down laod file problem

Former Member — Mon, 03 Nov 2008 18:41:36 GMT

Hi Friends,

I am using the below code downloading file

but I am getting the short dump like 'Acess denied'.

TYPES: BEGIN OF xml_line_dl,

data(10000) TYPE c,

END OF xml_line_dl.

data: gv_filename_dld TYPE string value 'c:\abc.xml '.

data: xml_table_dld TYPE TABLE OF xml_line_dl.

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

filename = gv_filename_dld

filetype = 'ASC'

TABLES

data_tab = xml_table_dld.

Please suggest me I need to avoid the short dump If I dont have the acess to 'C:\' drive

Insted of short dump I need to populate the error message If I dont have the acess to C derive

ThanX

Sam

Hi,

You can use the Exception's of the Function module for this..

Try handling the exceptions.

MOVE p_file TO xfile.

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

filename = xfile

filetype = 'ASC'

IMPORTING

filelength = bytes_written

TABLES

data_tab = t_out

fieldnames = t_output

EXCEPTIONS

file_write_error = 1

no_batch = 2

gui_refuse_filetransfer = 3

invalid_type = 4

no_authority = 5

unknown_error = 6

header_not_allowed = 7

separator_not_allowed = 8

filesize_not_allowed = 9

header_too_long = 10

dp_error_create = 11

dp_error_send = 12

dp_error_write = 13

unknown_dp_error = 14

access_denied = 15

dp_out_of_memory = 16

disk_full = 17

dp_timeout = 18

file_not_found = 19

dataprovider_exception = 20

control_flush_error = 21

OTHERS = 22.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

After the function call check SY-SUBRC

if SY-SUBRC = 15.

endif.

Hi,

Do like this...

Call function GUI_DOWNLOAD using pattern button and uncomment the Exceptions parameters.

Then use the Exception ACCESS_DENIED, you will get sy-subrc = 15, and you can populate your error/information message here only.

For eg:

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

BIN_FILESIZE =

filename = filename

FILETYPE = 'ASC'
APPEND = ' '

WRITE_FIELD_SEPARATOR = 'X'

HEADER = '00'

TRUNC_TRAILING_BLANKS = 'X '

WRITE_LF = 'X'
COL_SELECT = ' '
COL_SELECT_MASK = ' '
IMPORTING
FILELENGTH =

tables

data_tab = ITAB

EXCEPTIONS

FILE_WRITE_ERROR = 1

NO_BATCH = 2

GUI_REFUSE_FILETRANSFER = 3

INVALID_TYPE = 4

NO_AUTHORITY = 5

UNKNOWN_ERROR = 6

HEADER_NOT_ALLOWED = 7

SEPARATOR_NOT_ALLOWED = 8

FILESIZE_NOT_ALLOWED = 9

HEADER_TOO_LONG = 10

DP_ERROR_CREATE = 11

DP_ERROR_SEND = 12

DP_ERROR_WRITE = 13

UNKNOWN_DP_ERROR = 14

ACCESS_DENIED = 15

DP_OUT_OF_MEMORY = 16

DISK_FULL = 17

DP_TIMEOUT = 18

FILE_NOT_FOUND = 19

DATAPROVIDER_EXCEPTION = 20

CONTROL_FLUSH_ERROR = 21

OTHERS = 22

Case sy-subrc.

When 15.

*Write your message here.

endcase.

using exceptions is the best practice.
