file path error in same screen.

Former Member — Mon, 12 Sep 2005 14:21:34 GMT

hey guys,

I want to check my file path validation and display error in same screen itself.

I used my GUI_UPLOAD method in START OF SELECTION. to read the file.

If error it displays error in some other plain screen.

I know AT selection screen will allow me to display in same screen.

But is the way of using GUI_UPLOAD method in AT selection screen is advisable?

or else please give me alternate way.

Hi Ambhi,

If you want to validate for existance of file

use

DATA : l_f_exist(1).

CALL FUNCTION 'TMP_GUI_GET_FILE_EXIST'

EXPORTING

fname = p_inp

IMPORTING

exist = l_f_exist

EXCEPTIONS

fileinfo_error = 1

OTHERS = 2.

IN AT SELECTION SCREEN.

<i>I assume you are not validating data in the file at selection screen.</i>

You can use in AT Selection screen

data result.

CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_EXIST

EXPORTING

FILE = 'C:\test.txt'

RECEIVING

RESULT =

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.

the return parameter will be "X" if file exists else it will be blank.

Cheers

Hi Ambi,

You can do the GUI_UPLOAD in the AT SELECTION-SCREEN event, provided you do that only when the user presses the 'Execute' or 'F8' button. That way you will avoid doing it all the time. AT SELECTION-SCREEN will be executed before the START-OF-SELECTION and any error you give there, the processing stops there and you remain in the selection screen.


AT SELECTION-SCREEN.

  CASE sscrfields-ucomm.
    WHEN 'ONLI'.
      CALL FUNCTION 'GUI_UPLOAD'
         ........
         .....
    WHEN OTHERS.
  ENDCASE.

To valid the existance of file in presentation or application server u can use SXDA_FILE_EXISTENCE_CHECK

CALL FUNCTION 'SXDA_FILE_EXISTENCE_CHECK'

EXPORTING

DS_NAME = P_FPATH "file path

DATA_APP = 'X'

DATA_REM = SPACE

SERVER = SPACE

DATA_FRN = SPACE

PC_FILE = SPACE

IMPORTING

FILE_EXISTS = W_XFLAG

EXCEPTIONS

RFC_FAILURE = 1

FRONTEND_ERROR = 2

DB_ERROR = 3

OTHERS = 4.

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

STOP.

ENDIF.

IF W_XFLAG EQ 'X'.

WRITE:/001 'File exists'.

ELSE.

WRITE:/001 'File does not exists'.

ENDIF.

regards
