    IDOC structure.

    It has Control Record , Data record and status record.

    All the informations like IDOc number, Sender, Receiver, Partner,Message type will be in Control Record. An IDOC will have only on eControl Record.

    All the data segments will be in Data record. It can be many.

    Status informations will be stored in Status record.It can have many status.

      Good Question??

      The data should be stored in form of segments in IDOC(data container).

      by using EDIDD structure u can store the data in these segments..

      it contains fields SEGNAME and SDATA...

      SEGNAME is for segment name

      SDATA is for the FIELDS what r defined in segment..

      Regards,

      Kishore.

    If u want to know about the segments practically means

    first go to transaction WE30 enter ur IDOC type (Eg.orders05).

    Now click the display button u can see all the segments there.

    copy one segment now goto transaction WE31 .

    Paste tht segemnt and see wat all fields involved in tht segment.

    (Eg E1EDK01 see this segement in tht double click E2EDK01005 and see the fields)

    Segements contains data.

    Hope this will be usefull.

    <b>Hi,

    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.

    NOTE:

    For debugging purposes, use transaction WE05 (IDoc overview) to see check your IDoc status, or to see whether an IDoc was created/

    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

    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.

    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.

    Execution Steps

    To execute the outbound idoc Go to SE38 &#61672; Give the program name and fill the Selection screen and execute it.

    Testing of Outbound 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 Outbox 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 successful will have the status 03.

    The bellow are the some of the Out bound status:

    Status Message Description

    01 IDoc created

    02 Error passing data to port

    03 Data passed to port OK

    29 Error in ALE service

    30 IDoc ready for dispatch (ALE service)

    31 Error - no further processing

    Change Pointers & Reduction of IDOCs.

    Applications, which write change documents, will also try to write change

    pointers for ALE operations. These are log entries to remember all modified

    data records relevant for ALE. The change point is used for extending or reducing the Idoc structure.

    Following Steps must be followed in case of Change Pointer.

    1) Goto Transaction BD60.

    Note down the Details of the Message Type for which change pointer has to activate. Details like Function Module, Classification Object, ALE object Type etc.

    E.g. ZDEBP3

    2) Next step is goto transaction BD53

    Click on change button.

    First select the segment for which the fields has to modified (either remove or

    add ).

    It will show the fields in a pop-up window where the user can select, deselect the respective fields.

    Save the settings for the Message type. Don’t forget to deactivate and activate the change pointers by clicking Deactivate change pointer and Activate Change pointers button on the main screen. It is mandatory to first Deactivate the change pointer and then activate it.

    Fig 1 Fig. 2

    Do not save the changes in the same transport request. Create separate transport request, which will be not transported. This is because once you transport the changes then it will not allow you to do the changes on the server on which it has transported.

    3) Once the activation is done system will reset the settings for the Message type in Change pointers (BD60). Maintained the old settings for the Message type like Function Module, Classification Object, and ALE object Type etc.</b>

    Hi Kanath,

    IDOC structure is nothing but a structure to carry the data in the specified format.

    Tcode is we30. Another way of explaning is Group of segments put together in the skeleton way forms the IDOC structure.

    Segment is group of fields put together like table or structure. Tcode for segment is WE31.

    IDOC type - Skeleton

    IDOC - The actual data.

    This IDOC caontains

    Control record - It is like Header data

    Data Record - This is like Item data

    Status Record - This contains the status Records

    Hope this helps

    Regards

    Arun
