Help in creation of XML file for IDOC postings

Hi All,
Need help if anyone has knowledge/experience in creating XML files for IDOC processing.
We need to design an input file (in XML format) for creation of IDOCu2019s for purchase Invoices through Interface.
We have an existing input file, which is working correctly.  We are trying to modify this existing input file for a new Tax Code (Non-deductible inverse tax liability).   This tax code is working fine for manual postings.   But, through IDOC, tax postings are not correctly triggering.
Could you please confirm if any one has experience on this, so that I can share more details for resolving.
Thanks & Regards,
Srini

Hello,
you can use CALL TRANSFORMATION id, which will create a exact "print" of the ABAP data into the XML.
If you need to change the structure of XML, you can alter your ABAP structure to match the requirements.
Of course you can create your own XSLT but that is not that easy to describe and nobody will do that for you around here. If you would like to start with XSLT, you´d better start the search.

  • Issue in Creation of XML file from ABAP data

    Hi,
    I need to create a XML file, but am not facing some issues in creation of XML file, the in the required format.

    Hi All,
    I am working in ECC 6.0. The system was configured to generate XML files for credit transfer as per SEPA guidelines. The files are being created in the application layer. But the line length is being restricted to 255 characters. As per the specifications of a XML file in apllication layer. all information should be contained in one single line.
    Secondly the job log for the payment medium creation program contains the below mentioned line among others -

    Can anybody tell me what is going wrong?

  • How to dpwnload one XML file for each report row

    Hi all,
    i have a report on the products table with about 1000 rows
    desc of table products
    product_id varchar (10)
    product_desc varchar2 (2000)
    I would like to download on the file system an xml file for each row of the report
    the nane of each xml file = <product_id>.xml
    thanks in advance
    km

    Hi,
    You would probably find it better to search on the PL/SQL forum as this is more their area than Apex.
    From what I can see in there (and there are a number of examples that would help you), you need to do something like:
    DECLARE
    vPATH VARCHAR2(50) := '/DEV';
    vFILENAME VARCHAR2(50);
    vFILE UTL_FILE.FILE_TYPE;
    BEGIN
    FOR C IN (SELECT PRODUCT_ID, PRODUCT_DESC FROM PRODUCTS)
    LOOP
      vFILENAME := C.PRODUCT_ID || '.xml';
      vFILE := UTL_FILE.FOPEN(vPATH, vFILENAME, 'W');
      UTL_FILE.PUT_LINE(vFILE, '<xdr>');
      UTL_FILE.PUT_LINE(vFILE, '<product_id>' || C.PRODUCT_ID || '</product_id>');
      UTL_FILE.PUT_LINE(vFILE, '<product_desc>' || C.PRODUCT_DESC || '</product_desc>');
      UTL_FILE.PUT_LINE(vFILE, '</xdr>');
      UTL_FILE.FCLOSE(vFILE);
    END LOOP;
    END;I haven't included exception handling etc and you should check on the PL/SQL forum to see if there are better examples!

    We want to install SAP Fiori Front-End (GW+UI) on the Sandbox system with SAP Netweaver 7.3.1. (SP14)
    Gateway component (SAP GW CORE 200 SP10) was installed without any problems.
    But I need to install UI-add-on (NW UI Extensions v1.0) and when I try to install it via SAINT, transaction said me that I need to generate xml-file for it (as in General notes for UI add-on mentioned).
    But I have Solution Manager 7.0.1 and in MOPZ for this version I do not have option  "install Add-on" as it written in Guide for ui add-on installation.
    Could you please help me with advice how to generate xml-file for UI add-on installation on SolMan v.7.0.1?
    If where is no way, but only to upgrade Solution Manager, maybe somebody could give me xml-file for your system (for NW 731) and I will change it to my needs, I will be very grateful!

  • How to create an XML File for Gantt?

    Hi Everybody.
    I need a Gantt in Web Dynpro ABAP. I need it for the boss to do a Forecast for Vacation. I Hope this is understanding.
    Did Anyone know how can i create a XML File for the Gantt at runtime?
    Thanks
    MSi

    Hi Marcus,
    the following link is to the JNet/JGantt developer doco
    [JNet/JGantt Developer Documentation|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/lw/uuid/f010ec31-9658-2910-3c83-c6e62904eceb]
    included in this is the:
    [Schema for XML|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/com.sap.km.cm.docs/lw/webdynpro/jnet_jgantt%20developer%20documentation/schema/xml-spy/jnet-schema.html]
    You can use this to build XML to represent a gantt like chart.
    I did this to build XML to represent employee avaliablity - although we fronted the gantt through WD Java not ABAP - the java applet called is the same (I believe).
    Don't underestimate the work required to tweek your data into a decent layout. It took me days.
    There may be tools/api to help generate the XML - I don't know of them - I'd look forward to seeing any other replies to this thread from people who have used/built any.  An example of a class that generates JNet XML - CL_SPI_UI_JNET - but this does not seem to be a Gantt display.
    Cheers,
    Chris

  • Mutiple mapping XML files for one datasource

    One of our projects raised the following question. Any help would be greatly appreciated.
    "Can we have mutiple ToplinkMappings.xml files for one database? The reason we are looking at it is, our toplinkMappings.xml file size is keep growing in size(right now 2.2MB), we are getting into issues while comparing with the previous versions. The PVCS diff tool and beyond compare tools are not able to interpret the corresponding blocks of code on both the versions properly."

    Hi Haiwei,
    Yes, you can have multiple deployment.xml files in a session. Take a look at Configuring Multiple Mapping Projects.

  • XML file for GigE Vision camera

    Hello,
    I am working on a design of GigE Vision camera. It should be very simple linescan camera. I implemented the whole required GigE Vision register set, can communicate with the camera in MAX. The problem is that I need to creata this XML file for the camera.There is this XML file here: 
    http://www.emva.org/cms/upload/Standards/GenICam_D​ownloads/SFNC_Reference_Version_2_0_0_Schema_1_1.x​...
    What should I do with it? My first version of the camera will have 2 funcions: turn it on and turn it off I am bit confused, because the xml file template has lots of functions, that I don't really need. Should I delete them? Or leave inside with default values? What does minimal configuration XML file need?

    Thank you very much! Perhaps I was too concentrated on digging through various documents and missed the important info.
    And one more question: how does NI software build the *.icd file? By reading XML file? Or by reading registers in my camera? 
    Both. The XML is processed by the GenApi software component which then translates it to register operations. The XML file thus controls what features are visible based both on the XML file as well as the camera registers (features in the XML may be conditionally available based on the <pIsImplemented< tag). Next, the IMAQdx ICD file contains the subset of features in the XML file that are available and are tagged as <Streamable>, meaning they can be saved to a settings file.

    What I am specifically after is: How can I change the default listening port for the Presentation Service? The default port is 9710 and I want to move to another port.<P>
    Also, how can I move the JavaHost from the default port 9810? I can change the file <i>OracleBI/web/javahost/config/config.xml</i> to reflect the change. Once the JavaHost has been restarted it starts up on the expected port, but the Presentation Service still tries to communicate over RPC to port 9810. How do I configure the presentation service to search for the JavaHost on a non-default port?<P>
    I have boiled it down to my original question: What are the possible values I can configure in the instanceconfig.xml file?<P>
    Any comments here would be great.<P>
    Cheers,<br>

    So, I had a little breakthrough here.
    I found in the OBIEE deployment guide, page 142:
    To change the Presentation Services listener port
    1 Open the instanceconfig.xml file for editing.
    2 Locate the <WebConfig> element.
    3 Within the <WebConfig> tags, create the element <RPC> and assign it the RPC Listener Port
    value for the BI Presentation Services instance, as shown in the following example.
    <WebConfig>
    <ServerInstance>
    <RPC>
    <Listener port="9715" />
    </RPC>
    </ServerInstance>
    </WebConfig>
    NOTE: In the preceding example, the RPC Listener port for the BI Presentation Services instance
    has been changed to port 9715 from the default of 9710.
    4 Save changes to the file.
    This almost works. The RPC element has been deprecated, as was reported in the sawserver.out.log:
    The configuration entry 'RPC/Listener' is deprecated. Please refer to the admin guide for more information.
    What I then did was to just remove the RPC elements and leaving the Listener element straight under there ServerInstance element. This seems to have solved the problem.
    I still have to figure out how to let the Presentation Service know that I have moved the JavaHost to antoher port ...
    Cheers,

  • How to generate an XML file for an animation of IK armature

    Can someone please tell me how to generate an XML file for an animation of IK armature.
    I have a 5 keyframe/16 frame animation of a human character made up of a series of moveiclip symbols that is animated with an IK armature.  I need the XML information from the animation. 
    When I go to Commands > Export Motion XML I get the error message "There is more than one object on frame 1" and then nothing happens.
    Thank you,
    c

    I hope that's not the case.  I want to write to adobe about it.  I think it's a great feature and it functions really well even though it is not a very developed IK tool.  My biggest issue with it is ouput options and integration with motion tweens.
    I have seen a lot of examples of animators using it online, just no one talked about output.  I just feel it hasn't been developed.  It can generate a sprite sheet but only for a single pose frame of the animation, and not all the key frames or pose tweens.  I find that functionality quite odd, as if adobe just forgot about IK when added in sprite sheets, etc. and the reason it half works is just an accident.
