Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload
         exporting
              filename                = filename
              filetype                = 'ASC'
         changing
              data_tab                = iflatf
         exceptions
              file_open_error         = 1
              file_read_error         = 2
              no_batch                = 3
              gui_refuse_filetransfer = 4
              no_authority            = 6
              unknown_error           = 7
              bad_data_format         = 8
              unknown_dp_error        = 12
              access_denied           = 13
              others                  = 17.

What is the difference between UPLOAD and WS_UPLOAD?

Hi,
What is the difference between UPLOAD and WS_UPLOAD?
Best Regards,
Gopal

Hi,
Both upload and ws_upload does the same functionality, that is transfere data from presentation server to application server or from PC to SAP system(to an internal table).
There are very few difference between the two.
1 Upload requires a User Interaction for uploading i.e., user has to respond to the dialog boxes that appear WS_Upload does not. You just need to specify the file location in the function input parameters itself.
2 upload - u can give the file in run time wsupload - u have to give in Function module
3 upload is meant to be used by abappers. ws_upload is meant to be called by SAP. It is not a standard ABAP command.
4 ws_upload is Obsolete : No longer supported by SAP. Use GUI_UPLOAD instead.
The fm WS_UPLOAD was the first version of fm to get a file from presentation server, now from 4.6 it's obsolete, the new fm is GUI_UPLOAD.
The fm UPLOAD is the fm used in several applications, like ABAP editor, to upload the file.
In the some versions (it depends on patch level) UPLOAD can call WS_UPLOAD (or GUI_UPLOAD).
Last but not the least, 'upload' internally calls 'ws_upload', that's the difference.
Hope this would be helpful.

Diff between gui_upload &? ws_upload

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

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.
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.

What is the programming (ABAP) difference between Unicode and non Unicode?

What is the programming(ABAP) difference between Unicode and non Unicode?
Edited by: NIV on Apr 12, 2010 1:29 PM

Hi
The difference between programming in Unicode or not Unicode is that you should consider some adjustments to make on the Program "Z" to comply with the judgments Unicode Standard.
In the past, developments in SAP using multiple systems to encode the characters of different alphabets. For example: ASCII, EBCDI, or double-byte code pages.
These coding systems mostly use 1 byte per character, which can encode up to 256 characters. However, other alphabets such as Japanese or Chinese use a larger number of characters in their alphabets. That's why the system using double-byte code page, which uses 2 bytes per character.
In order to unify the different alphabets, it was decided to implement a single coding system that uses 2 bytes per character regardless of what language is concerned. That system is called Unicode.
Unicode is also the official way to implement ISO/IEC 10646 and is supported in many operating systems and all modern browsers.
The way of verifying whether a program was adjusted or not, is through the execution of the UCCHECK transaction. Additionally, you can check by controlling syntax (making sure that this asset verification check Unicode).
The main decisions to adjust / replace are (examples):
ASSIGN H-SY-INDEX TEXT TO ASSIGN <F1> by
H-SY-INDEX TEXT (*) TO <F1>.
DATA INIT (50) VALUE '/'. by
DATA INIT (1) VALUE '/'.

Null means, the referential type is not assigned (doesn't refer) to a specific object. The empty String is just another object though, so seeing it or pointing it out as something special when it actually isn't at all (no more special than new Integer(0) or new Object[0]) just adds to the confusion.

Difference between char and varchar, also the difference between varchar2

Hi,
Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
Example 1:
SQL> create table tchar(text1 char(10), text2 varchar2(10))
2 /
Table created.
SQL> insert into tchar values('krystian','krystian')
2 /
1 row created.
SQL> select text1, length(text1), text2, length(text2)
2 from tchar
3 /
TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
krystian 10 krystian 8
Example 2:
create table tvarchar(text varchar(10))
SQL> select table_name,column_name,data_type
2 from user_tab_columns
3 where table_name = 'TVARCHAR'
4 /
TABLE_NAME COLUMN_NAME DATA_TYPE
TVARCHAR TEXT VARCHAR2

The difference between SFP+ and X2

Dear Expert,
I need to know what is the difference between SFP+ and X2! and can I use SFP+ card and module instead of X2?
Thanks,
Mohammad Saeed

Hi,
They are both used for 10Gig interfaces. The difference is the connector type.
SFP+ is LC and X2 is SC.
You can not put an SFP+ into an X2 slot or X2 optic into a SFP+.

Difference between ok_code and sy-ucomm

Hi,
Can any one tell me the difference between ok_code and sy-ucomm

Hi,
Actually OK_CODE and SY-Ucomm are the same. But experts suggest use of OK code for following reason:
In each PAI event that a user triggers by choosing either a pushbutton on the screen or an element in a GUI status, the corresponding function code is placed into the system field SYST-UCOMM or SY-UCOMM and placed in the OK_CODE field (as long as the function code is not empty). Empty function codes are placed in neither the SY-UCOMM field nor the OK_CODE field.
In your ABAP programs, you should work with the OK_CODE field instead of SY-UCOMM. There are two reasons for this: Firstly, the ABAP program has full control over fields declared within it, and secondly, you should never change the value of an ABAP system field. However, you should also always initialize the OK_CODE field in an ABAP program for the following reason:
In the same way that the OK_CODE field in the ABAP program and the system field SY-UCOMM receive the contents of the corresponding screen fields in the PAI event, their contents are also assigned to the OK_CODE screen field and system field SYST-UCOMM in the PBO event. Therefore, you must clear the OK_CODE field in the ABAP program to ensure that the function code of a screen is not already filled in the PBO event with an unwanted value. This is particularly important when the next PAI event can be triggered with an empty function code (for example, using ENTER). Empty function codes do not affect SY-UCOMM or the OK_CODE field, and consequently, the old field contents are transported.

What is difference between abstraction and encapsulation ?

Hi,
I am trying to figure out the difference between abstraction and encapsulation but confused.
Both are used for data hiding then what is the exact difference ?
Thanks.

When you encapsulate something you get an inside and an outside. The outside is the abstraction. It describes how the encapsulated entity behaves viewed from the outside. This is also called the type. Hidden inside is the implementation. It holds detail information about how the type's behaviour is accomplished.
It's a very simplified picture but I think it's quite accurate and it works for me.
