Gui_download and ws_download

Hi Guys,
What is the difference between gui_download and ws_download.

Hi,
WS_DOWNLOAD is an outdate and obselete.
Functionality of GUI_DOWNLOAD:
 File transfer from an internal table on the backend to a file on the
 presentation server.
 Storing SAP data in a file on the file system of the presentation
 server.
 The functionality is similar to that of module WS_DOWNLOAD. The
 difference is that the DataProvider is used for downloading the data
 instead of GMUX.
Example
 1.) Binary download (not converted)
 begin of itab,
 raw(255) type x,
 end of itab occurs 0.
 CALL FUNCTION 'GUI_DOWNLOAD'
 exporting
 bin_filesize = 500
 filetype = 'BIN'
 filename = 'C:\DOWNLOAD.BIN'
 tables
 data_tab = itab.
 loads 500 bytes of internal table itab into the file 'C:\DOWNLOAD.BIN'
 on the frontend PC. The data transferred is not converted.

Filename in gui_download and ws_download

Hi Friends..
if i using like this..
concatenate 'C:\'
              syst-date
              '.xls'
    into mc_filename.
in program and gave the mc_filname as a filename in the function module.its working fine in ws_download but it was not working in gui_download function module.
so please give your valuable suggetion regarding this..
Thanks
Gowrishankar

Hi Gowrishankar,
In WS_DOWNLOAD Function module Filename type is char but
In GUI_DOWNLOAD Function module Filename type is string.
so it is going to dump. first change the type of filename in your program
Plzz reward if it is helpful,

Actions - How to replace GUI_DOWNLOAD and CL_GUI_FRONTEND_SERVICES= FILE_SA

Hi,
In sap gui was trigered action whih is using smartform and then output was being downloaded and saved as using:
CALL FUNCTION 'GUI_DOWNLOAD' - to
CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_SAVE_DIALOG
After the ubgrade this action is not working in web ui.
Anyone knows how to change this to work in web ui?
Thank you in advance

Hi Tanja Lukovic
Pls check the settings defined in the SPRO path CRM->Basic settings->actions under this select your relevant application area and check whether any start/schedule conditions are not met (check in conditions) , apart from this reason there could be other reasons also pls check the trigger processing type (it should be smart form print).
if the actions are already created , you can change actions and conditions.
Thanks & Regards

GUI_DOWNLOAD and background processing

Hello,
I have created a process which creates a file. this process uses GUI_DOWNLOAD to put the file on the users C drive or other directory on our network. The user wants to run this process in background and the program is returning a 6 (error unknown) from the GUI_DOWNLOAD FM. I was looking on SDN and found out the GUI_DOWNLOAD only works in foreground. You have to use OPEN and CLOSE DATASET statements to process in background. I am thinking about putting a button to denote foreground/background processing and using the appropriate statements to process the file. I will then have to get the file from the app server to a place will the user can get access to it.
first question - is there a FM to do a FTP from the app server to a directory on our network for the user to access?
second question - is this the right approach or is there something else that I should be doing.
thanks in advance for your help

Hi,
Yes, your right, GUI_DOWNLOAD wil not work in background mode, you need to place the file in Application server, here.
See the below link for a FTP program, use the proper commands(i do not know whether downloading the file is possible through the commands)
http://www.sap-img.com/ab003.htm
or else, write a small program which downloads the data from the application server, but it should run in the foreground

What is difference between GUI_download and Open dataset

Dear All,
I know there are 2 options for downloading SAP data.
1) GUI_DOWNLOAD Functional Module.
2) OPEN DATASET DSET FOR OUTPUT IN TEXT MODE.
What is the difference ??
When I should use ?? What are the deciding factors ??
Regards
venkat

Hi All,
Thank You very Much for quick replies.
1) GUI_DOWNLOAD is used to download data into your local PC. can be run only in frontend.
2) OPEN DATASET is used for downloading into Application Server
Thank You one and all.
Closing Thread, Alloting Points.

Need help: GUI_DOWNLOAD and tab-separated in between fields.

hello everyone,
this is the layout of the interface that i created:
 sy-title
total records processed: XX
total records failed: XX
summary of the error
pernr<tab>name<tab>error message<tab>otherfieldshere
i wanted the error log to be saved locally thus, i have to use GUI_DOWNLOAD.
ok, here's the current parameters i supplied with my gui_download:
CALL FUNCTION 'GUI_DOWNLOAD'
 EXPORTING
 filename = v_file_string
 filetype = 'ASC'
 write_field_separator = 'X'
 TABLES
 data_tab = i_error_log
(exceptions not displayed)
the problem that i have is that, there is a difference between the error logs displayed after the execution and the error logs saved in my local directory.
i did find a way to resolve this BUT, i still need to refine it. also, the spaces between the fields seems not tab delimited, but separated by space.
to explain further here's the current error log that i have downloaded:
10000001<tab>10/23/2006<tab>01<tab>P<tab>11<tab>01
the header:
 sy-title
total records processed: XX
total records failed: XX
summary of the error
is not included in the downloaded errorlog file.
i added some modification of my report to include it because, i want to to look exactly the same as of the errorlog generated/displyed after the execution.
the result looks as it is what i've expected BUT,
when i checked the spaces in between fields...
it is all separated by spaces... not tab.
here is the actual error log that i have obtained:
 sy-title
total records processed: XX
total records failed: XX
summary of the error
pernr<space><space><space>name<space><space><space><space><space><space>error message<space><space>otherfieldshere
What i wanted to resolve is that, i want the error log to be tab delimited and not separated by space.
is this possible? if it is, any suggestion will truly be appreciated.

Hi,
Please check your flat file i think it they have used the Three spaces instead of using a SINGLE TAB. between the fields.
Thanks & Regards,
Chandralekha.

GUI_DOWNLOAD and codepage problem

I'm trying to download XML data using this function module to a local PC file. It contains finnish characters such as Ä.
When I open the XML file with an XML editor, it tells me that "Byte 0xFF found in file ... is invalid for encoding utf-8'
I think I need to save the file with ISO-8859-9 encoding, but I tried to use a codepage for that in the function module, and that also didn't work.
Can anybody suggest what I may be doing wrong?
CALL FUNCTION 'GUI_DOWNLOAD'
    EXPORTING
      filename                = l_filename
      filetype                = 'BIN'
      write_lf                = ' '
*     codepage                = '1611'
    TABLES
      data_tab                = lt_table.

Try using the following method:
TRY.
      cl_bcs_convert=>string_to_solix(
        EXPORTING
          iv_string   = lv_string
          iv_codepage = '1611'
          iv_add_bom = 'X'
        IMPORTING
          et_solix = binary_content
          ev_size   = size ).
    CATCH cx_bcs.
      MESSAGE e445(so).
ENDTRY.
For your table run it for every line and append the lines of the 'binary_content' into a collecting table (binary_content_all or something). Play with the BOM (Byte order mark) to see if you need it or not. After the table has been processed you can download the binary_content_all with your function module but I recommend using:
CALL METHOD cl_gui_frontend_services=>gui_download
    EXPORTING
      filename                  = l_filename
      filetype                  = 'BIN'
    CHANGING
      data_tab                  = binary_content
Let me know if this was helpful!
Cheers,

GUI_DOWNLOAD and spaces

Hi
I'm using GUI_DOWNLOAD to load data down to a local file. My internal table consists of 2 fields
field(660) type c,
spaces(12) type c.
I have two issues, when I down load the file, I'm not sure if I get 672 characters transfered to the text file, I have written some code to find the length of each line. When I try to read the file using notepad I have no idea how many characters are per row. Is theer any standard MS software that I can use to get the field length
Regards
J-J

Hi jim,
Add one more field to ur internal table EOD(1) " End of file
loop at itab into wa_itab.
itab-EOD = 'E'.
modify itab from wa_itab.
endloop.
then you can identify the end of file with E at the end

Cl_gui_frontend_services= gui_download and logical path issue

Hi all!!
I'm downloading a table with this class/method, and when i have worked with a LOCAL folder, it worked fine, but now, i need to put the file into a server folder. So i get the logical path in this way:
10.20.xx.xx
but when i pass the filename to the method: v_filename = '
10.20.xx.xx\file.txt' the file is not generated into this folder.. and i have permission to access and modify this folder..
Thanks for your feedbak!

If you need transfer each record of the table (I suppose itab with header line):
LOOP AT itab.
TRANSFER itab TO file_path
ENDLOOP.
Note: All of fields in itab must be character-type if the file was opened as a text file.
Other example:
OPEN DATASET '/usr/sap/tmp/ztest.txt' FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
IF sy-subrc EQ 0.
TRANSFER zdepmentt TO '/usr/sap/tmp/ztest.txt'.
ENDIF.
CLOSE DATASET '/usr/sap/tmp/ztest.txt'.
Here the content of the data object (flat structure) "zdepmentt" is transferred to the application server file '/usr/sap/tmp/ztest.txt'.
Note: The file ztest.txt is automaticaly created.

Using GUI_DOWNLOAD and FILE_SAVE_DOWNLOAD in WebDynpro

Hi Experts,
i have a WebDynpro, in which i try to create a FILE-Download-Window to save a File in the temp-folder.
For this i used the CL_GUI_FRONTEND_SERVICES=>FILE_SAVE_DIALOG and the the function GUI-DOWNLOAD. Both I tested in an report. they worked, but in the WebDynpro they didn't work.
Have anybody an idea for solving this problem?
Thanks a lot

Hi,
You need not use these Function modules in WD application because WD Object library provides options for uploading and Downloading function. Just use these buttons in your screen and the functions will come automatically.
