developing a scenario where no message control exists. If message control exist (EG. On purchase orders) then NAST can be used to call an outbound function module that would create the required IDocs.
    3. Extensive knowledge of IDocs and ALE basis configuration is required in order to understand this guide.
    2. OUTBOUND PROCESSING
    2.1. Create IDoc type (WE30) Client independent
    The IDoc type refers to the IDoc structure that you will require for your development. In our case the IDoc type is called ZINVRV01. This IDoc type will have 1 segment called Z1INVRV with 2 fields, LIFNR & XBLNR, in this segment. If you require many segments or nested segments then they are also created using the same procedure.
    We will create the IDoc of the following structure:
    ZINVRV01
    Purchasing and Selling - Invoice receipt reversal
    Z1INVRV P&S - Segment 1
    Segment fields
    LIFNR Vendor account number
    XBLNR Reference document number
    Figure 3: IDoc type ZINVRV01
    To create the IDoc type, follow these next few steps:
    • Enter transaction WE30 (ALE -> Extensions -> IDoc types -> Maintain IDoc type)
    • Type in ZINVRV01 and click on Basic IDoc type, click the Create icon
    • Click on Create new (we are creating an IDoc from scratch but you may want to copy another IDoc if it is similar to your requirements) and enter a description, and press enter
    • Click on ZINVRV01 and then on the Create icon
    • Enter Z1INVRV as the segment type (must start with Z1), check mandatory if the segment must exist (in this case check it), enter 1 in minimum number and 1 as maximum number. (Make the maximum number 9999999999 if there are going to be many of these segments in each IDoc. IE. When line items are passed via IDocs), click on Segment editor
    • Enter a description for your segment type and create
    • Enter a description for your segment, enter each field required in your IDoc, in our case type LIFNR across for Field name, DE structure and DE documentation, repeat for XBLNR and press enter to validate.
    • Save and generate, press back
    • To release the segment choose Goto, Release from the menu
    • Check the box on the line of your new segment
    • Save, back and enter
    • Your IDoc type structure should be displayed with your new segment
    • Save and back
    • To release the IDoc type choose Extras, Release type from the menu and Yes
    Your IDoc is now ready for use. If you need to add fields or segments to your IDoc type, you will need to cancel the release of the IDoc type as well as the segment release using a similar procedure followed above (except now you uncheck the release box for the segment and you choose cancel release for the IDoc type).
    2.2. Create message type (WE81) Client independent
    To create a new message type, follow these next few steps:
    • Enter transaction WE81 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> Create logical message type)
    • Choose Create logical message type by double clicking on it
    • Click on change icon to enter change mode
    • Click on New entries to add a new type
    • Enter the required message type, in our case it is ZINVRV and an appropriate description
    • Save and exit.
    Your message type has now been created. The next step will be to link it to the IDoc.
    2.2.1. Link message to IDoc type (WE82 & BD69) Client independent
    To link the message type to the IDoc type follow these next few steps:
    • Enter transaction WE82 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> EDI: Message Types and Assignment to IDoc Types)
    • Click on change icon to enter change mode
    • Click on New entries to create the link
    • Enter the message type ZINVRV and the BasicIDoc type as ZINVRV01
    • Save and exit
    • Enter transaction BD69 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> Assign message type to IDoc for ALE)
    • Click on change icon to enter change mode
    • Click on New entries to create the link
    • Enter the message type ZINVRV and the BasicIDoc type as ZINVRV01
    • Save and exit
    Your IDoc is now linked to your message type. We still need to link object types and add the message to the model before we can use the message.
    2.2.2. Maintain object type for message type (BD59) Client independent
    The ALE objects are used to create links between IDocs and applications objects, to control the serialisation, to filter messages in the customer model and to use listings.
    For our own message type and IDoc you must maintain object types for the links.
    If you want to check the serialisation for the message type, then you must maintain object types for the serialisation. If no serialisation object has been maintained for a given message type, then the serialisation will not be checked for this message type.
    To add an object type to our message type, follow these next few steps:
    • Enter transaction BD59 (ALE -> Extensions -> ALE object maintenance -> Maintain object types)
    • Type in your message type ZINVRV and press enter
    • Click on New entries
    • Enter your object type, LIFNR (We need to use the vendor as a filter object), the segment name where LIFNR resides, Z1INVRV, a number 1 for the sequence followed by the actual field name LIFNR
    • Save and exit.
    You have now created an object that we’ll use as a filter object in the customer model to direct the flow of messages to the various logical systems based on the vendors in the filter of the message type ZINVRV.
    We now need to add our new message type to the distribution model.
    2.3. Configuring the Distribution Model
    This task is performed on your ALE reference client.
    2.3.1. Manual Configuration (BD64) Client dependent
    To manually configure the customer distribution model, read the ALE configuration procedure, and follow these steps:
    • Perform the Maintain customer distribution model directly function. (ALE -> Distribution customer model -> Maintain customer distribution model directly)
    • Specify the customer model you want to maintain and the logical system that is to be the sender of the messages OR create a new model. (Create model ALE with logical system ALELS1C400)
    • Choose the receiving systems to which the sending system must forward message type ZINVRV to.
    • For each receiving logical system allocate the message type necessary for communication to the receiving systems as per ALE configuration procedure.
    • Create filter objects (in our case LIFNR as the object type with the associated vendor number, 0000018001 with leading zeros, in the object area) for the message types.
    • Save the entries.
    NOTES:
    You cannot maintain a message type between the same sender and receiver in more than one customer distribution model.
    Only the owner is authorised to modify the model.
    To change the owner of a model, choose the 'Maintain ownership of customer distribution model' function. Make sure that all changes will be distributed to all systems that know the corresponding model. To do so, you can use the correction and transport system.
    To transport the customer distribution model you should use the Distribute customer model function of the IMG as described below.
    2.3.2. Distribute customer model (BD71) Client dependent
    After the customer model has been created centrally, it must be distributed to the other remote systems. This entails first of all setting up the communication for the distributed systems and then sending the model.
    2.3.2.1. Distribute Model (BD71) Client dependent
    This task is performed on your ALE reference client. To distribute the customer distribution model, read the ALE configuration procedure and follow these steps:
    • Make the settings for the communication with the other decentral systems, you have not set them yet.
    • Define the RFC destination for R/3 connections whose names correspond to the name of the corresponding logical system.
    • Create the output partner profile.
    • Distribute the customer model
    • Specify the name of the customer model.
    • You must specify the target system to which you want to distribute the customer model.
    • You must repeat this function for every distributed logical system.
    2.3.2.2. Maintain sending system partner profile (WE20) Client dependent
    With this function, you define the partner profiles for all outbound and inbound messages on the basis of the customer distribution model.
    After you have defined and distributed the customer model, you will have to maintain the partner profiles locally. To do this read the ALE configuration procedure.
    • Enter the output mode (background, immediately) and the package size for outbound processing.
    Requirements
    • The customer model must be maintained.
    • RFC destinations must be maintained.
    • The customer model must be distributed.
    • To ensure that the appropriate persons in charge are informed if a processing error occurs, you must make settings in: Error processing Maintain organisational units.
    2.4. Populate & distribute IDoc using ABAP
    An IDoc consists of a control record with structure edidc and one or more data records with structure edidd. The control record contains the sender and recipient of the IDoc, as well as information on the type of message.
    To be able to pass an IDoc to the ALE layer, you must set up a field string with structure edidc and an internal table with structure edidd. They are used to call function module master_idoc_distribute, which performs the save to the database and triggers the dispatch if necessary.
    2.4.1. Example code
    The code displayed below does the following:
    • populates our IDoc segment Z1INVR with the 2 fields XBLNR and LIFNR, populates the segment name and appends this to an internal table used to store the IDoc data;
    • populates the control record info with the message type and IDoc type; and
    • calls the MASTER_IDOC_DISTRIBUTE function module which distributes the IDoc as configured in the customer distribution model.

    3. INBOUND PROCESSING
    3.1. Create Function Module
    This function module is called when a message type, of type ZINVRV, comes into the receiving system. This needs to be configured and is dealt with later in this section. The function module is passed the IDoc as a parameter.
    Example parameters
    Import parameters Reference field Opt Y/N
    INPUT_METHOD BDWFAP_PAR-INPUTMETHD N
    MASS_PROCESSING BDWFAP_PAR-MASS_PROC N
    Export Parameters Reference field Opt Y/N

    APPLICATION_VARIABLE BDWFAP_PAR-APPL_VAR N

    Table Parameters Reference field Optional Y/N
    IDOC_CONTRL EDIDC

    IDOC_STATUS BDIDOCSTAT
    RETURN_VARIABLES BDWFRETVAR
    SERIALIZATION_INFO BDI_SER
    Exceptions
    WRONG_FUNCTION_CALLED
    Example code
    The code displayed below does the following:
    • populates a BDC table with the IDoc info;
    • calls the transaction via a BDC call; and
    • updates the IDoc status according to the BDC error status.
    EXTRACT FROM: Z_IDOC_INPUT_ZINVRV
    Declaration of local variables
    DATA: C_SEGNAM(10) TYPE C VALUE 'Z1INVRV'.
    *-Loop through the IDOCs
    LOOP AT IDOC_CONTRL.
    *---Loop through the data for the IDOC
    LOOP AT IDOC_DATA WHERE DOCNUM = IDOC_CONTRL-DOCNUM.
    CASE IDOC_DATA-SEGNAM.
    WHEN C_SEGNAM.
    Here we get the info from the idoc table
    IT_Z1INVRV = IDOC_DATA-SDATA.
    ENDCASE.
    PERFORM REV_INV.
    ENDLOOP.
    PERFORM UPDATE_IDOC_STATUS.
    ENDLOOP.
    FORM REV_INV "Reverse invoice form
    Local variables & constants
    DATA: C_TCODE LIKE BKPF-TCODE VALUE 'VF11'. "BDC transaction code
    Now we can build the bdc table to call the reversal transaction start of screen 109
    CLEAR BDC_TAB.
    BDC_TAB-PROGRAM = 'SAPMV60A'.
    BDC_TAB-DYNPRO = '109'.

    CLEAR BDC_TAB.
    BDC_TAB-FNAM = 'BDC_OKCODE'.
    BDC_TAB-FVAL = 'SICH'.
    APPEND BDC_TAB.
    Now we can call transaction 'VF11' with the populated bdc table. The transaction is called inside the idoc-contrl loop, so a transaction will be called for every idoc (journal). the transaction is called in no-display mode ('N') because this code runs in background as it is called by ale. The update is specified to be synchronous ('S') because we have to wait for the result to update the idoc status correctly.
    CALL TRANSACTION C_TCODE USING BDC_TAB MODE 'N' UPDATE 'S'.
    Store the return code for use in another form (status update)
    RETURN_CODE = SY-SUBRC.
    Here we check the return code, if there was an error, we put the transaction in a bdc session for the user to review and correct.

    Figure 5: Inbound processing example code
    3.1.1. Debugging inbound FM
    Use transaction WE19 to test inbound function module in debugging mode. Also use WE05 to view the IDocs and their statuses.
    3.2. Maintain ALE attributes
    The inbound function module needs to be linked to the message type and the message type needs to be linked to the appropriate inbound process code at the partner profile level before the scenario is enabled. These steps are described below in detail.
    3.2.1. Link Message Type to Function Module (WE57) Client independent
    To link a message (ZINVRV) type to a function module (Z_IDOC_INPUT_ZINVRV) follow these steps:
    • Enter transaction WE57 (ALE -> Extensions -> Inbound -> Allocate function module to logical message)
    • Select an entry (EG. IDOC_INPUT_ORDERS) and copy
    • Type in module name Z_IDOC_INPUT_ZINVRV
    • Type in basic IDoc type as ZINVRV01
    • Type in message type as ZINVRV
    • Type object type as IDOCINVOIC (Invoice document) - Used for workflow
    • Direction should be set to 2 for inbound
    • Enter and save
    3.2.2. Define FM settings (BD51) Client independent
    • Enter transaction BD51 (ALE -> Extensions -> Inbound -> Define settings for input modules)
    • Click on New entries
    • Type in the name of the new function module Z_IDOC_INPUT_ZINVRV
    • Enter 0 for mass processing in the output column
    • Save and Exit
    3.2.3. Maintain process codes (WE42) Client dependent
    A process code needs to be maintained on each client. It then needs to be linked to the message via the partner profiles on each client. This allows the various clients to use a unique function module for the same message type.
    To maintain the process code follow these steps:
    • Log on to the appropriate receiving system client
    • Execute WE42 (ALE -> Extensions -> Inbound -> Maintaining process codes inbound)
    • Choose Inbound with ALE service
    • Choose Processing with function module
    • Click on Processing with function module and choose create icon
    • Click on New Entries
    • Type in process code ZINR and give it a description and save
    • Now you are asked to Please maintain codes added in ALE entry methods, enter and choose Z_IDOC_INPUT_FIRVSL and copy it. You should choose a FM similar to your one.
    • Enter your process code ZINR
    • Enter your function module Z_IDOC_INPUT_ZINVRV
    NOTE: The next 6 steps are used in workflow error handling.
    • Enter IDPKFIDCMT in object type
    • Enter MASSINPUTFINISHED in End event
    • Enter IDOCINVOIC in IDoc object type
    • Enter INPUTERROROCCURREDFI in IDoc start event
    • Enter INPUTFINISHEDFI in IDoc End event
    • Enter IDOCINVOIC in Application object type
    You will need to determine the task associated with object IDOCINVOIC, and then assign the appropriate position to it. This position will then receive the application error messages via workflow.
    To set up the workflow area please consult the Workflow config guide.
    3.3. Create inbound partner profile
    For each message type you need to maintain the inbound partner profiles.
    3.3.1. Maintain receiving system partner profile (WE20) Client dependent
    To maintain inbound partner profiles read the document ALE configuration procedure:
    • Add the message type ZINVRV with process code ZINR.
    • Enter the output mode (background, immediately) for inbound processing and NO message code.
    • Enter the position S and choose the ALE administrator 50000085. This position will then receive all the technical ALE errors via workflow.
    3.4. Test
    Once the inbound function module has been debugged the scenario should be ready to test in its entirety. If problems occur, read through the relevant areas of this document to check your configuration or code.
    Hope this will help you,
    If you  want me to explain more, you can give me your email id.
    Reward with points incase you are satisfied.

  • Ale-idoc  steps

    Hi All,
    Can any one please give me the step by step ale-idoc toturial.about the steps to send data from one client to other.
    Regards,
    bunty

    Hi,
    <b>
      It gives, entire idoc documentation.
    http://help.sap.com/saphelp_nw04/helpdata/en/3b/beb13b00ae793be10000000a11402f/frameset.htm
    To develop a new custom ALE scenario, comprises 5 steps:
    1. Design and develop the custom IDoc with it’s segments and a new message type
    2. Configure the ALE environment with the new IDoc and message type (customer model, partner profiles and linking IDoc to message type)
    3. Develop the outbound process which does the following:
    • Populates the custom IDoc with control info and functional data
    • Sends the IDoc to the ALE layer for distribution
    • Updates status and handles errors
    4. Configure the ALE inbound side (partner profiles with inbound process code)
    5. Develop the inbound process which does the following:
    • Reads the IDoc into a BDC table; selects other data that is required
    • Runs transaction using call transaction or BDC session
    • Updates status and handles errors
    Below is a pictorial representation of the flow of a complete ALE scenario from the sending system to the receiving system.
    Figure 1: ALE Scenario model
    1.1. ALE Example
    For the purposes of this example we will develop a small ALE scenario. This scenario is described below.
    “The receiver of an internal service must be able to reverse (cancel) the invoice receipt which will then cancel the applicable billing document automatically on the service provider’s system.”
    Figure 2: Example Purchasing & Selling scenario
    We will develop a custom IDoc to carry the billing number from the Service Receiver’s system to the Service Provider’s system. We will populate the IDoc in a user exit on the sending side and we will process the transaction on the receiving side using a custom function module and a BDC transaction call.
    No rule conversion, segment filtering or version conversion will be implemented in the model as described in Figure 1.
    Requirements
    • Working ALE environment - See ALE Basis Configuration Guide;
    • ALE scenario design together with the business requirement;
    • Development access; and
    • ALE configuration access.
    NOTES:
    1. All IMG references to transactions are located in the transaction SALE which is the ALE portion of the IMG
    2. This is one way of developing a scenario where no message control exists. If message control exist (EG. On purchase orders) then NAST can be used to call an outbound function module that would create the required IDocs.
    3. Extensive knowledge of IDocs and ALE basis configuration is required in order to understand this guide.
    2. OUTBOUND PROCESSING
    2.1. Create IDoc type (WE30) Client independent
    The IDoc type refers to the IDoc structure that you will require for your development. In our case the IDoc type is called ZINVRV01. This IDoc type will have 1 segment called Z1INVRV with 2 fields, LIFNR & XBLNR, in this segment. If you require many segments or nested segments then they are also created using the same procedure.
    We will create the IDoc of the following structure:
    ZINVRV01
    Purchasing and Selling - Invoice receipt reversal
    Z1INVRV P&S - Segment 1
    Segment fields
    LIFNR Vendor account number
    XBLNR Reference document number
    Figure 3: IDoc type ZINVRV01
    To create the IDoc type, follow these next few steps:
    • Enter transaction WE30 (ALE -> Extensions -> IDoc types -> Maintain IDoc type)
    • Type in ZINVRV01 and click on Basic IDoc type, click the Create icon
    • Click on Create new (we are creating an IDoc from scratch but you may want to copy another IDoc if it is similar to your requirements) and enter a description, and press enter
    • Click on ZINVRV01 and then on the Create icon
    • Enter Z1INVRV as the segment type (must start with Z1), check mandatory if the segment must exist (in this case check it), enter 1 in minimum number and 1 as maximum number. (Make the maximum number 9999999999 if there are going to be many of these segments in each IDoc. IE. When line items are passed via IDocs), click on Segment editor
    • Enter a description for your segment type and create
    • Enter a description for your segment, enter each field required in your IDoc, in our case type LIFNR across for Field name, DE structure and DE documentation, repeat for XBLNR and press enter to validate.
    • Save and generate, press back
    • To release the segment choose Goto, Release from the menu
    • Check the box on the line of your new segment
    • Save, back and enter
    • Your IDoc type structure should be displayed with your new segment
    • Save and back
    • To release the IDoc type choose Extras, Release type from the menu and Yes
    Your IDoc is now ready for use. If you need to add fields or segments to your IDoc type, you will need to cancel the release of the IDoc type as well as the segment release using a similar procedure followed above (except now you uncheck the release box for the segment and you choose cancel release for the IDoc type).
    2.2. Create message type (WE81) Client independent
    To create a new message type, follow these next few steps:
    • Enter transaction WE81 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> Create logical message type)
    • Choose Create logical message type by double clicking on it
    • Click on change icon to enter change mode
    • Click on New entries to add a new type
    • Enter the required message type, in our case it is ZINVRV and an appropriate description
    • Save and exit.
    Your message type has now been created. The next step will be to link it to the IDoc.
    2.2.1. Link message to IDoc type (WE82 & BD69) Client independent
    To link the message type to the IDoc type follow these next few steps:
    • Enter transaction WE82 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> EDI: Message Types and Assignment to IDoc Types)
    • Click on change icon to enter change mode
    • Click on New entries to create the link
    • Enter the message type ZINVRV and the BasicIDoc type as ZINVRV01
    • Save and exit
    • Enter transaction BD69 (ALE -> Extensions -> IDoc types -> Maintain message type for intermed. Structure -> Assign message type to IDoc for ALE)
    • Click on change icon to enter change mode
    • Click on New entries to create the link
    • Enter the message type ZINVRV and the BasicIDoc type as ZINVRV01
    • Save and exit
    Your IDoc is now linked to your message type. We still need to link object types and add the message to the model before we can use the message.
    2.2.2. Maintain object type for message type (BD59) Client independent
    The ALE objects are used to create links between IDocs and applications objects, to control the serialisation, to filter messages in the customer model and to use listings.
    For our own message type and IDoc you must maintain object types for the links.
    If you want to check the serialisation for the message type, then you must maintain object types for the serialisation. If no serialisation object has been maintained for a given message type, then the serialisation will not be checked for this message type.
    To add an object type to our message type, follow these next few steps:
    • Enter transaction BD59 (ALE -> Extensions -> ALE object maintenance -> Maintain object types)
    • Type in your message type ZINVRV and press enter
    • Click on New entries
    • Enter your object type, LIFNR (We need to use the vendor as a filter object), the segment name where LIFNR resides, Z1INVRV, a number 1 for the sequence followed by the actual field name LIFNR
    • Save and exit.
    You have now created an object that we’ll use as a filter object in the customer model to direct the flow of messages to the various logical systems based on the vendors in the filter of the message type ZINVRV.
    We now need to add our new message type to the distribution model.
    2.3. Configuring the Distribution Model
    This task is performed on your ALE reference client.
    2.3.1. Manual Configuration (BD64) Client dependent
    To manually configure the customer distribution model, read the ALE configuration procedure, and follow these steps:
    • Perform the Maintain customer distribution model directly function. (ALE -> Distribution customer model -> Maintain customer distribution model directly)
    • Specify the customer model you want to maintain and the logical system that is to be the sender of the messages OR create a new model. (Create model ALE with logical system ALELS1C400)
    • Choose the receiving systems to which the sending system must forward message type ZINVRV to.
    • For each receiving logical system allocate the message type necessary for communication to the receiving systems as per ALE configuration procedure.
    • Create filter objects (in our case LIFNR as the object type with the associated vendor number, 0000018001 with leading zeros, in the object area) for the message types.
    • Save the entries.
    NOTES:
    You cannot maintain a message type between the same sender and receiver in more than one customer distribution model.
    Only the owner is authorised to modify the model.
    To change the owner of a model, choose the 'Maintain ownership of customer distribution model' function. Make sure that all changes will be distributed to all systems that know the corresponding model. To do so, you can use the correction and transport system.
    To transport the customer distribution model you should use the Distribute customer model function of the IMG as described below.
    2.3.2. Distribute customer model (BD71) Client dependent
    After the customer model has been created centrally, it must be distributed to the other remote systems. This entails first of all setting up the communication for the distributed systems and then sending the model.
    2.3.2.1. Distribute Model (BD71) Client dependent
    This task is performed on your ALE reference client. To distribute the customer distribution model, read the ALE configuration procedure and follow these steps:
    • Make the settings for the communication with the other decentral systems, you have not set them yet.
    • Define the RFC destination for R/3 connections whose names correspond to the name of the corresponding logical system.
    • Create the output partner profile.
    • Distribute the customer model
    • Specify the name of the customer model.
    • You must specify the target system to which you want to distribute the customer model.
    • You must repeat this function for every distributed logical system.
    2.3.2.2. Maintain sending system partner profile (WE20) Client dependent
    With this function, you define the partner profiles for all outbound and inbound messages on the basis of the customer distribution model.
    After you have defined and distributed the customer model, you will have to maintain the partner profiles locally. To do this read the ALE configuration procedure.
    • Enter the output mode (background, immediately) and the package size for outbound processing.
    Requirements
    • The customer model must be maintained.
    • RFC destinations must be maintained.
    • The customer model must be distributed.
    • To ensure that the appropriate persons in charge are informed if a processing error occurs, you must make settings in: Error processing Maintain organisational units.
    2.4. Populate & distribute IDoc using ABAP
    An IDoc consists of a control record with structure edidc and one or more data records with structure edidd. The control record contains the sender and recipient of the IDoc, as well as information on the type of message.
    To be able to pass an IDoc to the ALE layer, you must set up a field string with structure edidc and an internal table with structure edidd. They are used to call function module master_idoc_distribute, which performs the save to the database and triggers the dispatch if necessary.
    2.4.1. Example code
    The code displayed below does the following:
    • populates our IDoc segment Z1INVR with the 2 fields XBLNR and LIFNR, populates the segment name and appends this to an internal table used to store the IDoc data;
    • populates the control record info with the message type and IDoc type; and
    • calls the MASTER_IDOC_DISTRIBUTE function module which distributes the IDoc as configured in the customer distribution model.

    3. INBOUND PROCESSING
    3.1. Create Function Module
    This function module is called when a message type, of type ZINVRV, comes into the receiving system. This needs to be configured and is dealt with later in this section. The function module is passed the IDoc as a parameter.
    Example parameters
    Import parameters Reference field Opt Y/N
    INPUT_METHOD BDWFAP_PAR-INPUTMETHD N

    • calls the transaction via a BDC call; and
    • updates the IDoc status according to the BDC error status.

    Figure 5: Inbound processing example code
    3.1.1. Debugging inbound FM
    Use transaction WE19 to test inbound function module in debugging mode. Also use WE05 to view the IDocs and their statuses.
    3.2. Maintain ALE attributes
    The inbound function module needs to be linked to the message type and the message type needs to be linked to the appropriate inbound process code at the partner profile level before the scenario is enabled. These steps are described below in detail.
    3.2.1. Link Message Type to Function Module (WE57) Client independent
    To link a message (ZINVRV) type to a function module (Z_IDOC_INPUT_ZINVRV) follow these steps:
    • Enter transaction WE57 (ALE -> Extensions -> Inbound -> Allocate function module to logical message)
    • Select an entry (EG. IDOC_INPUT_ORDERS) and copy
    • Type in module name Z_IDOC_INPUT_ZINVRV
    • Type in basic IDoc type as ZINVRV01
    • Type in message type as ZINVRV
    • Type object type as IDOCINVOIC (Invoice document) - Used for workflow
    • Direction should be set to 2 for inbound
    • Enter and save
    3.2.2. Define FM settings (BD51) Client independent
    • Enter transaction BD51 (ALE -> Extensions -> Inbound -> Define settings for input modules)
    • Click on New entries
    • Type in the name of the new function module Z_IDOC_INPUT_ZINVRV
    • Enter 0 for mass processing in the output column
    • Save and Exit
    3.2.3. Maintain process codes (WE42) Client dependent
    A process code needs to be maintained on each client. It then needs to be linked to the message via the partner profiles on each client. This allows the various clients to use a unique function module for the same message type.
    To maintain the process code follow these steps:
    • Log on to the appropriate receiving system client
    • Execute WE42 (ALE -> Extensions -> Inbound -> Maintaining process codes inbound)
    • Choose Inbound with ALE service
    • Choose Processing with function module
    • Click on Processing with function module and choose create icon
    • Click on New Entries
    • Type in process code ZINR and give it a description and save
    • Now you are asked to Please maintain codes added in ALE entry methods, enter and choose Z_IDOC_INPUT_FIRVSL and copy it. You should choose a FM similar to your one.
    • Enter your process code ZINR
    • Enter your function module Z_IDOC_INPUT_ZINVRV
    NOTE: The next 6 steps are used in workflow error handling.
    • Enter IDPKFIDCMT in object type
    • Enter MASSINPUTFINISHED in End event
    • Enter IDOCINVOIC in IDoc object type
    • Enter INPUTERROROCCURREDFI in IDoc start event
    • Enter INPUTFINISHEDFI in IDoc End event
    • Enter IDOCINVOIC in Application object type
    You will need to determine the task associated with object IDOCINVOIC, and then assign the appropriate position to it. This position will then receive the application error messages via workflow.
    To set up the workflow area please consult the Workflow config guide.
    3.3. Create inbound partner profile
    For each message type you need to maintain the inbound partner profiles.
    3.3.1. Maintain receiving system partner profile (WE20) Client dependent
    To maintain inbound partner profiles read the document ALE configuration procedure:
    • Add the message type ZINVRV with process code ZINR.
    • Enter the output mode (background, immediately) for inbound processing and NO message code.
    • Enter the position S and choose the ALE administrator 50000085. This position will then receive all the technical ALE errors via workflow.
    3.4. Test
    Once the inbound function module has been debugged the scenario should be ready to test in its entirety. If problems occur, read through the relevant areas of this document to check your configuration or code.

                                                                                    What is IDOC
    IDocs are SAP’s file format to exchange data with a foreign system. IDocs is the acronym for Intermediate Document. This indicates a set of (electronic) information, which builds a logical entity. An IDoc is e.g. all the data of a single customer in your customer master data file. Or the Idoc is all the data of a single invoice.
    • IDocs are an ASCII file format to exchange data between computers; the format is chosen arbitrarily
    • IDocs are similar to segmented files; they are not a description language like ANSI X.12, EDIFACT or XML
    • The IDoc contents are processed by function modules, which can be assigned in customizing
    Process Steps for IDOC Programming
    The following steps are required for inbound and outbound IDOC Programming.
    Interpreting An IDoc Segment Info
    All IDoc data records are exchanged in a fixed format, regardless of the segment type. The segment’s true structure is stored in R/3’s repository as a DDIC structure of the same name.
    Go to transaction code WE31. Enter the name of the Segment, which is to be created (fig 2.1).
    E.g. Create the segment ZEMPMASTSEG
    Fig 2.1 WE31- IDOC Segment main screen.
    Fig 2.2 WE31 IDOC Segment definition screen.
    In the above screen user can enter the fields, which are necessary for the segment. Once all the necessary fields will be populated then Save the transaction. After Saving release the version of the Segment by selecting the version and through menu Edit -> Set release.
    Same way create one or more segment.
    Fig 2.3 WE31 – IDOC Segment definition screen for another segment (ZEMPMASTHEADERSEG).
    IDoc Type – The Structure of the IDoc File
    The IDoc type is the name of the data structure used to describe the file format of a specific IDoc.
    An IDoc is a segmented data file. It has typically several segments. The segments are usually structured into fields, however different segments use different fields.
    The IDoc type is defined with transaction WE30, the respective segments are defined with transaction WE31 as per the point 2
    Go to transaction code WE30. Enter the IDOC Type name.
    Fig 3.1 WE30 – IDOC Type main screen.
    Add the segments to the IDOC Type as per the requirement.
    For e.g. in the fig 3.2 it shown that IDOC Type is having only one segment ZEMPMASTHEADERSEG, which is having one child segment ZEMPMASTSEG
    Fig 3.2 WE30 – IDOC Type segment screen
    For each segment developer (double click on the segment) can set the minimum, maximum number of segment in a sequence.
    Fig 3.3 fig 3.4
    Defining the Message Type
    The message type defines the context under which an IDoc is transferred to its destination. It allows using the same IDoc file format to use for several different applications.
    The message type together with the IDoc type determines the processing function.
    The message type defined using transaction code WE81.
    fig 4.1 WE81 – Message Types
    Define Valid Combination Of Message and IDoc Types
    The valid combinations of message type and IDoc type are stored in table EDIMSG, using transaction WE82.
    The declaration of valid combinations is done to allow validation, if the system can handle a certain combination.
    Fig 5.1 WE82 – Message Type Assignment
    Process Step for Inbound IDOC Programming
    Characteristics of Inbound function module
    Before assigning the function module to Inbound process code, its characteristics must be set with the transaction BD51. This step is mandatory before assigning the function module to Inbound process code.
    For inbound processing you need to tell, whether the function will be capable of dialog processing. This is meant for those functions, which process the inbound data via call transaction. Those functions can be replayed in visible batch input mode to check why the processing might have failed.
    Fig 6.1
    Here the main characteristic is Input Type. It means “How are IDoc packages processed?” and having values like
    Input Type Short Text
    0 Mass Processing
    1 Individual input
    2 Individual input with IDOC locked in CALL TRANSACTION
    Also another property Dialog Allowed can be set here. With “Dialog allowed” IDocs can be processed in dialog mode.
    Fig 6.2 – BD51 Characteristics of Inbound Function Module
    Assigning a processing function
    The combination of message type and IDoc type determine the processing algorithm. This is usually a function module with a well-defined interface or a SAP business object and is set up in table EDIFCT.
    The entry made the points to a function module, which will be called when the IDoc is to be processed. The entries for message code and message function are usually left blank. They can be used to derive sub types of messages together with the partner profile used.
    Used transaction code WE57 for assigning function module to IDOC Type.
    Fig 7.1 WE57 – Assign Function Module to Message and IDOC Type
    Fig 7.2 Assign a handler function to a message/message type
    Process Codes
    R/3 uses the method of logical process codes to detach the Idoc processing and the processing function module. They assign a logical name to function instead of specifying the physical function name.
    The combination message type/IDoc will determine the logical processing code, which itself points to a function. If the function changes, only the definition of the processing codes will be changed and the new function will be immediately effective for all IDocs associated with the process code.
    For inbound processing codes you have to specify the method to use for the determination of the inbound function.
    The Inbound processing code can be attach to the function module using transaction code WE42
    Fig 8.1 WE42 – Define Inbound Process Code
    You need to tick, if your function can be used via the ALE engine. This is the option you would usually choose. It allows processing via the ALE scenarios. See fig below
    Fig 8.2 WE42 – Set properties of Inbound Process Code
    See fig 8.4
    Fig 8.3 WE42 – Set the Message type for the Inbound Process Code
    Fig 8.4 WE42 – Fill the details of the Inbound Process Code.
    The properties set in the above fig 8.4 are used for the workflow handling when the IDOC is having any error.
    Properties, which are useful in the workflow processing, are as follows.
    • Object Type – It is a business object created using transaction code SWO1 and used as a handler
    • Starting Event - Will triggered the workflow on occur of Error.
    • Ending Event - Will terminate the workflow after processing the
    Workflow Handling
    Refer: - Workflow Guide
    Create Inbound Partner Profile
    For each message type you need to maintain the inbound partner profiles. Maintain receiving system partner profile using WE20 (See fig. 10.3). Add the message type in the Senders inbound parameter.
    Following steps will be followed for creation of partner profile (Inbound).
    • Add the message type (e.g. ZEMPMSG) into the inbound parameter by clicking .
    Fig. 10.1 WE20 – Addition of message type in Inbound Partner Profile
    • On the next screen enter the message type , process code. In the Processing by function module block select the radio button based on the need. If you clicked on Triggered by background program then the IDOC will be collected and will triggered by another program which will run in background and if the second option Triggered immediately is clicked then the IDOC will be processed by the function module as soon as it is triggered.
    Fig. 10.2 WE20 – Inbound Parameters.

    Execution Steps for inbound Idoc:
    To execute inbound idoc go to Transaction we19 give the Idoc number execute the transaction
    It displays a screen with control, data, and status records. Click Standard inbound OR inbound function module buttons and process the idoc.
    i) Standard inbound:
    If you have selected the standard inbound button it displays a screen with the standard setup:
    II) Inbound function module:
    If you select the in bound function module button displays the below screen you can enter the function module name which you want to execute
    If you select Check box Call in debug mode you can execute the function module in debug mode.
    Call transaction Processing:
    In Background:
    The function module is called in the background
    This setting is only important if the function module to be called reacts accordingly to the importing parameter 'INPUT_METHOD'. This is therefore only valid for function modules which implement the application functionality using the command 'CALL TRANSACTION'.
    In foreground :
    The function module is called in the foreground.
    This setting is only important if the function module to be called reacts accordingly to the importing parameter 'INPUT_METHOD'. This is therefore only true for function modules which implement application functionality using the command 'CALL TRANSACTION'.
    In foreground After error:
    The function module is called in a background session. This becomes a session in the foreground after the first error has occurred.
    This setting is only important if the function module to be called reacts accordingly to the importing parameter 'INPUT_METHOD'. This is therefore only true for function modules which implement application functionality using the command 'CALL TRANSACTION'.
    Now it will post the idoc.
    Testing of Inbound Idoc:
    If you need to check the status of idoc Go to Transaction ZE05 give the idoc number in the idoc number select option execute the transaction.
    Then displays a screen with Out box and Inbox . select the idoc number in the Inbox Shows the control record , data record ,status record .select the status record and check for the idoc status Then you will be known the idoc is successful posted or not.
    The idoc which has been posted into SAP successfully will have the status 53.
    The list of the other valid status for Inbound Idoc are as follows:
    Status Message Description
    50 IDoc added
    51 Error: Application document not posted
    52 Application document posted
    62 IDoc passed to application
    64 IDoc ready to be transferred to application
    74 IDoc was created by test transaction
                                                                                    Process Steps for Outbound IDOC Programming
    The following steps are required for Outbound IDOC Programming.
    Common Steps
    The steps for new segment creation, new Idoc Type, new Message Type and linking between message type and Idoc Type are same as Inbound Idoc Programming. The detail Steps for such activities are mentioned in the Page 2 to Page 5.
    Create Outbound Partner Profile
    Use Transaction WE20 and select the Receiver Partner. Then add message type ZEMPMSG in the outbound parameters. The partner profile needs to be created at the ReceiverLogical System(LS)/Customer(KU)/Vendor(LI)/Bank(B)/Benefits provider(BP)/ User(US) only.
    Then double click on the Message type ZEMPMSG and it navigates to the following screen where user has to set the following attributes:
    • Receiver port as A000000001 for RFC
    • Packet Size field as 1
    • Idoc type Z_EMPMAT_IN in basic type field
    • Set the Syntax check box
    • Set the output mode as Transfer Idoc immediately
    • Save the changes.
    Coding Steps:
    1) Create an Executable Program Based on specification.
    2) All the Important Data should be displayed as Parameters with mandatory.
    i) Message type
    ii) Sender port
    iii) Sender partner
    iv) Sender partner function
    v) Receiver port
    vi) Receiver partner
    vii) Receiver partner function
    3) Select the data based on selection screen into an internal table.
    4) Read the selected internal table and fill the Header segment.
    5) Now Loop the internal table to fill other Segments.
    6) Fill the Control segment data.
    7) Call the proper Function module and pass the data to the function module
    To create the idoc.
    8) Change the status of idoc based on the function module return code.
    9) If FM return code is 0 set status to 03.
    10) See the demo program Z_IDOC_OUTBOUND_EMP for more Clarification.

    Hi Every Body,
       I m new to Interfaces(ALE/iDOC).Can u tell me the easy method to find out iDOCS ,How to know whether it is an outbound /inbound idoc? how develop a interface ? pls guide me with small example.
    i m waiting for ur reply........
    Thanx in Adv.
    Prabhas

    Hi,
    There are basically two types of IDOCs.
    Basic IDOCs
    Extended IDOCs
    Idoc Components
    Basic Idoc
    Basic IDOC type defines the structure and format of the business document that is to be exchanged between two systems.
    Extension Idoc
    Extending the functionality by adding more segments to existing Basic IDOCs.
    Creation of 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.
    Create IDOC Type
    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 “The table is cross-client (see Help for further info)”. 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 “The table is cross-client (see Help for further info)”. Press Enter.
    Click New Entries to create new Message Type.
    Fill details
    Save it and go back

  • Different between ALE, IDOC and BAPI?

    Hi Folks,
    What is the different between ALE, IDOC and BAPI? and send me the following steps?
    Thanks in advance.
    Siva

    Hi,
    please read the below lines.
    ALE
    ALE is SAP proprietary technology that enables data communications between two or more SAP R/3 systems and/or R/3 and external systems. When a new enterprise resource planning (ERP) solution such as R/3 is implemented, companies have to interface the ERP system with legacy systems or other ERP systems.
    ALE provides intelligent mechanisms where by clients can achieve integration as well as distribution of applications and data.
    ALE technology facilitates rapid application prototyping and application interface development, thus reducing implementation time.
    The ALE components are inherently integrated with SAP applications and are robust, leading to a highly reliable system.
    ALE comes with application distribution/integration scenarios as well as a set of tools, programs, data definitions, and methodologies that you can easily configure to get an interface up and running.
    BAPI
    BAPIs provide a stable, standardized method for third-party applications and components to integrate into the Business Framework. These interfaces are being specified as part of SAP's initiative with customers, partners and leading standards organizations. Also, SAP has implemented the emerging Object Application Group (OAG) specifications with BAPIs.
    Pros and Cons for both BAPI and Call Transaction
    BAPI
    One of the big plusses for BAPIs is that the interface and function are not supposed to change.  This is a big plus when you do upgrades or hot packs because the transaction can change (format, required inputs etc) which means you then need to update the call transaction.
    Some of the BAPIs are better documented and easier to use than others.
    You usually need to perform the BAPI that actually does the COMMIT after you call your BAPI.
    The Program coding for calling a BAPI is usually cleaner than setting up the screen flow etc for the Call Transaction.
    You don't need to worry about special data circumstances interrupting the normal data flow of the screens and causing errors because of that.
    BAPIs probably have better performance since they don't do the screen flow processing.
    In general if the BAPI exists for the transaction you want to perform and you can figure out how to use it the BAPI is probably the best way to go.
    This is just from my experience working with both BAPI and Call Transaction.  I have had some very good successes with BAPIs, but very occasionally found that I could not get the BAPI to perform the update I needed.

    Anki Reddy.

  • Roll Out,EDI,ALE,IDOC,BAPI

    HI FRNDS, HOW R U
    would u plz send me about the ROLL OUT means,
    what is mean of EDI,ALE,IDOCs&BAPI.
    what is the difference of these things& what is the use of these things
    thank u
    with regards
    nagesh

    Hi
    Roll out- Same client is having business in different countries.Instead of customizing again for the countries, we can copy the customizing from the parent country and configure all related to the country specific settings.
    EDI-Electronic Data Interchange (EDI) is about doing business and carrying out transactions with your trading partners electronically. EDI covers most things that are traditionally done using paper-based communication.
    ALE-ALE is SAP proprietary technology that enables data communications between two or more SAP R/3 systems and/or R/3 and external systems. When a new enterprise resource planning (ERP) solution such as R/3 is implemented, companies have to interface the ERP system with legacy systems or other ERP systems.
    ALE provides intelligent mechanisms where by clients can achieve integration as well as distribution of applications and data.
    ALE technology facilitates rapid application prototyping and application interface development, thus reducing implementation time.
    The ALE components are inherently integrated with SAP applications and are robust, leading to a highly reliable system.
    ALE comes with application distribution/integration scenarios as well as a set of tools, programs, data definitions, and methodologies that you can easily configure to get an interface up and running.
    BAPI -BAPIs provide a stable, standardized method for third-party applications and components to integrate into the Business Framework. These interfaces are being specified as part of SAP's initiative with customers, partners and leading standards organizations. Also, SAP has implemented the emerging Object Application Group (OAG) specifications with BAPIs.
    IDOC-IDoc (for intermediate document) is a standard data structure for electronic data interchange (EDI) between application programs written for the popular SAP business system or between an SAP application and an external program. IDocs serve as the vehicle for data transfer in SAP's Application Link Enabling (ALE) system. IDocs are used for asynchronous transactions: each IDoc generated exists as a self-contained text file that can then be transmitted to the requesting workstation without connecting to the central database. Another SAP mechanism, the Business Application Programming Interface (BAPI) is used for synchronous transactions.
    Assgn points if useful.
