Issue with internal table in object oriented ABAP.
Hello Gurus,
I am having trouble defining internal table in Object oriented ABAP. for following:
DATA: BEGIN OF IT_TAB OCCURS 0.
INCLUDE STRUCTURE ZCUSTOM.
DATA tot_sum TYPE char40.
DATA END OF IT_TAB.
Can someone help ?
Regards,
Jainam.

Moderator message - Please post in the correct forum. You can easily find out for yourself by looking at SAP help for internal tables using OOP - thread locked
Edited by: Rob Burbank on Feb 5, 2010 2:49 PMNo, you can not declare internal table with header line in OO context. You have to declare the work are/header line separately
Example:
TYPES: BEGIN OF ty_it_tab.
INCLUDE STRUCTURE mara.
TYPES: tot_sum TYPE char40.
TYPES: END OF ty_it_tab.
DATA: it_tab TYPE STANDARD TABLE OF ty_it_tab.
DATA: wk_tab TYPE ty_it_tab.
LOOP AT it_tab INTO wk_tab.
ENDLOOP.

Public attributes
Public attributes are defined in the PUBLIC section and can be viewed and changed from outside the class. There is direct access to public attributes. As a general rule, as few public attributes should be defined as possible.
PUBLIC SECTION.
DATA: Counter type i.
Private attributes
Private attributes are defined in the PRIVATE section. The can only be viewes and changed from within the class. There is no direct access from outside the class.
PRIVATE SECTION.
DATA: name(25) TYPE c,
planetype LIKE saplane-planetyp,
Instance attributes
There exist one instance attribute for each instance of the class, thus they exist seperately for each object. Instance attributes are declared with the DATA keyword.
Static attributes
Static attributes exist only once for each class. The data are the same for all instances of the class, and can be used e.g. for instance counters. Static attributes are defined with the keyword CLASS-DATA.
PRIVATE SECTION.
CLASS-DATA: counter type i,
Public methods
Can called from outside the class
PUBLIC SECTION.
METHODS: set_attributes IMPORTING p_name(25) TYPE c,
p_planetype LIKE saplane-planetyp,
Private methods
Can only be called from inside the class. They are placed in the PRIVATE section of the class.
Constructor method
Implicitly, each class has an instance constructor method with the reserved name constructor and a static constructor method with the reserved name class_constructor.
The instance constructor is executed each time you create an object (instance) with the CREATE OBJECT statement, while the class constructor is executed exactly once before you first access a class.
The constructors are always present. However, to implement a constructor you must declare it explicitly with the METHODS or CLASS-METHODS statements. An instance constructor can have IMPORTING parameters and exceptions. You must pass all non-optional parameters when creating an object. Static constructors have no parameters.
Static constructor
The static constructor is always called CLASS_CONSTRUCTER, and is called autmatically before the clas is first accessed, that is before any of the following actions are executed:
Creating an instance using CREATE_OBJECT
Adressing a static attribute using
Calling a ststic attribute using CALL METHOD
Registering a static event handler
Registering an evetm handler method for a static event
The static constructor cannot be called explicitly.
Protected components
When we are talking subclassing and enheritance there is one more component than Public and Private, the Protected component. Protected components can be used by the superclass and all of the subclasses. Note that Subclasses cannot access Private components.
Polymorphism
Polymorphism: When the same method is implemented differently in different classes. This can be done using enheritance, by redefining a method from the superclass in subclasses and implement it differently.

Interfaces
In ABAP interfaces are implemented in addition to, and independently of classes. An interface only has a declaration part, and do not have visibillity sections. Components (Attributes, methods, constants, types) can be defined the same way as in classes.
Interfaces are listed in the definition part lof the class, and must always be in the PUBLIC SECTION.
Operations defined in the interface atre impemented as methods of the class. All methods of the interface must be present in the
implementation part of the class.
Attributes, events, constants and types defined in the interface are automatically available to the class carying out the implementation.

Subclassing
This example uses a superclass LCL_AIRPLANE and subclasses it into LCL_PASSENGER_AIRPLANE and LCL_CARGO_PLANE.
LCL_AIRPLANE has a method display_n_o_airplanes that displays the number of object instances.
LCL_PASSENGER_AIRPLANE has the private instance attribute n_o_seats, and redefines the superclass method display_attributes, so it also displays n_o_seats.
LCL_CARGO_PLANE has the private instance attribute cargomax, and redefines the superclass method display_attributes, so it also displays cargomax.
All instance attributes are provided by the cunstructor method.

The method estimate_fuel_consumption is implemented differently in the 3 classes, as it depends on the airplane type.
Object from different classes are stored in an internal table (plane_list) consisting of references to the superclass, and the processed
identically for all the classes.
What coding for the estimate_fuel_consumption method taht is actually executed, depends on the dynamic type of the plane reference variable,
that is, depends on which object plane points to.

1. Simple class
This example shows how to create a simple employee class. The constructor method is used to initialize number and name of thje employee when the object is created. A display_employee method can be called to show the attributes of the employee, and CLASS-METHOD dosplay_no_of_employees can be called to show the total number of employees (Number of instances of the employee class).

2. Inheritance and polymorphism
This example uses a superclass lcl_company_employees and two subclasses lcl_bluecollar_employee and lcl_whitecollar_employee to add employees to a list and then display a list of employees and there wages. The wages are calcukated in the method add_employee, but as the wages are calculated differently for blue collar employees and white collar emplyees, the superclass method add_employee is redeifined in the subclasses.
Principles:
Create super class LCL_CompanyEmployees.
The class has the methods:
Constructor
Add_Employee - Adds a new employee to the list of employees
Display_Employee_List - Displays all employees and there wage
Display_no_of_employees - Displays total number of employees
Note the use of CLASS-DATA to keep the list of employees and number of employees the same from instance to instance.
Create subclasses lcl_bluecollar_employee and lcl_whitecollar_employee. The calsses are identical, except for the redifinition of the add_employee method, where the caclculation of wage is different.
Methodes:
Constructor. The constructor is used to initialize the attributes of the employee. Note that the constructor in the supclasss has to be called from within the constructor of the subclass.
Add_Employee. This is a redinition of the same method in the superclass. In the redefined class the wage is calcuated, and the superclass method is called to add the employees to the emploee list.:

Debugging a Module Pool Program(Object Oriented ABAP)
Hello Experts,
Could you please advise me on an efficient debugging technoque of Module Pool Program which is based on Object Oriented ABAP?Hi
Debugging Module pool program using ABAP objects is same as debugging any other report/module pool program.
Click on the Create shortcut icon on the toolbar.
In the popup window choose "System command" and in the command enter "/h"
A shortcut on the desktop would be created
Drag and drop the shortcut to the modal window to set debugging on.
Approach 2:
Create a txt file on the desktop with the following lines:
[FUNCTION]
Command=/H
Title=Debugger
Type=SystemCommandDrag and drop this file to the modal window to set debugging on.
How do I switch between the Classic and New Debugger
From within the ABAP workbench, select the Utilities->Settings Menu
Select the ABAP Editor Tab
Select the Debugging tab within the ABAP Editor Tab
Select the Classic Debugger or New Debugger radio button

Learning tips for Object Oriented ABAP
Hi Gurus,
I am in ABAP for last 1 year,
I want to learn Object oriented ABAP can you please guide me where to start.
Some learning material etc.
Regards
BikasNormal ABAP is process oriented, where is OOP-ABAP is a new methodology in ABAP which uses object oriented programming.
we have C++, java, C#, etc as OOP languages.
ABAP has also implemented the OOP technology.
it uses classes, methods and interfaces instead of functiongroups and function modules.
As part of SAPs long-standing commitment to object technology, Release 4.0
of R/3 will contain object-oriented enhancements to the ABAP programming
language. SAPs object strategy is based on SAP Business Objects and now
covers modeling, programming, interfacing, and workflow. By using principles
like encapsulation, inheritance, and polymorphism, the object-oriented
extensions of ABAP will support real object-oriented development. This will
result in improvements in the areas of reusability, maintenance, and quality of
code. SAP offers an evolutionary approach toward objects which leverages
SAPs own and its customers investments in existing business processes,
functionality and data.

Object-oriented + ABAP Objects
Hello friends,
I would like to know, is it possible in ABAP Objects to do the followings:
Single Inheritance
Multiple Inheritance
Polymorphism
Data Abstration
Method Overloading, and method Overriding
Inner Classes ?
Would be nice if some one highlights some of the features of ABAP Objects, in comparision or in regards to JAVA or so...
Many thanks in advance...Hi,
In ABAP : We do have final concept!
There are differencies between 'Local Classes' created in abap wihtin One program : for example Handler for ALV Grid
And Repository classes : Created in the repository available for any program!
Multi threading can be done via asynchronous Function module or with event!
greetz!

CLASS LCL_EVENT_RECEIVER DEFINITION DEFERRED.
Please let me know the meaning of the statement in declaring the class.
Reward is compulsary.Hi vijay,
1. Usually the class along with the
definition, should be coded FIRST.
2. but some times,
due to some reasons,
we want to write the code
for definition,
after some lines ,ie ... below.
3. So that syntax error is not recevied,
WE HAVE TO TELL ABAP ABOUT THIS .
4. so, as the name suggests,
DEFINITION DEFERRED,
we use like this.

Regarding "Friend Function" in Object oriented Abap.
Hi! Every Body,
I need to know about this friend function in ooabap.
1. Clear Definition.
2. i need program too.
3. What is the use Of friend function?
4. wht is the difference from java and ooabap using this function.
if any body replies for my query , i really thank full to u.
regards,
M.swapna.
[email protected]Hi Swapna,
Usually private components of a class can be accessed by methods of that class only..Sometimes, it is necessary for two classes to work so close to each other that one class needs to access the private attributes of the other.
In that case, you can make the former class, a friend of the latter class.
Suppose class A is made as a friend of class B.
Then A and its subclasses can access the private or protected components of the class B.
But they cannot access the private or protected components of subclasses of class B.
You can refer this link for more help.
