Able to store abap class instance in trex

HEllo all,
I am new to enterprise search,is it possible to store an abap class instance in trex,basically i store a key value and
an abap class instance against this key value.
regards
kaushik

Good one, Singleton is definitely a good way of doing things.
But I'm looking for way to track instance of object, isn't it really no way of doing so?
Then why tools like jps (java version of ps (like command in unix) ) is possible?
Isn't there a generic way to do this, since Java was build from the ground up with object -oriented in mind, why these pool of objects are not maintainable by user(a developer in this case)?

How to store a class-based exception as container element?

Hello,
In a BO type method, there are situations where unexpected class-based exceptions can occur, I handle them with TRY ... CATCH ... ENDTRY.
If such an error occurs, my BO type method also returns a BO type method exception using a return code (as usually).
1) Now, my question is how can I store the exception instance in the task container ? (so that to get more information about what happened... it is an unexpected error as I said)
Note that my question may apply to any class instance.
2) To achieve this, I have an idea but not sure if it's realistic (maybe the question is not realistic too ). I'll create a new BO type ZOOINSTANC with string attribute containing the serialized instance, with a method to display it.
Example how it could work, in my BO type method (it returns EXCEPTION parameter of type ZOOINSTANC):
TRY.
CATCH cx_root INTO lo_exc.
    DATA l_exc TYPE string.
    CALL TRANSFORMATION id
        SOURCE oo = lo_exc
        RESULT XML l_exc.
    DATA l_bor_zooinstanc TYPE swc_object.
    swc_create_object l_bor_zooinstanc 'ZOOINSTANC' ''. "no key
    swc_set_property l_bor_zooinstanc l_exc.
    swc_set_element container 'EXCEPTION' l_exc.
    exit_return 1001 '' '' '' ''.
ENDTRY.
One important issue is that I don't know any API to display the instance :-p
Do you have any ideas, advices, ... ?
Thx
sandra

Hi Mike, thank you for your answer, and sorry for the delay.
> I'd rather go with the idea of returning the error details in a structured format that you can view in the container
Yes, but that's the issue as I don't know which exceptions can be triggered, as I'd like to handle all exceptions.
> I'd also ask why it's necessary to use BOR for this?
When a BOR method fails, I want technical support to have all the details of the error, not only a generic error message. It's why I want to store the exception in the workitem container, and be able to display it later.
> It's obviously your own development, so why not use classes. Subclasses of CX_BO_ERROR are recognised by workflow and you can even bring a proper message back to the WF log. There's also some info on this in the second edition of the WF book.
I did a test using demo workflow WS56400159 ("absence"), where I forced CX_BO_ERROR right after SWX_FORMABS_CREATE call in CL_SWF_FORMABSENC / CREATE method, but it seems that only the short text of the exception is kept.
So, I'm a little disappointed to see that we have a great exception "tool" with class-based exceptions, but only the last text is kept in the system! That would have been great to be able to store the whole information (the attributes, and the whole bunch of cascading exceptions (PREVIOUS attribute), instead of only a simple text).

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.

Shooping cart creation in SRM 7.0 using web dynpro ABAP classes.

Hi,
We have recently upgraded to SRM 7.0 from SRM 4.0. We are using customized portal application for the creation of the shopping cart.I am planning to create custom FM which will use the standard Web dynpro ABAP classes to create the shopping cart.
Could you please guide with the classes that are need to be implemented and the sequence of the classes used in the shopping cart creation.
I think these are the classes that are used in the standard web dynpro ABAP component.
CL_FPM_EVENT ->                  Creates an instance of this class based on an event ID.
CL_BADI_FLT_DATA_TRANS_AND_DB -> Data Handling: Transport and Database.
CL_EXITHANDLER ->               Class for Ext. Services Within Framework of Exit Technique.
CL_EX_BBP_DOC_CHANGE_BADI ->     BAdI Class CL_EX_BBP_DOC_CHANGE_BADI.
CL_BBP_OBJECTS_ACCESS ->         Access Functions for Object Types.
/SAPSRM/CL_PDO_BO_SC ->          Shopping Cart BO.
Your expert comments will be appreciated...

Is there a way to access ABAP OO instances from a batch job report

Hello,
I am looking for a way to access ABAP OO instances from a batch job report. My circumstances are the following:
I have got some ABAP OO coding that identifies other objects (class instances) that have to be processed (they have a DoIt method that does some calculation). As this processing is time consuming and performace relevant I have to parallelize this in batch jobs. This batch jobs however can only be "simple" ABAP reports according to SM36. The problem is now that I dont really know how to tell the batch job report what objects to process. Somehow I have to access theses instances from that batch job report.
Does anybody have an idea?
Greetings
Matthias

Hi David,
thanks a lot for your help. After a lot of searching on the net this seems to be the only way to cope with it. However I am not sure about the locking mechanisms and if its suitable for mass data processing. In the help page you suggested the following is stated which I do not fully understand::
"The current lock logic does not enable you to set specific locks for the following requirements:
·        Many parallel read and write accesses
·        Frequent write accesses
·        Division into changeable and non-changeable areas
Although the lock logic makes the first two points technically possible, they are not practical because most accesses would be rejected."
Does this mean
a) if I dont want to set "specific locks" for frequent write accessess I am fine
or
b) I am discouraged from use shared memory technics for frequent write accessess?
In the latter case I will have a problem...
What do you think?

Event triggering by abap class & ISR

hi gurus
1 ) can i able to see the event triggering by abap class in SWEL ? ,
2) in custom ISR scenario , new form scenario has been created by our functional consultant , and asking me to trigger a workflow for approval , when employee fills that particular ISR FORM , workflow should start and to go his HR administrator , when HR administrator double click on workitem he should get the ISR form in display mode & also with some descpition text is to be added in the screen (like user decision description ) with approval button ..... my question is how to trigger a event from in form scenario ? , how to bring the FORM screen to display mode to the HR administrator ?
regards
surya

Hi Surya
The BO for ISR forms is BUS7051 - Notification. Turn on the trace via SWELS and create a PCR/ISR form and you should see the events being triggered in SWEL.
Good Luck

Hi,
it took me some time to understand what the code should do.
First of all please let me say, that wiring trough the error cluster is immanent for debugging. One problem I see is that the refnum from the document element is zero, so that all other calls for childs are failing. You will only notice this by debugging or execution highlighting (see James hint). You will also see a hint for a problem in this region of the code when you look at your indicator loadXml. This once was always False.
I have changed two things:
LoadXml.vi -> Read from Text File instead of binary
Main.vi -> Using the read text for input of the LoadXml invoke method and not the pretty printed one.
Now LoadXml performs the action and your 2D array is filling in some stuff. My advice would be to carefully debug your code and look, where references get lost and where errors occur.
Good Luck

Create Attachment in workflow through ABAP Class in ECC 5.0

Hi,
Wr are using SAP ECC 5.0 and i am trying to create attachment through ABAP class.
Here in ECC 5.0, macro INCLUDE cntn01_swc is not available.
I am getting an error in declaration of SOFM object, because again SWC0_OBJECT is not available.
I've tried creating the parameter as type SOFM and of type table of SOFM but it also not working.
Can anybody help me how i can create SOFM instance in ABAP class in ECC 5.0?
Regards,
Smit

Hi
I am not very much sure about ECC 5.0 environment. Firstly are you looking to create a SOFM object inside any class or program or Function module , If yes then you need to include a include INCLUDE CNTN01_SWC (No arrow brackets) if this include is not available then use INCLUDE<CNTN01> then declare a variable of type SWC0_OBJECT if you are using first include or declare of type SWC_OBJECT.
Once you include any of the includes then by making use of SWC macros you can create a object
SWC0_CREATE_OBJECT <VARAIBLE> <BOR NAME> <BORKEY> for first include.
SWC_CREATE_OBJECT <VARAIBLE> <BOR NAME> <BORKEY> for second include.

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 reference in persistent container

Hi all,
Has anyone ever tried to read an abap class reference from a rule container in the rule's function module?
This doesn't seem to work, unless I am doing something wrong...
Here is the scenario:
I have an abap class ZCL_CLASS instantiated in my workflow container. In one of my workflow steps I pass that class object reference to a rule (Function Module based). In the rule function module I use macro swc_get_element to try to get the class object reference. And there it is not getting anything.
I have already tried the following:
- Try to run macro swc_container_to_runtime on the rule container before retrieving the object reference -> doesn't work. The internal table ac_container doesn't even look different before and after having run this macro.
- Try to replace the declaration of include <CNTN01> by <CNTN02> + <CNTN03>. Doesn't change anything either.
When I look at ac_container in debugging it seems my object reference is there but looks a bit strange:
ELEMENT | TAB_INDEX | ELEMLENGTH | TYPE | VALUE
WFIBF_PORTAB | 000011 | 004 | u | SWFTSTRUCT
WFIBF_PORTAB | 000012 | 032 | C | STEP
WFIBF_PORTAB | 000014 | 032 | C | 1CCC1000C
WFIBF_PORTAB | 000015 | 104 | C | <object key>    <class>    CL
Any idea of how I should proceed to retrieve my object reference?
For the moment the workaround I found is to pass the object key to the rule and to reinstantiate the class in the rule function module. Not a very elegant solution...
Thanks in advance and kind regards,
Patrick

Hi Mike,
I understand what you're saying. But the problem is that the swc_get_element macro does not even get me the LPOR value, and therefore I can't call the FIND_BY_LPOR method.
That means I have two solutions:
- Passing the LPOR instead of the object reference to the rule container => Not a very nice solution, for many different reasons.
- Find an alternative to swc_get_element to get the LPOR value.
I had a look at class cl_swf_cnt_container, and it seems it can do the trick for me.
So what I will finally do is:
1. Convert the BOR container into an instance of cl_swf_cnt_container.
DATA: lo_cnt    TYPE REF TO if_swf_cnt_container,
             lt_container TYPE swconttab.
lt_container[] = ac_container[].
TRY.
      CALL METHOD cl_swf_cnt_container=>if_swf_cnt_conversion~create_from_bor_container
        EXPORTING
          values                = lt_container
        RECEIVING
          container           = lo_cnt.
    CATCH cx_swf_utl_obj_create_failed.
ENDTRY.
2. Get my container element.
DATA: lo_myobj TYPE REF TO zcl_class.
CALL METHOD lo_cnt->if_swf_ifs_parameter_container~get
EXPORTING
    name       = 'MyContainerElement'
IMPORTING
    value      = lo_myobj
I didn't take the time to debug that deep in the standard SAP code, but I assume the if_swf_ifs_parameter_container~get re-instantiates my class for me.
Please feel free to comment.
Kind regards,
Patrick

ABAP class in task

Hello,
I'm using a ABAP class in a task, but when I triggers the workflow in this step its gets blocked with the status "in process".
The abap class is public and the method that I'm calling is static, Also I have implemented the IF_WORKFLOW interface to use from the task.
Do you have any sugestion about this to don't get block?
Thanks

Hello Diego,
when using class-based tasks, most exceptions thrown during the prepare and execution steps are generally caught and not beeing forwarded into the workflow log, especially when there's a general problem with the method definition.
In this particular case, the execution of static methods probably runs into an exception, as an instance is (accidently) required, even though -- by definition -- the method is instance-independent. For sure, class methods cannot be called as functional methods in container operations. Possibly the method was instance-bound at the time, the task was created, and later on changed to a class method. Re-Creating the task could be helpful here. Otherwise pass an instance to the task container (event though not required) and let the runtime system have it to call the class' method.
With the very best wishes,
Florin

How to get a reference to the owner of a class instance?

Within a method of a class, how can I get a reference to the
object containing the class instance?
To be clear: I have class B that contains a method, say
"myfunc()". Class A (say, the application itself or a custom
component) instantiates a new instance of Class B : myclassB=new
ClassB()
Now, from within myfunc() can I get a reference to Class A?
The simplest way here is to pass a "this" reference when
calling myfunc(), i.e. "myclassB.myfunc(this)" but I would prefer
not to have to remember to always use 'this'.

Are these objects within each other. Does classA own classB?
If that is the case, then Greg is correct and it should be
available in parentDocument.
In projects in the past we have created a central
refObjectLocator object that is available to all objects.
Mostly we use events to communicate between objects. Dispatch
an event and let whoever listen for it.
Here is a copy of our reflocator if you are interested.
package com.goconfigure.model {
import mx.collections.ArrayCollection;
import com.adobe.cairngorm.model.ModelLocator;
import com.goconfigure.util.HashMap;
[Bindable]
public class RefObjectLocator implements ModelLocator {
// this instance stores a static reference to itself
private static var refObject : RefObjectLocator;
public var refObjectHM : HashMap = new HashMap();
// singleton: constructor only allows one model locator
public function AppLocator() : void {
if ( RefObjectLocator.refObject != null )
throw new Error( "Only one RefObjectLocator instance should
be instantiated" );
// singleton: always returns the one existing static
instance to itself
public static function getInstance() : RefObjectLocator {
if ( refObject == null )
refObject = new RefObjectLocator();
return refObject;
public function addRefObject( pRefObject : Object, pName :
String ) : void {
refObjectHM.put(pName,pRefObject);
public function getRefObject( pName : String ) : Object {
return refObjectHM.getValue(pName);

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...

Abap Class for Enterprise Service

Hi guys.
I've published as webservice in SAP ECC as enterprise service get it in Enterprise Service Workplace.
I have two questions:
1- How can I know the abap class associated to this enterprise service.
2- Could I extend the functionality of this enterprise service? For instance I'd like to response with one more field. Is that possible or I have to create a new one?
Thaks a lot.
Regards.
