Difference between BSP and webdynpro

can any one explain the difference between bsp and webdynpro and also the advatages over each other?

Hi,
The main diffrence between this 2 keeping client requirement in mind if LOOK & FEEL.
In webdynpro we have very less scope for geeting the look and feel but in BSP we have more scope for Customization.
In webdynpro we have some predefined methods known as Hook Methods which will handle the flow .
I mean to say some code which we write commonly will be reduced in webdynpro.
So that the time for building the application will be very less compared to BSP.
For example if you take MVC architecture implementation BSP and webdynpro
webdynpro provide built in MVC functionality where as in BSP we have to implement it using controllers,views,etc...
Finally Developing application in web dynpro takes less time then in BSPs
Thanks & Regards,

Diff between BSP and WEBDYNPRO FOR ABAP?

Hi All,
can anyone let me know the Difference between BSP's and WEBDYNPRO FOR ABAP.
Regards,
Ravi

Hi Ravi,
In truth, Web Dynpro contains many of the enhancements than BSPs....like built-in value-help and select options...... they
will become standard in Web Dynpro. But these can also be added to BSPs also.
There are several architectural differences between BSP and WDA. WDA has some advanced features but more restrictive framework compared to BSP.
WDA is stateful only. While BSP supports both stateful and stateless programming models.
WDA doesn't aloow us to use our own custom HTML, JavaScript or other controls. To provide compatibility the rendering logic is completely hidden from the developer.
On the other hand, BSP has no such restrictions and allows an extreme level of custom rendering. This makes BSP a perfect platform for applications that require pixel-perfect layout or specialized UI elements.

What is the difference between ERP2004 and SAP 47 Enterprise?

Currently we have SAP 47 Enterprise with WAS 6.2. I understand ERP2004 is NW and 6.4 sp9. Can any one please let me know the major difference between ERP2004 and SAP 4.7 Enterprise ( more from abap / workflow view)?
Thanks
Swamy

From Abap point of view some of the major add-on in erp2004,netwever :
1) Development of webdynpro studio for java development for portal and iviews.
2) Major abap development uses <b>Abap object oriented</b> methodology, rathet hten old conventional Abap,i.e MVC model (Model,View,Controller) where in it uses concept of classes,interfaces,etc.
3) Advanced BSP tech using MVC model to develop web based modules
4) It is closesly integrated with web-based CRM and BW/APO

Difference between automatic and non-automatic page attributes

Hi,
Can anyone tell me difference between automatic page attributes and non-automatic page attributes?
and also difference between stateful and stateless mode with examples?
Thanks
Narendra

Hi Mullapudi,
If you mark a page attribute as u2018automaticu2019 (auto in the system), the attribute automatically gets its values via the calling URL or
via the navigation process from other pages.
This kind of attribute only has to be declared for one page.
It is identified by its name equivalence.
If another page uses a parameter with the same name,
at runtime that parameter automatically
gets the same values as the attribute.
Non-automatic page attributes
If you flag a page attribute as non-automatic, the attribute gets its values from the class attribute.
The visibility of page attributes when parameters are transferred between BSP pages depends on whether the navigation is explicit or implicit.
Explicit navigation
For example, if navigation->goto_page(page.htm)
Implicit navigation
With implicit navigation, the page attributes are transferred automatically from OnInputProcessing to OnInitialization, both in stateful and stateless mode.
The auto page attributes are refilled by the request, both in stateful and stateless mode.
Reward if Useful...

Difference between Null and null?

What is the difference between null and NULL?
When is each used?
Thanks,

veryConfused wrote:
There is a null in java, but no NULL. null means no value. However, when assigning value, the following is different:Although the empty String has no special role. 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 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.

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.

What is difference between Iterator and Collection Wrapper?

Hi all,
I dont understand the actual difference between Iterator and Collection Wrapper. I observed both are used for the same purpose. Could any one please let me know when to use Collection Wrapper and when to use Iterator??
Thanks,
Chinnu.

L_Kiryl is right.
Collections support global iteration (through collection->get_next( )) and local iteration (through iterator->get_next( )).
Each collection has a focus object. Initially, the first object has the focus.
Any global iteration moves the focus, which is published by the event FOCUS_CHANGED of the collection.
If you want to iterate on the collection without moving the focus (and without triggering timeconsuming follow-up processes) you can use local iteration. To do so, request an iterator object from the collection and use this to iterate.
And one more advantage of using iterator: it takes care of deleted entities. If you use global iteration then when you reach deleted entity it will be an exception. But there is no exception with iterator in the same situation.
