  • How to export data from webdynpro to Excel and start a Excel macro

    Hello All
    I want to export data displayed in the Web dynpro ALV into Excel. I have tried the ALV export function but my problem with it is when it does export to excel the data loses formatting and I have long text in columns which display with wrapping in ALV but when exported to excel it loses formatting.
    So I want to define a custom button and when user presses on this button the excel export is called with a macro. Can you kindly share ideas how I can do this from a webdynpro.
    Thanks
    Karen

    Hi friends!
    I have followed the following:
    http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=(J2EE3417300)ID1487994050DB10407586481486749551End?blog=/pub/wlg/5522
    ...in order to create standard ALV with Export to Excel.
    However what is exported into excel is awful. It does not contain my data in nice columns... Instead it shows a lot of meta-data.
    Please let me know what to do to kick the standard Export button in the correct direction.. that is...to have my nice table in same way in Excel, because that is my intention with "Export to excel"

  • How to get the complete data from Webdynpro using a RFC

    hi guys,
    A form is created in the webdynpro, when that pdf form is called the user have to provide the key field ie the employee number in the form and then when he press the 'go' button a rfc is called and it gives all the details of the employee in the form. Then the user have to input some fields in the form and he have press the submit button. My problem is here, when the user is going to press the submit button that form will be converted to a stream (binary) of data and it is sent to one of the import parameter used in the RFC.
    I have created a RFC and created a import parameter of data type XSTRING, since i want to see what exactly R3 is receiving from web dynpro i am writing this contant in the sever as a text file. When i saw that text file i cant see the complete data.
    And when i searched in R3 the capacity of xstring is 1024 CHAR, so i dont know how to capture the entire data from webdynpro into my R3.
    I give the code what i worte please tell me am i missing anything in my code, or is there any data type which can hold more than 500kb of data which is coming from webdynpro.

    You have to convert your long string to a table of shorter strings.
    There may be other ways, but one possibility is to use a loop to process you string.
    while (there is something left)
       put the next e.g. 1024 characters in a new row of your table
    endwhile
    If you need to reconstruct your string from the table, don't use simple concatenation since it will remove blanks at the end of lines. Believe me (from experience) sooner or later this will happen.
    Instead you need to either set the subsections of your long string, or insert from the end of your table and keep shifting the contents (probably less efficient) right

  • Exporting Data from WebDynpro to a Word-file

    Hello,
    I'm looking for a way to export data from a WebDynpro to a MS Word-file. I have already a template of the word-document, so the data should be transfered to a specific area of the file.
    I already checked the Jakarta project, but the Word sub-project seems not mature yet. I also read about the possibility to do this using XML. But because I'm not familiar with XML, I don't know if it is possible to fill an already existing file. Are there some free APIs which can be used for this purpose?
    Thanks for any hint!

    Any help
    Regards

    Please refer the example in this link which deals with Oracle date format.
    You can finnd a command DECODE which is used for date formats. If you have a look at whole theory then you will get an idea.

  • How to export data from Elimination Value dimension member by HAL HFM adapter?

    Good day!<BR><BR>Is it possible to export HFM 4.0.5 data with HAL from the <Elimination> Value dimension member?<BR><BR>In 3.* versions it wasn't and there is Known Issue in the "HFM 3.* Adapter Read Me" file: "The Hyperion Financial Management Adapter exports data using the <entity currency> Value dimension member. The documentation erroneously states that there is a port available for the Value dimension"<BR>But there is not such point in the same file for HFM 4.0.5 AND there is Value port in the HFM 4.0.5. Adapter.<BR><BR>Thanks!<BR><BR>Regards,<BR>Georgy<BR>

    In the first approch, try to change the exporting parameter type REF TO DATA.
    Try like:
    CLASS lcl_test DEFINITION.
      PUBLIC SECTION.
        DATA: t_mara TYPE HASHED TABLE OF mara WITH UNIQUE KEY matnr.
        METHODS:
          constructor,
          get
            IMPORTING
              if_matnr TYPE matnr
            EXPORTING
              ea_mara  TYPE REF TO data.
    ENDCLASS.                    "lcl_test DEFINITION
    START-OF-SELECTION.
      DATA: lo_test TYPE REF TO lcl_test,
            lr_data TYPE REF TO data.
      FIELD-SYMBOLS: <fa_mara> TYPE ANY,
                     <f_field> TYPE ANY.
      CREATE OBJECT lo_test.
      lo_test->get(
        EXPORTING
          if_matnr = '000000000077000000'   " << Replace Your Material
        IMPORTING
          ea_mara  = lr_data ).
      ASSIGN lr_data->* TO <fa_mara>.
      ASSIGN COMPONENT 'ERSDA' OF STRUCTURE <fa_mara> TO <f_field>.
      <f_field> = space.
      WRITE: 'Done'.
    CLASS lcl_test IMPLEMENTATION.
      METHOD constructor.
        SELECT * INTO TABLE t_mara
               FROM mara
               UP TO 10 ROWS.
      ENDMETHOD.                    "constructor
      METHOD get.
        FIELD-SYMBOLS: <lfs_mara> LIKE LINE OF me->t_mara.
        READ TABLE me->t_mara ASSIGNING <lfs_mara> WITH KEY matnr = if_matnr.
        GET REFERENCE OF <lfs_mara> INTO ea_mara.
