Hi,

OPEN DATASET P_FILENAME for INPUT in TEXT MODE .
If SY-SUBRC EQ 0. 
 * File Exists
ELSE.
* File does not exit.
ENDIF.
or 

Check this Fm 'RZL_READ_DIR' 
                    'RZL_READ_FILE'

If sy-subrc NE 0.

Message 'File not found' type 'E'.

Endif.

priyanka,

You can put the open data set in try --- catch block and validate.

TRY.

OPEN DATASET P_FILENAME for INPUT in TEXT MODE .

CATCH cx_sy-file_open*

perform error_message.

ENDTRY

Hi ,

You can try using these two Function Modules:

To have an f4 help on the application server file

:F4_DXFILENAME_TOPRECURSION

And to validate the path use:

FILE_GET_NAME_USING_PATH

Hope it helps

Use the FM RZL_READ_DIR to get the file details of a directory.

Then you can check your file is exist or not.

OTHERS = 3.

IF sy-subrc NE 0.
