How business object be used in such worst situation?

What I get from front end (thick client) is a large value object with undefined data type (data in vector or hashtable), it 's difficult to extract the data from the object in business logic layer. Eg. in gui, data managed in table, and I need to extract the data in the business tier, such that the business layer need to know the structure of front end data. It 's not make scense any more.
The worst case is I cannot control the data construction from front end.
So, I would like a data model to convert the data into business data (simple data).
But it seems not a best case.
So, any suggestion?

Thanks all,
actually, the problem is the incoming data has no
regular type.
The value object contains different data in different
situation.That still means it is ordered in some way.
One may be a hastable, one may be a vector and so on.
What the server (business tier ) need to do, is to
define a generic approach to obtain those data and
manage them into a systematic data without following
the front end component structure...That isn't possible. You must have some notion of the type of data. You can't decide to apply the business rules for a social security number to a zip code. Both have 9 digits so with out some other information about the context you can't tell them apart.
In the same way you don't want to save a vendor information in the customer table just because both look like address information.
I have tried to use a web service idea to apply on it.
Such that using a xml as a function descriptor. The
xml describe the server function(s) and the data
needed.
But I want to find a best way to solve it.
So, does anyone has experience on such work?
Let say swing application calling a server program via
rmi. The swing is a thick client with a lot of
functions and components. The server side handles
business function only.Do you control the GUI or not? If you do then you dictate how the GUI gives the data to you. If not then you produce a translation layer that converts the GUI format into a form that is usable by all of the other layers.

Save metada of Business Objects locally using JCO

Hi.
After retrieving the metadata of Business Objects, using JCO, (i.e. i have replicated the BAPI Explorer), I would like to save a particular Application Heirarchy Area & all Business Objects under it locally (e.g. Financial Acounting and all business objects under that area). I know there is a Save on the IRepository interface, but this seems to save all cached functions - that is not what i want ! Is there any way to save the metadata of those business objects using JCO ? Or should i just create my own Save which will save the metadata i want (to XML).
thanks
Javed.

Hello Javed,
to my opinion the best way to save the metadata, is to create your own xml structure. The methods save/load are only for handling the name of the repository and of the names of the functions and structures.

How Business Objects connects with Composite Studio 4.6.0

Hi,
Info on Composite:
Composite Studio is third party tool which connects to multiple data sources and executes the scripts (similiar to VIEW) to retrieve the results. One has to make call to the scripts to get the results.
more information: http://www.compositesw.com
Requirement:
Trying to connect BO XI R3.1 to composite as to call scripts to get data and then create Universe on the same.
Connectivity should be JDBC or oriented towards Java (preference for Java but not mandatory)
Tool: Composite Studio 4.6.0
Driver: composite46.dll
Driver location: C:\Program Files\Composite Software\CIS 4.6.0\apps\odbc
Regards,
Arjun Kushwaha
Edited by: Arjun_Kushwaha on Nov 12, 2009 8:43 AM

It will be great if you could let us know how to built the Universe on top of Composite, may be using ODBC connection.
I tried by creating the user / system DSN but these connections doesn't appear when tried to create the Universe in designer (using BO XI 3.1)
We can then try to build using JDBC connection.
The data source is very scattered and Composite is in the position to handle them all and hence we cannot eliminate composite and are forced to use it as one of the underlying layer to connect to actual data.

Problems with a Business Object when using data RAW.

Hi,
I've created a Z bapi with parameter tables as
FILE_BIN like SDOKCNTBIN
The structure SDOKCNTBIN has one RAW field.
When I go to SWO1 and implement a new Bapi, the following error occurs:
"Field SDOKCNTBIN -LINE is too large to be included in container"
Does anyone knows why when I declare an structure with a field RAW, gives that error?
Thanks in advance!

Business Objects are used basically to trigger other objects with the respective events like
1) To Trigger Workflows
2) To Trigger Events
3) Used to communicate with NON SAP Systems using BAPI's
4) To Trigger user define Business object we need to define the super type and need to delegate it with respect to the supertype so as to trigger custom business object which in turn triggers it event linkage objects whether it may be workflow or Event etc.
Hope this would help you.

Business Object Repository ( B O R )

Can some one please send me some data or links from where I can get data on Business object repository .

Hi,
SAP's Business Object Repository gives you an improved way to integrate business processes with external partners -- an increasingly necessary ability in the burgeoning e-marketplace economy.
The age of e has had a profound effect on the IT industry. Not only has it changed our way of life, but it has also forced systems such as SAP to embrace a new era of openness. Marketplace demands for flexible automation of inter-business workflow and intelligent data exchange have forced formerly very proprietary ERP systems to begin helping customers integrate with other companies and with e-marketplaces data formats. For the first time, companies must expose their business processes to the outside world.
In order to achieve this openness, SAP provides a technical infrastructure for the R/3 product, the Business Object Repository (BOR), which provides a simple yet powerful mechanism for external systems to trigger core business processes (such as placing an order) without concern for the underlying data structure. This level of abstraction is beneficial because it decouples R/3 from the external system. Either system is therefore free to change its internal business processes without affecting the other. SAP provides this technical infrastructure using a component-based view of its system. Each component or object provides a view of the data and the business processes that interact with that data. External systems can access this data via BAPI methods, which in turn access the underlying data structures of the system. It is the responsibility of the object and the BAPI to ensure the integrity of the data. This encapsulation of the data not only lends itself to external interfaces, but by using objects from within SAP, you can greatly reduce implementation, testing, and maintenance effort via the promotion of code reuse.
Business Objects
A business object is a problem-domain entity that you model in the SAP system, such as SalesOrder, BillingDocument, and Employee. The BOR stores all the objects in the R/3 system. The repository is a group of all the objects in the R/3 system. If the focus of objects is to model atomic business processes then it can be said that the BOR provides an enterprisewide view of business processes. By designing your ABAP code to fit your business processes you increase the ability of that code to flex when those processes are altered or integrated with external systems. This had made the object-oriented approach, which the BOR provides, essential to developing inter-business or e-business functionality.
Attributes
A business object is primarily represented by its attributes. You perform actions, such as create, update, or delete on the attributes by calling the methods of the object.
Attribute NetValue of Object BUS2032 (SalesOrder).
The majority of attributes are data-dictionary fields (for example, the NetValue attribute is defined by VBAK-NETWR). When you access an attribute of an object, you execute a SQL statement that retrieves the corresponding field in the database.
Definition of attribute NetValue.
You can also define attributes that do not exist in the data dictionary. These attributes are called virtual attributes. For example, a business partner has an attribute called BirthDate that is stored in the data dictionary. You can add a virtual attribute to the BusinessPartner object called Age. The age of a business partner is not stored in the database, but you can calculate it using the current date and the birth date of the business partner. If you implement the ABAP code that calculates Age, every time you access the Age attribute, the code executes and returns the business partners age.
Definition of virtual attribute Age.
This is an excellent example of one of the tools that a component-based approach provides. The external system does not need to concern itself with how to gather the data that it requires. The calling program needs only to access the attribute for the data to be returned. This is how business objects decouple the calling program (whether it be in R/3 or external to R/3) from the internals of R/3.
The BOR lets you define multi-line attributes. These attributes define one-to-many relationships between an object and other fields. These objects can be defined in the data dictionary or can also be virtual attributes.
An attribute that uniquely defines an object in the system is called a key attribute. In the case of a SalesOrder, the key attribute is VBAK-VBELN (the TableName and FieldName). It is not uncommon for an object to have several key fields. An example of this is object is the SalesArea (BUS000603) object type which has SalesOrganization (TVTA-VKORG), DistributionChannel (TVTA-VTWEG) and Division (TVTA-SPARTE) as key fields.
Methods
As mentioned earlier, the methods of an object represent the actions you take with objects attributes. An action in this example would include retrieving the status of one or more sales orders based on specific criteria. Methods are analogous to function modules in that they have importing and exporting parameters as well as exceptions, which you view by selecting a method and clicking on the toolbar button. This allows external systems (or internal developments) to pass and accept parameters from these methods just as if they were using function modules -- allowing external systems to call methods.
In Figure 4, the methods shown with the green LED are BAPIs that are called specifically from external systems. They can, however, be called from within the system itself. The method shown with the stop sign is obsolete, but retained for backward compatibility, and should not be used in new developments.
Methods of SalesOrder.
Delegation and Subtyping
One of the most complex concepts in object-oriented development is that of inheritance. This concept lets you extend core functionality by creating a child of the parent object that inherits all of its attributes and methods. For example, a Manager object is a subtype (child) of the Employee object. The Manager object has all the attributes of an Employee object (such as EmployeeID or Name) but also has some extra attributes (such as CompanyCar or ParkingSpace). SAP has not implemented inheritance in the BOR. However, it has provided subtyping and delegation, which offer an alternative way to extend R/3 functionality.
Subtyping
A subtype of an object is another object whose creation is based upon a parent object (see the preceding manager/employee example). The subtype maintains references to all the attributes and methods of its parent object. This means that any methods and attributes defined on the parent can be executed and accessed on the child object. I have often heard less-experienced developers refer to subtyping as copying the parent object. Although the effects can be similar, in order to achieve an understanding of some of the more advanced concepts, such as interface inheritance, it is important to realize that this is not accurate.
If a subtype object were merely a copy of its parent, then all the code contained within the parent would be physically copied to the child. This is not the case. The subtype simply maintains references to its parents methods and attributes. The real difference is that the subtype lets you redefine these methods and attributes. You can easily add your own business rules to the parent methods by redefining the subtypes method. In the following example, I will show why this distinction is so important.
Subtyping Case Study
As an ABAP developer at Acme Tyres Pty. Ltd., you have been given the task of implementing some security measures for the companys online store. The requirement is simple: The password must be at least six characters long.
Modifying SAP code leads to costly and complicated upgrades due to the modified code being overwritten by the newly delivered SAP code. Therefore, The challenge is finding a way of implementing the business logic without modifying SAP code.
After some investigation, you realize that the method CHANGEPASSWORD (in BAPI) on the object KNA1 (Customer) is called when customers change their passwords. All you need to do is create a subtype of KNA1 and then redefine the CHANGEPASSWORD method adding the ABAP code to ensure that the password is a minimum of six characters long. It is of course not wise to change SAP code even assuming you have the passwords, which can be provided only be SAP. After the method is redefined, you just need to implement the business rules in ABAP.
FIGURE 5 Redefinition of ChangePassword method.
It is imperative that once you redefine the method it still behaves in a similar manner. You are allowed to add extra business logic, but the method must still change the password rather than do something unexpected, like delete a customer. This is particularly important when SAP is being accessed from external systems. The external system will expect a method to provide certain functionality. The developer should take care to ensure that this expectation is met.
Delegation
Now that you have implemented a new CHANGEPASSWORD method, you need to tell the SAP system to use the redefined version of CHANGEPASSWORD and not the version that was delivered on the KNA1 object. This is similar to object-oriented inheritance but the two concepts do have fundamental differences.
Delegation for objects.
By making an entry in the delegation table, you tell R/3 that before executing a method on KNA1, it should first check if that method has been redefined on the subtype. If it has, then the system executes the redefined method . If it hasn't, then the system executes the original method. Figure 7 illustrates this process.
Execution flow for methods with delegation.
This delegation is powerful because it lets you implement your own business logic without modifying any SAP code. As long as the objects are properly delegated, your method will be executed.
Responsibility
So far I have shown you two major components of an object, its attributes and methods. The difficulty in SAP is that it has traditionally been a data-driven, procedural-development approach. The BOR is not well understood by developers and managers and thus it is shunned by those that stand to gain the most from it. If managers and developers alike would take a formalized approach to development using business objects, significant savings in the development, testing, and maintenance phases would be achieved. This is due to the high level of re-use that business objects encourage.
Having said this, when a powerful tool is put into the hands of an inexperienced person, chaos can (and usually does) ensue. If object-oriented design principals are not adhered to, then the resulting code has poor reusability and maintainability. Although an in-depth discussion of design issues is beyond the scope of this article, I will introduce in the following section one of the more fundamental design aspects of BOR programming: Responsibility.
When you are given the task of creating a method or attribute on an object, one of the most important questions you should ask is, Does this attribute or method belong on this object? This question is fundamental to an object-oriented design and the answer can make a world of difference. Answering this question incorrectly has detrimental effects on the development effort resulting in methods and attributes strewn across myriad objects, with no coherent structure. If the methods and attributes were strewn across several objects, it would be more difficult to provide a uniform interface to external systems. If an external system wants to execute a particular business process in R/3, it may need to access several business objects, thus increasing coupling and reducing the layer of abstraction between R/3 and the external system.
Lets take, for example, the requirement to be able to update a sales order. This is a common requirement and one that SAP usually implements for you. For the sake of the example, lets assume that SAP has not implemented this method. You will need to implement your own UPDATE method on one of the business objects. The question here is: Which object? This question is what I term as defining responsibility. Which object is responsible for having the UPDATE method on it? As shown in Figure 4, the answer in this cases is BUS2032 (SalesOrder). If you put it on any other object then you run the risk of no one else knowing of its existence. Next time there is a requirement to update a sales order, the developer will develop an additional method. You would then have two separate pieces of code that implement the same functionality. This duplication doubles development, testing, and maintenance requirements. On large projects, this can become a real problem and a maintenance and testing nightmare.
SAP recognizes the challenges facing developers in the e-business era. It is aware that if it wants to take R/3 to the next phase, it needs to continue evolving the ABAP language and ensure that powerful development tools are available to SAP developers.
Rising to the challenge, SAP has begun developing extensions to the ABAP language called ABAP objects (see "Introducing ABAP Objects," in the IntelligentERP feature archive for an excellent introductory article to ABAP objects by Jürgen Heymann and Horst Keller). These extensions will provide ABAP developers with a full range of object-oriented tools. Eventually, these new extensions will make BOR obsolete. However, the use of object-oriented development is sure to be an integral part of future SAP developments, regardless of where the world of e takes us.

Business Object linked to application document

hi All,
Is there any standard tcode or way to find out a given business object is linked to what all application documents?
Like for example i would like to know BO FIPP is linked or can be used for what all documents or tcodes??
How can find out??
Thanks in advance.
Regards,
Raj

Hello Raj,
this is indeed a sad thing, not having a control table that links transaction codes to objects or classes. The GOS-Integration (Generic Object Services) are implemented within each transaction and usually the business object types used there are hard coded.
You can have a look at the where-used-list of ABAP class CL_GOS_MANAGER. You'll find an example here, include LMEORF1M at form routine bus2053_object_publish. There you'll see the common way of how objects are used/published.
Furthermore, the event creation/handling is also usually hard coded.
Not all transactions that make use of business objects, also use the GOS. So you'll always get a part of this.
You can also have a look at the where-used-list of Business Object Interface IFGOS.
Best wishes

Business ByDesign UI: find Business Objects and UI definitions involved

Hello,
I am new to SAP Business ByDesign sdk development. The most difficult part is to identify the right Standard SAP Business Objects and use them the right way.
As I understood from another sdk developer, he has seen on an SAP sdk training that there exists functionality to see/determine in the ByDesign UI the Business Objects and UI definitions involved in a specific UI.
In a test tennant for a customer this functionality is unavailable.
- is this functionality released for customer use?
- how can I activate this functionality myself?
- what are the prerequisites to be able to use this functionality?
thank you for your answers in advance,

Business objects and event type linkages...

Hi Experts,
Im a bit confused with business objects (swo1) and event type linkages(swetypv). Ive learned that business objects are used to trigger events and so how does event type linkages related to business object? Do I need to create business object or should I just search/look for the appropriate object needed?Please kindly explain to me the process or steps in using business object and event type linkages in related with idocs.

Hi,
Business objects neednot have to be created if your are fine with the standard method they have used in or the events yre available for you. If you need to cusomize it then you have to copy it to a subtype. Then do your modifications in it. Event type linkages are used to say which event is active for a Workflow. And if you want to trigger a Workflow based on certain conditions then you have to use either this or Start of Condition. The Error handling of workflow is also handled by Event Type Linkage. So whenvever you create a event linkage for a workflow you get an entry in Event Type Linkage.
Hope this would have thrown some light on you.
Thanks,
Prashanth

Link Between Business Object and Transaction

<b>How is Business Object linked to transactions?</b>
For example, how is business object BUS2032 (Sales order) linked to transaction VA01 (Create sales order)?

Hi Ben,
I'm not sure that you link a business object and a transaction code explicitly. Normally in the business objects methods you have coded what transaction code should be called. Therefore if you use the methods of the business objects it then knows what transaction to call.
Conversely on the workflow side you will find that down in the depths of the coding for VA01 (as an example) it calls workflow function modules and raises events. When doing so it provides the business object id and key to the business object (i.e. the sales order number). Indirectly I guess the change documents that are raised for most things in SAP like sales documents are uniquely identified and therefore can also be translated to the business object key (e.g. sales documents will have their own change document type).
A brief example in my 4.6c system can be found in include LIEDPF4C in the form finsta_kontoauszug_buchen with a call to function SAP_WAPI_CREATE_EVENT. You see the the parameter "object_type" has a variable passed to it "objtype_finsta". If you drill back on objtype_finsta you see that is hardcoded to the value BUS4499.
I guess you could say the developer of the business object knows what transaction codes the business object should use and the developer of the code in the transaction code knows what business objects he should be raising events for if necessary.
Hope this helps.
