Regarding Other Pattern In ABAP Editior

Hi,
I have one doubt in ABAP. In ABAP editior we can call fuction module through pattern push button.Same way there i find other Pattern button also. So i want know what is purpose of other pattern and where we have create ? what is the Transaction?Kindly Help to me.
Thanks & Regards,
Ramya

other pattern is used for template purpose. u can create ur own templates there.
goto utilities->ptrn->edit pattern and create a new pattern
template means something like this
$$*________________________________________
FORMS name start with FS_
$$*________________________________________

How to implement Strategy pattern in ABAP Objects?

Hello,
I have a problem where I need to implement different algorithms, depending on the type of input. Example: I have to calculate a Present Value, sometimes with payments in advance, sometimes payment in arrear.
From documentation and to enhance my ABAP Objects skills, I would like to implement the strategy pattern. It sounds the right solution for the problem.
Hence I need some help in implementing this pattern in OO. I have some basic OO skills, but still learning.
Has somebody already implemented this pattern in ABAP OO and can give me some input. Or is there any documentation how to implement it?
Thanks and regards,
Tapio

Implementing DAO Pattern in ABAP

This discussion implement DAO pattern asked the question of how to develop a DAO pattern in ABAP but i'd like to go a little deeper.
The only answer given suggested the following design pattern:
I don't have an coded example here, but isn't it sufficient for this pattern to build an interface with some get- and set-methods? This interface can be implemented by several classes with different data retrieval logic. Then a static factory-method could do the job to decide during runtime which actual class is instantiated, returning the interface.
Can anyone give an abstract description of this implementation relative to an SAP module (How would one approach this implementation in MM, PM, FICO, HR)
Can anyone see any issues in this design?
Can anyone provide an alternate design?
Are we missing any steps?
Together we can build a solid abap DAO everyone can use.

I started to read about DAO pattern some days ago and found this great blog post:
ABAP Unit Tests without database dependency - DAO concept
I am starting to implement unit test in my developments and DAO pattern seems to be a clever choice.

Felipe

Design Pattern and ABAP Objects

Hello Friends,
I would like to know, if ABAP Objects can be used to do pattern oriented programming ?
For example GANG of four has provided almost more then 30 design pattern ( MVC, singelton, Obserable, FACADE,,,etc) can we implement patterns using ABAP ??
Many thanks
Haider Syed

Hi,
Take a look at the following site:
http://patternshare.org/
It has all the basic patterns from the GOF and a lot more. I can recommend the ones from Martin Fowler but be sure you start with the ones from the GOF.
All patterns are described by using UML so it's very easy to translate them into ABAP OO code.
Regarding your other question. For the observer pattern I used an interface which the SAP had already created if_cm_observer and created my own abstract observable class. The observable class is nearly a 100% copy of the java.util. one

Is abap thread safe? Some question in Singleton pattern in ABAP

Hi Grus,
I have a very basic question but really make me headache...
Recently I am learning the design pattern in ABAP and as you know in JAVA there is a key word "Synchronized" to keep thread safe. But in ABAP, I didn't find any key words like that. So does that mean ABAP is always a single thread language? And I found that there is a way looks like "CALL FUNCTION Remotefunction STARTING NEW TASK Taskname DESTINATION dest" to make multi-thread works. As you can see it use the destination, so does that mean actually the function module is always executed in a remote system, and in every system, it is always single thread?
Could you help me on the question? Thanks a lot, grus
And here comes up to my mind another question...It's a little bit mad but I think it may works....What if I set every attribute and method as static in the singleton class...Since as you can see it is already a singleton so every attribute in it should be only one piece. So then I don't even need to implement a get_instance( ) method to return the instance. Just call "class_name=>some_method( )" directly then singleton is achieved...What do you think?
BR,
Steve

Steve,
I've the same question, few days ago I tried to use the singleton in ABAP. In Java programming is possible to use the same reference in two sessions or programs, sharing attributes, methods and all data, but I could not do in ABAP.
In my test I created a program with one global class using the singleton pattern, so I expected that when I run my program and see the reference returned after the get_instance method it should be equal to the same program run in another session, but the ABAP will create a new reference and instantiate again.
So I deduced that the only way to share it between sessions in ABAP is using the ABAP Shared Memory Objects.
I can be wrong, but I think that ABAP use a thread by user session (Each window) and we can't change it.
Best regards.

Design Patterns in ABAP.

Hi,
I want to know about the Design Patterns in ABAP.
Regards,
Sourav

hi sourdi
Below are the list of Design pattern in abap .
Singleton: ensuring single class instantiation
Adapter: making class interfaces compatible
Factory: encapsulating object creation
MVC: decoupling business logic from the view
Facade: providing a simplified interface
Composite: treating individual objects and compositions uniformly
Decorator: forming a dynamic chain of components to be used as one by the client

Is it possible to call a class method using pattern in ABAP editor.

Hi,
Is it possible to call a class method using pattern in ABAP editor.
Thank U for Ur time.
Cheers,
Sam

Yes,
Click patterns.
Then choose Abap objects patterns.
Click on the Tick
It will give a new screen
Here Give the name of the class first.
Then the object (instance of the calss)
And finally the method ..
it will give you the pattern
Hope this helps.

Setting up custom patterns in Other Patterns

Hi Experts,
Where can I set up my own custom pattern so that its inserted into my report when I give the corresponding name in the other patterns button?Is there any thread for the same...which explains the steps.
Thanks and Regds
Abhi
Edited by: abhishek singh on Jul 28, 2009 12:09 PM

Hi Abhisek,
If you want to create your own patterns, you can follow this step:
menu utilities --> more utilities --> edit pattern --> create pattern.
Type in the code you want to use as a pattern.
Save it and back out.
Now once you create it there, you should be able to enter in the "Other Pattern" field.
Hope it will help you.
Thanks,

Regarding Server patterns

HI guys,
Could you guys tellme what are the Merits and demerits in installing SAP/DB in different pattern as follows
1) SAP/DB in one box
2) ABAP/DB in one box and JAVA/DB in another box
3) Installing all instances(CI/DI etc) seperately
Have any document related to this..explaining about this

Can you install a java add-in to a database other than the abap database?

When doing a java add-in installation into an ABAP stack, is it possible to put the java into it's own database, not just a different schema in the same database? If so, do you know where in the installation process it lets you do this? Thanks.

Hi Rick,
No its not possible.
For addin installation procedure, you have to follow the installation guide of the particular release.

Regarding BADI's in ABAP

Hi,
Can anybody tell me What is meant BY BADI's!
Also what are the main diffrences between User-Exits and BADI's!
Can anybody explain me wether any diffrent types of BADI's are available!
Can anybody provide me documentation with the examples
for BADI's.
If anybody is having good material on the same please post it.
(or)
Please send the material to

I.What is Badi?
1.New SAP enhancement technique
2.To accommodate user requirements not available / too specific to be included in the SAP standard Program
3.Based on ABAP Objects It has Interfaces & Methods
4.Guaranteed upward compatibility of all Business Add-In interfaces
-Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces
II.BAdi & Customer-Exit
1.Though different enhancement technique, BAdi has following distinct features
-Uses Object oriented approach
-Two parts - Definition and its Implementation - definition can either be SAP provided or user may also create it
-no longer assumes a two-system infrastructure (SAP and customers)
-allows multiple levels of software development (by SAP, partners, and customers, and as country versions, industry solutions, and the like)
3.BAdi where to find
1.Look for BAdi in IMG and in component hierarchy (using transaction SE18)
2.Create own implementation of the add-in (complete coding for Methods) and activate
3.Enhancement's active components are called at runtime.
BAdi Definition (SE18)1.To include Business Add-Ins in the program
- Define an interface for the enhancement in the SAP menu under Tools-> ABAP Workbench -> Utilities -> Business Add-Ins -> Definition (transaction SE18)
-Call the interface at the appropriate point in application program
-Customers can then select the add-in and implement it according to their needs
BAdi Implementation (SE19)
1.ABAP Workbench ->Utilities -> Business Add-Ins -> Implementation (transaction SE19)
2.Find the suitable Business Add-Ins present in system (Use IMG or Component hierarchy)
3.Use Add-Ins Documentation to understand functionality & to decide
4.Implement the Add-Ins
-a class is created with the same interface
-Finalize coding for the method
5.Implementations are discrete transport objects and lie within the namespace of the person or organization implementing them
check the SAP help link on BADI's

Regarding parallel queries in ABAP same as in oracle 10g

Hi,
   Is there any way we can write parallel queries in ABAP, in the same way we do in oracle 10g.Kindly see below;
alter table emp parallel (degree 4);
select degree from user_tables where table_name = 'EMP';
select count(*) from emp;
alter table emp noparallel;
SELECT /*+ PARALLEL(emp,4) / COUNT()
FROM emp;
The idea here is to distribute the load of select query in multiple CPUs for load balancing & performance improvement.
Kindly advise.
Thanks:
Gaurav

Hi,
>    Is there any way we can write parallel queries in ABAP, in the same way we do in oracle 10g.
sure. Since it is just a hint...
SELECT *
FROM t100 INTO TABLE it100
%_HINTS ORACLE 'PARALLEL(T100,4)'.
will give you such an execution plan for example:
SELECT STATEMENT ( Estimated Costs = 651 , Estimated #Rows = 924.308 )
       4 PX COORDINATOR
           3 PX SEND QC (RANDOM) :TQ10000
             ( Estim. Costs = 651 , Estim. #Rows = 924.308 )
             Estim. CPU-Costs = 33.377.789 Estim. IO-Costs = 646
               2 PX BLOCK ITERATOR
                 ( Estim. Costs = 651 , Estim. #Rows = 924.308 )
                 Estim. CPU-Costs = 33.377.789 Estim. IO-Costs = 646
                   1 TABLE ACCESS FULL T100
                     ( Estim. Costs = 651 , Estim. #Rows = 924.308 )
                     Estim. CPU-Costs = 33.377.789 Estim. IO-Costs = 646
PX = Parallel eXecution...
But be sure that you know what you do with the parallel execution option... it is not scalable.... .
Kind regards,
Hermann
