Main difference between these 2 methods

HI
what is the main difference between updateOrder and repriceOrder methods in any form handler
please give me exact difference

Both are totally different operations. repriceOrder method invokes the pricing engines and calculators to calculate the order prices whereas, updateOrder method saves the changed order properties to the database.
Thanks,

Could someone advise me about the difference between these two
api:
wwsso_api_user_admin.change_password and
wwsso_api_user_mgr.change_password
Are these api the same?Are they affecting the same table?
Thanks in advance for any clarification

What is the main difference between LOCAL VARIABLE, REFERENCE, PROPERTY NODE and INVOC. NODE?
Can u show this with an example in a VI using all these?
Basic overview. Someone can go into more depth if they want.
Local Variable - Correlates to some location in memory that holds information. Based on the data type, it looks at that location and interprets the 1's and 0's as either a double, integer, string, structure(cluster), etc.
Reference - ill leave the details of this to someone else I can't give a decent explanation.
Property node- sets different "properties" of a control/indicator etc. One of the properties is value so that works similar to a local variable. However, you can set much more than that. For example, with controls you can set the property of visible, not visible, color, etc etc.
Invoke node - invokes some "method." i.e. calls some function to act on something
These may not be the best explanations, or even 100% correct. But it should get you started. I'm sure someone else will build on this.

What is the difference between these setter methods

What is the difference between these two setter methods??
<jsp:useBean id="checking" scope="session" class="bank.Checking" />
<jsp:setProperty name="checking" property="balance" value="0.0" /> and
<jsp:useBean id="checking" scope="session" class="bank.Checking" >
<jsp:setProperty name="checking" property="balance" value="0.0" />
</jsp:useBean>

Homework question?

Can anyone tell me the difference between these String methods?

There are methods that can convert a byte[] into string:
String(byte[] ascii, int hibyte, int offset, int count)
String(byte[] bytes, int offset, int length)
String(byte[] bytes)
I am now sticking on it. The first one runs great in my project, but it is deprecated. The remaining two return wrong answer I need. Can anyone expain what the difference between them? Really appreciate the help, thanks in advance.

It seems like the first one translates each byte into one character. The other two use the default character encoding to translate possibly more than one byte into each character. Look up Unicode character encodings to understand the difference.

What is the difference between these to methods?

public void firstMethod(){
     int x = 5;
}and
public int secondMethod(){
     int x = 5;
     return x;
}I just don't see the difference. I guess I am still a little confused on what the return statement does.

The return statement just alows me to use the method as a type of variable, right?The proper explanation is that expressions can evaluate to either l-values or r-values, where an l-value is something to which you can assign an r-value. So in the statement "x = x + 1;", the first x evaluates to an l-value (which you can normally think of as the location of x - doesn't make so much sense when you're thinking in terms of stack machines like the JVM), and the second x evaluates to an r-value (the value currently stored in x), as does the expression "x + 1". If you have a method returning type T, you can substitute a call to that method anywhere you have an expression which evaluates to an r-value of type T.
From a practical point of view, you don't need return statements, but by not using them you constrain yourself to either having very large methods or using lots of global variables.

Question about main difference between Java bean and Java class in JSP

Hi All,
I am new to Java Bean and wonder what is the main difference to use a Bean or an Object in the jsp. I have search on the forum and find some post also asking the question but still answer my doubt. Indeed, what is the real advantage of using bean in jsp.
Let me give an example to illustrate my question:
<code>
<%@ page errorPage="errorpage.jsp" %>
<%@ page import="ShoppingCart" %>

<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
<html>
<head><title>Shopping Cart</title></head>
<body bgcolor="#FFFFFF">
Your cart's ID is: <%=cart.getId()%>.
</body>
<html>
</code>
In the above code, I can also create a object of ShoppingCart by new operator then get the id at the following way.
<code>
<%
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
%>
</code>
Now my question is what is the difference between the two method? As in my mind, a normal class can also have it setter and getter methods for its properties. But someone may say that, there is a scope="session", which can be declared in an normal object. It may be a point but it can be easily solved but putting the object in session by "session.setAttribute("cart", cart)".
I have been searching on this issue on the internet for a long time and most of them just say someting like "persistance of state", "bean follow some conventions of naming", "bean must implement ser" and so on. All of above can be solved by other means, for example, a normal class can also follow the convention. I am really get confused with it, and really want to know what is the main point(s) of using the java bean.
Any help will be highly apprecaited. Thanks!!!

Alex

Hi All,
I am new to Java Bean and wonder what is the main
difference to use a Bean or an Object in the jsp. The first thing to realize is that JavaBeans are just Plain Old Java Objects (POJOs) that follow a specific set of semantics (get/set methods, etc...). So what is the difference between a Bean and an Object? Nothing.
<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
In the above code, I can also create a object of
ShoppingCart by new operator then get the id at the
following way.
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
...Sure you could. And if the Cart was in a package (it has to be) you also need to put an import statement in. Oh, and to make sure the object is accessable in the same scope, you have to put it into the PageContext scope. And to totally equal, you first check to see if that object already exists in scope. So to get the equivalant of this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart"/>Then your scriptlet looks like this:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = pageContext.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    pageContext.setAttribute("cart", cart);
%>So it is a lot more work.
As in my mind, a normal class can also
have it setter and getter methods for its properties.True ... See below.
But someone may say that, there is a scope="session",
which can be declared in an normal object.As long as the object is serializeable, yes.
It may be
a point but it can be easily solved but putting the
object in session by "session.setAttribute("cart",
cart)".Possible, but if the object isn't serializable it can be unsafe. As the point I mentioned above, the useBean tag allows you to check if the bean exists already, and use that, or make a new one if it does not yet exist in one line. A lot easier than the code you need to use otherwise.
I have been searching on this issue on the internet
for a long time and most of them just say someting
like "persistance of state", "bean follow some
conventions of naming", "bean must implement ser" and
so on. Right, that would go along the lines of the definition of what a JavaBean is.
All of above can be solved by other means, for
example, a normal class can also follow the
convention. And if it does - then it is a JavaBean! A JavaBean is any Object whose class definition would include all of the following:
1) A public, no-argument constructor
2) Implements Serializeable
3) Properties are revealed through public mutator methods (void return type, start with 'set' have a single Object parameter list) and public accessor methods (Object return type, void parameter list, begin with 'get').
4) Contain any necessary event handling methods. Depending on the purpose of the bean, you may include event handlers for when the properties change.
I am really get confused with it, and
really want to know what is the main point(s) of
using the java bean.JavaBeans are normal objects that follow these conventions. Because they do, then you can access them through simplified means. For example, One way of having an object in session that contains data I want to print our might be:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    session.setAttribute("cart", cart);
%>Then later where I want to print a total:
<% out.print(cart.getTotal() %>Or, if the cart is a JavaBean I could do this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session"/>
Then later on:
<jsp:getProperty name="cart" property="total"/>
Or perhaps I want to set some properties on the object that I get off of the URL's parameter group. I could do this:
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    cart.setCreditCard(request.getParameter("creditCard"));
    cart.setFirstName(request.getParameter("firstName"));
    cart.setLastName(request.getParameter("lastName"));
    cart.setBillingAddress1(request.getParameter("billingAddress1"));
    cart.setBillingAddress2(request.getParameter("billingAddress2"));
    cart.setZipCode(request.getParameter("zipCode"));
    cart.setRegion(request.getParameter("region"));
    cart.setCountry(request.getParameter("country"));
    pageContext.setAttribute("cart", cart);
    session.setAttribute("cart", cart);
}Or you could use:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session">
<jsp:setProperty name="cart" property="*"/>
</jsp:useBean>The second seems easier to me.
It also allows you to use your objects in more varied cases - for example, JSTL (the standard tag libraries) and EL (expression language) only work with JavaBeans (objects that follow the JavaBeans conventions) because they expect objects to have the no-arg constuctor, and properties accessed/changed via getXXX and setXXX methods.

Whats the difference between these two queries ? - for tuning purpose

Whats the difference between these two queries ?
I have huge amount of data for each table. its takeing such a long time (>5-6hrs).
here whice one is fast / do we have any other option there apart from listed here....
QUERY 1:
SELECT --<< USING INDEX >>
      field1, field2, field3, sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end)
    FROM
      tab1 inner join tab2 on condition1 inner join tab3 on condition2 inner join tab4 on conditon3
    WHERE
     condition4..10 and
    GROUP BY
      field1, field2,field3
    HAVING
      sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end) <> 0;
QUERY 2:
   SELECT --<< USING INDEX >>
      field1, field2, field3, sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0))
    FROM
      tab1, tab2, tab3, tab4
    WHERE
     condition1 and
     condition2 and
     condition3 and
     condition4..10
    GROUP BY
      field1, field2,field3
    HAVING
      sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0)) <> 0;
[pre]

My feeling here is that simply changing join syntax and case vs decode issues is not going to give any significant improvement in performance, and as Tubby points out, there is not a lot to go on. I think you are going to have to investigate things along the line of parallel query and index vs full table scans as well any number of performance tuning methods before you will see any significant gains. I would start with the Performance Manual as a start and then follow that up with the hard yards of query plans and stats.
Alternatively, you could just set the gofast parameter to TRUE and everything will be all right.

What are the main differences between 3 three important class types

PP members
What are the main differences between class type 300(variants) , class type 200 (configurable objects) & 001 ( material class)
Please elucidate on the above
Thanks
Suren R

Hi,
The class type is a central concept in the classification system. The class type determines how classes are processed, and how objects can be classified and retrieved in these classes. In Customizing for Classification, you define the settings for a class type. You define class types for a specific object type, such as materials. You can then use classes of this class type to classify objects of this object type.
When you first create a class, you must enter a class type for the class. Each class type is a closed system. There is no link between the different class types.
he class type determines the following:
Which object types you can assign to a class
Which class maintenance functions you can process
Whether you can classify objects in more than one class
Which class statuses, organizational areas, and text types are supported in class maintenance functions
Whether you can use engineering change management for classification
Which filter functions you can use to restrict the search result
All materials can be classified with class type 001. Class type 300 is for variant configuration the variants under a class item are called as variants and can be picked during sales order creation. Class type 200 is for classes that are used as class items in bills of material. You can classify the same materials separately in these class types.
This is basically used to differentiate the BOM class items.

What is the difference between organisation payment method and Assignment payment method?

What is the difference between organisation payment method and Assignment payment method?
As i am a new bie, i am curious to know this though it might sound a silly question.
Thank you,
Kuton

You can create an Organization payment method of any Payment type(Cash, Check, BACS, NACHA etc) under the same country.
All these will be valid payment methods on the payroll description form.
And you can even attach these to a person.
In which case you will have a Base currency (say USD) and payment currency (say GBP).
These cases are not normal and only used by people who use a single BG for paying employees in 3-4 countries.
So, unless you need to pay in different currencies, do not use it.

What is the main difference between eewb and aet tool ?

Dear all,
What is the main difference between eewb and aet? Both ways we can create fields and coming to aet is in crm 7.0 and eewb is in 6.0.when we are creating fields through eewb we should have technical knowledge but aet tool is a simple tool as a function people also can easily add the fields. I want to know is there any main difference between both these tools.
Regards,
Jemmi.

EEWB works from SAP GUI whereas AET works from WEB UI. AET is developed on top of the EEWB. Most the Objects are supported barring a few through AET. It's a very usefull tool for SAP CRM.
Since in CRM SAP GUI will be phased out soon, AET will be prominent. One will see lot more features in upcoming relase in AET tool.

What is the main difference between Enhancements and BADI.?

What is the main difference between Enhancements and BADI.?plzz tell
Edited by: Alvaro Tejada Galindo on Feb 13, 2008 3:48 PM

CMOD is the Project Management of SAP Enhancements (i.e., SMOD Enhancements). SMOD contains the actual enhancements and CMOD is the grouping of those SMOD enhancements.
Difference Between BADI and User Exits
BADI's can be used any number of times, where as USER-EXITS can be used only one time.
Ex:- if your assigning a USER-EXIT to a project in (CMOD), then you can not assign the same to other project.
BADI's are oops based.
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
As with customer exits two different views are available:
In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.
In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.
In contrast to customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.
SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time. In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example).
All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard. A single Business Add-In contains all of the interfaces necessary to implement a specific task.
The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects.

What is the main difference between menu_exits and user_exits

what is the main difference between menu_exits and user_exits

Hi,
User Exits:
A user exit is a three character code that instructs the system to access a program during system processing.
SXX: S is for standard exits that are delivered by SAP. XX represents the 2-digit exit number.
UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number
Menu Exits:
Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.

Difference between batch input method and batch input recording in LSMW?

hi,
plz tell me the difference between batch input method and batch input recording in LSMW?
thanks & regards
Ruban

Hi Ruban,
The main difference between the two is in lsmw we can view the code status at any time just by coming to prvious steps, but whereas in batch input method unless the recording is finished we cant view the code.
second diff is tht we need to do lot of coding in batch inptu whereas here in lsmw we need not do much coding and mapping to data.
third diff is that batch input is both inbound and outbound where as lsmw is only inbound.
hope u got the differences.....
Regards,
sana M...
