path validation

[Former Member]

Hi,

I'm generating files in my program and dropping those files based on the path given in the selection screen. The user might choose a path on his system or shared drive or a path on the app. server.

I need to validate whether those paths, whether those paths exists or not. please let me know how to handle this situation.

Regards,

ravi.

Please try to use the DIRECTORY_EXIST method of the class CL_GUI_FRONTEND_SERVICES.

You can use this example.

report zrich_0001 .

type-pools: abap.

data: path type string.
data: result type abap_bool.

parameters: p_path type localfile default 'C:sap'.

at selection-screen .


path = p_path.

call method cl_gui_frontend_services=>directory_exist
  exporting
    directory            = path
  receiving
    result               = result
  EXCEPTIONS
    CNTL_ERROR           = 1
    ERROR_NO_GUI         = 2
    WRONG_PARAMETER      = 3
    NOT_SUPPORTED_BY_GUI = 4
    others               = 5
        .
if result = space.
  message e001(00) with 'Path/Directory does not exist'.
endif.

Hi Ravi,

Please check this sample codes.

DATA: c_file_mask TYPE dxfields-filemask VALUE '*',
      searched_dir TYPE dxfields-longpath,
      file_path LIKE dxfields-longpath.

searched_dir = 'INITIAL_DIRECTORY_TO_START_WITH'.
TRANSLATE searched_dir TO LOWER CASE .

CALL FUNCTION 'F4_DXFILENAME_TOPRECURSION'
  EXPORTING
    i_location_flag = 'A'
    i_server = ' '
    i_path = searched_dir
    filemask = c_file_mask
* FILEOPERATION = 'R'
  IMPORTING
* O_LOCATION_FLAG =
* O_SERVER =
  o_path = file_path
* ABEND_FLAG =
  EXCEPTIONS
    rfc_error = 1
    OTHERS = 2.

IF sy-subrc <> 0.
  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
  WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.

Hope this will help.
