Diff between gui_upload &? ws_upload

Question

can any one tell me what is the difference between gui_upload and ws_upload.

Answer 1

Hi harish
WS_UPLOAD function module is now obsolete
from 4.7 ,gui_upload is used., this supports OOPs.
check this
WS_UPLOAD and WS_DOWNLOAD, the function modules used until now are not part of the standard set of ABAP commands. They are used to display the file interface on the presentation server. WS_UPLOAD and WS_DOWNLOAD are not compatible with USs and have been replaced by GUI_UPLOAD and GUI_DOWNLOAD.
The new function modules, GUI_UPLOAD and GUI_DOWNLOAD, have an interface that also allows you to write Unicode format to the local hard drive.
Instead of using the function modules, you can use the static methods GUI_UPLOAD and GUI_DOWNLOAD of the global class CL_GUI_FRONTEND_SERVICES.
These classes are used to convert ABAP data from the system format to external formats and vice versa. During this conversion process, character-type data may be converted to another character set, while numeric-type data may be converted to another byte order (or endian format). You must use a container of type X or XSTRING for data in an external format.
Character sets and endian formats are also converted by the file interface (OPEN DATASET with new additions), RFCs, and the function modules GUI_DOWNLOAD and GUI_UPLOAD. The classes described below are available for those special cases where the possibilities offered by conversion are insufficient. Since these classes work with containers of types X and XSTRING, these containers can be copied unconverted by the file interface (OPEN DATASET with new additions), RFCs, and the function modules GUI_DOWNLOAD and GUI_UPLOAD. These classes replace the following two statements:
TRANSLATE c ...FROM CODE PAGE     g1 ... TO CODE PAGE     g2
TRANSLATE f ...FROM NUMBER FORMAT n1 ... TO NUMBER FORMAT n2
For a detailed description, see the class documentation in the Class Builder. The following classes are available:
CL_ABAP_CONV_IN_CE
Reads data from a container and converts it to the system format. You can also fill structures with data.
CL_ABAP_CONV_OUT_CE
Converts data from the system format to an external format and writes it to a container.
CL_ABAP_CONV_X2X_CE
Converts data from one external format to another.

Converts data from one external format to another.
