ABAP Class required ?

Hi All,
Is there any alternative standard class for the function module
"F4IF_INT_TABLE_VALUE_REQUEST". which performs the same operation as this fm does.
thanks and regards,

File to Proxy Scenario using ABAP Class and DB Multi Connect

Hello Friends,
I have a scenario below and a proposed solution. I would like some input as to whether i am headed the right way.
Scenario: Thousands of records come in from the legacy accounting system. The fields of these records need to be mapped to SAP fields using cross-reference tables stored in DB2. Finally, summarize the records by deleting a few fields and feed to R/3.
Solution i proposed:
(1) File Adapter is used to send the file
(2) Although JDBC adapter comes first to mind but since i need to access the DB2 tables multiple times for each record i propose to use an ABAP class for the mapping. Within the ABAP class the intent is to open an database connection to DB2, read the relevant cross tables using native SQL and finally generate the output XML.
(3) Reciever is Proxy which feeds this generated XML to SAP for creating posting via BAPI_ACC_DOCUMENT_POST
Question: Is the above solution correct or is there a better method to implement this scenario?
Please let me know.
Thanks,
Minhaj.

Looks fine. Few observations -
1. Whether it is ABAP class or Mapping in RFC lookup, you are making multiple trips to the database.
2. It looks like PI is being used only for reading the file and converting it to XML.
3. If using PI is not mandatory, then a complete ABAP class on ECC it self would be faster than swtching between PI Java, PI ABAP then round trips to DB2 finally data push to ECC.
If you could look at something like fetching all the required RFC look up data in one go and then map the fields according, might save u on processor and network resources.

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:

BOR Object and ABAP Class

Hi,
Can anybody say when to use BOR object and Abap class in the task with an example.
Thanks,
Mugundhan

There is no any specific condition or rule that for this purpose you need to use BOR and Class , it depends on your requirement. not only the requirement but also the new techniques to make classes not just as simple way to create objects but when you use classes in the Workflows they are not simple classes but they are BUSINESS CLASSES which makes a lot of difference.
Check the blogs of [Jocelyn Dart|https://www.sdn.sap.com/irj/scn/wiki?path=/pages/viewpage.action%3fpageid=55566]

BOR Object or ABAP Class

Hi Experts,
We are implementing the Leave Request WF using WS12300111. The user raises a leave request from the portal.
As per the functional point of contact, they have said that this WF can be set up in the configuration in SPRO to be triggered when a leave request is raised.
When we saw the standard SAP provided WF, the steps in it are based on ABAP class. I just want to know if the approach has to be only using ABAP classes or can BOR objects be used.
We require some customizations in the sense, we need to add some custom logic to retrieve some data from some custom tables and also display the same.
Kindly let me know if we need to use ABAP classes or we can use a BOR Object.
Cheers,
Belinda Clarke

Hi Karri,
Thanks a lot for your response.
I was actually evaluating the possibilities of the same as our WF consultant is currently on leave. I was just seeing a scenario where they have used BOR Object for Travel and Expenses module. When i saw the standard WF for Leave Request WS12300111, I was seeing mainly ABAP Objects and there was no BOR objects used.
I just wanted to confirm whether we could create a BOR Object or go on with the ABAP Classes. Does the ABAP Classes involve a lot of effort? We need to actually send email notifications and add some new steps etc...so was just thinking as to which would involve more effort.
We need to actually retrieve data from table PTREQ_ATTABS and send the email notification to the concerned user whenever the leave request is approved/rejected/cancelled as shown below :
Your leave request has been approved/rejected
Name : abcde
Emp No : 123456
Type of Leave : Annual Leave
Date : 7th July to 11th July
No. of Days : 3 days
So do u imply that all of this can be done with an ABAP Class
Could you kindly guide us.

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

Calling a custom tcode using abap class from workflow

Hi Experts,
I have a requirement of calling a custom tcode from my workflow.
For this i have created a class zcl_test ( has if_workflow ) .
I created a method ztest which will call the tcode.
CALL TRANSACTION 'ZTX'. ( My tcode just has 1 input field, for testing purpose )
Then i created a task in whichi hv used this abap class and method.
But the tcode does not run when i execute the workflow.
Please help.
Thank You,
Radhika Vadher.

Radhika Vadher
use the sample code to get the data from the task container into the ABAP class
DATA :
         w_ref        TYPE REF TO      if_swf_run_wim_internal,
         w_ref_cnt TYPE REF TO      if_wapi_workitem_context,
          w_wi_ref   TYPE REF TO      if_swf_ifs_parameter_container.
TRY.
    CALL METHOD cl_swf_run_wim_factory=>find_by_wiid
      EXPORTING
        im_wiid     = w_wiid
      RECEIVING
        re_instance = w_ref.
CATCH cx_swf_run_wim_enq_failed .
CATCH cx_swf_run_wim_read_failed .
CATCH cx_swf_run_wim .
ENDTRY.
CALL METHOD w_ref->get_workitem_context
RECEIVING
    re_ctx = w_ref_cnt.
CALL METHOD w_ref_cnt->get_wi_container
RECEIVING
    re_container = w_wi_ref.
and the w_wi_ref is having a method GET use that method to get the values of the task container into the ABAP class.

Calling ABAP class methods from JAVA application

Hi All,
I want to fetch ITS related information (SITSPMON Tcode) in my JAVA application. But i didnt find much BAPIs for the same. While debugging I came accross few class methods with help of which I can get the required information. So is there any way we can call and execute methods of ABAP classes through java application?
for e.g. I want to call GET_VERSION method of CL_ITSP_UTIL class.
Thanks,
Arati.

Hi,
Yes, as per my knowledge the only way to interact is using BAPI exposed as RFCs. So try to invoke those class methods in one CUSTOM BAPI and expose that BAPI as RFC and consume that RFC to get those details.

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...

Editing Colspan in ABAP class

Hi experts,
We have a report modified to aggregate like this (along with the axis info):
           x1           x2               x3
y1 Plant 1 | workcenter 1 | Result kf
y2 Plant 2 | workcenter 2 | Result kf
y3 Plant 3 | workcenter 3 | Result kf
y4 -
Overall Result-------| Result kf
Plant and workcenter are characteristics, result kf is a kf along our structure. The overall results row is the results row based on the Plant column. in this case it takes up 2 columns, x1 - x2, which is correct. we have a requirement were we hide column 2, so we only see the Plants and the immediate results:
           x1                               x2                                     x3
y1 Plant 1 | Result kf
y2 Plant 2 | Result kf
y3 Plant 3 | Result kf
y4 -Overall Result--| Result kf
our problem is the overall results row. it seems that it spans 2 columns (x1-x2) and it will not work if we hide I_X = 2 (column 2), and based on the source code from the report there is a colspan = "2". Does anybody know how to remove this colspan setting, or how to manitpulate the colspan? we are using abap classes to modify the reports.
any help would be greatly appreciated as this is quite urgent. points to be awarded accordingly.

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 Class as Service

Hi, What do I have to do to create a class and have it show up as an available service in VC?
Thanks, Ken Murray

I think the best way is to use an ABAP class as a service is to use it in a function module as Prachi has mentioned it.
Or you use it in an ABAP webservice so that every method is available via webservice, but it depends on your requirements, if you only need one method from the class then a function module is the best and quickest solution.
Best Regards,
Marcel

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.

ABAP classes for WebTemplate development

Hi experts,
I am manipulating a report via ABAP classes. I need to hide an entire column including the header. Currently I have done this under the DATA_CELL method and have only been able to hide the KF area. If I need to hide the Header in the column (built under a structure) as well must I move all my code under the CAPTION_CELL method instead?
Secondly, I also need to search for a row by the text "Overall Results." Is there a quick way to search the Y axis for this particular row using the text "Overall Results?
mark

hi Mark,
you can try in
method CAPTION_CELL
if i_iobjnm_row = 'your charateristic to be hidden'.
C_CELL_TD_EXTEND = 'style="display:none;"'.
endif.
and ...
method CHARACTERISTIC_CELL
if I_IOBJNM = 'your charateristic to be hidden'.
C_CELL_TD_EXTEND = 'style="display:none;"'.
endif.
and I_IS_SUM <> 'X' if result not hide
to search 'Overall Result' (if you didnt get yet), can try
method CHARACTERISTIC_CELL
I_TEXT
not sure what's your requirement, to hide a characteristic you can set it bex query designer, characteristic's property 'display' = no display.
hope this helps.
