Compare OOPs method and ABAP Subroutines

Hi SAP,
In my client interview i faced a question that is "Iam calling perform statement for about 100 times in my program and i have found that there is a performance issue and what is the solution you will give to improve the performance?"
I told by using methods.
He told correct.
But i want to know how technically methods are performing than routines. and why?
Thanks in Advance.

I think your Interviewer here has displayed a "pitiful" lack of understanding of this topic if he / she really actually thought this way. (The Person Giving the Interview not the person being asked the questions).
OOP is a different METHODOLOGY. I'll use a sales order for example.
OK in a sales order you have all sorts of data such as who the customer is, quantities and costs of the the line item(s), what the materials are, delivery instructions, delivery schedule lines etc etc. You might also need other data that comes from different SAP modules such as has the order been invoiced, has it been paid and has the amount been booked to the appropriate general ledger account.
In a "True" object orientated scenario all this data would be "encapsulated" into a single "Sales Order Object". All you would have to do is to "Instantiate" the sales order --I.e give it a key say sales order number and then WITHOUT ANY FURTHER PROGRAMMING all these "Attributes" or properties of the Sales order would be retiurned to your program.
As SAP is based on Relational data bases all this information needs to be read from the various distinct tables and your object is "Constructed". -- This is what the special method "Constructor" does when you first "Create " the object / instantiate it in your application program.
Constructing this object can take a considerable amount of time and resources depending on how much data needs to be read and from how many tables.
From then onwards you've got complete access to ALL the public attributes of the SALES ORDER class.
I'm leaving discussion of " Other Methods" out of this post as they are not totally relevant to the case in point.
When you call a function module you are bulding up possibly a single table or want to retrieve / post a document etc. This function module can be used anywhere and doesn't have any relationship to anything except the parameters it gets from calls in your application program.
For sequential processing of large numbers of "Objects" the system has a lot more work to do INITIALLY as it has to go through all the programming to build up all the attributes FOR EVERY OBJECT. For complex objects this could involve 100's of function module calls.
Now when we get to OBJECT Orientated data bases this will not be a problem as after creation the object will be stored in its entireity so no overhead in re-building all the attributes is incurred. (The JDO for those doing JAVA does a lot of this already when "persistent objects" are used).
So your "Interviwer" was really asking the wrong questions.
OO is MUCH MUCH simpler once the objects and classes have been correctly designed and constructed. Application programming and development time can be much reduced.
However depending on what your Function module is doing in your application load on the system could bet be much reduced compared with OO (at least until a genuine OO DBMS system is used).
In any case whether you perform a function 100 times or read all the data in one go it actually depends on what the function module actially does since you might NOT be able to retrieve everything in one go without locking the system up thereby causing longer response times for other users.
If you are running processes which are highly dependendent on the data you are accessing it could well be MUCH BETTER to retrieve this data in small doses since you won't lock the data segements for anything like the same amount of time.
OO in classical SAP does have implications with DATA INTEGRITY as well.
Say your OO aplication needs to UPDATE some of the attributes of a sales order you will need to LOCK those attributes against otherconcurrent updates being done against the "Standard SAP tables" via "Classical SAP processes and Transactions". Not an easy task here if the Class Object is complex.
However if used sensibly OO is the way forward and once OODBMS (Object Orientated data base systems) become more common place performance and data integrity issues will be solved.
Having used OO for a number of years I would certainly NEVER want to go back to classical ABAP.
Most problems with performance etc arise when people try and replicate standard sap transactions and programs with OO. DON'T -- IT DOESN'T WORK LIKE THAT.
If you really DO need to process loads of items sequentially you might find that using something like BW anyway is a better bet.
Finally not the answer most "techies" will appreciate" but Hardware is actually very cheap these days compared to programming time, using expensive external SAP consultants, etc etc.
It Might be financially more profitable in any case just to upgrade the hardware rather than spend the time and cost of re-writing old inefficient code. (Even lower cost "Abap Factories" in India/Singapore etc cost significant amounts of money and the rising economies of those countries means in any case that's not such a cheap option anymore).
The best time for re-writing is when you start a new project so you can design the thing using OO from the START. Don't try and fit a square peg into a round hole.
Cheers
Jimbo

OOP for abap

good morning to all sap experts,
i have a question for any OOP programmers in abap. i have been working in abap for over 12 years, but have not yet transitioned to oop. but, since we have been upgrading to ecc 6.0, i am constantly working with oop classes, and objects. maybe someone can answer these questions, and also point me in the right direction online, to educate myself.
i have a class that is called CL_WTY_CLAIM and it is running a method called get_direct_references. within get_direct_references, this line of code is running.
co_ltext ?= co_ext_objects->get_ext_buffered_object(
                                  co_ltext_class_id ).
firstly, what does "?=" mean?
secondly, if i go to get_ext_buffered_object, i find the following code.
ro_object = co_ext_objects->get_ext_buffered_object( io_id ).
how/where is the code running to fill the initial co_ltext field?
please and thank you.

thanks for the quick reply. i think i understand the down cast function.
when i debug the code at the point of the following:
co_ltext ?= co_ext_objects->get_ext_buffered_object(
                                  co_ltext_class_id ).
it goes to the get_ext_buffered_object method, and i see the following:
data:
    ls_ext_object type t_ext_object.
read table ct_external_objects into ls_ext_object
    with table key id = io_id.
ro_object = ls_ext_object-object.
can you easily tell me how the ct_external_objects table is populated? i know that the table is in another class "CL_WTY_BUFFER_EXT_CNTL" and it is a attribute of that class, but i do not know how it is populated. do you have another link to show me a easy way to determine how a table is populated?
the issue i am having is that this table does not always have the text info i am looking for. i would like to review their code to see if it is a data problem, or a code problem.
thanks again.

Regarding SAP ABAP OOPS

Hi ALL,
Could anybody give some oops concepts in ABAP with examples.
Thanks & Regards

Just take case if you want to access element from node in context ...such code by wizard Appears ....
DATA:
zobj_bbp_ior_util TYPE REF TO zcl_bbp_ior_util,
node_ztiornode TYPE REF TO if_wd_context_node,
elem_ztiornode TYPE REF TO if_wd_context_element,
stru_ztiornode TYPE zsior.
navigate from <CONTEXT> to <ZTIORNODE> via lead selection
node_ztiornode = wd_context->get_child_node( name = if_request_ior=>wdctx_ztiornode ).
get element via lead selection
elem_ztiornode = node_ztiornode->get_element( 1 ).

WebDynpro for ABAP Vs Java

Hi all,
I have recently started learning Web Dynpro for ABAP.
I have worked in WebDynpro for Java.
1)I wanted to understand pros and cons of WebDynpro for ABAP and Java.
2)What are the functionality that are available in Web Dynpro for Java but not in Web Dynpro for ABAP.
3)What should be preferred when considering performance issues - WD for ABAP of Java?
Any Web Log or Link in this context will be helpful.
Thanks a lot,
Rashmi

Hi,
OOPs ABAP uses Classes and Interfaces which uses Methods and events.
If you have Java skills it is advantage for you.
There are Local classes as well as Global Classes.
Local classes we can work in SE38 straight away.
But mostly it is better to use the Global classes.
Global Classes or Interfaces are to be created in SE24.
SAP already given some predefined classes and Interfaces.
This OOPS concepts very useful for writing BADI's also.
So first create a class in SE 24.
Define attributes, Methods for that class.
Define parameters for that Method.
You can define event handlers also to handle the messages.
After creation in each method write the code.
Methods are similar to ABAP PERFORM -FORM statements.
After the creation of CLass and methods come to SE38 and create the program.
In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
see the links below, Understand them and start developing.
chk out the links below:

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
Bikas

Normal 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.

ABAP exceptions!

Hi!
 Pls tell me a sample code in core abap exception handling
 ie using raise etc...
 one more thing
 we can use this try endtry catch endcatch etc without using oops concept in abap.
will it works
looking for your reply.

Hi,
Exceptions are situations that occur while an ABAP program is being executed, in which normal continuation of the program does not make any sense.
Exceptions can be raised either implicitly in the ABAP runtime environment or explicitly in the ABAP program.
For example, division by zero leads to an exception in the ABAP runtime environment. It is possible to determine this situation through a query in the ABAP program and to trigger an exception there.
See the demo program DEMO_HANDLE_EXCEPTIONS in se38.
*--EXAMPLE FOR RUNTIME ERROR--
*DATA : VALUE1 TYPE I.
*VALUE1 = 1 / 0. "----
>>>>>> IT MAKES RUN TIME ERROR.
*WRITE : VALUE1.
*--EXAMPLE FOR HOW TO CATCH THE ARITHMETIC ERROR AT THE RUN TIME USING SUBRC--
*DATA : VALUE1 TYPE I.
*CATCH SYSTEM-EXCEPTIONS ARITHMETIC_ERRORS = 1.
*VALUE1 = 1 / 0.
*WRITE : VALUE1.
*ENDCATCH.
*IF SY-SUBRC = 1.
*WRITE : ' IT MAKES ERROR'.
*ELSE.
*WRITE : VALUE1.
*ENDIF.
in abap program we handle exceptions based on value returned by the system variable SY-SUBRC.
if SY-SUBRC = 0.
means execution completed sucessfull.
if SY-SUBRC = 1........n.
means execution compleated not sucessfully.
if sy-sbrc = 0.
write:/ 'execution sucessfull.
**here write logic as per u r requirement
else sy-subrc = '1'
message
elseif sy-subrc eq '2'
message
elseif sy-subrc eq '3'
message
elseif sy-subrc eq '4'
message
endif
Messages are defined in SE91..
These messages are of 5 types..
A Termination Message
The message appears in a dialog box, and the program terminates. When the user has confirmed the message, control returns to the next-highest area menu.
E Error Message
Depending on the program context, an error dialog appears or the program terminates.
I (Information)
The message appears in a dialog box. Once the user has confirmed the message, the program continues immediately after the MESSAGE statement.
S (Status Message)
The program continues normally after the MESSAGE statement, and the message is displayed in the status bar of the next screen.
W (Warning)
Depending on the program context, an error dialog appears or the program terminates.
X (Exit)
No message is displayed, and the program terminates with a short dump. Program terminations with a short dump normally only occur when a runtime error occurs. Message type X allows you to force a program termination. The short dump contains the message ID.

Oops programming

hi,friends
does anybody working on ABAP OBJECTS?
so what r the diffrent programs ur writing using oops approach in ABAP? i mean reports......like that....
plz explain something ur working on ABAP OBJECTS..in real time....

Hi Prashanth
You use OOPS for the following advantages.
Complex software systems become easier to understand, since object-oriented structuring provides a closer representation of reality than other programming techniques.
In a well-designed object-oriented system, it should be possible to implement changes at class level, without having to make alterations at other points in the system. This reduces the overall amount of maintenance required.
Through polymorphism and inheritance, object-oriented programming allows you to reuse individual components.
In an object-oriented system, the amount of work involved in revising and maintaining the system is reduced, since many problems can be detected and corrected in the design phase.
You will releaze OOPS advantage only if you involve in complex projects.
For reading in ABAP OOPS concepts, refer the below links.

Need a ebook or some explanation and tutorial on OOP

Hi experts,
I'm new to OOP in SAP ABAP. Does anyone have some copy of tutorials, explanation and ebooks on OOP? I badly need it to finish my work in office.. Please... thanks in advance!

Hi,
The following lines explain the main Abap object oriented concepts that differs from traditional abap.
Introduction
The object orientation can be defined as a problem-solving method in which the software solution reflects objects in the real world. Therefore, a comprehensive introduction to object orientation would go far beyond the limits of this introduction to ABAP Objects as a whole.
Object
An object can be defined as a section of source code that contains data and provides services. The attributes of the object are formed by the data. The services are known as methods (also known as operations or functions). Typically, it is seen that the methods operate on private data (the attributes, or state of the object), which is only visible to the methods of the object. Thus, the attributes of an object cannot be changed directly by the user, but by the methods of the object only. This guarantees the internal consistency of the object.
Classes
The classes are very important, as they describe the objects. From a technical point of view, the objects are runtime instances of a class. One can create any number of objects based on a single class in theory. Each instance (object) of a class has a unique identity and its own set of values for its attributes.
Features of Object Orientation
Encapsulation
According to this property, objects restrict the visibility of their resources (attributes and methods) to other users. Every object has an interface which plays a very important role. It determines how other objects can interact with it. It is found that the implementation of the object is encapsulated, which means that it is invisible outside the object itself.
Polymorphism
According to this property, identical (identically-named) methods behave differently in different classes. Object-oriented programming contains constructions, which are called interfaces. They enable you to address methods with the same name in different objects. The implementation of the method is specific to a particular class, though the form of address is always the same.
Inheritance
According to this property, one can use an existing class to derive a new class. The data and methods of the super class are inherited by the derived classes. However, they can overwrite existing methods and add new ones.
Uses of Object Orientation
The object-oriented programming is quite useful in many ways. It has various advantages, some of which are mentioned below.
Since object-oriented structuring provides a closer representation of reality than other programming techniques, complex software systems become easier to understand.
In object-oriented system, it should be possible to implement changes at class level, without having to make alterations at other points in the system. This reduces the overall amount of maintenance required.
The object-oriented programming allows reusing individual components through polymorphism and inheritance.
In this system, the amount of work involved in revising and maintaining the system is reduced as many problems can be detected and corrected in the design phase.
To achieve these goals, the followings are required:
Object-oriented programming languages: The efficiency of object-oriented programming depends directly on how object-oriented language techniques are implemented in the system kernel.
Object-oriented tools: Object-oriented tools allow you to create object-oriented programs in object Oriented languages. They also allow you to model and store development objects and the Relationships between them.
Object-oriented modeling: The object-orientation modeling of a software system is the most important, most time-consuming, and most difficult requirement for attaining the above goals. These designs involve more than just object-oriented programming and logical advantages that are independent of the actual implementation are provided by it.
ABAP Objects
ABAP Objects is a new concept in R/3 System and you can find its two distinct meanings --- one is for the entire ABAP runtime environment and the other represents the new object-oriented generation of this language.
The Runtime Environment
ABAP Objects, for the entire ABAP runtime environment, are an indication of how SAP has, for sometime, been moving towards object orientation. Object-oriented techniques have been used exclusively in system design. The ABAP language did not support these techniques earlier.
The ABAP Workbench will allow creating R/3 Repository objects in this regard. These objects are programs, authorization objects, lock objects, customizing objects, and so on and so forth. By using function modules, one can also encapsulate functions in separate programs with a defined lnterface. The Business Object Repository (BOR) allows you to create SAP Business Objects for internal and external use.
The Object-Oriented Language Extension
ABAP Objects support object-oriented programming. The ABAP Objects is a complete set of object-oriented statements, which has been introduced into the ABAP language. This object-oriented extension of ABAP builds on the existing language and is fully compatible with it.
The Object Orientation (OO), also known as the object-oriented paradigm, is a programming model that unites data and functions in objects. You can not only use ABAP Objects in existing programs, but also work with and use a conventional ABAP in new ABAP Objects programs. The rest of the ABAP language is primarily intended for structured programming, where data is stored in a structured form in database tables and function-oriented programs access and work with it.
Moreover, we should know that the object-oriented enhancement of ABAP is based on the models of Java and C++. It is compatible with external object interfaces such as DCOM and CORBA. The implementation of object-oriented elements in the kernel of the ABAP language has considerably increased response times when you work with ABAP Objects. Some other objects, such as SAP Business Objects and GUI objects, which are already object-oriented by themselves, are also benefiting from being incorporated into ABAP Objects.
About Classes
The classes are templates for objects. An abstract description of an object is the class. You could say 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.
Local and Global Classes
In ABAP Objects, classes can be declared either globally or locally. You define global classes and interfaces in the Class Builder (Transaction SE24.} in the ABAP Workbench. In the R/3 Repository, they are stored centrally in class pools in the class library. In an R/3 System, all of the ABAP programs can access the global classes. The 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, then it looks for a global class. Apart from the visibility question, there is no difference between using a global class and using a local class.
However, there is 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, then to define the outwardly visible components so that it fits into that program is usually sufficient. On the other hand, global classes must be able to be used anywhere. Since the system must be able to guarantee any program using an object of a global class, it can recognize the data type of each interface parameter and then certain restrictions are applied at the time of defining the interface of a global class.
Defining Local Classes
Local classes consist of ABAP source code, where the ABAP statements CLASS...ENDCLASS are enclosed. A complete class definition consists of the following parts, a declaration part and, if required, an implementation part. It is found that the declaration part of a class . The new class is called the subclass of the class from which it is derived. The original class is called the superclass of the new class. It contains the same components as the superclass if you do not add any new declarations to the subclass. However, in the subclass only the public and protected components of the superclass are visible. The private components of the superclass are not visible though they exist in the subclass. You can declare private components in a subclass that have the same names as private components of the superclass. It is seen that each class works with its own private components. The another point that we note is that methods which a subclass inherits from a superclass use the private attributes of the superclass and not any private components of the subclass with the same names.
The subclass is an exact replica of the superclass if the superclass does not have any private visibility section. However, you can add a new component to the subclass because it allows you to turn the subclass into a specialized version of the superclass. If a subclass is itself the superclass of further classes, then you can introduce a new level of specialization.
Polymorphism
Reference variables are defined with reference to a superclass or an interface defined with reference to it can also contain references to any of its subclasses. A reference variable defined with reference to a superclass or an interface implemented by a superclass can contain references to instances of any of its subclasses, since subclasses contain all of the components of all of their superclasses and also convey that the interfaces of methods cannot be changed. In particular, you can define the target variable with reference to the generic class OBJECT.
Using the CREATE OBJECT statement, when you create an object and a reference variable typed with reference to a subclass then you can use the TY PE addition to which the reference in the reference variable will point.
A reference variable can be used by a static user to address the components visible to it in the superclass to which the reference variable refers. However, any specialization implemented in the subclass cannot be addressed by it.
Depending on the position in the inheritance tree at which the referenced object occurs, you can use a single reference variable to call different implementations of the method. This is possible only if you redefine an instance method in one or more subclasses. This concept is called polymorphism, in which different classes can have the same interface and, therefore, be addressed using reference variables with a single type.
Conclusion
I have explained object orientation which is such an important aspect in SAP. The discussion began with the features of Object Orientation and includes the runtime environment, the language extension, the classes and the class components. Apart from that I have also discussed for new first time readers event handling, inheritance encapsulation and polymorphism.

Parameter mapping
normal 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.
