Getting the Filter line by default in ALV.

Question

Hi friends,
        There is a requirement for me, wherein, i need to provide a default filter line when the page loads initially. Generally we get a filter line, when we filter on any of the fields available, but in my case, without filtering on any of the fields, i should get the filter line. Is that possible in real?
If yes, kindly provide me the appropriate code.
Thanks & Regards,
Akshay

Hi,
Please try the below code.you can find more solution in sdn.
This displays both the filter line and the FILTER option(rightside top)
DATA:
lv_value type ref to cl_salv_wd_config_table.
  DATA: lt_fields TYPE salv_wd_t_field_ref,
        ls_fields TYPE salv_wd_s_field_ref,
        lr_field TYPE REF TO cl_salv_wd_field,
        lr_filter TYPE REF TO  cl_salv_wd_filter_rule.
  CALL METHOD lv_value->if_salv_wd_field_settings~get_fields
    RECEIVING
      value = lt_fields.
  LOOP AT lt_fields INTO ls_fields.
    lr_field = ls_fields-r_field.
    CASE ls_fields-fieldname.
      WHEN 'VBELN'.
        CALL METHOD  lr_field->if_salv_wd_filter~create_filter_rule
          EXPORTING
   included   = 'X'
      operator   = 'NE'
            low_value  = space            
   high_value =
          RECEIVING
            value      = lr_filter.
      WHEN 'ERDAT'.
      WHEN 'ERZET'.
      WHEN 'ERNAM'.
      WHEN 'ANGDT'.
    ENDCASE.
  ENDLOOP.
