All you need to do is evaluate SY-SUBRC after the OPEN statement, if it is not 0, then it either does not exist or you don't have permission to open it, I think 4 is that it does not exist, and 8, means that you don't have permission. Anyway, simply check the value of SY-SUBRC after the OPEN DATASET statement.

Hi,

Open the file using the OPEN DATASET syntax..If the return code is not successful..then the file does not exits.



OPEN DATASET '/tmp/test.txt' FOR INPUT.

IF SY-SUBRC <> 0.
  MESSAGE 'Error in opening file or file does not exists'.
ENDIF.

Thanks

Hi,

Please try something like this.


AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_apath.
 
* Open the Browse Dialog Box on the Application Server
CALL FUNCTION '/SAPDMC/LSM_F4_SERVER_FILE'
  IMPORTING
    serverfile = p_apath
  EXCEPTIONS
    canceled_by_user = 1
    others = 2.
 
IF sy-subrc <> 0.
  ...                                   " Error Message
ENDIF.
