ABAP Class not displaying in operation mapping.

HI,
I have created abap class using se24 for throwing exception message in sxmb_moni, this abap class needs to be called in operation mapping, even though i have activated this abap class in PI environtment, i couldnt see the abap class option in the operation mapping.
Could any one please let me know any change profiles requirements are required,
Thanks,
--Sai

Hi Sai,
Yes, you do have to register ABAP Class Mapping in the Exchange Profile to see this option in the Operation Mapping. Follow these step-by-step configuration guidelines:

Message Mapping of type ABAP Class not being shown

Hi all,
I have been trying to follow the given blog:
/people/ravikumar.allampallam/blog/2005/02/10/different-types-of-mapping-in-xi
Even after doing the changes mentioned in the blog, i do not see the ABAP Class in the list of Message Mapping types.
Do i need to do anyother configuration. Pls guide.
Regards
Neetu

Hi Neetu,
You will have to enable your ABAP mapping first.
Do the following steps, pay carefull attention to the values you enter,
In
IntegrationBuilder ->IntegrationBuilder.Repository -> com.sap.aii.repository.mapping.additionaltypes
enter the value of
R3_ABAP|Abapclass;R3_XSLT|XSL (ABAP Engine)
If the above doesnt work, try Abap-class instead of Abapclass in the above line.
And then follow the remaining steps, make sure that the above value is correct. Your ABAP mapping should appear in your Integration Repository.'
I suggest you go through these links:

How to use ABAP Class to modify Web Query Result ??

Hi all !
We are using Web Templates to display our Query.
What I would like to do ( and seems a really important issue for our users! ) is to have a "PAGE BREAK" everytime the value of a charateristics change in the report
For Example :
-Page 1-
Division     Project
   A               1
                    2
                    3
-Page 2-
Division     Project
   B               1
                    2
                    3
and so on....
I read threads about using ABAP CLASS but no example what so ever...
We are presently under BW 3.1 but are considering upgrading to 7.0 by the end of the year so if there is a solution to my problem on either version i'd like to know.
If anyone has any information about how I can do this it would be most appreciated
Thx
JB.

Hi Yong,
Ravi is right, first check the blogs by Jocelyn, and if you still have specific questions you can ask them. I have used ABAP classes in workflow and I know Mike Pokraka tries to use classes exclusively.

BOR reference in ABAP Class

Hello,
I am writing method in ABAP class which I will link to the Workflow Step. I want to access values of one of the Workflow Element which is Multiline and refering to BOR Object Type. My queries are as below:
1. How should I define Importing Parameter of Method which will import values from the Workflow Element which is Multiline and refering to BOR object type.
2. If I change value of that Workflow Element (Multipline refering to BOR object type) in ABAP class method, will it be automatically reflected in Workflow Container due to binding?
Edited by: Ashwin Sonkusare on Apr 1, 2011 3:35 PM

Hi,
1. How should I define Importing Parameter of Method which will import values from the Workflow Element which is Multiline and refering to BOR object type.
Please create a table type same as workflow multiline element type. ( You can also use standard table if present ).
Then use this table type as the type of the import parameter of the class.
Then u can pass the multiline element of workflow to abab calss
2. If I change value of that Workflow Element (Multipline refering to BOR object type) in ABAP class method, will it be automatically reflected in Workflow Container due to binding?
If u change the Workflow Element (Multipline refering to BOR object type) in ABAP class method, then u need to update the values of the workflow multiline element through reverse binging ( binding abap class to WF ).
Thanks and regards,

Create an event using abap class (transaction swetypv)

Hi,
Im trying to create an event by using an abap class.
The purpose is to update po reqs using BAPI_REQUISITION_CHANGE upon saving a sales order. The exit is called on saving a sales order MV45AFZZ.
In MV45AFZZ the method cl_swf_evt_event is called and the object type, event, objkey and obj cat is exported.
Object Type = ZBUS203200
Event = Z_TRAD_ORDER_CHANGE_OO
I created my class ZCL_UPDATE_PUR_REQ (by copying CL_SWF_RUN_WIM_HANDLER
And using interface name BI_EVENT_HANDLER_STATIC )
In /nswetypv I assigned Class ZCL_UPDATE_PUR_REQ
to Object Type ZBUS203200
And Event Z_TRAD_ORDER_CHANGE_OO.
All that works fine except for passing in the objectkey.
In Class ZCL_UPDATE_PUR_REQ
Method BI_EVENT_HANDLER_STATIC~ON_EVENT
When I go to create a parameter for object key, I get the message
Parameters/exceptions of inherited methods or events cannot be changed.
Has anyone any suggestions for how I can get the object key into the method call BI_EVENT_HANDLER_STATIC~ON_EVENT?
Thanks
Ann

Hi Johann,
You don't need a class to do the job if you are on a 6.10 or higher system. Use command CALL TRANSFORMATION to create an XML from an internal table.

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 auto refresh planning application -- using ABAP Class?

Hi
I have written few planning functions and attached them in one single planning sequence. One of the planning function in this sequence is de-activate data slice checkmark in planning modeler. If I execute this planning function indiviually then it works great however when I use this function in sequence then second function in row doesnot identify changes made by first function(data slice inactivate) and thus throws errors.
At the same time, if I refresh my planning session and re-execute the planning sequence then it does works as REFRESH activates the changes done by first function (de-activate data slice).
I am wondering if there is any ABAP class that can trigger this auto refresh in background else some other method to do this auto refresh ?
Please let me know if you have any thoughts on this one.
Thanks and happy holidays
Al
Edited by: Al Gon on Dec 21, 2007 3:56 AM

Hi Al,
The planning fn to deactivate was ineffective in a sequence was because the sequence which executes the functions does it on the data in the buffer and not actually on saved data, while your deactivation would work on the data after its saved.
You could perhaps run that function separately from the others in the sequence and save the data first and then perform your "deactivation" function.
Merry Christmas

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

ABAP Classes and BADIs for HR

Hi all,
Can anyone give me a list of classes SAP has released for HR use by customers and all utility ABAP classes. Also any utility abap classes that would be useful for future. I am only interested in those relevant for ECC 5 and up.
Could you supply the BADIs or Enhancement Spots for HR too.
Thanks
Wayne

The BADI's I have found most useful are the BADI exits that duplicate the existing PA30 PAI / PBO User exits. If you trace back to where the exits are called you will find the BADI call within a few lines of code - but the difference is that the BADI is called outside one layer of IF logic, so it gets called in some circumstances where the user exits do not - I think this was to do with certain change or copy data situations.
Can't remember the name of the BADI, and do not have a system available to check at present, but it was not hard to find when I looked in the system.
Others I have used are as exits in the HR to FI posting interface, and also some in the travel to vendor interface. There is also an exit for customising the PERNR search help - cannot remember if this was a class or a FM.
For moving data inside the user exits in a unicode compliant way there are classes for moving data from the flat PRELP character structure to individual infotype structures - CL_HR_PNNNN_TYPE_CAST=>PRELP_TO_PNNNN and CL_HR_PNNNN_TYPE_CAST=>PNNNN_TO_PRELP.
For general unicode compliant constants such as a Tab character there is class CL_ABAP_CHAR_UTILITIES with attributes like CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB.
Also if you go to SE38, select the Blue "Online Help" button, and then go to the ABAP Overview, you will find under the ABAP by Theme branch an entry "ABAP System Classes and Interfaces" which documents 20+ general ABAP classes
Hope this helps

Abap Class or program

Dear Experts,
I am using BI 7 and BEx query.
I need to process data before it is presented in a BEx Excel report.
I would like to find out which Abap class or program from SAP I can use for this purpose.
I remember for web reports, there is an Abap class that can be used but not sure what the counterpart is for BEx.
regards
M Russo

Hi,,
You can change data by using BADI "RSR_OLAP_BADI ", which is actually used for virtual characteristics and Keyfigure.
But you can use that for your purpose as well.

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.
