Hi,

WS_DOWNLOAD is obsolete now,its recommended to use CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD(when background processing is required)

For your info:

GUI_* and WS_* function modules do not work in background

Chk this link for some sample programs:

Hi ,

the difference is ws_* is used in Older versions. and also it is Obsolete. so you should go For GUI_* or

CL_GUI_FRONTEND_SERVICES=>GUI_UP/DOWNLOAD methods.

Hai,

in ws_download is Obsolete in Higher Versions

file type is as follows

PARAMETERS: P_FILE LIKE RLGRAP-FILENAME. "local file with contracts

CALL FUNCTION 'DOWNLOAD'

EXPORTING

FILENAME = ' '

FILETYPE = I_TYPE

DATA_TAB = T_DOWNLOAD

INVALID_FILESIZE = 1

in gui_download -->is using instead of 'ws_upload'

Please explain how to use cl_gui_frontend services,

I didn't find the difference between gui_download and cl_gui... I observered in that class-gui_download method contains same function module 'gui_download'.

Thanks

Hi,

Its just the object oriented way of handling gui_download.

HI

GOOD

GUI_DOWNLOAD=>

GUI_DOWNLOAD Replaces WS_DOWNLOAD. Download table from the app server to presentation server

WS_DOWNLOAD=>

WS_DOWNLOAD Save Internal Table as File on the Presentation Server

EXAMPLE->

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

FILENAME = 'C:\Errors.Txt'

FILETYPE = 'ASC'

TABLES

DATA_TAB = E_INT_0015.

THANKS

HI Tripaty,

I hope your statement about ws_download is wrong.

Both function modules are used for downloading data to presentation servers from internal table.

But ws_download is obsolete as the versions are upgraded.

[Former Member]

I'm working with Unicode system I need to use cl_gui...instead of ws_upload.(filename, itab).

Please provide an idea how to it

thanks

OK try the following..

        w_filetable like file_table-filename,
        w_subrc     type i.
  data: w_filename type string.

  case sy-subrc.
    when 0.
      read table t_filetable index 1 into w_filetable.

Hi,

the basic difference is in one the parameters are defined in runtime while in the other they are defined in the function module.

for gui_download, the file name anf file type paramteres are passed during the runtime. they are not exported in the function module while in the ws_download, these two parameters need to be passed.

Which method or function module works in background? I've tried SCMS_DOWNLOAD, WS_DOWNLOAD and GUI_DOWNLOAD but doesn't work in background. Any sugestions?

[former_member194669]

Any of this will not work in background. For background mode you need to use syntax

OPEN DATASET l_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

Please don't bump old threads (unless there is a valid reason to do so) and use the search first if you suspect that the question has been asked before.

Thanks,
