Download problem

[Former Member]

Hi all,

I am using WS_DOWNLOAD to download to local PC.But when any value like 'sdfhbhb' is entered in the file path the system does not prompt any exception from the FM.

Is there any FM to validate the path.

Pls post ur Ideas.

Thanks,

Hi,

First take the valid file path from the user .

Using this

CONSTANTS :

lc_dft_ext TYPE string VALUE 'XLS',

lc_file_flt TYPE string VALUE '*.xls',

lc_int_drc TYPE string VALUE 'C:\'.

DATA : lv_win_title TYPE string,

lv_file_name TYPE string,

lv_dft_fname TYPE string,

lv_fname TYPE string,

lv_path TYPE string.

CLEAR: lv_fname,

lv_path,

lv_file_name,

lv_win_title,

lv_dft_fname.

--

Set File Details F4 Based on Report Type--

IF xv_indicator = lc_s.

lv_win_title = text-045.

lv_dft_fname = text-038.

ELSE.

lv_win_title = text-044.

lv_dft_fname = text-033.

ENDIF.

CALL METHOD cl_gui_frontend_services=>file_save_dialog

EXPORTING

window_title = lv_win_title

default_extension = lc_dft_ext

default_file_name = lv_dft_fname

file_filter = lc_file_flt

initial_directory = lc_int_drc

prompt_on_overwrite = lc_true

path = lv_path

fullpath = lv_file_name

OTHERS = 4.

IF sy-subrc <> 0 OR lv_fname IS INITIAL

OR lv_path IS INITIAL

OR lv_file_name IS INITIAL.

CLEAR xyv_filepath.

ELSE.

*---FilePath

xyv_filepath = lv_file_name.

ENDIF.

<b>there are many method in this cl_gui_frontend_services realeted to this.

u can use FILE_EXIST method to validate the existence of the file

that is cl_gui_frontend_services=>FILE_EXIST

Then use download.

using GUI_DOWNLOAD instead of WS_DOWNLOAD F.M

Before Download your internal Table into PC Flat file

the filename must exist in your given path

otherwise create on flie in the PC then do the bellow code

Check the following Code

data : v_ecc6_filename type string.

data : begin of it_mara occurs 0,

matnr like mara-matnr,

mbrsh like mara-mbrsh,

mtart like mara-mtart,

meins like mara-meins,

end of it_mara.

select

matnr

mbrsh

mtart

meins

from mara

into table it_mara

where mtart = 'ROH'.

v_ecc6_filename = 'C:\Down_Load.txt'.

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

FILENAME = 'C:\new.txt'

FILETYPE = 'ASC'

TABLES

DATA_TAB = it_mara

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

Hi,

I tried with GUI_DOWNLOAD,but it short dumps on invalid file name as 'jfdbvjb' .Also I do not want to hardcode any directory(eg. C:\) or filename(eg.Download) or file extension(eg. .xls,.dat) in the program.

Pls post ur ideas.

Thanks ,

can you send your code

[Former Member]

Hi again,

1. Also I do not want to hardcode any directory(eg. C:\) or filename(eg.Download) or file extension(eg. .xls,.dat) in the program.

For this, just copy paste this program.

2. It will give selection

for selecting the filename

and download to that file.

3.

REPORT abc.

DATA : file_name TYPE string.

data : t001 like table of t001 with header line.
