Hi All,
I have a simple ALV Grid Report(OOPS), I would like to give a Text for Total Row. In REUSE_ALV_GRID we have the option of giving this text, but i am not able to figure it out how to get the same in OOPS.
Regards
AnupHi Anup,
While using ALV with OOP methodology, you can create an extra row for giving the sum of any field.
In the field catalog, there is a component named 'DO_SUM', if set, will give the total value for the field.
In the method where you fill the field catalog , just add this component.
eg:
form catalog_fill changing p_field_catalog.
data ls_fcat type lvc_s_fcat .
ls_fcat-fieldname = 'CARRID' .
ls_fcat-inttype = 'C' .
ls_fcat-outputlen = '20' .
ls_fcat-coltext = 'Carrier ID' .
ls_fcat-web_field = 'carrid_handle'.
ls_fcat-edit = 'X'.
*ls_fcat-emphasize = 'C310'. "needed for column coloring
append ls_fcat to field_catalog .
clear ls_fcat .
ls_fcat-fieldname = 'FLDATE' .
ls_fcat-ref_table = 'SFLIGHT' .
ls_fcat-ref_table = 'FLDATE' .
ls_fcat-outputlen = '20' .
<b>ls_fcat-do_sum = 'X'.</b>
ls_fcat-coltext = 'Flight Date' .
ls_fcat-web_field = 'fldate_handle'.
append ls_fcat to field_catalog .
clear ls_fcat .
ls_fcat-fieldname = 'PRICE' .
ls_fcat-ref_table = 'SFLIGHT' .
ls_fcat-ref_table = 'PRICE' .
ls_fcat-outputlen = '20' .
ls_fcat-coltext = 'Airfare' .
append ls_fcat to field_catalog .
endform.
In this way, you can get the total of any field in ALV.

Best Practice??? Change from internal boot disk to external disk
I have a mini running 10.5.6 server and it currently boots off it's internal disk. I was hoping to get some feedback/input from others on a good process to convert the system from it's internal boot disk to an external boot disk (firewire).
I wanted minimum downtime during the conversion and I of course, want a complete snapshot on the new boot disk. Lastly, I do not have a local keyboard and console on the system although I could connect one if it seemed to be much easier that way.
In general, I am thinking of the following:
1) Boot into the Leopard Server CD.
2) Use diskutility to Restore from the internal boot disk to the new external boot disk.
3) Choose the new boot disk as the startup disk.
4) Reboot onto new disk.
Is diskutility the best bet?? Meaning will it work this way if the drives are different sizes??
Should I try to clone the disk from the internal boot disk (assuming I shutoff services first) using SuperDuper or Carbon Copy Cloner?? But I believe they do not copy over all logfiles, etc..
Or does anyone have a quick overview of a methodology which they have done in the past or just are suggesting might be a better process than the ones I described??
In Summary:
1) From the CD, clone using diskutil and change boot disk
2) From the running OS, clone using SuperDuper or CCC and than reboot onto new disk
3) Something else??
Thank you in advance.For cloning the machine you have the approach fine. Disk Utility is fine and booting from the CD is the best method. Simply use the restore method.
But why on earth would you want to boot from an external Firewire drive? First, there is the issue of speed. You have a mini, let's assume it is a one generation back Intel. It has an internal SATA drive on a 1.5 Gbps connection. You want to move that to a 400 Mbps Firewire bus? Next, beyond the speed issues, you have a persistence issue. You are taking the boot volume and moving into to a transitory bus. One of Firewire's greatest strengths is easy connection/disconnection. Persistence is not a strong point.
Next, if your plan is to move the boot volume to some form of a Firewire RAID, then you are even penalizing yourself more. The mini has one FireWire port. If you are using two devices and creating a mirror RAID, then you need to daisy chain. Talk about points of failure, asynchronous startup time, bus blocking, etc. Not wise.
Plus, I can not count how many external firewire devices have burnt up in the effort to have small footprints. Lacie and the "let's put a drive in a metal case with no fan" approach = melted drive. Western Digital and Lacie with the "let's make a completely un-reusable external power brick that either breaks in a small breeze or falls out when the heavy guy walks by the server" approach.
If you are looking at a Firewire RAID enclosure, then you are missing the objective of speed as you are limited by the 400 bus. It is nice to say that you have a four drive SATA 2 RAID case running a RAID 5, but you are defeating the purpose of why you bought the raid. The RAID 5 can provide an exponential increase in I/O performance. But that goes out the window because of the slow bus.
If your argument is that "this is a server and my bottleneck is Ethernet," that too does not hold up. You are likely running on a gigabyte network.
For system details check out http://developer.apple.com/documentation/HardwareDrivers/Conceptual/Macmini_0602 /Articles/architecture.html.
Take this with a grain of salt. You caught me on a grumpy day as yesterday I dealt with a melted external firewire drive.
My advice is buy real server class hardware. What is you objective? Drive redundancy? Capacity? A mini is a great dev server. Not a production server. This is your data. Presumably the data that makes your business function. Don't trust it to a single platter. And don't trust it to a consumer level, disposable system. I am not trying to malign the mini. It is a fine machine for its role. Its role however is not to be a production file server. Now as a web server, we are talking a different situation.
Ok, I am rambling. Hope this helps in some way. -
hi all,
I have an overflow error in alv total field.
first i filled alv grid using et_table_for_first_display, again i changed itab data
and use refresh_table_display to refresh data.
the alv contains total fields in field catalog.... when i try to 'refresh_table_display '
it comes an over flow error is coming and it comes every sort of records.. how can i trap this error ..??

How to learn technics in wrting class, objects and methods
Hi ,
I am new this oops methodology. I know java language but don't know the basics. I mean to say I have no idea how to write classes and methods. I can write one single class with all the methods and I can call that class from an another class but this is not the way... I knew it but I am kinda confuse how to write the well structured oops style classes and methods....
Can anybody help me please........
ThanksA short simple (overly simple) explanation is that objects are like little machines, which operate independantly from other objects (other little machines). You design an application as a collection of these little machine/objects, interacting with each other. Then you drill down another layer of detail, and design the machines themselves. You do this by defining the classes, which are like blueprints to make a little machine/object.
In java, this is largely expressed by the interface definition at the higher level, and the class definition at the lower level. The interfaces say how various objects may talk to each other, and the class definitions say how any individual object may talk at all.
This is a very basic description, and in fact isn't entirely accurate; if they want to lots of people on this forum could pick it apart. But hopefully it gets the idea across. (As my language design prof said, quoting somebody else, "teaching is just a series of lies.")
There are resources on the web about object-oriented programming, object-oriented design, etc. mutmansky's right, a college course is best, but you can still learn a lot from docs on the web. -
Feature Request: Class Editor - Allow method code.
Hi jDev team, and keep up the wonderful work.
It seems to me that with a minor enhancement (in terms of technical complexity) to the class editor, a major functional achievement can be accomplished.
Within the class editor give us the ability to actually code/edit/maintain the methods. This, would not only enhance the useability of the class editor, but would also open the absolute possibility of custom coding a complete java file without the use of the editor. This coding style (simply maintaining methods) blends very nicely with oop methodology. With the ability to also maintain javadoc details on our classes and methods from within the class editor, why ever use ancient code editors?
I think, marketing would like the idea as well.
Please let me know what you think. Thanks.
-NatCorrect.
Preferably, while 'walking the list' of method names, the contents (between the braces) of that method should be viewable/editable in another open panel.
While at it, please supply the same support of inner classes as well, and voila, you almost don't need the editor!
Thanks

Which group of programming languages to master?
Which group of programming languages should I master to tackle a diverse set of problems? I would like for this list to be small as to not learn too many languages while not having a good grasp on them. The purpose of this is so I can approach any problem and pick the right tool for the job.
Right now I'm thinking about C and Fortran for computational problems requiring speed (fortran because I'm a science student), Python for quick scripting and when development time is the most crucial factor, and Haskell for a functional middle ground. I appreciate any feedback.

Yes, I know that. I guess the question I should have asked is which categories of languages are appropriate to which problems? Then I could pick one of each category and learn them.
Basu wrote:
I mostly second with whatever austin.rbn says but with some additions:
1. You should learn C because it will make you learn how the machine actually works. Do not conflate C with C++, they are pretty different languages.
2. You should learn a UNIX-y scripting language -- one of Perl/Python/Ruby for quick prototyping, string mangling, web dev, etc.
3. You should learn an enterprise-y object oriented programming language such as C++, C# or Java
4. You should learn a strongly typed functional programming language to better understand the mathematical basis of computer science like ML, OCaml or Haskell
5. You should learn a Lisp dialect such as Scheme or Common Lisp (I would recommend the Racket implementation of Scheme).
Let me know if you have any questions.
Although pling may disagree with some of the reasons, these seem like sensible categories. What are some of the advantages of learning a Lisp language, and what domain would it be advantageous over other languages?

You may also want to ask yourself if you will ever need to run your codes in a distributed computing environment; e.g. a Linux cluster. If yes, then there is a high probability that you'll need to learn MPI. I know that most MPI implementations provide Fortran, C, and C++ API's, and there are also some Python wrappers out there as well (e.g. mpi4py).
I should also point out that most Fortran, C, and C++ compilers support OpenMP out of the box. This means that a code that was initially written in Fortran, C, or C++ can be modified (usually rather easily) to take advantage of multi-core processors.
As you might be aware, GPGPU computing is becoming more popular within the scientific community. Most of the GPGPU languages are minor extensions of the C language (and in some cases just additional C libraries). So, I suppose if you start out developing in C, then learning one of the GPGPU languages would seem like a natural extension of what you already know.
(As others have alluded, you may want to view all of this as a never ending evolutionary process. That is, don't worry about finding some panacea to all your future programming needs today. Focus on learning the principles, keep and open mind, and be ready to adapt to an ever changing environment. Whatever the answers you get today, 10 years from now the answers will likely be very different.)
Yes, I will eventually need to work with distributed computer systems and maybe GPU programming such as CUDA. For this purpose, where speed is critical, I would need to have C mastered. However I'm very used to the OOP methodology of Java and C++ and haven't been able to wrap my head around doing things otherwise. So as pling mentioned, I need to be able to first do procedural algorithms well and I think I need to learn C from the ground up. What I know of C, I've learned through C++. What is an introductory book that you would recommend to do this?
pling wrote:Do what a pro and would do and code in the highly productive scripting language until you a performance hit, then write C code for that limited area. Rather than learning lots of languages badly, learn the fundamentals of procedural programming well - get books like Code Complete, Pragmatic Programming, Programming Perls, etc and work through them.
Are C and python sufficient for general purpose programming? Are there any cases where it is difficult in getting the resultant amalgamated program to run smoothly? (just a wild guess)

Sub total in ALV GRID using oops concept
Hi,
If Plant (VBAP-WERKS) is not the same for all items on a Sales Order (VBAK-VBELN is the same for al items) then create a separate line on the report for each different plant specified in the line items. Copy all fields from the original order line except for plant and Net Value. Net Value should be the total of item Net Values for all items with the same plant in the order.
Example:
Data:
Order---- Item- Plant- Net Value---
123---- 010- 3467- 100.00---
123---- 020- 7865- 50.00---
123---- 030- 3467- 80.50---
Report:
Order- Plant- Net Value---
123- 3467- 180.50---
123- 7865- 50.00----
I need to dispaly the Report format in ALV Grid using oops concept...
no need of calling any function modules.
Regards,
NithyaHi
Here is example code
This is the method to be called:
get_subtotals
Use
Returns the current subtotals of the ALV Grid Control. Having created totals for at least one column, users can calculate at most nine subtotals. The list is sorted by the values of one or several columns (called the subtotals column). If a value is changed in the subtotals column, the subtotal is displayed (this is also referred to as control level change).
Integration
Before you access the subtotals value, you use the method get_sort_criteria to get the sort table . One row of this table describes properties of a column in the output table.
If the field SUBTOT is set for a column in this table, the column is a subtotals column.
The field SPOS then indicates at which level (see below) the subtotal has been calculated.
The field FIELDNAME contains the name of the subtotals column in the output table.
Based on this information, you specifically access the values of the tables passed (using reference variables COLLECT01 to COLLECT09).
Features
CALL METHOD <ref. var. to CL_GUI_ALV_GRID>->get_subtotals
IMPORTING
EP_COLLECT00 = <reference variable of type REF TO DATA>
EP_COLLECT01 = <reference variable of type REF TO DATA>
EP_COLLECT02 = <reference variable of type REF TO DATA>
EP_COLLECT03 = <reference variable of type REF TO DATA>
EP_COLLECT04 = <reference variable of type REF TO DATA>
EP_COLLECT05 = <reference variable of type REF TO DATA>
EP_COLLECT06 = <reference variable of type REF TO DATA>
EP_COLLECT07 = <reference variable of type REF TO DATA>
EP_COLLECT08 = <reference variable of type REF TO DATA>
EP_COLLECT09 = <reference variable of type REF TO DATA>
ET_GROUPLEVELS = <ínternal table of type LVC_T_GRPL>.
In order to access the values of EP_COLLECT00 to EP_COLLECT09, you use ASSIGN to dereference the relevant reference variable in a field symbol of your output table type (see below).
Parameters
Meaning
EP_COLLECT00
Points to the totals line. Since there is only one totals line which, in addition, has a unique totalling area, no further information is available for this table in table ET_GROUPLEVELS.
get_subtotals
EP_COLLECT01 to EP_COLLECT09
Point to the subtotals line. For each subtotals level, there is one reference variable. Each of these variables points to an internal table that has the type of the output table. EP_COLLECT01 points to the subtotal at the hightest level, while EP_COLLECT02 points to the subtotal at the second highest level, and so on. The levels are derived from the sort priority (field SPOS in the sort table ). The column by which the data was sorted first, is the highest subtotals level.
ET_GROUPLEVELS
Manages all indexes for the individual control levels. The fields of the table have the following meaning:
INDEX_FROM, INDEX_TO: Rows of the output table for which the subtotal was created
LEVEL: Subtotals level (see above)
COUNTER: Number of rows for which the subtotal was created
COMPRESS: For this subtotals line, the user has hidden the associated rows.
COLLECT: Indicates the subtotals table (01-09) in which the values are stored

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 <b>Giving</b> 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.
<b>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</b>.
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.
<b>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.</b>
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

I was perusing the Wikipedia entry for OOP and looking at a few of the criticism links. To me the arguments aer based on things that OOP supposedly says but that I don't really consider OOP.
http://en.wikipedia.org/wiki/Object_oriented_programming#Criticism
Perhaps they misunderstand OOP. Perhaps I'm not using OOP but rather some sort of bastardized hybrid. I do think that what I consider OO is not what I've read about or seen described in a lot of places. I've been influenced by the Interface concept such that I only consider OO concepts important at key 'gateways' or communication points in the program. Behind the scenes, (e.g. implementation classes) I have no problem violating OO principles because it's not part of the public API.
Those of you who feel you have used OO to it's fullest potential: do you think OO is an effective way to program? Do you think pure OO (as an academic might describe it) is realistic?Nobody understands OO.
Relational databases had E. F. Codd, who defined the field with his articles back in the 1970's. So now there isn't any argument about whether a database system is relational or not.
Whereas OO didn't have that foundation. So dozens of people have thrown out principles that they say are part of OO. That makes it easy for people to argue about whether something is or isn't OO. As the first link in that Criticisms section says, "The lack of consistency in OO methodologies and definitions makes it nearly impossible to make any statement about OO that all OO practitioners will agree with." Of course not all OO practitioners would agree with that.
So instead of Codd, you have codswallop.
I've been writing business programs for 30 years now. And looking back on the 25 years where I knew nothing about OO, I see hardly anything where OO would have made any difference. When you're dealing with customers and inventory and taxes where all the data is in SQL databases, OO isn't particularly helpful and when you try to use it, it just gets in the way. (Our systems aren't written in COBOL but I'm indirectly supporting Duffy's sarcastic comment here.)
That's not to say OO has no place in our business. We do have places where heterogeneous things are happening and we don't need to put them in rectangular boxes, and for those things OO is extremely useful. We have business partners sending us data in various forms through various channels and various things have to be done to that data before it's put into the rectangular boxes. That's where you can make use of the levels of abstraction that OO provides, and we've had a lot of success using it there.
But pure OO? Not in our business. -
Hi all,
I have to do a business study for an implementation project,,, can anyone tell me where can i get the details of ASAP methodology.

urendra
[email protected]Dear Urendra,
AcceleratedSAP (ASAP) is SAP's standard implementation methodology. It contains the Roadmap, a step-by-step guide that incorporates experience from many years of implementing R/3. Along with that, AcceleratedSAP contains a multitude of tools, accelerators and useful information to assist all team members in implementing R/3. Quality checks are incorporated at the end of each phase to easily monitor deliverables and critical success factors. ASAP is delivered as a PC-based package, so that - if required - an implementation project can begin prior to having an R/3 System installed.
AcceleratedSAP (ASAP): A comprehensive solution for the introduction of the R/3 System in your enterprise. ASAP and most of its tools can be used independently of an R/3 installation.
The tools available for AcceleratedSAP are:
The <b>Project Estimator</b>, an internal SAP tool which enables SAP consultants to accurately gauge the required resources, the costs and the time frame of implementation. The Project Estimator takes into account the project scope and several project and risk factors.
The <b>Concept Check Tool</b>, a tool enabling you to carry out quality checks on the project preparation, technical infrastructure and R/3 configuration settings. This is done mainly during the first two implementation phases of the R/3 project. In this way you are alerted to potential data volume and configuration conflicts that could lead to performance issues if not addressed.
The <b>Implementation Assistant</b>: The ASAP navigation tool that accompanies you through the five phases of implementation down to the task level. It includes a description and a detailed "how-to" for each task in the Roadmap. Along with that, many tools, templates and documents are hyperlinked to the task. The Implementation Assistant contains the following elements:
<b>ASAP Implementation Roadmap</b> and <b>Project Plan</b>. The Roadmap contains the five phases, from which you can drill down into work packages, activities and tasks. The Project Plan contains three components, a budget plan, a resource plan and a work plan. These are explained in more detail in the next chapter.
The ASAP Roadmap is the successor of the R/3-based Procedure Model, which was used until Rel. 3.1 in R/3 implementation projects.
<b>Knowledge Corner</b>, containing tips and tricks for configuration from consultants, detailed documentation on SAPs implementation services, information on technical tools, as well as simplification guidebooks and R/3 Customizing wizards.
<b>Question and Answer Database (Q&Adb)</b>. Using the R/3 Reference Model structure, the Q&Adb is used to assist in gathering requirements for business processes, conversions, reports, interfaces, enhancements and authorizations. The database provides useful questionnaires to help you define the process needs and also serves as a repository for all this information. Since it is a database, it allows for flexible reporting.

Advantages of OOPs over conventional prog
Dear all,
can any one explain briefly why to use OOPs concept over Conventional prog in ABAP language.
Thanks & Regards
Venkata PrasadHello Venkata,
<b>Procedural language drawback</b>
1 Program maintenance
2 Difficulty in program management as program size increases
3. Data hiding
4. Very difficult to model real world entity
5. Lack of extensibility
<b>Procedure oriented approach</b>
1. Emphasis on tasks
2. Large programs are divided into smaller programs known as functions
3. Most of the functions share global data
4. Data move openly around the system from function to function
<b>Object oriented approach</b>
Emphasis on things that does those tasks
Programs are divided into objects
3. Data structures are designed such that they characterized the objects
4. Functions that operate on the data of an object are tied together in the data structure
5. Data can be hidden and cannot be accessed by external functions
6. New data and functions can be easily added whenever necessary
<b>Object Oriented Approach (key features)</b>
1. Better Programming Structure
2. Real world entity can be modeled very well
3.stress on data security and access
4. data encapsulation and abstraction
5. Reduction in code redundancy
<b>
Why do we need oop for ABAP ???</b>
1 To be at par with the others as this is better methodology
2. To understand the recent concept of ABAP ,such as BAPI BADI WORKFLOW etc.
3. For integration of ABAP with Microsoft Technologies and JAVA as these are build on OOP concept
4. To exploit the class resources that has been provided by
SAP
<b>Reward points if helpful</b>
Thanks,
Sachin -

Hi
What is Object Orientation?
In the past, information systems used to be defined primarily by their functionality: data and functions were kept separate and linked together by means of input and output relations.
The object-oriented approach, however, focuses on objects that represent abstract or concrete things of the real world. These objects are first defined by their character and their properties which are represented by their internal structure and their attributes (data). The behaviour of these objects is described by methods (functionality).
Objects form a capsule which combines the character to the respective behaviour. Objects should enable programmers to map a real problem and its proposed software solution on a one-to-one basis.
Typical objects in a business environment are, for example, Customer, Order, or Invoice. From Release 3.1 onwards, the Business Object Repository (BOR) of SAP Web Applicaton Server ABAP has contained examples of such objects. The BOR object model will be integrated into ABAP Objects in the next Release by migrating the BOR object types to the ABAP class library.
A comprehensive introduction to object orientation as a whole would go far beyond the limits of this introduction to ABAP Objects. This documentation introduces a selection of terms that are used universally in object orientation and also occur in ABAP Objects. In subsequent sections, it goes on to discuss in more detail how these terms are used in ABAP Objects. The end of this section contains a list of further reading, with a selection of titles about object orientation.
Objects
Objects are instances of classes. They contain 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. Thus the attributes of an object cannot be changed directly by the user, but only by the methods of the object. This guarantees the internal consistency of the object.
Classes
Classes describe objects. From a technical point of view, objects are runtime instances of a class. In theory, you can create any number of objects based on a single class. Each instance (object) of a class has a unique identity and its own set of values for its attributes.
Object References
In a program, you identify and address objects using unique object references. Object references allow you to access the attributes and methods of an object.
In object-oriented programming, objects usually have the following properties:
Encapsulation
Objects restrict the visibility of their resources (attributes and methods) to other users. Every object has an interface, which determines how other objects can interact with it. The implementation of the object is encapsulated, that is, invisible outside the object itself.
Inheritance
You can use an existing class to derive a new class. Derived classes inherit the data and methods of the superclass. However, they can overwrite existing methods, and also add new ones.
Polymorphism
Identical (identically-named) methods behave differently in different classes. In ABAP Objects, polymorphism is implemented by redefining methods during inheritance and by using constructs called interfaces.
Uses of Object Orientation
Below are some of the advantages of object-oriented programming:
· 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.
Achieving these goals requires:
· Object-oriented programming languages
Object-oriented programming techniques do not necessarily depend on object-oriented programming languages. However, 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 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. Object-oriented design involves more than just object-oriented programming, and provides logical advantages that are independent of the actual implementation.
This section of the ABAP Users Guide provides an overview of the object-oriented extension of the ABAP language. We have used simple examples to demonstrate how to use the new features. However, these are not intended to be a model for object-oriented design. More detailed information about each of the ABAP Objects statements is contained in the keyword documentation in the ABAP Editor. For a comprehensive introduction to object-oriented software development, you should read one or more of the titles listed below.
ABAP supports a hybrid programming model. You can use an object-oriented ("OO") programming model based on classes and interfaces, and you can use the more classic procedural and event-driven programming model based on function modules, subroutines, dialog modules, and event blocks. Both models can be used in parallel. You can use classes inside classic processing blocks or you can call classic procedures from methods. In ABAP Objects, SAP has implemented a cleanup of the ABAP language. Within the scope of this language cleanup, stricter syntax checks are performed in classes that restrict the usage of obsolete language elements.
Object orientation in ABAP is an extension of the ABAP language that makes available the advantages of object-oriented programming, such as encapsulation, interfaces, and inheritance. This helps to simplify applications and make them more controllable.
ABAP Objects is fully compatible with the existing language, so you can use existing statements and modularization units in programs that use ABAP Objects, and can also use ABAP Objects in existing ABAP programs.

Hi
What is ASAP methodology?
What is the use of ASAP?
What is the Diff b/w Solutiona manager and ASAP?
Thanks.Dear Swaroop,
AcceleratedSAP (ASAP) is SAP's standard implementation methodology. It contains the Roadmap, a step-by-step guide that incorporates experience from many years of implementing R/3. Along with that, AcceleratedSAP contains a multitude of tools, accelerators and useful information to assist all team members in implementing R/3. Quality checks are incorporated at the end of each phase to easily monitor deliverables and critical success factors. ASAP is delivered as a PC-based package, so that - if required - an implementation project can begin prior to having an R/3 System installed.
AcceleratedSAP (ASAP): A comprehensive solution for the introduction of the R/3 System in your enterprise. ASAP and most of its tools can be used independently of an R/3 installation.
The tools available for AcceleratedSAP are:
The <b>Project Estimator</b>, an internal SAP tool which enables SAP consultants to accurately gauge the required resources, the costs and the time frame of implementation. The Project Estimator takes into account the project scope and several project and risk factors.
The <b>Concept Check Tool</b>, a tool enabling you to carry out quality checks on the project preparation, technical infrastructure and R/3 configuration settings. This is done mainly during the first two implementation phases of the R/3 project. In this way you are alerted to potential data volume and configuration conflicts that could lead to performance issues if not addressed.
The <b>Implementation Assistant</b>: The ASAP navigation tool that accompanies you through the five phases of implementation down to the task level. It includes a description and a detailed "how-to" for each task in the Roadmap. Along with that, many tools, templates and documents are hyperlinked to the task. The Implementation Assistant contains the following elements:
<b>ASAP Implementation Roadmap</b> and <b>Project Plan</b>. The Roadmap contains the five phases, from which you can drill down into work packages, activities and tasks. The Project Plan contains three components, a budget plan, a resource plan and a work plan. These are explained in more detail in the next chapter.
The ASAP Roadmap is the successor of the R/3-based Procedure Model, which was used until Rel. 3.1 in R/3 implementation projects.
<b>Knowledge Corner</b>, containing tips and tricks for configuration from consultants, detailed documentation on SAPs implementation services, information on technical tools, as well as simplification guidebooks and R/3 Customizing wizards.
<b>Question and Answer Database (Q&Adb)</b>. Using the R/3 Reference Model structure, the Q&Adb is used to assist in gathering requirements for business processes, conversions, reports, interfaces, enhancements and authorizations. The database provides useful questionnaires to help you define the process needs and also serves as a repository for all this information. Since it is a database, it allows for flexible reporting. The business requirements generated from the Q&Adb are collectively known as the Business Blueprint.
<b>Business Process Master List</b>, to manage configuration, testing and the creation of end user documentation. The Business Process Master List is linked to pre-written Business Process Procedures (BPPs), detailled end-user documentation for R/3 transactions.
<b>Issues Database</b>: supporting project management, this database supports the entering, monitoring and managing of issues that come up during the project.

Some additional Infomation on ASAP methodology:
Phase 1 - Project Preparation
Change Charter - Goals and objectives of Organizational Change? Management
Project Plan - This is a first cut focusing on milestones and? Work Packages; details to come.
Scope - Sets the initial definition of the? project; input from sales cycle.
Project Team Organization - Sets the who? of the project: Standards & Procedures - Sets the why and how of the project.
Phase 2 - Business Blueprint - Requirements reviewed for each SAP Reference Structure item and defined using CI Templates (in the Q&Adb). Business Blueprint - This is the output of the Q&Adb and is the key document for Phase 3.
Phase 3 - Realization - Master Lists - Define business scenarios and R/3 transactions to be realized in the system. BPP - Business Process Procedures representing R/3 transactions; used for unit testing & documentation. Planning - Defines how the configuration will be done and how it will be tested. Development Programs - Provides details of the external programming requirements. EU Training Material - End User training material and process documentation.
Phase 4 - Final Preparation Stress & Volume Tests - Plans for confirming the production hardwares capabilities
Cutover Plan - The details of how to move to the production environment and go live
Conduct End User Training - Delivery of the necessary levels of R/3 End User training prior to going live
Phase 5 - Go Live & Support: Ensuring system performance through SAP monitoring and feedback.
Hope this will help.
