Hi
What is the difference between USR and USR1 data classes?

hey check out this,
Data class refer to the physical area in which the tables assigned to the data class are stored.

  • What is the difference between document class and normal class

    Hi,
    Please let me know what is the difference between document class and normal class.
    And I have no idea which class should call as document class or call as an object.
    Thanks
    -Actionscript Developer

    the document class is invoked immediately when your swf opens.  the document class must subclass the sprite or movieclip class.
    all other classes are invoked explicitly with code and need not subclass any other class.

  • What is difference between data base structure and stucure  in program

    what is difference between data base structure and stucure  declared in program  level . can  explain cleary if knows

    Hi,
    Data base structure is global decalaration you can reffer this structure in any of your developments, when ever you cahange this structure the changes automatically will get updated in all the programs.
    coming to structures in program it is local to your program only, if you want to change the structure again you have to open the program and do the necessary changes.
    Reward if useful.
    Thanks,

  • Difference between Data staging and Dimension Table ?

    Difference between Data staging  and Dimension Table ?

    Data Staging:
    Data extraction and transformation is done here.
    Meaning that, if we have source data in flat file, we extract it and load into staging tables, we take care of nulls, we change datetime format etc.. and after such cleansing/transformation at then end, load it to Dim/Fact tables
    Pros: Makes process simpler and easy and also we can keep track of data as we have data in staging
    Cons: Staging tables need space hence need memory space
    Dimension Table:
    tables which describes/stores the attribute about specific objects
    Below is star schema which has dimension storing information related to Product, Customer etc..

  • Difference between date info object in characteristics and keyfigure

    What is the difference between "date" data type in characteristic and keyfigure?
    Thanks in advance.
    Raj

    Hi Rajasekhar,
    If date is characteristics,query can be analysed based on date and filters can also be set using this date.
    If it is key figure query cannot be analysed based on date,
    Based on requirements,we have to decide whether it should be chatracteristic or key figure

  • Difference between Abstract Classes Vs Interface

    Hi,
    Can u pls mention all the differences between Abstract Classes and Interface.? I've mentioned the differences I've known here.
    Known Differences:
    (*) An interface cannot implement any methods, whereas an abstract class can.
    (*) A class can implement many interfaces but can have only one superclass
    Can U pls mention at what situation(practical situation) we've to go for abstract class or Interface?
    Tell me the situation when we have to go for abstract class?
    Tell me the situation when we have to go for interface?
    Please Reply me
    Thanks & Regards
    Venkatesh

    There are more differences, and one really important is that abstract classes can also define class variables, while interfaces cannot. I think the question of when to use interfaces or abstract classes is not always easy to answer, but yourself have pointed some tips you should be aware of :
    If you need that some funcionality of the class is derived by more than one "parent" then you should use interfaces, since you cannot extend more than one class.
    If your "superclass" needs to define some class variables then the choice must be made to have a superclass and then extend it. Also this is applicable if there is a method that can be programmed at a higher level (in interfaces you cannot program methods).
    But the answer to the question is still not easy. And remember, you can always mix both tipes, you can extend one class and implement some interfaces.
    Examples or that are very common in the Java API for AWT or Swing components, for example javax.swing.JLabel extends javax.swing.JComponent (that is beacuse a JLabel IS a JComponent and it uses some variables and methods programmed at the JComponent "level") and it also implements some interfaces: Accessible, ImageObserver, MenuContainer, Serializable & SwingConstants.
    I hope this helps.

  • Find difference between date

    I need to know how i can find difference between date
    like Joining date: 01-jan-2009 Today 10-jan-2010 result will be "1 year 10 days"
    I need it in Oracle forms 6i. plz help me...

    Hi,
    In oracle forms you can use
    RESULT :=
    TRUNC ((:date2 - :date1 + 1) / 365)
    || ' year and '
    || MOD (:date2 - :date1 + 1, 365)
    || ' days';
    in sql you can use
    SELECT TRUNC ((:date2 - :date1 + 1) / 365)
    || ' year and '
    || MOD (:date2 - :date1 + 1, 365)
    || ' days'
    FROM DUAL;

  • Counter KF with 1 & 0 and difference between data type NUMBER (DEC) and INTEGER (INT4)

    Hi,
    I need to create a counter kf which should populate 1 and 0 to this counter field. Please let me know is there any difference between data type
    NUMBER (DEC) and INTEGER (INT4).
    Please suggest.
    Thanks & Regards,
    Pavan kumar

    Hi Pavan,
    The basic difference between Number(DEC) and INT4 is its internal storage in system.
    For Number (DEC) - Value internally stored as packed number with 3 decimal places whereas INT 4 as 4 byte integer without decimal places.
    For counter KF, you can go for INT 4.
    Hope this helps.
    Thanks

  • Difference between data target & Infoprovider.

    Hi all,
    Difference between data target & Infoprovider.
    why cube is best in performance wise other than ods,multiproviders.
    Thanks,
    cheta.

    A data target is an object into which data is loaded. Data targets are the physical objects relevant during data modeling and when loading the data.
    Structure
    Data targets are:
    InfoCubes
    ODS objects
          InfoObjects (characteristics with attributes, texts or hierarchies).
    There are differences between:
    Pure data targets for which no queries can be created or executed. An InfoCube might only be used as a data source for another InfoCube. This is also possible for ODS objects and InfoObjects.
    If you want a characteristic to appear in the InfoProvider tree, you have to assign an InfoArea to it. You can define update rules for the characteristic in the InfoProvider tree, and use them to load attributes and texts.
    You can turn a characteristic into a data target only if the characteristic contains texts or attributes. It is not possible to use update rules to load hierarchies.
    Data targets for which queries can be defined. These are called InfoProviders.

  • What is the difference between Abstract class and Interface ?

    Hi,
    Could u plz tell me the difference between Abstract class and Interface?
    Thanks in advance.
    Gopi

    Lots.
    An abstract class can contain some method implementations, or indeed all the method implementations. It may contain methods with all the various access modifiers. It cannot be instantiated. A class may inherit from only a single abstract class.
    An interface contains only public method stubs and constants. A class may implement multiple interfaces. An interface cannot (obviously) be instantiated.
    Abstract classes are particularly useful when you need to provide a semi-complete implementation for reuse. Interfaces are used more like types.
    Look at java.util.* for some good examples of the use of both.

  • Difference between Abstarct Class and Interface

    HI,
    Here is a simple one for the gurus but quite important for me.
    What is the difference b/w an Interface and an abstract class?
    Why do we need each one of them?
    I would appreciate if you people can give examples of each so that I amy understand fully
    Thanks in advance...

    A normal class (not abstract) has a special behaviour, like java.awt.Frame. A Frame is a frame no matter how you subclass it. If you create a subclass it will still be able to be displayed by calling it's show method. So by using a normal class you can create a type of class.
    An abstract class does the same, but it leaves some of the code unwritten. For instance java.lang.Number. This class is abstract becuase it has no knowledge of how to store the number in memory. But it knows that it is a number, and any subclass will still be a number. You could create a subclass of Number that can hold the time in milliseconds and checks your system clock to see what the time is, it could also have methods that return the time in another country, but it would still be just a Number.
    An interface is a way to describe what an object can do, not what it is. So with java.lang.Comparable as an example you can make any class comparable. This means that no matter what type of object you have, it can be compared with other objects. So you can have a subclass of Frame that can be compared with other windows. Or a subclass of Number that can be compared with other Numbers. You can even compare those two different types if you like. So you could compare a window with a number.
    That is the difference between abstract classes and interfaces.
    I hope you could follow my arguments, it isn't an easy subject,

  • What's the difference between batch class type 022 and 023?

    Hi Guys,
    I find that some of my SAP client only have class 022 and some have 023, but no client has  them all. I don't know why it happed.
    So what's the difference between batch class type 022 and 023?  Which setting decide which class to be used ?
    Thanks.

    Hi nitin,
    Read  http://www.sapfans.com/forums/viewtopic.php?t=212819&highlight=022  you will know the difference between 022 and 023 .
    Use tcode OMCT you can switch batch level .

  • The difference between batch class type 022 and 023

    what's difference between batch class type 022 and 023?  023 is described as standard batch class type, but there is only 022 type exists in my system. can i use 022?

    Hi,
    both classes mean the same, but which class is used is decieded by batch level. In case of material level or client level the system use automatically only class 023. If you define batch level to plant the system use automatically class 022.

  • Difference between Data Provider and extractor.

    Hi
    Can someone help me in understanding difference between data providers and data extractor.
    I have gone through some documents but not able to get the exact difference between them.
    What is the exact role of data provider and extractor with respect to sap solution manager.
    Is data provider== Data extractor?
    Thanks,
    Vijay

    Hello Vijaya,
    From my perspective the Data Providers are responsible for collecting metric values from the monitored objects on the managed sources systems and sending these to the Solution Manager Monitoring and Alerting Infrastrucure.
    Data extractors on the other hand are the reporting objects which are defined on the BW part of Solution Manager and can be enabled by configuring some monitoring scenario's. Once these data extractors are enabled, they will use the data from the "Data Providers" (see above) to setup nice BW reportings on the Solution Manager monitoring dashboards.
    I hope this answer helps you.
