Eventing on Graphics using ABAP Webdynpro is it Possible -EHP5

Hi,
I have below graphic output requirement..
On X-axis i will have fixed columns.. and I should have an option to  DRAG and DROP contents which should be like Blocks  from 1 column to other column.. which eventually should update database..Is it possible technically ? I know we can do drag drop whole column in ALV from EHp2 but this is some strange requirement for me..How do we handle this?
EMP3
EMP1                 EMP2                EMP4        
A                     B                   C                   D
FYI..We are SAP ramp up customers for EHP 5.0
Should we use
IGS( Internet Graphics Server) with Business graphic? Can we handle eventing?
Adobe Flex? If so do we need any extras for Client machines like flash? How complex would it be?
ALV Display as Graphic? As far as i know this is just display

NB - the "data" that is returned by these classes is the data as defined in an adobe form - it doesn't return the content of non-form PDF documents.
The PDF must be an interactive form ( although that doesn't restrict you to using the SAP process for creating the form is my understanding - but I could be wrong. )
Edit - I was wrong! ONLY PDF documents that have been created by the ADS can have data extracted using these classes. So unless you are using Adobe interactive forms - then you will get no value from this functionality - and if you're using AIF then you're probably just use the standard UI element

  • How to create a view to display Multiple lines of Text using ABAP WebDynpro

    Hi,
    I need to create a static view page in ABAP WebDynpro that displays Static text data in multiple paragraphs. I tried to use textview, formatted text, text edit controls by binding the textcontrol to a text object that is created in so10, but the output I am getting is only one line and the character count is limited to 60 to 65 characters.

  • How to Raise Event in BW using ABAP program

    Hi BW Experts,
    Can anyone tell how to raise event in BW using a ABAP program.
    Program should ask for the event to be raised and destination server.
    Edited by: Arun Purohit on May 14, 2008 11:04 AM

    Hi Arun,
    By Using BP_EVENT_RAISE function module you can raise an event.Create an ABAP program and call the function module BP_EVENT_RAISE and create a avariant to specify the event to be raised. Schedule this ABAP code. Go to the start process type and set the schedule to "after event" and mention the event name that you created. Also, I think now you can mention the time as well and you can also schedule for periodic scheduling.
    T Code : SM62 --> To Create an Event.
    T Code : SE38 --> To Create an ABAP Program
    Use Function Module : BP_EVENT_RAISE to raise an event.

  • How to display HTML files using ABAP Webdynpro?

    Hi,
    I have a html index file and a bunch of other files accessed by the index file  in a specific directory on the SAP server. I'd like to display the index file via ABAP webdynpro and allow the users to click on what they need to see. How can I achieve this using utilizing the ABAP webdynpro technology ?
    Thanks!

    Hi Thomas,
    Thanks for taking the time to answer my question.
    I have the main html file and all other files needed by the main file in one directory on the application layer of SAP. I'd like to provide the user with a link, by clicking on which they should be able to get to the main html file using the browser. This is just a standalone application.
    I can try the approach using BSPs, however, I'm new to that area. Could you point me in the right direction to get started?

  • Error Handling in tables using ABap Webdynpro

    Hi All,
    I am new to this ABAP webdynpro programming. I have a small question. I am using a table control in one of my iview. I need to check some validations on some columns of this table. Let's say I have a table with 3 columns A,B and C. 
    Case 1 : Whenever any user enters values in C which is greater than A i want to raise an error message saying "The Value is greater than A". The user shouldn't be allowed to enter anyother inputs before correcting the same.
    OR
    Case 2: If the user enters 10 rows in the table and the 5th row contains the error. How can i highlight that row or field which contains the error.
    Your inputs will be valuable to me.
    Regards,

    Hi,
    Get the elements of the node for which you table is bound.
    Loop through the context element set.
    get the record for that context attribute and check the column A and column B value and throw
    the error using the report_error_element_message when there is error.
    Check this sample code -
      DATA:
        lt_attr_list type STRING_TABLE,
        ls_attr_list type string.
      ls_attr_list = column name.
      append ls_attr_list to lt_attr_list.

  • Accessing Business Graphics using the WebDynpro API

    I would like to access Business Graphics created with IGS using the WebDynpro Business Graphics API.
    I have no problem displaying the graphic in WebDynpro UI, but i have no idea how to access the binary data of the graphic to work with it outside of WebDynpro UI (in fact i want to embed it into a PDF form).
    Is there any possibility to do this using the WebDynpro API?
    I would appreciate your help!

    Thanks, but this al clear to me. I am able to display business graphics on web without problem (I have dynamic Business Graphic in my WebDynpro User Interface).
    The Problem is, that i want to make further processing with the graphic. Therefore i need to access the binary data of the graphic.
    Do you know if there is any possibility to get the binary data of the bmp - image generated by IGS into a byte array?

  • Excel download with multiple worksheets using ABAP webdynpro

    Content of Internal table should to downloaded  to an excel sheet with multiple worksheet.

    Excel doesn't support multiple worksheets with the text tab delimited or any of the other plain text formats.  So if you need multiple worksheets those approaches are out.  Multiple worksheets would only work with the Excel native format or the XML based format.  From ABAP the best approach would be to create the XML Excel format.  Search the forms and wiki has there has been tons of discussion in the mast on the XML Excel format.

  • Smartform & ABAP Webdynpro & Internal table

    Hi Expert,
    I am able to open the smartfrom by using ABAP Webdynpro.
    But when I try to add the table under "Global Settings -> From Interface -> Table"
    Paramemter Name       Type Assignment    Associated Type
    I_ZSG_PAY_DATA     Like                          ZSG_PAY_DATA
    It works fine when I test it in t-code SMARTFORMS. But when I use the same ABAP Webdynpro program to open this smartform, the error appear.
    "Calling Parameter incorrect"
    Could you please let me know how to fix it?
    Thanks a lot,
    WF

    Hi William,
    If you have a working smartform then you should be able to display it in WD by passign its XSTRING to the PDFSOURCE of it.
    Just check that where you have written the code to get the XSTRING of smartform in WD. You might have modified the smartform interface and forgot to call the revised FM generated after the smartform was changed in WD.
    Just re-write the entire code to generate XSTRING for smartform and see if it works or not.
    You can also try to put a break point in the code and see where exactly it is failing i.e. whether it is to do with calling smartform or converting it or WD related.
    Thanks,
    Abhishek
