Configure a web dynpro application!!!

Question

Hi Experts,
I am working on ESS-Travel and Expenses application. In that I have an ALV displayed on a POWL component. Here when we go to user settings after we right click on the ALV we get option to hide/show the columns of the ALV. What I need is to restrict the user to personalize these settings to show/hide columns in the ALV. Please suggest a solution.
Thanks and Regards,
Vaibhav Tiwari.

Have a look on this code which will hide 'export' and 'pdf' option from header of ALV. Doube click on if_salv_wd_std_functions on this interface and you will see all the function. Then just find out which you want to hide, get the method name from there and add the line in this code...and make as abap_false.
DATA: lr_cmp_usage           TYPE REF TO if_wd_component_usage.
  lr_cmp_usage = wd_this->wd_cpuse_cu_alv_search( ).
  IF lr_cmp_usage->has_active_component( ) IS INITIAL.
    lr_cmp_usage->create_component( ).
  ENDIF.
  DATA: lr_if_controller TYPE REF TO iwci_salv_wd_table,
        lr_config_model  TYPE REF TO cl_salv_wd_config_table.
  lr_if_controller = wd_this->wd_cpifc_cu_alv_search( ).
  lr_config_model = lr_if_controller->get_model( ).
  lr_config_model->if_salv_wd_std_functions~set_export_allowed( abap_false ).
  lr_config_model->if_salv_wd_std_functions~set_pdf_allowed( abap_false ).
Hope it works.
