File Upload on Trex System

Hi,
We have requirement , to upload csv file into TREX system. Inorder to achieve it , we have done the following.
1. Create a CSV file with the required attributes and attribute values.
2. Created Data source type as "File Export"
3.Using report CRM_MKTTG_FDS_LOAD_FILE_UI, we have uploaded the file on the TREX System and the file path - D:\usr\sap\T71\TRX01 but we are not sure where is the file stored on TREX system
Query - 1 How to know TREX system has access to created CSV file.
                 We need to know where exactly this file is stored on the TREX system. Is there a way to check the location.
Query -2 : While creating Data Source for High Volume Segmentation : We have to enter " Description of the TREX Attribute ,Data Element and Name of the Trex Attributes.
But we are not sure how the mapping is done between the File and Trex server.
Please let us know any information on the above.
Thanks
Brahmaji

Hi Brahmaji,
I request you keep these in mind before uploading the file.
a. The header of the file should have names similar to the attribute names of the Datasource.
b. There should be atleast one field with Business Partner Guid(e.g. BPARTNER in the datasource)
c. The fields should be mapped to correct data elements (e.g. CRMT_MKTHV_FIDS_GUID32 corresponds to BP Guid).
d. While running the report CRM_MKTTG_FDS_LOAD_FILE_UI the filename
field should point to the path where the file is residing in the TREX
machine.(e.g. /usr/sap/STD/TRX10/temp/<filename>
Hope this helps you.
Best Regards,
Anup

  • How are files uploaded to the file system?

    How are files uploaded to the system? I do not see any documentation on the SAP Cloud Appliance Library regarding this.

    Hi Daniel,
    the majority of the appliances run the Linux operating system. You can use native scp (Linux) or winscp (Windows) to upload files to the file system.
    If you google for "upload data to Linux aws instance" you should find a lot of documentation on the topic.

  • FLAT FILE UPLOAD INTO BI

    Hi,
    What kind of questions are needed to be asked (from client) for requirements gathering for a flat file upload (from legacy system) to BI? Basically what are all the questions that i need to ask them to make sure I have all information for designing a flat file extractor?
    Thanks

    I would ask them what do they want to report on from the legacy system and is data already in R/3?  I would also ask what kind of data is stored in the legacy system .... inventory, financial data, sales, etc ... Once I knew that, I would ask what do they want to report on .... stock quantities/costs, gl account data, revenue, deliveries, etc....
    Then I would ask, do you want this to be seperated from the R/3 datastream?  More than likely this will be yes, if not, fight to keep it seperated and possible in it's own cube/ODS and combine in a multiprovider (you need to use the same 0material, 0customer, 0vendor, 0gl_account info objects if you want to combine nicely on a multiprovider).
    If the database the legacy system is on is either SQL Server or Informix or Oracle, you may want to consider DBConnect and connect directly to their tables.
    In all cases, I try to avoid bringing everything in "just because we may need it".  If the system is legacy and it's been a legacy for 2 years, see what people keep going back for and grab that data only.  If someone claims to need data, but have not sought it out for 2 years, then the probably don't need it.
    Also, check the granularity of the data.  Do they need individual documents for legal reasons?  Can you summarize the data?  What are they going to use the data for?

  • How to upload a file in R/3 system through RFC using WebDynpro Java

    Hi There,
    we need to pass a file(mostly xml) using file upload feature in Webdynpro and then need to pass the file in R/3 system using RFC. What should be importing parameters for RFC and how should i implement the fileUploadUi in this case.
    I have already seen example of how to add this in a table input form.
    Any pointers will be great help.
    Regards,
    Sudhir

    Use this code to convert the file content to bytes in WDJ:
    Apart from the resource context attribute create a context attribute of type binary.
    get the data from resource & convert it to binary & pass that to RFC. U can use this code for conversion
    byte fileData[] = null;
    try{
    InputStream fileIs = wdContext.currentAttachCVElement().getFileData().read(false);
    ByteArrayOutputStream bOut = new ByteArrayOutputStream();
    int length;
    byte[] part = new byte10 * 1024;
    while ((length = fileIs.read(part)) != -1) {
    bOut.write(part, 0, length);
    fileIs.close();
    fileData = bOut.toByteArray();
    bOut.close();
    } catch (Exception e) {
    wdComponentAPI.getMessageManager().reportSuccess(e.toString());
    Here getFileData reffers to the attribute of type resource. rest of the code u can use directly.
    Use this code in your R/3 function module to convert the data.
    *" VALUE(XCONTENT) TYPE XSTRING OPTIONAL
    OUTSTRING TYPE STRING,
    CONV TYPE REF TO CL_ABAP_CONV_IN_CE.
    Convert data passed from WD Application.
    CONV = CL_ABAP_CONV_IN_CE=>CREATE( INPUT = XCONTENT ).
    CONV->READ( IMPORTING DATA = OUTSTRING ).
    SPLIT OUTSTRING AT CL_ABAP_CHAR_UTILITIES=>CR_LF INTO TABLE IT_DATA.
    DELETE ADJACENT DUPLICATES FROM IT_DATA.
    Let me know if you run into issues, please award points accordingly.

  • Error in file upload. There is not enough space in the file system

    Hello,
    The excel file upload functionality was working fine till now. there is error for all the users that there is no space in file system
    Kindly help, is this basis issue ?
    thank you
    B

    Hi ,
    Please verify on the space in temporary directory which is used on server side (on the engine where this webdynpro java application is running)
    When file is up loaded WD java runtime uses temporary directory of Java runtime to store/read this data .
    Clear all temporary directory folders/check whether directory has Read/Write permission(OS level ) assigned to it .

    Hi Vijay,
    Thanks for the quick reply.
    I have gone through the notes 1535201  & now on 1606563  after your advise.
    Both the notes says the fix is available on 7.01 after SP 07 and we are on SP 14 already.
    Also just in case I did checked with our basis and they confirmed we are a head and we have the above notes in our release already.
    Unfortunately the notes are not the solution to the investigation till date.
    Thanks,
    Sai

  • Unable to install File Upload Utility in AIX system

    Hello,
    I installed the Forms File Upload Utility, through CGI, following the steps described in the html
    document provided with the utility. That is:
    - i copied the files UploadClient.jar.sig and UploadServer.jar to the directory
    /ias102/6iserver/forms60/java;
    - i edited the .profile file, for the variable CLASSPATH to include the forms60/java directory:
    CLASSPATH=/ias102/6iserver/forms60/java:/ias102/6iserver/forms60/java/UploadServer.jar:/ias102/6iserver/discwb4/classes/locator.jar:/usr/java131/jre/lib/rt.jar:
    - i edited the .profile file, for the variable PATH to include the requested directories (Forms \bin and \bin\classic):
    PATH=/ias102/6iserver/lib:/ias102/6iserver/bin:/usr/java131/jre/bin/classic/:/us
    r/java13
    1/bin:$PATH
    (i also tried editing the CLASSPATH and PATH variables in the forms60.sh and forms60_server files)
    - on my machine (client machine) i installed the PJC.x509 certificate;
    After this installation, i included the Demo Form provided with the utility in my test application, and then i executed
    the form.
    I tried to upload a file but i got the following error: "FRM-40735: WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-06508"
    I looked in the html document, in the "Troubleshooting" section, and i did a test pressing
    the Key-Listval (Control+L by default), that would pop up a dialog containing
    the current CLASSPATH, but instead i got the following error:
    "FRM-40735: KEY-LISTVAL trigger raised unhandled exception ORA-105100."
    In the html said that "If this fails then this is because Forms cannot instanciate any Java code
    at all".
    Do i need to add any more environment settings?
    Thanks, Jorge

    There are probably several environment variables which need to be set in order for the Forms runtime to communicate with Java. However, to where they point will depend on which Java home you choose to use. For Forms 6.x, you must use the equivalent of JDK 1.1.8 or 1.2.2. These versions are included in the Oracle home. If you try using a newer version (like the one installed on the OS) you will likely have problems.
    Verify these env variables point to the appropriate locations to use the jdk/jre in the Oracle Home:
    PATH
    CLASSPATH
    LIBPATH
    LD_LIBRARY_PATH
    JAVA_HOME
    Additionally, ensure that your CLASSPATH includes references to the following jar files:
    importer.jar
    rt.jar

  • Error "A web exception has occurred during file upload" when trying to import ESXi image file into Update Manager

    I'm encountering this error and not sure how to fix, I'm quite new to vCenter so please bear with me.
    I'm trying out vCenter 5.1 with Update Manager 5.1 right now.  No license key has been entered and I still have 50 odd days to try it out.
    2 ESXi hosts are being managed by this vCenter, and they're both running ESXi 4.0
    I'm looking to use Update Manager to try to upgrade the ESXi 4.0 hosts to ESXi 5.1
    I downloaded the image file VMware-VIMSetup-all-5.1.0-799735.iso from VMWare website, and is looking to import it using the Update Manager so I can update the ESXi hosts, but I keep on getting the error:
    File name:     VMware-VIMSetup-all-5.1.0-799735.iso
    Failed to transfer data
    Error was: A web exception has occurred during file upload
    I tried importing it by using vSphere client to connect to vCenter server both remotely and locally, with firewall disabled.
    I've read http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1026602
    I've disabled firewall, and there is no anti-virus program on the server.  I've also restarted the machine several times, to no avail, I didn't reinstall update manager because the whole Windows and VCenter installations are clean from scratch.
    I logged into the vSphere Client using Active Directory credentials, and I've made all Domain Admins (which my account is a member of) part of the administrator group on the vCenter server. I can't log in using admin@System-Domain because it tells me I don't have permissions for it, I still haven't really had the chance to figure out why that is and not sure if that makes a difference.
    Also, I'm fairly certain I'm using the right image file, as I've burned some DVD's used that image file to upgrade some other ESXi hosts.  Unless there's a special image file I need to download?
    I'm at lost on what I can do to make it work.  Please advise.
    Thanks.

    The ISO file you mentioned is the one for vCenter Server. What you need is the "VMware-VMvisor-Installer-5.1.0-799733.x86_64.iso" (or VMware-VMvisor-Installer-201210001-838463.x86_64.iso) for the ESXi host.

  • Threading problem during File Upload with Apache faces upload tag

    First I am going to tell you "My Understanding of how JSF Apache Upload works, Correct me if i am wrong".
    1) Restores View (to show Input box and Browse button to facilitate users to select a file for upload)
    2) Translates Request Parameters to Component Values (Creates equivalent components to update them with request values).
    3) Validates Input(Checks to see whether the User has input the correct file)
    4) Updates Backing Bean or Model to reflect the values.
    5) Renders response to user.
    I am uploading huge files of sizes 400MB and above with the help of JSF apache extensions tag
    <h:form id="uploadForm" enctype="multipart/form-data">
    <x:inputFileUpload style="height:20px;" id="upload" value="#{backingbean.fileContents}" storage="file" size="50" />
    </h:form>
    In the backing bean
    private UploadedFile fileContents;
         public UploadedFile getFileContents() {
              return fileContents;
         public void setFileContents(UploadedFile fileContents) {
              System.out.println("File being uploaded...");
              this.fileContents = fileContents;
    Since, the file size is so huge, I am using temp folder to use for the apache tag instead of memory.
    In web.xml i am using like this
    <filter>
    <filter-name>ExtensionsFilter</filter-name>
    <filter-class>org.apache.myfaces.component.html.util.ExtensionsFilter</filter-class>
    <init-param>
    <param-name>uploadMaxFileSize</param-name>
    <param-value>600m</param-value>
    </init-param>
    <init-param>
    <param-name>uploadThresholdSize</param-name>
    <param-value>10m</param-value>
    </init-param>
         <init-param>
    <param-name>uploadRepositoryPath</param-name>
    <param-value>/uploadfolder/</param-value>
    </init-param>
    </filter>
    <filter-mapping>
    <filter-name>ExtensionsFilter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
    </filter-mapping>
    The upload process is working perfectly fine.
    Now coming to the problem:
    Suppose one user is logging into the application & uploading say 400MB of files.
    Until these files are linked to the model objects as my understanding of step 2, if second user tries to open the application he gets stuck with the loading page.
    The page gets loaded only after the request files are linked to the component values(Step 2 above) and updates the backing bean's values.
    I don't see any error in the logs. User is getting stuck. The user is getting stuck only when uploading the files. The other operations like searching are not blocking any other activities performed by the user.
    Server used: IBM Application Server V6.0. CPU is normal, memory usage is normal.

    Dear friend,
    i am also trying to upload using the common file upload.
    when try to run the file error is coming
    can give some suggestion.
    can i use if concurrent user file upload at a time

  • File Upload.. Strange Problem..

    im trying to read file data and print it in the browser. I dont want to save the file. just to read the uploaded file which is TAB delimited..
    First time it works fine. but If I browse back button and reload another file and submit. I am getting content of first file and second file. I closed the browser and reopened it but still problem is not resolved. it keeps on adding file content instead of showing current uploaded file. I dont know what to do.
    here is my code

  • Calendar & File Upload Components - Threadinar6

    Hi All,
    This is the sixth in the "Threadinar" series , please see Threadinar5 at
    http://swforum.sun.com/jive/thread.jspa?threadID=99473 for details
    In this Threadinar we will focus on the
    "Calendar" and "File Upload" Components
    Let us begin our discussion with the Calendar Component.
    Calendar Component
    You can drag the Calendar component "calendar component icon" from the Palette's Basic category to a page open in the Visual Designer to create an entry field with an integrated calendar pop-up to help the user pick dates for the field.
    You can also drop the calendar on a container component, like a table cell or group box.
    After dragging the component to the Visual Designer, you can work with the following useful properties of the Calendar Component:-
    General
    * id. Type: String
    The name of the Calendar component in the page bean and the JSP file.
    Appearance
    * columns. Type: int
    The number of character columns used to render the component. The default value is 20.
    * dateFormatPattern. Type: String
    The format of the date to be entered by the user. It is not usually necessary to set this property because a pattern is chosen automatically based on the locale.
    If you prefer to specify a date format, click the ellipsis button (...) to the right of the property and select a predefined date format from the property editor's list. You can also add your own formats. If you add a format, the values you can enter are limited to some combination of yyyy for the year, MM for the month, and dd for the day separated by separator characters. Typical separator characters are / (slash), . (period), and - (dash). For example, the following date formats are acceptable:
    o MM/dd/yyyy
    o yyyy.MM.dd
    o MM-dd-yyyy
    * dateFormatPatternHelp. Type: text
    Text that appears below the date entry field and shows the format pattern that the date entry field accepts. If you have not set the dateFormatPattern property, the help text is chosen automatically for you. If you have set the dateFormatPattern property, you should bind the dateFormatPatternHelp property to a localized string that matches the setting for each locale you want to support.
    * label. Type: String
    A label that appears next to the text entry field, typically describing what the user is supposed to enter.
    o Note: The label property is not as flexible as the Label component. You can use the Label component if you want more control over the label's appearance, such as positioning of the label relative to the component.
    * labelLevel. Type: int
    A number that affects the appearance of the label. 1 (Strong) is larger and bold. 2 (Medium), the default, is smaller and bold. 3 (Weak) is smaller and normal (not bold). This property takes effect only if the label property is set.
    * style. Type: String
    Cascading Style Sheet rules (CSS level 2) to be applied to the component. For example:
    position: absolute; left: 288px; top: 312px
    You can enter values directly or click the ellipsis (...) button to use the Style Editor.
    o Note: This property overrides any settings in the theme or the project CSS file for this component. If a style specified in this property does not appear to take effect, it is because an area of the component is obscured by a child component that has different style settings.
    For a list of CSS2 style attributes, see the web page at
    http://www.w3.org/TR/REC-CSS2/propidx.html
    * styleClass. Type: String
    A space-separated list of CSS2 style classes to be applied when the component is rendered. The style classes must be defined in the project's style sheet or in the theme's CSS file. If you click the ellipsis button (...), you see a list of all styles you can add to this property. For information on adding CSS classes and rules to the project's cascading style sheet, see CSS Editor.
    o Note: See the note above under the style property description for an explanation of why a class added to this property might appear to have no effect on the component.
    o Note: If you add a CSS style class from the current theme to your project CSS file and you redefine the style class, the change affects all components that use this style class. However, you can add your own style classes to the project CSS file that redefine the default style classes, and then when you add them to this property, the changes affect only this instance of this component.
    For the defaulttheme.jar CSS style classes for this component, see Calendar Component CSS Classes.
    Data
    * maxDate. Type: java.util.Date
    The last date that the user can select. The default value is four years from the date set in the minDate property, for a total span of five years.
    * minDate. Type: java.util.Date
    The earliest date that the user can select. The default value is the value of the selectedDate property, which defaults to the current date if that property is not set.
    * required. Type: boolean
    If selected, the user must enter a value for the calendar before the page can be submitted. If you add a Message component to the page and link its for property to this component, an error message will be displayed if the user tries to submit the page without entering a value.
    * selectedDate. Type: Date
    A java.util.Date object representing the calendar date selected by the user. If you right-click the component and choose Bind to Data, you can bind this property to a data provider or object that can process the user entered value on the server.
    When the component displays initially, if this property is not set, its value defaults to the current date. If you provide values for minDate and maxDate, you can also provide a value for this property that initially displays a date in that range.
    * validator. Type: MethodBinding
    Indicates the JavaServer Faces validator that is called when the value is submitted. A validator ensures that the correct value is entered by a user. Choose a validator from the drop-down list. If you choose (null), no validator is called. If you choose a validator, also select the required property to ensure that the validator is used. For descriptions of JavaServer Faces validators, see the list of topics at List of Validators.
    o Note: If you define your own validate method, for example, by right-clicking the component and choosing Edit Event Handler > validate, any value you might have set in this property is overridden.
    File Upload Component
    You can drag the File Upload component "file upload component icon" from the Palette's Basic category to the Visual Designer to create an entry field and a browse button that opens a file chooser dialog on the local system, enabling the user either to select a file or to type a file name into the entry field. When the page is submitted, a copy of the file's contents is sent to the web application.
    The component is similar to an HTML <input type="file"> element.
    * Note: This component is neither supported by nor available in portlet projects due to security reasons.
    * Note: The size of the component in the Visual Designer might not match the size of the component when it is rendered in a web browser, making the component appear to line up correctly in the Visual Designer, but not when the page is rendered in the user's web browser. Also, the rendering of this component can differ depending on the web browser. Be sure to test the component in the web browsers that you expect your users to use. For example, if you add a width setting to the style property that is smaller than the setting in the columns property, Internet Explorer observes only the width setting, while the Mozilla browser ignores it and sets the width according to the number of characters in the columns property.
    The File upload component uses a filter, a com.sun.rave.web.ui.util.UploadFilter object that is configured for you in the web application's deployment descriptor. The UploadFilter uses the Apache commons fileupload package. You might need to change these settings in the following two cases:
    * The server holds the uploaded file in memory unless it exceeds 4096 bytes; otherwise, the server holds the file contents in a temporary file. You can change this threshold by modifying the sizeThreshold parameter for the UploadFilter filter entry in the web application's web.xml file.
    * By default, the File Upload component can handle files up to one megabyte in size. You can change the maximum file size by modifying the maxSize parameter for the UploadFilter filter entry in the application's web.xml file.
    o
    A negative value for the maxSize parameter indicates that there is no file size limit. Setting the parameter to a negative value is not recommended for security reasons. For example, if you allow unlimited file sizes, a malicious user could mount a denial of service attack on your site by using extremely large files
    * To change the settings for the UploadFilter object in the web.xml file:
    1. In the Files window, expand project-name > web > WEB-INF.
    2. Double-click the web.xml node to open the file in the XML editor.
    3. Click the Filters toolbar button.
    4. In the UploadFilter section under Initialization Parameters, you can change the values for the maxSize and sizeThreshold parameters.
    The contents of the uploaded file, together with some information about it, are stored in an instance of com.sun.rave.web.ui.model.UploadedFile. By using this object, you can get the content of the file as a String or write the contents to disk, as well as get properties such as the name and the size of the file. In the interest of conserving memory, the contents and file data are only available during the HTTP request in which the file was uploaded. To access the contents of the uploaded file, bind the uploadedFile property to a bean property of type com.sun.rave.web.ui.model.UploadedFile. Have the setter or an action method process the file.
    The UploadedFile interface has methods for getting the name and size of the file, determining the file's MIME type (such as text/plain or image/jpeg), getting the file's contents as bytes or as a String, and writing the contents to disk. To learn more, in the Java editor, right-click on UploadedFile in a declaration statement and choose Show JavaDoc from the pop-up menu.
    * To set the component's properties, select the component and edit its properties in the File Upload Properties Window.
    * Right-click the component and choose one of the following pop-up menu items:
    o Edit validate Event Handler. Opens the Java Editor with the cursor positioned in the component's validate method so you can insert code to validate the value of the component.
    o Set Initial Focus. Gives this component focus when the user opens the page.
    o Auto-submit on Change. Causes the form to be automatically submitted if the value of the component changes. Sets the component's JavaScript onclick property to common_timeoutSubmitForm(this.form, 'component-id');. At runtime, this code causes the form to be automatically submitted if the user changes the component value. Once the form is submitted, conversion and validation occur on the server and any value change listener methods execute, and then the page is redisplayed.
    A component configured to Auto-submit on Change can use virtual forms to limit the input fields that are processed when the form is submitted. If the auto-submit component is defined to submit a virtual form, only the participants in that virtual form will be processed when the auto-submit occurs.
    o Bind to Data. Bind the component's text property to an object or to a data provider. For more information, see Bind to Data Dialog Box.
    o Property Bindings. Bind any of the component's properties to an object or data provider, such as the uploadedFile property to a bean property of type com.sun.rave.web.ui.model.UploadedFile.
    o Configure Virtual Forms. Enables you to add the component to a virtual form.

  • HELP! File Upload Servlet and Internet Explorer

    Hello people. I hope this is an easy problem to solve...
    I have a servlet upload program that works using Mozilla browser (www.mozilla.org), but for some reason it doesn't work using Microsoft IE. The servlet is also using the servlet upload API from Apache (commons).
    I'm using IE version 6.0.2800.1106 in a Win98SE host computer. I get a cannot find path specified error message (see below). At work, I also get the same error message using IE, but don't know what version. The OS is XP. Unfortunately, at work, I can't install Mozilla browser (or any software-company policy) to see if Mozilla works there too. I would've like to have tested to see if the upload program worked on Mozilla on a truly remote computer.
    So I figured, it must be a IE configuration issue, but darn it!! I began by resetting IE to default settings, but still have the problem, I played around with several different combinations of settings in "Tools"-->"Internet Options...", and I still get the error message. Someone PLEASE HELP ME!!!
    Dunno, if it will help, I've also pasted the upload servlet source code below and the html file that's calling the upload servlet, but you still need the Apache commons file upload API.
    Trust me on this one folks, for some reason it works for Mozilla, but not for IE. With IE, I can at least access web server, and therefore, the html file that calls the upload servlet , so I don't think it's a Tomcat configuration issue (version 5.0). I actually got the code for the file upload servlet from a book relatively new in the market (printed in 2003), and it didn't mention any limitations as far as what browser to use or any browser configuration requirements. I have e-mailed the authors, but they probably get a ton of e-mails...
    Anyone suggestions?
    Meanwhile, I will try to install other free browsers and see if the file upload program works for them too.

    I'm guessing what is happening is that Mozilla tells the servlet "here comes the file myfile.zip". The servlet builds a file name for it:
        String path = sc.getRealPath("/files");
        // path is now C:\TOMCAT\webapps\MyWebApps\files\
        fi.write(new File(path, fi.getName()));
        // append myfile.zip to "path", making it C:\TOMCAT\webapps\MyWebApps\files\myfile.zipIE, however, tells "here comes the file C:\WINDOWS\Desktop\myfile.zip". Now imagine what the path+filename ends up being...
    So what you want to do is something along the lines of (assuming Windoze):
    public static String basename(String filename)
        int slash = filename.lastIndexOf("\\");
        if (slash != -1)
            filename = filename.substring(slash + 1);
        // I think Windows doesn't like /'s either
        int slash = filename.lastIndexOf("/");
        if (slash != -1)
            filename = filename.substring(slash + 1);
        // In case the name is C:foo.txt
        int slash = filename.lastIndexOf(":");
        if (slash != -1)
            filename = filename.substring(slash + 1);
        return filename;
        fi.write(new File(path, basename(fi.getName()));
        ....You can make the file name check more bomb proof if security is an issue. Long file names trying to overflow something in the OS, NUL characters, Unicode, forbidden names in Windos (con, nul, ...), missing file name, ...
