Abap class to write strings

Hello all,
Does anybody knows if exists an abap-class to write strings in SAP console ? I'm looking something similar of System.out.println() in JAVA.
Regards,
Arthur

Hi
as per my knowledge its not possible to write ABAP classes in console like java..but we can run the programs through the console for that follow the below syntax..its very time consuming process..
check the below syntax it may be helpful for you...
C:\Program Files\SAP620\SAPGUI\rfcsdk\bin>startrfc
RFC command line interface
Syntax :
         startrfc [connect options] <function options>
where
function options =
          -F <function module
          -E <parameter>=<value>
          -T <table name>,<width>,[r=<file>][,w=<file>]
             where <file> is a path name to read from (r)
             or write to (w) the internal table.
             If <file> is -, stdin or stdout is used

XML to flat File:ABAP Class

Hi ,
Please can someone answer my question asap.
I have to write an ABAP Class which receives an XML Document which has multiple IDOCS.The IDOC has several Segments which can repeat and also the segments have Sub-Segments.
Please can someone provide me a sample code which can convert the fields of each segment to a line of the output flat file.
I need a flat file where fields under each segment should come in one line.I mean the control record should come in one line.The fields of 1st segment ex:E1EDK01 should come in 2nd line.....
Please revert.
Thanks in Advance,
Harish.

You will need to use ABAP ixml technology to parse the content from the xml file:
You can reference following ABAP mapping.

Abap-Class-Event in Wait Step

Hi guys,
in my workflow i have an activity with an abap method. This method works like a dialog. This means, i get a workitem in the business-workplace which shows a webdynpro where a pdf is displayed and where i can choose whether i click on button1 or button2.
When i click on one button, an abap-class event will be created. This event has a container. My target is, to bring the user desicion back to the workflow via event.
When i start a new workflow with this event then it works fine. But i dont want 2 workflows. I need a solution with one workflow. So i use a fork in my workflow. In branch 1 i have the activity which displays the pdf and create the event. In the other branch i have a waiting step, which waits for the event and bring the user-desision from the event-container to my workflow-container.
That was my plan, but it dont works this way. I checked the event-trace and theres no receaiver entered for my event. So my workflow stoped at the wait-step (wait step is ready).
I read, the the workflow system is automatikly doing the type-linkage and the instance-linkage, but i found only the instance-linkage filled. Can it be, that the wait step is only working with BOR-Events?
Any ideas?

Hi swangir,
i tryed this FW SAP_WAPI_WRITE_CONTAINER some days ago. I can use SAP_WAPI_READ_CONTAINER easylie but when i try to modify the container then i get an enqeue exception in the SAP_WAPI_WRITE_CONTAINER FM. I guess this came up, because i call the webdynpro from an activie-step in the workflow and not a dialog-step. So i guess the container is locked and i cant write. I also tried to unlock it with dequee_e_ .. FM i forgot the name. But it also didnt work.
Thats why i tryed to bring the user desision via event back to the workflow. And it works, as long i use 2 workflows, like i explained in my first post.
What do u mean with...
"Alternatively, you can bind back the class event container to workflow container by binding back from the dialogue step."

Abap class in portal application?

hi all,
I know how to call rfc function modules from portal applications. but as you all know ABAP is now a days written using classes and methods(Object Oriented), I would like to know how to access this classes and methods from a portal application.
please help me in this regard as my client has urgent need for this. is it mandatory to write an RFC enabled BAPI as a wrapper to the ABAP class.
Rgds

Hi Yogi,
if you want to access BAPIs, you can do that by using JCA or if you are using EP6 SP2 JCo.
There are JCA&JCo Code samples under the download section available.

Automatic generation of ABAP-classes from Function Groups?

Hey there,
is there a way of having (SE24)-ABAP-Classes generatetd outomaticaly by providing an existing function group?
I think, the following mapping shold be possible::
- the function group is the class
- its function modules are public (static) methods
- any form-routines are private methods
-> I don't want to to that boring work myself, some tool should be able to do that just fine, right? So, is there such a tool?
Thanks, regards
Joachim

Sorry, sounds like the only two people who answered are not aware of such a tool...
There is one additional point, which I hadn't thought about initially. With ABAP OO you also have a much stricter syntax and many more statement variants that are obsolete and thus cannot be used. This is another hindrance for writing such a tool (but of course not impossible, I just kind of doubt that any reasonable programmer would write such a thing).
Anyhow, I never understood why SAP is pushing OO so much (declaring all non-OO as obsolete), even going as far as implementing stricter syntax checks for OO. In my opinion a much better option would've been to implement some flag that switches on the more strict syntax checks, similarly to the Unicode check they've introduced. Coding in OO or non-OO, both have its use. Rules from SAP to code everything in OO even in cases where OO doesn't work seems straight silly as a general recommendation: E.g. if I have to code an RFC module, why would I want to bloat my code by introducing a class for implementing the functionality so that the RFC is just a wrapper around the class (unless the additional class gives me some real benefit)?
As much as I appreciate using OO classes supplied by SAP, I often have difficulties seeing objects in the requirements that I have to code (which might of course just be a reflection of my programming skills). A class with just some static methods is often an indication of poor OO design, i.e. there is no reasonable/tangible object and all you have is a utility class with a collection of various methods. To me it's important that the code is well structured, doesn't have any side effects, etc. This can be achieved with non-OO coding as well as OO, but switching from non-OO to OO doesn't guarantee at all that the code is any better.
In the end, if you just have a single function group, I'd recommend to do the translation manually and try to apply good OO design principles (instead of a straightforward 1-to-1 translation). E.g. for a class with just static methods (which I'd expect an automated translation would result in) one might want to take a peek at [singletons are evil|http://www.c2.com/cgi/wiki?SingletonsAreEvil] versus [singletons are good|http://www.c2.com/cgi/wiki?SingletonsAreGood]. I know it's silly advice if you're a seasoned OO programmer; but if not, I think your time is much better spent by thinking about the design and then applying it instead of using some automated tools where you'd later have to anyhow do some refactoring...

How to model ABAP classes in a correct manner?

Hi,
I'm creating a conceptual design for an ABAP Objects program. The program should collect some data from standard tables like VBAK, VBAP, etc. (SD environment) in one flat structure/table, calculate some characteristic numbers for each dataset and finally write the datasets to my own flat DDIC table.
This program should run every day as a planned job. There are some hundred up to 5000 datasets to be collected by my program every day...
Now the question: Is it an usual manner to model a ABAP class representing one dataset. Every collected dataset would be represented by its own object at running time...
I hope there are no performance issues!!
Regards,
Benjamin

Creating "good" OO classes (I mean reusable, easily extendable, simple to use) is not so simple when you have to deal with a complex model. The only solution is first to read many documentations (http://www.sdn.sap.com/irj/scn/advancedsearch?query=ooProgrammingwithABAPObjects) and then experiment by oneself.
This last is important, because even documentation does not provide exact inputs to all scenarios, and to the limits of the used OOP languages.
Note: I already saw people create "bad" OO classes: simple to use and understand in the initial program, but can't be reused or extended at all. In fact, OO programs can be written as badly as a bad procedural program (I mean without OO), and a procedural program can be written as good as a good OO program (yes it's possible!)
I remember I had rewritten complex classes (there was like inheritance from multiple classes) because my initial choice was not the right one, subclasses became standalone classes with delegation to the old parent class, and things like that. If I had initially released my classes in the first version (to be used by other developers), I probably should have duplicated them (more or less) to implement the new functions.
An existing example of classes that you can't reuse for a slightly different goal, are the tree classes (cl_gui_alv_tree, cl_treemodel*, etc.), if you want to handle trees in memory in background (it dumps if you try to use these classes), that you need to duplicate and adapt. It could be used to handle sets (GS01 transaction), menus, workbench objects where-used lists, file system, etc. Even XML tree classes can't really be used to handle non-XML trees. Currently, you have to create your own code to work with trees in memory in background (by creating our own generic tree class, for building and traversing). I feel SAP might have created such a class and used it in all its tree classes (and we could have benefit from it!)

ABAP Class to start Infopackage load

I want to write a little interface that allows a non-tech user to provide a desktop file (.csv) allow a selection of filetype (sales, repair, historical, demand) and a button to start the load process.
The file is then transfered to the BW system and afterwards uploaded using an appropriate Infopackage depending on the filetype.
Are there ABAP classes available that have methods to e.g. start the load of an InfoPackage?
Regards,
Eric

Hi Eric,
if you want to start or even create or change Infopackages by ABAP, you
could also use BAPIs. These are provided in BAPI Ecplorer (TC BAPI)
-SAP Business Information Warehouse
--Warehouse Management
---InfoPackage
Here you should find required methods

Capturing ABAP Class in Transport Request

Hi ,
Can anyone please tell me how to capture ana ABAP Class in transport request . IT first gave me an error saying :
'ZCL_PHX_MANUAL_SAVE===========CO missing then after capturing that , now it is giving me an error message saying
'ZCL_PHX_MANUAL_SAVE===========CI missing.
Can someone suggest me the correct method by which i can captur my class in request and transport it to Production.
Thanks and Regards,
Vijay Sanklecha.

Hello Vijay,
If your class name is ZCL_PHX_MANUAL_SAVE. Then SAP genereates its own includes for private,public and protected sections . Those are the includes that you have mentioned here.
Right mehtod for including the class in a request is
Go to Se80
Give your class name anf right click
Choose other functions-> write transport entry

RFC FM to ABAP Class

Hi,
Can we write RFC Function module into ABAP Class.
For better performance We'd like to instead of calling RFC FM use Classes. Is it suggestable this process, classes will be useful as RFC FM.
Thanks and Regards,
Prabhakar Dharmala

With introduction with SOA, you'll create "pesistence Service" with persistence object, that enables
the calls via RFC... but is a different logic...

Abap Class - Friend

Hello Forum,
What is the 'Friend' defined in a Class?
What is its role and how is it used together with Methods?
Any easy to understand materials on Abap class would be greatly appreciated.
Thanks!
Best regards,
S.Patel

Hi
Classes
LIKE-Zusatz
Classes are templates for objects. Conversely, you can say that the type of an object is the same as its class. A class is an abstract description of an object. You could say that 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
Classes in ABAP Objects can be declared either globally or locally. You define global classes and interfaces in the Class Builder (Transaction SE24) in the ABAP Workbench. They are stored centrally in class pools in the class library in the R/3 Repository. All of the ABAP programs in an R/3 System can access the global classes. 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, it then looks for a global class. Apart from the visibility question, there is no difference between using a global class and using a local class.
There is, however, 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, it is usually sufficient to define the outwardly visible components so that it fits into that program. Global classes, on the other hand, must be able to be used anywhere. This means that certain restrictions apply when you define the interface of a global class, since the system must be able to guarantee that any program using an object of a global class can recognize the data type of each interface parameter.
The following sections describe how to define local classes and interfaces in an ABAP program. For information about how to define local classes and interfaces, refer to the Class Builder section of the ABAP Workbench Tools documentation.
Defining Local Classes
Local classes consist of ABAP source code, enclosed in the ABAP statements CLASS ... ENDCLASS. A complete class definition consists of a declaration part and, if required, an implementation part. The declaration part of a class <class> is a statement block:
CLASS <class> DEFINITION.
ENDCLASS.
It contains the declaration for all components (attributes, methods, events) of the class. When you define local classes, the declaration part belongs to the global program data. You should therefore place it at the beginning of the program.
If you declare methods in the declaration part of a class, you must also write an implementation part for it. This consists of a further statement block:
CLASS <class> IMPLEMENTATION.
ENDCLASS.
The implementation part of a class contains the implementation of all methods of the class. The implementation part of a local class is a processing block. Subsequent coding that is not itself part of a processing block is therefore not accessible.
Structure of a Class
The following statements define the structure of a class:
A class contains components
Each component is assigned to a visibility section
Classes implement methods
The following sections describe the structure of classes in more detail.
Class Components
The components of a class make up its contents. All components are declared in the declaration part of the class. The components define the attributes of the objects in a class. When you define the class, each component is assigned to one of the three visibility sections, which define the external interface of the class. All of the components of a class are visible within the class. All components are in the same namespace. This means that all components of the class must have names that are unique within the class.
There are two kinds of components in a class - those that exist separately for each object in the class, and those that exist only once for the whole class, regardless of the number of instances. Instance-specific components are known as instance components. Components that are not instance-specific are called static components.
In ABAP Objects, classes can define the following components. Since all components that you can declare in classes can also be declared in interfaces, the following descriptions apply equally to interfaces.
Attributes
Attributes are internal data fields within a class that can have any ABAP data type. The state of an object is determined by the contents of its attributes. One kind of attribute is the reference variable. Reference variables allow you to create and address objects. Reference variables can be defined in classes, allowing you to access objects from within a class.
Instance Attributes
The contents of instance attributes define the instance-specific state of an object. You declare them using the DATA statement.
Static Attributes
The contents of static attributes define the state of the class that is valid for all instances of the class. Static attributes exist once for each class. You declare them using the CLASS-DATA statement. They are accessible for the entire runtime of the class.
All of the objects in a class can access its static attributes. If you change a static attribute in an object, the change is visible in all other objects in the class.
Methods
Methods are internal procedures in a class that define the behavior of an object. They can access all of the attributes of a class. This allows them to change the data content of an object. They also have a parameter interface, with which users can supply them with values when calling them, and receive values back from them The private attributes of a class can only be changed by methods in the same class.
The definition and parameter interface of a method is similar to that of function modules. You define a method <met> in the definition part of a class and implement it in the implementation part using the following processing block:
METHOD <meth>.
ENDMETHOD.
You can declare local data types and objects in methods in the same way as in other ABAP procedures (subroutines and function modules). You call methods using the CALL METHOD statement.
Instance Methods
You declare instance methods using the METHODS statement. They can access all of the attributes of a class, and can trigger all of the events of the class.
Static Methods
You declare static methods using the CLASS-METHODS statement. They can only access static attributes and trigger static events.
Special Methods
As well as normal methods, which you call using CALL METHOD, there are two special methods called CONSTRUCTOR and CLASS_CONSTRUCTOR, which are automatically called when you create an object (CONSTRUCTOR) or when you first access the components of a class (CLASS_CONSTRUCTOR).
Events
Objects or classes can use events to trigger event handler methods in other objects or classes. In a normal method call, one method can be called by any number of users. When an event is triggered, any number of event handler methods can be called. The link between the trigger and the handler is not established until runtime. In a normal method call, the calling program determines the methods that it wants to call. These methods must exist. With events, the handler determines the events to which it wants to react. There does not have to be a handler method registered for every event.
The events of a class can be triggered in the methods of the same class using the RAISE EVENT statement. You can declare a method of the same or a different class as an event handler method for the event <evt> of class <class> using the addition FOR EVENT <evt> OF <class>.
Events have a similar parameter interface to methods, but only have output parameters. These parameters are passed by the trigger (RAISE EVENT statement) to the event handler method, which receives them as input parameters.
The link between trigger and handler is established dynamically in a program using the SET HANDLER statement. The trigger and handlers can be objects or classes, depending on whether you have instance or static events and event handler methods. When an event is triggered, the corresponding event handler methods are executed in all registered handling classes.
Instance Events
You declare instance events using the EVENTS statement. An instance event can only be triggered in an instance method.
Static Events
You declare static events using the CLASS-EVENTS statement. All methods (instance and static methods) can trigger static events. Static events are the only type of event that can be triggered in a static method.
See also Triggering and Handling Events.
Types
You can define your own ABAP data types within a class using the TYPES statement. Types are not instance-specific, and exist once only for all of the objects in a class.
Constants
Constants are special static attributes. You set their values when you declare them, and they can then no longer be changed. You declare them using the CONSTANTS statement. Constants are not instance-specific, and exist once only for all of the objects in a class.
Visibility Sections
You can divide the declaration part of a class into up to three visibility areas:
CLASS <class> DEFINITION.
PUBLIC SECTION.
PROTECTED SECTION.
PRIVATE SECTION.
ENDCLASS.
These areas define the external visibility of the class components, that is, the interface between the class and its users. Each component of a class must be assigned to one of the visibility sections.
Public Section
All of the components declared in the public section are accessible to all users of the class, and to the methods of the class and any classes that inherit from it. The public components of the class form the interface between the class and its users.
Protected Section
All of the components declared in the protected section are accessible to all methods of the class and of classes that inherit from it. Protected components form a special interface between a class and its subclasses. Since inheritance is not active in Release 4.5B, the protected section currently has the same effect as the private section.
Private Section
Components that you declare in the private section are only visible in the methods of the same class. The private components are not part of the external interface of the class.
Encapsulation
The three visibility areas are the basis for one of the important features of object orientation - encapsulation. When you define a class, you should take great care in designing the public components, and try to declare as few public components as possible. The public components of global classes may not be changed once you have released the class.
For example, public attributes are visible externally, and form a part of the interface between an object and its users. If you want to encapsulate the state of an object fully, you cannot declare any public attributes. As well as defining the visibility of an attribute, you can also protect it from changes using the READ-ONLY addition.

Replace Abap-class by Java for Error

hi,
i tried what was said in Michal tutorial :
/people/michal.krawczyk2/blog/2007/04/26/xipi-throwing-generic-exceptions-from-any-type-of-mapping
but i faced some problems, first of all i dont have Abap-class in the settings of my Interface mapping i just only have java , XSL and also MM it s weird but anyway could i replace the Abap-class that read the dynamic configuration with a java-class mapiing that could write in the error tag of the soap header.
i followed the steps described in the tutorial i mean the code in the UDF but i cant use the Abap-class mapping in my interafce mapping is there any other way to write in the Error tag of soap header in the SXMB_moni
thanx

Hey
You need to add a parameter to exchange profile before you can see ABAP-class in Interface mapping,please follow the below steps:
Go to http://<host:port>/exchangeProfile in internet explorer
Expand IntegrationBuilder ->IntegrationBuilder.Repository->click on com.sap.aii.repository.mapping.additionaltypes link ,then on right hand side just type
R3_ABAP|Abap-class in i/o field. and save.
You may need to restart Java engine for this take effect.
Thanks

Job Schedule Custom ABAP Class Every 2 weeks

Hi Folks,
I would like to ask if possible to run custom ABAP class using JOB Schedule (SM36). I have created a custom class that needs to be run every two weeks.
Thanks,

Hi,
what do you mean by "run custom class"? If you mean calling methods of that class then no. But it is easy to write a simple report which will call required methods.
Cheers
