  • HOW TO CREATE A NEW J2EE APP FOR DEPLOYING ORACLE REPORTS USING JDEVELOPER?

    Hi,
    I'm new to JDeveloper and Java, JSP etc. I'm trying to deploy a sample parameter form for JSP report. My question is: When I create a J2EE application using JDeveloper, how to make sure "The WEB-INF directory must contain the JSP tag library for Oracle Reports, called reports_tld.jar"? How to do it via JDeveloper?
    In my JSP page, I use <%@ taglib uri="/WEB-INF/lib/reports_tld.jar" prefix="rw" %>.

    Does anyone know the answer to this question?
    I get the following error in Jdeveloper when running my test jsp report:

  • How to Create an iView under Home in Standard User Role

    Hi,
    Can anybody guide me how to create an iView under Home which access the content available from Windows Share folders on a non SAP system.
    Its not URL iView , I wanna create an iView to access the content from a windows system (
    share)
    Thanks

    You have to create a File System Repository Manager under System Admin -> KM Admin. You can access any Windows Shared drive through that File System Repository manager. The shared folder would be displayed in your portal like a KM folder. You can easily create a KM Navigation iView (from template) over that folder and achieve your goal.
    Please see <a href="http://help.sap.com/saphelp_nw04/helpdata/en/e3/92322ab24e11d5993800508b6b8b11/content.htm">THIS</a> for the complete documentation on how to do this step by step.

  • How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!

    How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!
    I want to know how to create a backup file (because I'm pretty new with itunes, and it's hard to use it for me still), how to store my app data/media/videos, etc. And how I can retrieve them back when I'm done with the app I tried on my friend's computer.
    If anyone can help, it'd be great! Thank you so much!

    Sure-glad to help you. You will not lose any data by changing synching to MacBook Pro from imac. You have set up Time Machine, right? that's how you'd do your backup, so I was told, and how I do my backup on my mac.  You should be able to set a password for it. Save it.  Your stuff should be saved there. So if you want to make your MacBook Pro your primary computer,  I suppose,  back up your stuff with Time machine, turn off Time machine on the iMac, turn it on on the new MacBook Pro, select the hard drive in your Time Capsule, enter your password, and do a backup from there. It might work, and it might take a while, but it should go. As for clogging the hard drive, I can't say. Depends how much stuff you have, and the hard drive's capacity.  As for moving syncing from your iMac to your macbook pro, should be the same. Your phone uses iTunes to sync and so that data should be in the cloud. You can move your iTunes Library to your new Macbook pro
    you should be able to sync your phone on your new MacBook Pro. Don't know if you can move the older backups yet-maybe try someone else, anyways,
    This handy article from Apple explains how
    How to move your iTunes library to a new computer - Apple Support''
    don't forget to de-authorize your iMac if you don't want to play purchased stuff there
    and re-authorize your new macBook Pro
    time machine is an application, and should be found in the Applications folder. it is built in to OS X, so there is nothing else to buy. double click on it, get it going, choose the Hard drive in your Time capsule/Airport as your backup Time Machine  and go for it.  You should see a circle with an arrow on the top right hand of your screen (the Desktop), next to the bluetooth icon, and just after the wifi and eject key (looks sorta like a clock face). This will do automatic backups  of your stuff.

  • How to create a New Tranport Request for changed  Extract structure

    How to create a New Tranport Request for changed  Extract structure ?
    Hi Experts,
    I have a FI AP Generic Datasource containing extract structure with appended fields.
    It has already been activated and transported to Testing System.
    Now, I am to create a new transport request for this DataSource and Extract structure.
    I do not want to delete and recreate the Generic Datasource.
    I am trying to look at the options in the extract structure top menu from where I can create a new Tranport Request.
    Please let me know the steps
    URGENT

    Hi Dev,
    Once you send the transport request for any data source from Dev to Testing you wont find that again in your Dev (I mean the TR). So, when you change anything for this data source or view now in Dev and try to save it, it will ask for a new transport request and here you can mention a new one starting from View then activate it and go to RSO2 regenerate it and use the same transport request for this too. When you transport this TR to Testing Environment the data source will automatically get changed.
    Hope it helps...

  • How to create a new variant and a job sheduled to use it for the ......

    How to create a new variant and a job sheduled to use it for the exisisting programs

    Hi
    1. The ALV Grid Control is a tool with which you can output non-hierarchical lists in a
    standardized format. The list data is displayed as a table on the screen.
    The ALV Grid Control offers a range of interactive standard list functions that users need
    frequently (find, sort, filter, calculate totals and subtotals, print, print preview, send list,
    export list (in different formats), and so on. These functions are implemented in the
    proxy object class. You as the programmer have the possibility to turn off functions not
    needed. In most cases the implementations of the standard functions provided by the
    control are sufficient. However, if required, you can adjust these implementations to
    meet application-specific needs.
    You can add self-defined functions to the toolbar, if necessary.
    The ALV Grid Control allows users to adjust the layout of lists to meet their individual
    requirements (for example, they can swap columns, hide columns, set filters for the
    data to be displayed, calculate totals, and so on). The settings (list customizing) made
    by a specific user are called a display variant. Display variants can be saved on a userspecific
    or on a global basis. If such display variants exist for a list, they can be offered
    to the user for selection. If a display variant is set as the default variant, the associated
    list is always displayed based on the settings of this variant.
    2. REUSE_ALV_LIST_DISPLAY
    REUSE_ALV_GRID_DISPLAY
    REUSE_ALV_FIELDCATALOG_MERGE
    REUSE_ALV_COMMENTARY_WRITE
    3. Use of Field Catalog is to determines the technical properties & add formating information of the column.
    6. all the definition of internal table, structure, constants are declared in a type-pool called SLIS.
    7.fieldcat-fieldname
    fieldcat-ref_fieldname
    fieldcat-tabname
    fieldcat-seltext_m
    5. Form user_command using r_ucomm like sy-ucomm rs_selfield type slis_selfield.
    Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length.
    In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output.
    The report output can contain up to 90 columns in the display with the wide array of display options.
    <b>The commonly used ALV functions used for this purpose are;</b>
    1. REUSE_ALV_VARIANT_DEFAULT_GET
    2. REUSE_ALV_VARIANT_F4
    3. REUSE_ALV_VARIANT_EXISTENCE
    4. REUSE_ALV_EVENTS_GET
    5. REUSE_ALV_COMMENTARY_WRITE
    6. REUSE_ALV_FIELDCATALOG_MERGE
    7. REUSE_ALV_LIST_DISPLAY
    8. REUSE_ALV_GRID_DISPLAY
    9. REUSE_ALV_POPUP_TO_SELECT
    Purpose of the above Functions are differ not all the functions are required in all the ALV Report.
    But either no.7 or No.8 is there in the Program.
    <b>
    How you call this function in your report?</b>
    After completion of all the data fetching from the database and append this data into an Internal Table. say I_ITAB.
    Then use follwing function module.
    CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
    I_CALLBACK_PROGRAM = 'Prog.name'
    I_STRUCTURE_NAME = 'I_ITAB'
    I_DEFAULT = 'X'
    I_SAVE = 'A'
    TABLES
    T_OUTTAB = I_ITAB.
    IF SY-SUBRC <> 0.
    WRITE: 'SY-SUBRC: ', SY-SUBRC .
    ENDIF.
    ENDFORM. " GET_FINAL_DATA
    The object F_IT_ALV has a field, the activity ACTVT, which can
    contain four permitted values: 01, 02, 03 and 70. Each of the
    activities 01, 02 and 70 controls the availability of particular
    functions (in the menu and the toolbar) of the ALV line item list:
    a) 01: "Settings -> Display variant -> Save..."
    b) 02: "Settings -> Display variant -> Current..." and
    "Settings -> Display variant -> Current header rows "
    c) 70: "Settings -> Display variant -> Administration..."
    Activity 03 corresponds to the minimum authorization, which is the
    most restricted one: The user can only select layouts which have
    been configured already. In particular, all of the other functions
    named above are inactive with activity 03.
    Now if you want to permit a user to change the column selection and
    the headers as well as to save the layout thus created, for example,
    but if you do not want to permit the user to administrate the
    layouts, you grant him or her the authorization for activities 01
    and 02.

    I have done it follow the same process as for business process objects. But when i try to test it in BOBT, there is no records under "FIELD_CHANGE_WITH_FILTER". It seems the change hasn't been recorded.
    If the way I did to create change document for dependent object is correct, please also kindly advise the possibilities for why there is no record during testing.
    thanks in advance.

    I also have some doubts about the business object.In this case,one abstract BO hase a subnode wihich is root extended.I added the change document for this node under the category "root_extended" and then tested the function in BOBT.I got some error message "can't find the root key".Shall i redefine the method /BOFU/IF_CDO_CREATION~IS_CDO_CREATION_ACTIVE so as to solve the problem?

  • How to create an user input variable for customer exit variable? - BW3.5

    Hi Guru,
    I have a requirement for the selection period of my reports. There are 3 possible reporting periods which should be user selectable:
    1. Month: Current reporting month
    2. Fiscal Year to Date
    3. Project Year to Date
    Here I need 2 variable to do these, 1 customer exit and 1 user input variable. I have created a variable customer exit to calculate all these requirement. But can any1 tell on how to create the user input variable for my customer exit? I need a user input variable with drop down list like below.
    01-Current month
    02- Fiscal Year to Date
    03-Project Year to Date
    I have create a new master data for this variable, but it's not working. What I need now is a standalone master data which do not need to link to any exiting records. Can any1 tell me how to create this?

    Just go to the definition of the variable for which you have created a customer exit. There you will find a check box for "Ready for Input". Just tick that checkbox and the variable will be available as a selection variable in the reports selection screen.
