  • Accessing ABAP Functions in Web Dynpro Java in CE7.1

    Hi,
    I have a CE7.1 SP5 system installed and no access to an SLD. How can I use BAPIS  of an R3 backend system within a Web Dynpro application? Adaptive RFC only works with an SLD, right?

  • Accessing ABAP Functions in Web Dynpro

    Hi all,
    for testing reasons I would like to implement a simple Web Dynpro Application which access APAP functions (or BAPIs) on a remote SAP backend system. The problem is that I dont have a SAP backend system
    There is a tutorial :
    <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/355b9c90-0201-0010-d2a8-89fece426526">https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/355b9c90-0201-0010-d2a8-89fece426526</a>
    which states some prerequisites.
    My question:
    Is it possible to comply to all these prerequisites by installing NetWeaver Preview and minisap as remote SAP backend system ? Where can I get minisap ?
    I'm quite new to SAP so I'm al little unsure which part belongs where.
    Maybe someone can give me a hint.

  • How call key Function in WEB Dynpro Java?

    Hi,
    Somebody know how to call key Function(F1, F2, ... F12) in WEB Dynpro Java to launch and Event?
    Thanks in advance.

    Hi,
    You can WDHotKey property to define the different keyboard shortcuts to enable the user to trigger events with key combinations.
    When the user presses the key board shortcut defined as the hotkey then onAction event is triggered.
    The keys F2, F3, F4, F5, F6, F7, F8 and F9 are not supported, they call predefined functions provided by the Web Dynpro Framework.
    The complete list of supported shortcuts is here:

    There are various spell checker webservices you could use (Google, Yahoo, etc) which upon submit of your form will be called.
    However, keep in mind you won't have fancy inline-edit-and-replace functionality, but you either you could just present a list with results and have the user make the corrections himself, or you could correct all the findings at once without user interaction

  • How to configure SSO for web dynpro ABAP (not web dynpro Java)

    Hi Experts,
        I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
    1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
    2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
         procedure"
       Then deleted all logon procedure other than "SSO Authentication" and saved.
    3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
         signal).
    4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
    After all this settings I opened a browser enter above URL and hit enter but there is an error
    There is no login page. It directly showed this error page. No cookies is saving.
    Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
    How to set the for single sign-on?
    Thanks in Advance

  • Error - Creating a Web Dynpro Application Accessing ABAP Functions

    Dear All,
    we are trying to implement a web dynpro application with accessing ABAP functions.
    Previous tasks:
    -     insert the ABAP system into the SLD from the NWDI System (Transaction RZ70; the ABAP system is correctly insert into the SLD => technical systems)
    -     equipped the JCO connections with the web dynpro content manager (ping and test = OK)

    There two different URLs in use.
    Start via NWDS:
    http://frasapp562:50000/webdynpro/dispatcher/J08_Flugdat_Daventdcflight~xxx.com/FlightListApp
    Start via web dynpro content manager:
    http://frasapp562:50000/webdynpro/dispatcher/xxx.com/aventdc~flight/FlightListApp
    For test purposes, we started the BAPI (BAPI_Flight_Getlist) on the ABAP system directly. It works.
    Any ideas about the system behaviours (different URLs and missing functionality)?

  • Web Dynpro Java Internationalization and backend ABAP function modules

    Friends,
    I have a requirement where I want my Web Dynpro Java application to support BRAZIL and CHINESE.
    I have been through the sample programs and tutorials and I understand how to support my application in these 2 languages. The challenge I am facing is how to communicate the language to the backend code (ABAP function modules) so that the function modules can written language specific error messages and texts.
    I searched SDN but could not find anything. Your help is appreciated.

    Prashant,
    When you are configuring JCo connection in WebDynpro Content Administrator, just left language settings blank for metadata connection (you may do the same for data connection). Now WD will supply language of currently logged-in user when obtaining connection settings from system landscape and you'll get necessary functionality.
    By default locale of user determined by parameter sap-locale (sap-locale=de_DE for example), settings of user's browser and lastly preferences of user stored in UME.
    Btw, BRAZIL (or Portugees for this matter) is not fully supported language by SAP, so R/3 side may be not  translated or partly translated.

    Hi,
    <b>Web Dynpro for ABAP:</b>
    Web Dynpro for ABAP or Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web applications in the ABAP environment. It consists of a runtime environment and a graphical development environment with special Web Dynpro tools that are integrated in the ABAP Workbench (SE80).
      The use of declarative and graphical tools significantly reduces the implementation effort
    1)    Web Dynpro supports a structured design process
    2)      Strict separation between layout and business data
    3)     Reuse and better maintainability by using components
    4)     Automatic operation of the Web Dynpro application using the keyboard
    5)     User interface accessibility is supported
    6)     Full integration in the reliable ABAP development environment

    <b>Web Dynpro for Java:</b>
    Web Dynpro is a client-independent programming model of the SAP NetWeaver technology platform for developing user interfaces for professional business applications. It is based on the model view controller paradim which ensures that the business logic is separated from the presentation logic. This architecture is visible in the Web Dynpro perspective of the SAP NetWeaver Developer Studio (NWDS).
    Web Dynpro helps you with the development of Web applications by:
    1)       Ensuring platform-independence with the meta model approach
    2)       Minimizing the implementation effort through declarative programming
    3)      Supporting a structured design process by applying the model view controller paradigm
    4)        Providing reuse and better maintainability by using components
    5)       Providing graphical support with tools in the Web Dynpro perspective
    6)       Providing the SAP NetWeaver Java Development Infrastructure (NWDI) which supports team work with different services such as source code versioning and the Central Build Service.
