the code seems to be correct....but where are you writing it?
put the code in the wddoinit method and it should work.
have a look at this article..

Changing the text and the order of columns in ALV for WebDynpro

Hello experts, im using ALV in WebDynpro, and i have this code:
lr_column = lo_value->if_salv_wd_column_settings~get_column( 'ZNC_MONTO_LIQ' ).
lr_column_header = lr_column->get_header( )
lr_column_header->set_text( 'IMPORTE' ).
but this code, doesn't change the title of the column.
the same happens when i put the visibility in "none" or when i change the position of the column
Anyone can tell why this is happening?
Thanks!

You can't set the text of the generated header directly. You have to first delete the standard header and create a new one. You can then override the header text.
l_column = l_table->if_salv_wd_column_settings~get_column( 'CREATED_AT' ).
l_column->delete_header( ).
l_header = l_column->create_header( ).
l_header->set_text( `Created At` ).

Creating ALV reports using OOP concept

After creating many reports i found out that 90% of the coding in a report is copy paste i.e. only 10% of coding effort is required which includes
    creating the custom data types and internal table variables ...
    populating the data
    creating screen,GUI status and GUI title
Just copy paste the below code and do as stated :
*ALV TEMPLATE
*create screen no. 2000
*change flow logic in screen if necessary
*create GUI status and GUI title
*change selection texts and text symbols*
REPORT Y_TEMPLATE_ALV.

Calling methods, creating instances, casting etc are not OOP. When you say you've developed an OO-report you think OO, refer to this blog to see what i mean - Global Data in ABAP OO Programs

Error when the time of create apllication in webdynpro abap

hi,
when i am trying to create apllication for webdynpro component it shows the error message like
'you are not authorized to use transaction sicf ' in the status bar . what is the problem and how can avoid this issue.

Hi Babu,
You are not authorized to use SICF tcode in development client. So try to create Webdynpro application in testing client where u have authorization for this tcode.
Because whenever you create a webdynpro application, Internet Communication Framework (ICF) services for that application has to be maintained.since you are not authorized to access SICF it fails to do the same.
For more information refer the below link

I hope this will help you.

How to restrict the no of rows to be displayes in ALV in webdynpro

Hi All,
Can any one suggest how to restrict the no of records to be displayed in the portal in the ALV through webdynpro ABAP.
Thanks & Regards,
Sreelatha Gullapalli.

HI,
If you want to change the Source (Design time) then you can do that via the alv configuration.
Something like this in the component SALV_WD_COLUMNS_UI
lr_available_model->if_salv_wd_table_settings~set_visible_row_count( lc_row_count ).

Yes, but it only has one generic Date column, no start date and end date. I can't use that twice in the prompt. Although I can specify it to be 'between', but I'm not sure I can pass values to both variables like that.
Currently I have used Campaign Start Date and Campaign End Date to enter values in calender format to the variables.

Is it possbile to create ALV Grid using Class & without using SE51

Is it possible to create a alv grid using Class, with out using the screen painter(SE51).

Hi Preethi,
It is possible to creat ALV grid using class, provided u have to create a custom control in the screen dialog.
Try with the foll code. This is an example for flight detail.
DATA: container TYPE REF TO cl_gui_custom_container,
      alv_con TYPE REF TO cl_gui_alv_grid.
data : it_sflight like table of wa with header line,
       g_fieldcat type lvc_t_fcat.
/* Paste the code the PBO
    CREATE OBJECT container
      EXPORTING
        container_name              = 'C_SPFLI'. "Specify the container name which u created in the dialog screen.
    CREATE OBJECT alv_con
      EXPORTING
        i_parent          = container.
/* Use the foll. to dislay the report
CALL METHOD cl_grid->set_table_for_first_display
        EXPORTING
         I_STRUCTURE_NAME              = 'SFLIGHT'
        CHANGING
          it_outtab                     = it_sflight[]
          IT_FIELDCATALOG               = g_fieldcat.
First create the container and then place the ALV in the container and for dislaying pass the necessary table.
Hope this will useful for u.
Get back if u r unable to do it.

Create ALV with to containers with the option to drag fields

HI All ,
I need to create ALV report that the report have containers that you can drag
some fields from one containers to the second one (if its not possible maybe to mark some fields and push on button and the marked fields will be shown on the second container ) there is sample that i can use
and can help me to do that ?
Regards
Alex

Hi Alex,
You can do that with OOP ALV.
You need to create two custom containers on the screen for displaying two layouts. Then with the help of ondrag, ondrop and ondropcomplete events you can drag a record from one layout to drop into another table.
Please refer report 'BCALV_TEST_GRID_DRAG_DROP' which has detailed description and explanation for each of the required events' definition and implementation.
Hope this helps.
Thanks.

Has anybody created Iview from "Webdynpro Java" component in CE7.1 ?

Hi All,
Has anyone created Iview from Webdynpro Java component in CE7.1.
Because the wizard that appears for creation of Iview has only "Webdynpro ABAP"
component.There is no option to create iview from "Webdynpro Java" component.
Althought in portal content--->Template folder i can see there is also
another template for "SAP Webdynpro iview" which i think is for the Java scenario.
But issue is, its not coming in the wizard.Can anyone tell me how to make it appear in the wizard ? It will be of great help to me.
Thanks and Regards
Ashis

Hi Ashis,
your deployed webdynpros are published under "web dynpro applications". just copy the webdynpro from there and paste it into the portal content section.
http://help.sap.com/saphelp_nwce10/helpdata/en/ce/e0d6f54ae641fc9566501cffaa8c6c/frameset.htm

Hierarchical sequential display in ALV for webdynpro ABAP

If you have any pointers for programming a Hierarchical Sequential report in Webdynpro alv that would be great. Any classes, methods etc I can use or , how I can do bindings to the context etc...
