How to validate a mentioned file path?

Former Member — Thu, 29 Dec 2005 06:49:42 GMT

Hi,

I have joined the forum recently.

How to check if a local path in sel.screen is valid?.

I have already checked the FMs PC_CHECK*. These FMs do not actually access the PC and check for existence of mentioned path.

Thanks,

Madhu

Hi,

I want to create a file, say log.txt in the mentioned path. I would do this using WS-DOWNLOAD. But first I want to ascertain that the mentioned path exists in the PC.

Thanks,

Hi,

You can use the same file path in WS_download and do this in at selection-screen event.

You will get an FILE_OPEN_ERROR exception if the path is not correct. (SY-SUBRC = 1)

Hope it helps...

Pls. reward appropriate points

Try FM DX_FILE_EXISTENCE_CHECK.

If you enter the path including file name in import parameter 'FILENAME'and enter value X gainst import parameter PC, you will get value for export parameter FILE_EXISTS as X if the file is present.

CONV_UTIL_CHECK_FILE_EXISTENCE

CV120_DOC_FILE_EXISTENCE_CHECK

CV122_DOC_FILE_EXISTENCE_CHECK

DX_FILE_EXISTENCE_CHECK

PFL_CHECK_OS_FILE_EXISTENCE

try this following code

selection-screen begin of block b1 with frame .

PARAMETER : FILE(100) lower case.

selection-screen end of block b1.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE.

CALL FUNCTION 'WS_FILENAME_GET'

EXPORTING

DEF_FILENAME = ' '

DEF_PATH = '.'

MASK = ' '
MODE = ' '
TITLE = ' '

IMPORTING

FILENAME = FILE

RC =

Hi Vijay,

The FM CV120_DOC_FILE_EXISTENCE_CHECK works fine for local path.

Thanks,
