Hi Sreeram,

Check with TMP_GUI_GET_FILE_EXIST.

Hope this solves your problem.

Regards,

SB.

CL_GUI_FRONTEND_SERVICES=>FILE_EXIST

Example:


data:RCbool type ABAP_BOOL.
  WRITE: / 'TEST METHOD FILE_EXIST'.
  CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_EXIST
    EXPORTING
      FILE                 = 'c:\temp\test_frontend_services.txt'
    RECEIVING
      RESULT               = rcbool
*  EXCEPTIONS
*    CNTL_ERROR           = 1
*    ERROR_NO_GUI         = 2
*    WRONG_PARAMETER      = 3
*    NOT_SUPPORTED_BY_GUI = 4
*    others               = 5
          .
  IF SY-SUBRC <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.

  WRITE: / RCbool.

Hi,

You can check existence of a file in one of the 2 ways mentioned below:

1. Using function module 'DX_FILE_EXISTENCE_CHECK'.

2. Using Class Static Method 'CL_GUI_FRONTEND_SERVICES=>FILE_EXIST'

Do search on them and you will get all the details necessary.

Regards.
