Hi,

If it is in the presentation server, Check out the class CL_GUI_FRONTEND_SERVICES. There is a method for checking the existence of the file.

If its presentation server use cl_gui_frontend_services=>file_exist

if application server then use DX_FILE_EXISTENCE_CHECK or just use a open dataset statement and check the value of sy-subrc.

This function module can be used for both servers.



parameters:  p_file(128) .

at selection-screen on p_file.
  perform check_file_exist using p_file sy-subrc.
  if sy-subrc ne 0.
    message e000 with 'File does not exist or Path+Filename > 128 chars'.
  endif.
*&---------------------------------------------------------------------*
*&      Form  CHECK_FILE_EXIST
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
*      -->P_SY_SUBRC  text
*----------------------------------------------------------------------*
form check_file_exist  using  p_file p_subrc.
  data: l_exist(1).

  call function 'DX_FILE_EXISTENCE_CHECK'
    exporting
      filename    = p_file
      pc          = 'X'  "if space then check is made in application server else in presentation server
    importing
      file_exists = l_exist.

  if l_exist ne 'X'.
    p_subrc = 8.
  endif.

endform.                    " CHECK_FILE_EXIST
