Business object reference in ABAP Classes

Hi All,
Here is my requirement.
1) I have a Business Object (say e.g BUS2012) instance in my workflow container
2) I have a task in my workflow referring to a Z-Class and its method (M1)
3) I want to access the attributes of the above Business Object (BUS2012)in the method (M1)of the class.
Please let me know how ? Sample code will be more helpful.
Thanks,
Deb

Hi Deb,
Please check the following [thread|Re: Creating instance of Business Objects;
Hope this helps!

How to Handle Business Object event in ABAP class

Hello Everybody,
I wanted to know if it was possible to reference BOR objects in ABAP class and handle BOR events in ABAP Objects.
Thanks in advance.

Hi,
Catch the et_VALIDATE event, when InnerEvent = False and ItemChanged = True.
            If pVal.EventType = BoEventTypes.et_VALIDATE Then
                If pVal.InnerEvent = False And pVal.ItemChanged Then
                    'TODO Your code here...

Integartion of Business objects explorer with ABAP ALV

Hello all,
We have a requirement to integrate one of our applications with business objects explorer. The complete details is as listed below:
1. Our application basically collects feedback provided by users and then displays an ALV with all the feedback ratings received for a topic.
2. It summarizes to the user the average rating received, number of 1star ratings , 2 star ratings etc.,
3. Instead of showing this in the ALV format we have requirement where we want to upload this data into the Business Objects explorer so that the user has a more user-friendly and intutive display of the same data rather than in a ALV.
Any inputs on how we can trigger business objects explorer from ABAP code and pass the data in the internal table used for ALV display to it would be very helpful.
Warm Regards,
Naveen M

HI Naveen,
there has been a demo of this by Enterprise Geeks during TechED 2009 and the code is posted on their website.
the other option is to export the data to Excel and then use BusinessObjects Explorer in the cloud for example.

How to Execute the Business objects created in ABAP from webDynpro applicat

Wht is the steps , or where the help documents are available for accessing the Business objects created in ABAP or R/3 systems from webDynpro project.

Hello Vishal,
I couldn't find any useful documents for your purpose.
However i had a similar requirement and had implemented the same using GCP APIs. But before i send you the code help, i would like to know your exact requirement. What are you trying to achieve? Are you just wanting to execute the BO and get the result? Or is your requirement has got something more to do?

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,

Invocking Business Objects Explorer from ABAP

hello all,
Is there any class available in ABAP which can be used to invoke BOE from ABAP so that we can pass the data in our internal tables to it and display it visually using business objects explorer.
Is there any other such way in which the data in internal tables can be displayed in form of graphs to the user in ABAP
Warm Regards,

Calling Business objects Methods from ABAP program

Hi All,
Can anyone please tell me the procedure to call methods of business object(Ex: BKPF) from an ABAP program. My requirement is to check the existence of a object key by using the method EXISTENCE CHECK from BKPF. Please help

Here is an example from the SAP documentation.

CALLING BUSINESS OBJECT FROM AN ABAP REPORT

Hi friends,
           I have a business object to which a Custom Function Module is assigned in one of its method.This Function Module calls a Bapi to update a Service Order.I need to capture the status of Idocs regarding success or failure from the function Module in the ABAP Report.I would like to know if there is any way to call this business object from my report and get the status of IDOC.
Regards,
Dev Reddy

sorry I think i was not clear in explaining .I am calling a BAPI to update 'Priority' field of service orders in a custom function module(remote enabled) and I have assigned this bapi to a custom business object. Also I have developed an ALE interface thru BDBG transaction which automatically generates custom basic idoc type,messsage type ,Ale i/b and o/b function modules.
Actually my requirement deals with a report where we have list of service orders in an internal table and pass each service order to update Priority field.
Is there any way to create an IDOC from the report and update the priority field and pass back the status of IDOC.
I have tried calling ALE O/B function function module generated thru BDBG transaction in my report but as a result i am unable to get any of the message whether idoc is created or not.
Here is my report code.

Get information about business object from view implementation class

Hi,
i´d like to develop some button behavior in a view. How can i get the information of the related business object like the order or the position. I like to disable buttons if specific status are set.
Bye Richard

hi,
Is needed field available in context nodes or not?
for example:
If you want to read STATUS_DESCR attribute from the context node SELECTEDDOC , then code like this
lr_selected ?= me->typed_context->SELECTEDDOC->collection_wrapper->get_current( ).
if lr_selected is bound.
lv_status = lr_selected->get_property_as_string( 'STATUS_DESCR' ).
endif.
activtae the debugging in IF_BSP_WD_TOOLBAR_CALLBACK~GET_BUTTONS method and check the values for context nodes and attributes.
I mean debugging for:
me->typed_context
me->typed_context->SELECTEDDOC
comp_controller

[WF Attributes] DDIC vs ABAP class

Hi,
I am having a hard time understanding which CL (ABAP Class) does not behave like DDIC structure.
I use both in my Workflow but I cannot manage to pass data (meaning reference) and trigger the Workflow
- from the FM 'SAP_WAPI_START_WORKFLOW'
- from an event
Am I forced to use the IF_WORKFLOW (I don't see why I have to use the FIND_BY_LPOR method ??) ?
-> if the static method FIND_BY_LPOR is returning the value, what has gone all the job in the first place ?)
I have simply created a customer-specific class that would avoid me adding new structure to the Workflow container and the Workflow Tasks again and again... simply extend the class and the element will all follow.
Many thanks in advance for your help.
Best regards,
Guillaume

Hello Guillaume,
I know this is closed but an interesting discussion nevertheless. The first part I am confused about is what exactly you are trying to accomplish and why:

Why can you not do this with a DDIC structure? I use this a lot. Particularly useful if you work with MOVE CORRESPONDING in your code. Just extend the structure and new fields are automatically transported (if they exist in the DB of course).
OO in WF is generally used in the same way as a BOR. The distinction is Business Object versus an OO class as you would use in an ABAP program.

As far as I know (and understand your point) it is not possible. Maybe someone disagrees with me, but I am happy to hear about that. The object instantiates itself whenever it is needed in the workflow. And during the instantiation you need to populate the attributes of the object, etc...
Correct, but.... if you are really determined, there are some tricks you can use: Who cares whether your object really exists in the DB, as long as your FIND_BY_LPOR always returns an instance. If this is always the same instance it can work. The thing to be careful of is that you MUST have an unbroken chain of tasks that execute in the same logon/RFC session. Once that session ends (e.g. by switching users/background tasks) the data is gone. Needless to say you need to know exactly what you're doing.

Calling Portal event from ABAP class

Hi Experts,
I need a following clarificatrion, Please help,
1. Is it possible to call a webdynpro method from a normal ABAP class?
2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
3. Is there any ways with which we can call portal event from ABAP class?
Thanks,
Shabir

>1. Is it possible to call a webdynpro method from a normal ABAP class?
I wouldn't necessarily recommend this approach. You shouldn't try to trigger events or any of the standard WDDO* methods from outside the WD Component itself. That said, you can pass the object reference (like the WD_COMP_CONTROLLER object reference or the View Object Reference) into methods of normal classes. Be careful if you are finding yourself calling a lot of your added methods from outside WD. This is probably a sign that these methods should be in the Assistance Class or some other Class functioning as a Model Object.
>2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
What exactly do you want to do here? Do you just want to get the relaxation script? For what purpose? You should never need to inject the relaxation script into WDA.
>3. Is there any ways with which we can call portal event from ABAP class?
To what purpose. Do you just want to delegate the triggering of the event that is inside WD Component to be called from a class? If so you can pass the portal API object reference into a class from the WD Component. However this only works while running within WD.
How is this class used? Are you running in WD? Are you trying to generate some HTML code that runs in the portal independent of WD?

Passing object references via methods

Why is the JFrame object not being created in the following code:
public class Main {
public static void main(String[] args) {
    Main main = new Main();
    JFrame frame = null;
    main.createFrame(frame); // <-- does not create the "frame" object
    frame.pack();
    frame.setVisible(true);
private void createFrame(JFrame frame) {
    frame = new JFrame("createFrame");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}Thanks.

These explanations are great; real eye openers.
OK. This could be a "way out in left field" question. I am just starting out with Java. But I want to ask:
Objects are stored in the heap?
Object references and primitives are stored on the stack?
Adjusting heap size is straight-forward. A larger heap can store more/larger objects. What about stack sizes?
C:\Dev\java -Xss1024k Main
I assume this refers to method's stacks. But, what about object scoped, and class scoped, object references?
public class Main {
private static List list = new ArrayList(); // class scoped
private JFrame frame = new JFrame(); // object scoped
public static void main(String[] args) { ...... }
private void createFrame() { .... }
}How is the reference to list and frame stored, with regard to memory management?
Do objects have stacks?
Do classes have stacks?
If not, how are the list and frame references stored (which helps me understand reference scoping).
Would the overflow of a method stack (ex. via recurssion) also overflow the method's object and the method's class stacks?
If these questions are stupid, "out of left field", don't matter, etc. Just ignore them.
But the knowledge could help me avoid future memory related mistakes, and maybe pass a "Java Certified Developer" exam?
My original question is already answered, so thanks to all.

Object references and array of integers

Hello,
Taking some java test, I came across the following question:
Given the below (UML) diagram, how many of the ClassA attributes will be object references when this class is implemented in the Java language?:
       ClassA                                         <<enumeration>>
                              ------------------->         Enum1
      var1 : int
      var2 : String                                         Elem1
      var3 : int[]                                          Elem2
      var4 : float                                          Elem3
      var5 : Double                                         Elem4
      var6 : Enum1   I answered 3, but the correct answer was 4. The one which I did not include was var3. Why will var3 be an object reference?
Thank you,
Mihai

That is true, my mistake. Arrays are object references (you do indeed instantiate an array by using the new keyword), but I was thrown off by what the array holds, namely primitive types, not object references.
Thank you,
Mihai

SES: Making Business Object 2032 searchable

Hello,
I tried to make the Business Object u201Ccustomer orderu201D (Bus2032) searchable with TREX 7.1 and ERP System 6.0, but the indexing failed.
I made what is described in the following thread:
SES - Making New Business Objects Searchable?
I copied the class CL_COM_SE_BUSOBJ_TEST_FLIGHT. So I had a class that implements the interface IF_COM_SE_BUSOBJ. Then I entered the Business Object and the new class in the table COM_SE_BUSOBJ, first with the transaction se11 and after that with spro.
But in the SES_Admin the Business Object has no title.
And when I tried to create an index with the SES_Admin the indexing failed with errorcode 000.
Can anyone help me?
Is it possible to make the BO bus2032 searchable? How?
kind regards
Ramona

Hi Ramona,
>> Is it possible to make the BO bus2032 searchable?
I do not see any reason, why it should not be.
If you followed the documentation and the linked SDN thread there must be some error in the details.
Please let me know, if I should hook you up with some SAP employed consultants to assist. Their service, however, may not be for free...
Best, Karsten

Field-symbols v/s Object references in OO-ABAP

Hi,
can anyone please tell me what is the difference between using field-symbols and object references in OO ABAP? Is there a specific need for field-symbols now that we have references?
Thanks.
Shakul.

Hi ,
Please note that both Field symbols & Object References are different .
You can use Field symbols during the following situations
1) When you want to modify the value of internal table, the field symbol would be useful since you do not have to use any Modify statement as in case of work area. The Field symbol works as a pointer and any changes to the field symbol will directly affect the value of the internal table
2) Make sure that you do not reassign the field symbol within a Loop iteration
3) Field symbols are useful when you work with dynamic internal tables ( tables whose structure is determined during run time)
4) After Read an internal table ( Read itab...) into a Field symbol, make sure you do a Sy-subrc check or check if the field symbol is assigned.IF not this will give you a run time error
You can use Object References while creating an object to a class. They are instances of a class.
Thanks,
Chakram Govindarajan
