Hi,
    data:
      ls_map    type if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping,
      lt_inmap  type if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping_tab,
      lt_outmap type if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping_tab.
  ls_map-context_attr = 'SECTION'. (config field name)
  ls_map-f4_attr      = 'SECTION'. (searchhelp field name)
  append ls_map to: lt_inmap, lt_outmap.
  ls_map-context_attr = 'SUBSECTION'.
  ls_map-f4_attr      = 'SUBSECTION'.
  append ls_map to: lt_outmap.
  create object rv_valuehelp_descriptor type cl_bsp_wd_valuehelp_f4descr
    exporting
      iv_help_id = '(ur search help name (it should contain section and subsection fields))'
      iv_help_id_kind   = if_bsp_wd_valuehelp_f4descr=>HELP_ID_KIND_NAME
      iv_input_mapping  = lt_inmap
      iv_output_mapping = lt_outmap.
in the above logic if u select section value automatically subsection value wil be display.
