This is about abap objects

hi,
there is perform in normal abap program i have convert it into object oriented program we can write in call method but how to write the stmt in object oriented programing
perform abb (sapmov101) or perform asd in program sapmov101
think sapmov101 is module pool program.
how to convert to
call method
is it posible to have program parameter in object oriented programing .

Hi,
You have to define a class in Se24 and methods for that class
You can define some parameters for that method.
define a object type ref to class
call the method with the parameters..
something like below
CALL METHOD im_header->get_data
RECEIVING
re_data = re_data.
reward if useful

About ABAP Object

Hello All,
i have some question about ABAP Object.
What is the meaning of friend class and singleton?
Regards,
Luke

Hi,
The addition Friends makes class class a friend of classes classi and or interfaces ifaci.At the sam time, all subclasses of classes classi, all classes that implement one of the interfaces ifaci and all interfaces that have one of the interfaces ifaci as a component interface become friends of class. you have to specify at least one class or interface.
The friends of a class have unrestricted access to the protected and private components of that class, and can generate unrestricted instances of the class.
The friends of class are not automatically friends of subclasses of class. the addition Friends does not make class a friend of its friends.
Thea ddition global is allowed only when you use the addition public for the global class of a class pool at the same time.You can list other global classes and interfaces from the class library after global friends.This addition is generated when the Class Builder creates a global class and you specified friends at the corresponding tab page of the class Builder.
`
In the example , classs c2 is a friend of interface i1, and therefore also of the implementing class c1. It can instantiate these objects and access their private component a1.
interface i1.
endinterface.
class c1 definition create private friends i1.
private section.
data a1(10) type c value 'Class 1'.
endclass.
class c2 definition.
public section.
interfaces i1.
methods m2.
endclass.
class c2 implementation.
method m2.
data oref type ref to c1.
create object oref.
write oref->a1.
endmethod.
enclass.

About ABAP OBJECTS

Hi Experts,
Can anybody suggest documentation on ABAP OBJECTS....its great helpful to me.....
Thanks
Venkat

HI,
OBJECT:
An object is a section of source code that contains data and provides services. The data forms the attributes of the object. The services are known as methods (also known as operations or functions). Typically, methods operate on private data (the attributes, or state of the object), which is only visible to the methods of the object.
What are ABAP Objects?
1) ABAP Objects is a new concept in R/3 Release 4.0. The term has two meanings. On the one hand, it stands for the entire ABAP runtime environment. On the other hand, it represents the object-oriented extension of the ABAP language.
2) The new name ABAP Objects for the entire ABAP runtime environment is an indication of the way in which SAP has, for some time, been moving towards object orientation, and of its commitment to pursuing this line further.
3) The ABAP Workbench allows you to create R/3 Repository objects such as programs, authorization objects, lock objects, Customizing objects, and so on.
4) Using function modules, you can encapsulate functions in separate programs with a defined interface. The Business Object Repository (BOR) allows you to create SAP Business Objects for internal and external use (DCOM/CORBA).
Just have a look at these links:

See this question about static object

1)static A a =new A();
2) A a1=new A();
what is the difference between them?

static A a =new A();
When this line is written in another class say : class b;
a is accessible without the need for declaring an object of b.
i.e., b.a
Not in the other case.
Many factory classes and methods are accessed this way coz, the classes are private and abstract, so u cannot make an object of that class.
For example:
System.out.println() - here println() is a method, out is an object of some class that is declared static in the class System. if it were'nt static, then we had to make an object of the System class and then access the out object,
hope this helps
let me know

Overriding attributes in ABAP objects

Hello,
I currently want know if it is possible to override attributes in ABAP objects. i know it is possible with methods. I have extend a previous class functionality and want to change the refrence type of an attribute from the parent class, but only on the child. Is this possible in ABAP object or even in normal object oriented techniques.
Thanks
Brendan

Hi,
ususally you can achive this with other technics. You can e.g. use the class hierarchy for this:
The attribute is of type REF_SUPERCLASS. Within the superclass it should be working when you set subclasses of REF_SUPERCLASS as attribute.
Another way is to use interfaces as reference type for your attribute.
Please refer to [ABAP Objects|http://help.sap.com/saphelp_nw70/helpdata/EN/ce/b518b6513611d194a50000e8353423/frameset.htm]. Especially the chapters about Inheritance and Interfaces.

Abap objects standards

Hi Folks,
I'm in need of help. I have just come into a shop that has no SAP OO standards. There are many kingdoms that are not even using SE24 to build classes. Is there a SAP document or guide I can use to set standards. I am really fighting with producing good code over what is in place.
Thanks
Bruce

Hi Bruce,
I am sorry for saying things that have nothing to do with ABAP , i really thought that what i said about zevolving.com had something to do with ABAP OO, regarding design patterns and OO concepts applied to it.
See below my reason to think it: (there's much more, i really appreciate this blog and several times i merged these approaches to mine )
and etc,
I like to learn concepts, because these are made of ideas. Ideas aren't bonded to physical limitations. Your physical resources may evolve and become obsolete over time, an idea can evolve but it can't die, although it can be changed with a tremendous flexibility, it will never be obsolete over a reasonable amount of time.
I am a bit sad because you said i am hiding behind the first link i sent . Robert Martin (CEO of Object Mentor) has so much to say about this matter, and his text about Symptoms of Rotting Design says about an absurd quantity of problems i have seen and interacted with in my ABAP experience. The other book i mentioned has so much good concepts and ideas that in here ... i can't put in words.
I am really sorry for being a nuisance. Lesson learned, i won't talk about matters that are so far from the topic ever again.
Obs.: About official SAP documentation, in the SAP Official Course TAW12 (since 2007 *when i saw this subject in it), SAP released in part 1, around 300 pages of content about ABAP Objects. And there are others you can check in SAP PRESS

ABAP-Object Services

Hello Gurus,
Can you guys enlighten me about ABAP-Object services? I've been doing ABAP objects for quite some time now. I want to know all about it (ABAP-Object services). I would like to confirm if this object is similar with the one I know in .net or in JAVA that is normally called Class Libraries.
Thanks!

ABAP objects, drilling down into methods/parameter/method/parameter...

Hello all,
When creating or changing purchase orders using the enjoy transactions ME21N and ME22N, I want to force the users to have the same delivery address on every line item. I have found and activated the BADI ME_PROCESS_PO_CUST. I have added some code in method CHECK and put a breakpoint on that code. The transaction is stopping on my breakpoint. So far so good.
Parameter IM_HEADER is of type IF_PURCHASE_ORDER_MM,
that has method GET_ITEMS,
that has parameter RE_ITEMS that is a table of of type PURCHASE_ORDER_ITEMS,
method GET_DATA
with parameter RE_DATA
with fields ADRNR & ADRN2
From inside of the method CHECK of BADI, what syntax do I need to create an internal table of the line item fields that are in parameter RE_DATA of method GET_DATA? I am just starting to work with ABAP objects. Any help would be greatly appreciated.
Thanks
Bruce

Uwe, thanks for the quick response.
Your solution,
DATA: lt_items      TYPE purchase_order_items,
           ls_item       TYPE purchase_order_item.
CALL METHOD im_header->get_items
   receiving
     re_items = lt_items.
Short version:
lt_items = im_header->get_items( ).
LOOP AT lt_items INTO ls_item.
do something
ENDLOOP.
got me very close to the solution. The table lt_items contain the number of entries corresponding to the actual line items. But the data element ls_item does not contain the fields I'm expecting from:
method GET_DATA ,
parameter RE_DATA,
type MEPOITEM.
How do I populate ls_item with the 197 fields from structure MEPOITEM?
If I knew more about ABAP objects, I'm sure I could easily change the code myself. But today, I need the generosity of others to help me solve this.
Thanks
Bruce

The display rows should get greyed out. How to achieve this functionality thru ABAP objects.
Thanks

Hi Namit,
Open the particular page , and select dynamic navigation (from the right hand side corner Display drop down menu ) .
U will get all the links which r there in the detailed navigation.

ABAP objects for transfer/update rules - does this apply to include stateme

I have a question about the new requirement for the code in the update/transfer rules to be written in ABAP Objects standards. Does this still apply if in your update rules you using include programs? Does this mean that when we upgrade we will have to follow the ABAP Objects standards (ie no header lines)?

Routines will method based.
In addition to what Chetan has sent, check this how to also.

Adding leading zeros in abap objects.

Can anyone explain me
1. How to add leading zeros to a field in abap objects.
For eg:
data: dmb(6) type c value '123456',
actually the output value of c should have leading zeros added to it for length 16.
i.e '0000000000123456' . If the length of dmb is less than 16 then leading zeros should be added to that value to make it 16 as length.
Please tell me how to do it in ABAP Objects.

Hi Camila
Try to use the statement
DATA: ALPHABET(15) VALUE ' ABCDEFGHIJ',
 M1(4) VALUE 'ABCD',
 M2(6) VALUE 'BJJCA '.
SHIFT ALPHABET LEFT DELETING LEADING M1.
The field
ALPHABET
remains unchanged.
SHIFT ALPHABET LEFT DELETING LEADING SPACE.
The field ALPHABET now has the following contents:
'ABCDEFGHIJ '.
SHIFT ALPHABET RIGHT DELETING TRAILING M2.
ALPHABET now has the following contents:
' ABCDEFGHI'.
IN CHARACTER MODE
Effect
This is the default setting (see above), and the addition is therefore optional.
Note
Performance:
For performance reasons, you should avoid using SHIFT in WHILE loops.
The runtime required to shift a field with length 10 by one character to the right or left requires about 5 msn (standardized microseconds). A cyclical shift requires around 7 msn. The runtime for the ...
LEFT DELETING LEADING
... variant is around 3.5 msn, for ...
RIGHT DELETING TRAILING
... around 4.5 msn.

Poll: Development in ABAP Objects / Webdynpro vs. classical Dynpro

Hey there ABAP developers,
I just want to ask if you can give me one or two minutes of your attention for two poll questions.
At the moment I´m writing my master thesis about the development of a monitoring tool in ABAP. One of my bigger chapters is about the decision, which programming paradigm should be used for new development projects in SAP. And another important one is about WebDynpro vs. classical Dynpros.
Because of the fact, that I can´t create any polls in here, I just started this discussion and hope for many replies .
It would be very nice if some of you could give me an answer to the following questions (only 2 ), so that I can maybe use the result of this poll in my master thesis, if there are enough responses.
1. What percentage of new development projects are you developing in ABAP Objects? (Not to be considered small reports that just runs for only one time)
     A. 0 %
     B. less than 25%
     C. 25% - 49%
     D. 50% - 75%
     E. more than 75%
2. Which GUI technology do you prefer?
     A. Classical Dynpro
     B. WebDynpro
     C. Business Server Pages (BSP)
     D. others (please mention)
I want to thank you in advance for answering the questions,
Best regards,
Christoph

Hi,
Present SAP Implementation projects are very rare, maximum projects are support and up gradations only .
If they want Implement the SAP newly , defiantly they should creating ABAP Objects.
Why Because ABAP Objects are Object Oriented Concepts, so, for future reference and re usability..etc .
Now Come to the First Quetion.
if it is implementation project   ABAP Objects are 25% - 49%.
if it is Support project ABAP Objects are 25%
Now Come to the Second Quetion.
Depend upon Reqmnt, but Most of the Applications are Webdynpro . i.e 70%.
Remaining 30% All ( BSP and GUI ....Etc..)
This is my opinion.
