    Hi,

    U can change in IDOC but follow the steps

    Hi,,

    2 Introduction

    Configuring IDoc adapter in Exchange Infrastructure 3.0 requires some configuration on the SAP

    systems, for both XI and the backend system where the IDoc message is to be sent. These steps, although

    simple, are many times missed or mis-configured, causing the delivery of messages to fail.

    Since IDoc adapter uses the ABAP stack, instead of J2EE, the configuration requirements are mainly in

    ABAP.

    Setting up IDoc adapters requires the XI integration server to be able to communicate with the backend

    SAP system, and also to make sure that the Logical System Name used when posting IDoc exists on the

    backend SAP system.

    3 The Step By Step Solution

    The basic steps for the IDoc configuration are outline below:

    1. Configure SM59 on XI to communicate to SAP backend system.

    2. Configure port on XI for IDoc communication.

    3. Create or verify the Logical System Name on the SAP backend system.

    4. Create or verify business system in XI’s System Landscape Directory.

    5. Verify the Logical System Name of the business system.

    6. Verify or add the Logical System Name for the sender business system.

    7. Create/configure the Communication Channel for the IDoc receiver adapter

    3.1 Configure SM59 on XI to communicate to SAP backend system.

    1. Using transaction SM59, create an RFC destination with Connection Type = “3”.

    In this example, the RFC destination name is “NDVCLNT510”.

    2. Enter the logon information:

    3. Test the connection by clicking on “Testing connection” and “Remote logon”.

    Both must be successful.

    3.2 Configure port on XI for IDoc communication.

    4. Go to transaction IDX1 on XI, and create a port. In this example, the Port name is “SAPNDV”.

    • The Port name must be in the form of “SAPxxx”, where xxx is the system ID of the backend SAP

    system.

    • The Client must be the client number of the backend SAP system.

    • Select the RFC Destination which was created in the previous step.

    3.3 Create or verify the Logical System Name on the SAP backend system.

    5. Enter transaction SALE on the SAP backend system.

    6. Create or verify the Logical System Name. In our example, NDVCLNT510 is verified.

    3.4 Create or verify business system in XI’s System Landscape Directory.

    The business system name for the SAP backend system must contain a valid Logical System Name. This Logical System Name is the one verified or created in the previous step.

    7. In the System Landscape Directory, select the SAP backend business system. If one does not exist, then create the business system. Verify the Logical System Name.

    3.5 Verify the Logical System Name of the business system.

    8. In the Integration Directory, doubleclick on the business system (in our example, it is NDVCLNT510).

    Navigate the menu:

    Service • Adapter Specific Identifiers.

    If information is empty or incorrect, then it will have to be synchronized with the content of the System Landscape Directory. Follow the steps below for synchronization.

    9. (Optional) Synchronization of the business system in Integration Directory to the business system in System

    Landscape Directory.

    • Double-click on the business system in the Integration Directory.

    • Switch to Edit mode.

    • Select menu: Service • Adapter-Specific Identifiers

    10. (Optional) Within the dialog box, click on the button as indicated below to resynchronize.

    11. (Optional) If the expected data from the System Landscape Directory is not updated, then the SLD cache may need to be cleared first.

    3.7 Create/configure the Communication Channel for the IDoc receiver adapter.

    15. In the Integration Directory, create an IDoc receiver communication channel.

    • The RFC Destination is from step 3.1.

    • The Port is from step 3.2.

    NOTE:

    There is no need to create an IDoc sender Communication Channel for XI. Instead, the backend SAP system must be configure to send the IDoc to XI.

    4 Appendix

    Transaction: IDX2

    There are a couple of situation where IDX2 can be useful on the XI system.

    1. When we want to test connection between the XI and SAP backend system.

    2. When an IDoc has changed, and the meta data stored in XI needs to be update. When an IDoc is sent from the SAP backend system to XI, XI will first check to see if the meta data for the IDoc is already in its persistent cache. If not, then XI will use the configuration in IDX1 to retrieve the IDoc meta data from the backend system. If the

    meta is already in cache, then it will NOT do so. Therefore, when an IDoc has changed, it is necessary to manually update the new meta data on XI, or delete it from the cache, so that the latest version can be retrieved. IDX2 is used for this purpose.

    Go to transaction IDX2 and click on “Create”.

    Enter the IDoc Type and the Source Port as defined in step #2. Click “Continue”.If successful, the following will show up. If error occurs, then the IDX1 configurations will need to be re-checked.

    Reward points if find useful.

    JP,

    Its not possible. You have to make changes in R/3 side and have to re-import the IDOC. In case if you add fields don't worry the existing mapping you defined will not go, so now u can define the mapping for new fields alone.

    Best regards,

    raj.

    You can add additional segments/fields into IDOC, however you would need to import these into XI via IDX2 and import into Integration Builder.

    I am currently working on similar.

    As Raj says, you need to do this in the R/3 system (and then import the same into IDX2 in XI ABAP STack)

    JP,

    You can not modify IDOC structure in XI. Instead you need to add fields using WE30 & WE31 in R/3 system. Then you need to import the IDOC to XI again & you need to do entire configuration in XI again.

    You need to follow following steps.

    1. Enhance(Extend) the IDOC structure in WE30 & WE31 in R/3 system. The msg type of IDOC wil be changed now as it wil be a custome IDOC (Standard but with extended fields.)

    2. You need to maintain ALE setting as per new Message type in R/3 now.

    3. Import the New IDOC structure in XI.

    4. Do all mapping & interface mapping again with your file sturcture.

    5. Do all ID configuiration again with new message type.

    With all this changes your scenario will work.

    Hope it helps.

    Regards

    Sushil

    Hey

    make the necessary changes in IDOC on the R/3 side,then re-import the IDOC in IR,update the IDOC metadata ,t-code IDX2 ,perform the correct mapping and ur done

    thanx

    HI JP

    It is not possible. You will do the changes in R/3 side and you can reimport the idoc in XI. and do the mappings if necessary..

    Cheers..
