Hi,

Please make use of this CLASS "CL_GUI_FRONTEND_SERVICES" there you can make use of

the methods

"FILE_EXIST" for checking the file existence

"DIRECTORY_EXIST" for checking the directory existence.

Hope this will help you.

Regards,

Smart Varghese

Hi,

simply try an OPEN DATASET <fn> FOR INPUT IN TETX MODE (for the application) or call function GUI_UPLOAD (for the presentation) and check the sy-subrc .

If it's 4, there is an error in filename or path.

I know that is not the best way, but is the quick one (expecially for application server files).

Best Regards

Andrea

HI,

Use this method to check the existence of the file on the presentation server..

CL_GUI_FRONTEND_SERVICES->FILE_EXIST

CALL METHOD cl_gui_frontend_services=>file_exist
    EXPORTING
      file                 = l_file
    RECEIVING
      result               = l_result
    EXCEPTIONS
      cntl_error           = 1
      error_no_gui         = 2
      wrong_parameter      = 3
      not_supported_by_gui = 4
      OTHERS               = 5.
  IF l_result NE on.
    CONCATENATE 'File not found:' l_program INTO msgtrc
                SEPARATED BY space.        
 ENDIF.
