Hi,
Please see the below code .
Function module u2018DOWNLOADu2019
      CALL FUNCTION 'DOWNLOAD'
        EXPORTING
          filename = p_file
          filetype = 'WK1'
        TABLES
          data_tab = i_table.
would be replaced with:
data: gd_file type string.
DATA: ld_filename TYPE string,
      ld_path TYPE string,
      ld_fullpath TYPE string,
      ld_result TYPE i.
types: t_uctable like line of i_table.
data:  it_uctable type standard table of t_uctable.
  gd_file = p_file.
  shift gd_file RIGHT DELETING TRAILING '\'.
  shift gd_file RIGHT DELETING TRAILING '/'.
  shift gd_file left DELETING LEADING space.
  CALL METHOD cl_gui_frontend_services=>file_save_dialog
    EXPORTING
      DEFAULT_EXTENSION = 'WK1'
      default_file_name = gd_file
      INITIAL_DIRECTORY = gd_file
    CHANGING
      filename          = ld_filename
      path              = ld_path
      fullpath          = ld_fullpath
      user_action       = ld_result.
  check ld_result eq 0.
  gd_file = ld_fullpath.
  gd_file = p_file.
  it_uctable[] = i_table[].
  CALL METHOD cl_gui_frontend_services=>gui_download
  EXPORTING
    filename = gd_file
