ALV Web Dynpro for ABAP enable/disable single row

hi all,
is it possible to change the layout of one single row or cell in a alv (component SALV_WD_TABLE) web dynpro for abap?
i managed to get columns to be editable using the tutorial "Editing ALV in Web Dynpro for ABAP".
but it is not described how to change a single row or cell in this tutorial. also the example programs i found do not get into this subject.
did i miss something?
thanks in advance

Hi,
I think you cannot set the focus to the particular cell.
I think you can  loop at that row of that table and set the the cell design to apply some color to differentiate that way rather than focusing so that user can know that he has to do something in that cell.
check out this example salv_wd_test_table_focus

Lekha.

  • Events on ALV in Web Dynpro for ABAP

    Hi
    On an ALV GRID in ABAP one can use the event handle_data_changed that is activated immediately at the time data is changed.
    Is there a similar event in ALV in Web Dynpro for ABAP?
    How would I know if any data was changed in an ALV grid in WDA?
    Regards

    Hi,
    To trigger the DATA_CHECK event on pressing enter, you need to use the set_data_check method. Use the following code:
    l_alv_model->if_salv_wd_table_settings~set_data_check( IF_SALV_WD_C_TABLE_SETTINGS=>DATA_CHECK_ON_CELL_EVENT ).
    Now you can define the data check event handler and it will get triggered when you change something and press enter, or even if you click on another cell. The DATA_CHECK attribute will by default be set to be trigger only on clicking the 'check' button. This will change it.

  • Direct link to Web Dynpro for ABAP

    Hey everyone,
    I created a web dynpro    for ABAP    application that will list out all the work items for the purchase requisition approval through workflow. I want to be able to have our higher ups be able to access this through our portal. I created an iView    that works and calls the application just fine.  What I want to do now is provide a link in an email to these people so they will be able to log into the portal and go directly to the application (just the application not portal wrapper around it at all) and only the application.  I can't provide a directly link to the WDA app since, I think, it would be to the ECC server and not the portal one.
    I have tried Quick Links but that isn't what I want.
    I did try to put a pcd location link
    http://<server>:<port>/irj/servlet/prt/portal/prtroot/<pcd location>
    but I get an internal error because it's trying to do an anonymous login and I want the login screen to show up first.
    HELP!!!!!
    Thanks,
    Archie

    The PCD path of the portal object is the Navigation target.
    http:/myServer:50000/irj/portal?NavigationTarget=ROLES://portal_content/myFolder/myRole
    This can be hashed and shortened to form the Short URL as shown below
    http:/myServer:50000/irj/portal?NavigationTarget=navurl://b3d6d9ebac16a46574d62757803b05d4
    Short URL can be enabled and disabled depending upon the requirements.
    Check the links below for detail description to enable short URL:
    http://help.sap.com/saphelp_nw70ehp2/helpdata/en/43/014421d21d6fade10000000a11466f/frameset.htm
    http://help.sap.com/saphelp_nw70ehp2/helpdata/en/49/330b66fd695aa8e10000000a42189d/frameset.htm
    NavigationTarget generally shows all the portal roles with the specific object highlighted.
    In the sense it takes you to that Object with the portal header and TLN.
    If your requirement is not to show header and TLN,then try adding &NavMode=3 to the NavigationTarget url you are using as below
    http://<server>.<port>/irj/portal?NavigationTarget=ROLES://<PCD path of object>&NavMode=3
    I( made some testes here, and works fine for worksets and roles.
    Hope it Helps.

    Hi,
    Go to internet explorer -> tools -> internet options -> Advanced
    There locate the check box "Enable memory protection to help migrate online attacks" and uncheck it.
    Let me know if that works.

  • What SAP component support Flash Island in Web Dynpro for ABAP?

    Hi  Experts,
    What SAP component support Flash Island in Web Dynpro for ABAP? I don't find flash island control to place it in the view.
    Thanks,
    Duy

    FlashIsland is a native UI element like table or image - not a reusable component like ALV.  What release level is your system?  FlashIsland is only available on NetWeaver 7.0 Enhancement Package 1 and higher.
    Also the FlashIsland UI element must be a root UI element. Therefore it has be created in its own view.  Right mouse click on the ROOTUIELMENT in the UI element hierarchy and choose Swap UI Element Definition.

  • Web DynPro for ABAP Basics

    Hello Seniors,
    I am new to Web DynPro for ABAP. Could you please give me some information or send some basic documents for Web DynPro for ABAP. Please send some basic scenarios also.
    Thank you,
    Chaitanya.C.N

    Hi Chaitanya,
    Here is some information about Webdynpro for ABAP.
    1) This is basic Info of WD ABAP
    As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
    The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
    Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
    2 ) I can give you links that can help you a lot.
    First of all start doing SAP SDN tutorials .
    Create some compenents with BAPI , Component usage and ALV .

    Try to Download demo tutorials from SDN library & Try to search WebDynpro ABAP WebLogs .
    Also, SAP has provided you with ample demo example of WD ABAP already bundled with SAP . Just Try out Components starting with WDR . I can tell you few like WDR_TEST_EVENTS ( It shows how every UI elments to use )
    See packages like SWDP_DEMO , SALV_WD_DEMO
    there are many more .
    We can call BAPI through a service call in web dynpro application. Thus automatically backgroud code for BAPI execution will be generated.
    To start with Web dynpro ABAP you can try following tutorial:

  • Floor Plan Manager Technique in Web Dynpro for ABAP

    Hi Experts,
    Road map technique and Floor Plan Manager Technique, both are same or different.
    I need to develop a web dynpro application based on Floor Plan Manager Technique. can I develop this application in WebDynpro for ABAP. If so please help me how to use Floor Plan Manager Technique in Web Dynpro for ABAP.
    I don't have knowledge in java, so i cann't develop this application in web dypro for java.
    Please help me.
    Thanks & Regards
    Sridhar

    >Road map technique and Floor Plan Manager Technique, both are same or different.
    They are different. The FloorPlan Manager is a tool for constructing WD applications with a similar layout and user interface.  There are two different floor plans currently - the OIF - Object Instance Floorplan and the GAF - Guided Activity Floorplan.  The OIF is for the editing of a single business object. It allows for things like the nesting of header and item details.  The GAF, on the other hand, uses a road map to walk you through an activity - much like a Guided Procedure.  The FloorPlan Manager is very powerful because it can be configured using component and application configuration - allowing you to plug in different UI Building Blocks (UIBB) as Web Dynpro Components or Views.  You can change the roadmap, for instance, adding a new step by just chaning this configuration and not having to touch the code.  Consistency between applications is also a major stregth of the FloorPlan Manager. 
    The Road Map is just a UI element in WD.  It can be used to create your own custom applications.
    >can I develop this application in WebDynpro for ABAP
    Sure.  The Floorplan manager has been available for WDA since SPS13.  Have a look at the packages APB_FPM_DEMO and ABP_FPM_TEST for examples of how to build components designed for the FloorPlan Manager.
    Admittedly there aren't a whole lot of documents available on the subject yet. Some eLearning is being worked on now.  There are going to be some workshops at TechEd on the subject:
    https://wiki.sdn.sap.com/wiki/display/Community/BringitallTogetherwithFPM%28FloorplanManager%29forWebDynpro+ABAP
    The best thing to do right now is to study the demo applications SAP provides.

  • Call back-end report from Web Dynpro for ABAP

    Hi Experts,
    I have an web dynpro for abap application, I put it into an iView. I also have a report which have selection screen and ALV display in back-end. Now I would like to call the report from the web dynpro application and display it in the web.
    What steps need to be done to do it?
    Thanks,
    Anthony

    Anthony,
    you can create a custom transaction for your report "for example ZREPORT" and then create an IVIEW for ZREPORT.
    in your webdynpro you can create a button or link and in the action behind you can call OBN and pass the IVIEW parameters for the OBN call.
    OBN can be found in the webdynpro wizard tool.
    thanks!

  • N4S: Web Dynpro for ABAP layout editor not working

    Have problem in Layout editor in Web Dynpro for ABAP
    I have installed NW04S Testdrive on 64bit Linux and able to login.
    SE80 is working alright.
    Next I create a Web Dynpro Comp. / Intf. and create a component.
    I double click on the View name "V_Default" . The Layout editor opens on the right side. Change into Edit Mode.
    The "View Elements" panel on the left side of layout editor is missing. This is where we select the various elements like "Textview" etc.
    Even the right click on the "ROOTUIELEMENTCONTAINER" to insert elements using context menu does not work.
    In summary I am not able to add any element in WD4A Layout screen.
    Is there any special plugin required to be installed?
    How to solve this problem?

    you cannot develope Webdynpro for ABAP using ECC5
    This is available with netweaver 2004s (WAS7.0) for which ramp up is going on right now and the general availability is expected sometime around 1st quarter for 2006.

  • Import Data from Office Control (Web Dynpro for ABAP) into internal-Table

    Hello,
    I have a question concerning the Office Control UI-Eelement in Web Dynpro for ABAP:
    How can I import spreadsheet data from the Office Control into  a internal-table?
    I have an Excel-sheet (without any data) which is shown initially in the Office Control. First the empty Excel-Sheet will be loaded and in the second step data from an alvxml-transformation will be loaded into the Excel-sheet with the method 'activatexmlsource'. This works so far. When I change the loaded data in the Office Control and save it it will be stored as XLS-File. The problem is that I'm not able to use existing Upload-FM because every function module I tried uses GUI-functions and WebDynpro has no GUI-functionality. I always get the error that data from clipboard cannot be imported.
    So now the question is:
    How can I import changed data from the Office control into a internal-table staying in Web Dynpro application?
    Please give some advice, if you have some useful code or ideas.
    Thanks

    Hi,
    Once you save to desktop again you have made some changes to that file, this file you want to upload it right.
    Then in that case you need to use the FILEUPLOAD UI element right.
