Hi Hari,
There are some nice tutorials and introductory articles and presentations in SDN.
If you do a media search on ABAP Objects you will find:
1)Eight Reasons Why Every ABAP Developer Should Give ABAP Objects a Second Look by Horst Keller

There is also an excellent class offered by SAP Education called BC401 that describes Objects and BADIs in exruciating detai ;-).

  • ABAP Classes and BADIs for HR

    Hi all,
    Can anyone give me a list of classes SAP has released for HR use by customers and all utility ABAP classes. Also any utility abap classes that would be useful for future. I am only interested in those relevant for ECC 5 and up.
    Could you supply the BADIs or Enhancement Spots for HR too.
    Thanks
    Wayne

    The BADI's I have found most useful are the BADI exits that duplicate the existing PA30 PAI / PBO User exits.  If you trace back to where the exits are called you will find the BADI call within a few lines of code - but the difference is that the BADI is called outside one layer of IF logic, so it gets called in some circumstances where the user exits do not - I think this was to do with certain change or copy data situations.
    Can't remember the name of the BADI, and do not have a system available to check at present, but it was not hard to find when I looked in the system.
    Others I have used are as exits in the HR to FI posting interface, and also some in the travel to vendor interface.  There is also an exit for customising the PERNR search help - cannot remember if this was a class or a FM.
    For moving data inside the user exits in a unicode compliant way there are classes for moving data from the flat PRELP character structure to individual infotype structures - CL_HR_PNNNN_TYPE_CAST=>PRELP_TO_PNNNN and CL_HR_PNNNN_TYPE_CAST=>PNNNN_TO_PRELP.
    For general unicode compliant constants such as a Tab character there is class CL_ABAP_CHAR_UTILITIES with attributes like CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB.
    Also if you go to SE38, select the Blue "Online Help" button, and then go to the ABAP Overview, you will find under the ABAP by Theme branch an entry "ABAP System Classes and Interfaces" which documents 20+ general ABAP classes
    Hope this helps

    Remote Function Call:
    RFC is an SAP interface protocol. Based on CPI-C, it considerably simplifies the programming of communication processes between systems.
    RFCs enable you to call and execute predefined functions in a remote system - or even in the same system.
    RFCs manage the communication process, parameter transfer and error handling.

  • File to Proxy Scenario using ABAP Class and DB Multi Connect

    Hello Friends,
    I have a scenario below and a proposed solution. I would like some input as to whether i am headed the right way.
    Scenario: Thousands of records come in from the legacy accounting system. The fields of these records need to be mapped to SAP fields using cross-reference tables stored in DB2. Finally, summarize the records by deleting a few fields and feed to R/3.
    Solution i proposed:
    (1) File Adapter is used to send the file
    (2) Although JDBC adapter comes first to mind but since i need to access the DB2 tables multiple times for each record i propose to use an ABAP class for the mapping. Within the ABAP class the intent is to open an database connection to DB2, read the relevant cross tables using native SQL and finally generate the output XML.
    (3) Reciever is Proxy which feeds this generated XML to SAP for creating posting via BAPI_ACC_DOCUMENT_POST
    Question: Is the above solution correct or is there a better method to implement this scenario?
    Please let me know.
    Thanks,
    Minhaj.

    Looks fine. Few observations -
    1. Whether it is ABAP class or Mapping in RFC lookup, you are making multiple trips to the database.
    2. It looks like PI is being used only for reading the file and converting it to XML.
    3. If using PI is not mandatory, then a complete ABAP class on ECC it self would be faster than swtching between PI Java, PI ABAP then round trips to DB2 finally data push to ECC.
    If you could look at something like fetching all the required RFC look up data in one go and then map the fields according, might save u on processor and network resources.

  • Deleted standard class and BAdI. Need to re-generate/re-import.

    Hello SAPients,
    My buddy was working on the implementation of a BAdI. He arrived to a point where he couldn't save the Implementation because the system showed the error "Interface doesn't exist". He thought that deleting the implementation and re-creating it he would be able to save the implementation but then the system requested for an Access Key to modify the object, he requested the Key to the Basis guys, they provided it and my buddy deleted the implementation (that's what he thought). Actually, something weird happened and he deleted the class and the BAdI. Now, we are having trouble with short dumps in standard TCodes. The question is, is it posible to re-generate/re-import this standard objects? How?
    Thanks in advance for your kind help.

    I already told him that.
    BAdI: FTR_CUSTOMER_EXTENT.
    Class: CL_EX_FTR_CUSTOMER_EXTENT.
    We have too many developers working on this system, if we restore it from a backup we'll lose their work.
    Any other idea?
    Thanks.

  • Model provider class and data provider class

    please explain Model provider class and data provider class?

    Hi,
    both MPC and DPC get generated as runtime artifacts.
    MPC - This is used to define model. you can use the method Define to create entity, properties etc using code based implementation. you rarely use MPC extension class.
    DPC - used to code your CRUDQ methods as well as function import methods. you write all your logic in redefined methods of DPC extension class.
    Refer Generated ABAP Classes and Service Registration - SAP NetWeaver Gateway - SAP Library for more information.
    you can also refer my blog Let’s code CRUDQ and Function Import operations in OData service! which will provide you clear idea on how to redefine various CRUDQ methods in DPC extension class.

  • Web reporting - changeging abap classes

    I have got an extremely fussy user who would like the complex search facility shown at the bottom of the value help popup screen hidden (HELP SERVICE : DP_VIEW_FILTER).
    I assume I will have to copy the relevant ABAP class and modify it.
    Could anyone please advise me
    1. Which ABAP class I need to change?
    2. What I would need to change in this class to remove the complex search fields/buttons?
    3. How I would call the class from a web report?
    4. Is this far to complex a task to be worth even considering?
    Many thanks

  • Evaluation classes and cumulation classes

    Hi All ,
       Can anybody give the information about evaluation classes and cumulation classes in HR and how they affects the payroll.It is better for me if any one give the scenario to understand these concepts.I know the basics of these things i.e in which view these details are maintained for wagtypes.
    Thanks in advance.
    Regards ,
    Santosh.

    Hi Santosh,
    For any wagetype to process in payroll these cummulation class and evlatuion class is important.As payroll is Country specific each county has specific base for calculating Cummulation class.
    Cummulation Class: In payroll there are two types of cummulation
    (a) Cummulation of wage types over another wage type
    (b) Cummulation of wage types over a period of time
    For the first one it is used to calculate the base for different tax calculation. It is represented by /1 series wage types. Examples  For HRA Basis it is /111  and the base is mainly Basic+DA...etc.
    For the second one it is calculated by Processing class 30 Specification 0,1,2,3 and T. The related tables are V-T54c1, V_T54c4 and V_T54c3
    Evaluation Class: This  is used mainly for reports i,e Form 16, Form 24, Payslips etc. In India mostly used Evaluation classes are
    02 - For Payments and Deductions in Payslip
    06 - For Sec 17(1) For Total Gross
    07 - For Sec 10 Deductions
    09 - For Sec 17(3) For Perks
    08 - For Sec 17(2) For Income from other sources
    11 - For Sec 217 2 (A)
    * All these reports you can see in table V-T512w_D or V_t512w_O
    I think this will help you

  • How can I call a ABAP proxy class from BADI? PLease help

    hi Experts,
        I have a scenario where I have to call a ABAP proxy class from a BADI. How can I do this? Does anybody has sample code for the same?
    Please help.
    Thanks
    Gopal

    Hi,
       You can call a method of a class from BADI. Here are the steps.
       1) In the BADI implementation create a object for the proxy class.
       2) Call the Execute_Synchronous method.
        You can define a BADI by using SE18 and you can implement it by using SE19.
    Sample code...
    ================================================
      METHOD ZIF_EX_VBADI~CONVERTUPPER.
      DATA: OBJ TYPE REF TO ZTESTCLASS.
      DATA: IT_DATA  TYPE ZIN_MT,

  • I want the Definitaion fo  Class and its Components  in ABAP . With Example

    Gowri

    <b>Classes</b>
    Classes are templates for objects. Conversely, you can say that the type of
    an object is the same as its class. A class is an abstract description of an object. You could say that it is a set of instructions for building an object. The attributes
    of objects are defined by the components of the class, which describe the
    state and behavior of objects.
    <b>
    Local and Global Classes</b>
    Classes in ABAP Objects can be declared either globally or locally. You define global classes and interfaces in the Class Builder (Transaction SE24) in the
    ABAP Workbench. They are stored centrally in class pools in the class library
    in the R/3 Repository. All of the ABAP programs in an R/3 System can access the global classes. Local classes are defined within an ABAP program. Local classes and interfaces can only be used in the program in which they are defined. When you use a class in an ABAP program, the system first searches for a local class with the specified name. If it does not find one, it then looks for a global class. Apart from the visibility question, there is no difference between using a global class and using a local class.
    There is, however, a significant difference in the way that local and global classes are designed. If you are defining a local class that is only used in a single program, it is usually sufficient to define the outwardly visible components so that it fits into that program. Global classes, on the other hand, must be able to be used anywhere. This means that certain restrictions apply when you define the interface of a global class, since the system must be able to guarantee that any program using an object of a global class can recognize the data type of each interface parameter.
    The following sections describe how to define local classes and interfaces in an ABAP program. For information about how to define local classes and interfaces, refer to the  Class Builder section of the ABAP Workbench Tools documentation.
    <b>Defining Local Classes</b>
    Local classes consist of ABAP source code, enclosed in the ABAP statements CLASS ... ENDCLASS. A complete class definition consists of a declaration part and, if required, an implementation part. The declaration part of a class <class> is a statement block:
    CLASS <class> DEFINITION.
    ENDCLASS.
    It contains the declaration for all components (attributes, methods, events) of the class. When you define local classes, the declaration part belongs to the global program data. You should therefore place it at the beginning of the program.
    If you declare methods in the declaration part of a class, you must also write an implementation part for it. This consists of a further statement block:
    CLASS <class> IMPLEMENTATION.
    ENDCLASS.
    The implementation part of a class contains the implementation of all methods of the class. The implementation part of a local class is a processing block. Subsequent coding that is not itself part of a processing block is therefore not accessible.
    <b>Structure of a Class</b>
    <u>The following statements define the structure of a class:</u>
    A class contains components
    Each component is assigned to a visibility section
    Classes implement methods
    The following sections describe the structure of classes in more detail.
    <b>Class Components</b>
    The components of a class make up its contents. All components are declared in the declaration part of the class. The components define the attributes of the objects in a class. When you define the class, each component is assigned to one of the three visibility sections, which define the external interface of the class. All of the components of a class are visible within the class. All components are in the same namespace. This means that all components of the class must have names that are unique within the class.
    There are two kinds of components in a class - those that exist separately for each object in the class, and those that exist only once for the whole class, regardless of the number of instances. Instance-specific components are known as instance components. Components that are not instance-specific are called static components.
    In ABAP Objects, classes can define the following components. Since all components that you can declare in classes can also be declared in interfaces, the following descriptions apply equally to interfaces.
    <b>Attributes</b>
    Attributes are internal data fields within a class that can have any ABAP data type. The state of an object is determined by the contents of its attributes. One kind of attribute is the reference variable. Reference variables allow you to create and address objects. Reference variables can be defined in classes, allowing you to access objects from within a class.
    <b>Instance Attributes</b>
    The contents of instance attributes define the instance-specific state of an object. You declare them using the DATA statement.
    <b>Static Attributes</b>
    The contents of static attributes define the state of the class that is valid for all instances of the class. Static attributes exist once for each class. You declare them using the CLASS-DATA statement. They are accessible for the entire runtime of the class.
    All of the objects in a class can access its static attributes. If you change a static attribute in an object, the change is visible in all other objects in the class.
    <b>Methods</b>
    Methods are internal procedures in a class that define the behavior of an object. They can access all of the attributes of a class. This allows them to change the data content of an object. They also have a parameter interface, with which users can supply them with values when calling them, and receive values back from them The private attributes of a class can only be changed by methods in the same class.
    The definition and parameter interface of a method is similar to that of function modules. You define a method <met> in the definition part of a class and implement it in the implementation part using the following processing block:
    METHOD <meth>.
    ENDMETHOD.
    You can declare local data types and objects in methods in the same way as in other ABAP procedures (subroutines and function modules). You call methods using the CALL METHOD statement.
    <b>Instance Methods</b>
    You declare instance methods using the METHODS statement. They can access all of the attributes of a class, and can trigger all of the events of the class.
    <b>Static Methods</b>
    You declare static methods using the CLASS-METHODS statement. They can only access static attributes and trigger static events.
    <b>Special Methods</b>
    As well as normal methods, which you call using CALL METHOD, there are two special methods called CONSTRUCTOR and CLASS_CONSTRUCTOR, which are automatically called when you create an object (CONSTRUCTOR) or when you first access the components of a class (CLASS_CONSTRUCTOR).
    <b>Events</b>
    Objects or classes can use events to trigger event handler methods in other objects or classes. In a normal method call, one method can be called by any number of users. When an event is triggered, any number of event handler methods can be called. The link between the trigger and the handler is not established until runtime. In a normal method call, the calling program determines the methods that it wants to call. These methods must exist. With events, the handler determines the events to which it wants to react. There does not have to be a handler method registered for every event.
    The events of a class can be triggered in the methods of the same class using the RAISE EVENT statement. You can declare a method of the same or a different class as an event handler method for the event <evt> of class <class> using the addition FOR EVENT <evt> OF <class>.
    Events have a similar parameter interface to methods, but only have output parameters. These parameters are passed by the trigger (RAISE EVENT statement) to the event handler method, which receives them as input parameters.
    The link between trigger and handler is established dynamically in a program using the SET HANDLER statement. The trigger and handlers can be objects or classes, depending on whether you have instance or static events and event handler methods. When an event is triggered, the corresponding event handler methods are executed in all registered handling classes.
    <b>Instance Events</b>
    You declare instance events using the EVENTS statement. An instance event can only be triggered in an instance method.
    <b>Static Events</b>
    You declare static events using the CLASS-EVENTS statement. All methods (instance and static methods) can trigger static events. Static events are the only type of event that can be triggered in a static method.
    <u>See also Triggering and Handling Events.</u>
    <b>Types</b>
    You can define your own ABAP data types within a class using the TYPES statement. Types are not instance-specific, and exist once only for all of the objects in a class.
    <b>Constants</b>
    Constants are special static attributes. You set their values when you declare them, and they can then no longer be changed. You declare them using the CONSTANTS statement. Constants are not instance-specific, and exist once only for all of the objects in a class.
    <b>Visibility Sections</b>
    You can divide the declaration part of a class into up to three visibility areas:
    CLASS <class> DEFINITION.
      PUBLIC SECTION.
      PROTECTED SECTION.
      PRIVATE SECTION.
    ENDCLASS.
    These areas define the external visibility of the class components, that is, the interface between the class and its users. Each component of a class must be assigned to one of the visibility sections.
    <b>Public Section</b>
    All of the components declared in the public section are accessible to all users of the class, and to the methods of the class and any classes that inherit from it. The public components of the class form the interface between the class and its users.
    <b>
    Protected Section</b>
    All of the components declared in the protected section are accessible to all methods of the class and of classes that inherit from it. Protected components form a special interface between a class and its subclasses. Since inheritance is not active in Release 4.5B, the protected section currently has the same effect as the private section.
    <b>Private Section</b>
    Components that you declare in the private section are only visible in the methods of the same class. The private components are not part of the external interface of the class.
    <b>Encapsulation</b>
    The three visibility areas are the basis for one of the important features of object orientation - encapsulation. When you define a class, you should take great care in designing the public components, and try to declare as few public components as possible. The public components of global classes may not be changed once you have released the class.
    For example, public attributes are visible externally, and form a part of the interface between an object and its users. If you want to encapsulate the state of an object fully, you cannot declare any public attributes. As well as defining the visibility of an attribute, you can also protect it from changes using the READ-ONLY addition.
    "Example  :
    CLASS C_COUNTER DEFINITION.
      PUBLIC SECTION.
        METHODS: SET_COUNTER IMPORTING VALUE(SET_VALUE) TYPE I,
                 INCREMENT_COUNTER,
                 GET_COUNTER EXPORTING VALUE(GET_VALUE) TYPE I.
      PRIVATE SECTION.
        DATA COUNT TYPE I.
    ENDCLASS.
    CLASS C_COUNTER IMPLEMENTATION.
      METHOD SET_COUNTER.
        COUNT = SET_VALUE.
      ENDMETHOD.
      METHOD INCREMENT_COUNTER.
        ADD 1 TO COUNT.
      ENDMETHOD.
      METHOD GET_COUNTER.
        GET_VALUE = COUNT.
      ENDMETHOD.
    ENDCLASS.
    The class C_COUNTER contains three public methods - SET_COUNTER, INCREMENT_COUNTER, and GET_COUNTER. Each of these works with the private integer field COUNT. Two of the methods have input and output parameters. These form the data interface of the class. The field COUNT is not outwardly visible.
