Business Logic and Business Rules

Hi,
I have a very basic question. If we develop a new screen on top of ECC using Webdynpro ABAP to replace a ECC default screen, say for an example, ME51n screen for purchase requisition to be replaced by a custom screen developed in ABAP Webdynpro, then how do we incorporate the inbuild business logic and the business rules of me51n in to this new screen developed in ABAP Webdynpro? In short, how do we incorporate business logic and rules in to ABAP Webdynpro application?
do we have to code all the logic from scratch or we can use existing logic? If we can, how.
Thank you for your help.

How can I use JTA in my business logic and execute process with PAPI?

HI All,
How can I use JTA in my business logic and execute process with PAPI?
When my business logic has exception, the process will rollback.
or the process has some exceptions, my business logic also will rollback.
I don't know how to do it.
Does anyone know how to do it?

Thank you for your reply, Daniel.
But I think I did not express my mind clearly.
There is a scene that I have 2 Application Server.
My business code is deployed in one Server.
The BPM is deployed in another Server.
I want to execute Task use PAPI.(ProcessServiceSession.runActivity)
In my business code, I will do something before execute Task.
I need my business logic and Task in same transaction.
To ensure them "all-or-nothing" .
As you say, if The transactions are managed by Oracle BPM.
then can I retrieve OBPM transcaction in my business code?

Java for business logic and CFMX for GUI?

For those familiar with ColdFusion MX, does it make since to use Java at the business logic and possibly data tier and have CF handle the GUI?
What are the advantages/disadvantaes (methology, threading, memory use, performance, etc)?
Thanks,
Brett

I can't think of any advantages to doing this except that you won't have to listen to people whine about learning something new. Go with Java Server Pages and Servlets to split this functionality. Once you get over the learning curve, you will be much happier.

Diff between Business service and Business System?

HI Experts,
Pls let me know wht is the difference between business service and business system??
when we will have to go for business service and when for business system??
thnx in advance..
New XI

Hi,
Difference between Business Service and Business System are :
1) Business sytem require all details like login user id
password require to create but in case of business service
log in details does not require..
2) A Business System is purely for SAP-Systems and
Business Service for Non-SAP systems
3) Business service refers to any business applications where
as the business system is defined in SLD(System Landscape
Directory)
4) When we have full details of application system the we are
going to use the business system and it is created in the
SLD so we dont have authorization to change the business
system name.
When we have partial details or no details of Technical
system then we r going to use the business service. it is
created in the ID. we can see and change it.
5) A Business system is something that physically exists
For example, if u want to download a file from a system
ABC, by using file adapter and then want to update the
content of this file into r/3 database by using RFc,then
the system abc and the r/3 will be ur business systems
i.e. they physically exists. Business Systems are
configured in SLD.
Business service is mostly usedin B2B Scenario (cross-
component),where you don't know the Business System of your
partner. In other words business Service will be used only
for those partners which do not have a physical landscape
set up . Business servces do not have an entry in SLD.
6) A Business Service is an Abstract Unit(which is not in
System Landscape Directory) addressing Senders and
Receivers of Messages.
Physicals systems which use their communication channels
and routing rules to communicate with other systems are
called as Application Systems OR physical systems.
7) In simple when u going for A2A integration then we define
our Technical systems are Business system. If we r going
for B2B integration then we dont know the complete
information about the other end Business Landscape so, we
configure it as a Business Services. Business system are
created at SLD. Where as a Business Services are created at
Integration Directory.
8) Business systems:
These are logical senders or receivers that exchange
messages by using the Integration Server and that are
entered in the System Landscape Directory.
The business systems in the System Landscape Directory
relate to a system landscape. The business systems of
business partners are therefore not entered in the System
Landscape Directory. To be able to address such business
partners logically, use communication components in the
Integration Directory. A business system is a way of
specifying a communication component in the Integration
Directory more precisely (business system component).
Hope this will hwlp u..

Business Systems and Business Service - does any difference

Hi Experts,
Could any one please guide me what is the difference between
Business Systems
and
Business Service.
Which situations we use Business Systems / Business Service.
Does it have any performance issues?
Why we are not configuring Business service in SLD?
Cheers Experts!!
Sunil

Hi Sunil,
Business System: Address a particular business system as the sender or receiver of messages.
A business system is an actual application system in a system landscape. A business system
(service) comprises information about the inbound and outbound interfaces and the software
component versions of the business system. The business system services are used when
configuring internal company processes.
Business Systems are Logical Senders or Receivers that exchange messages by using the Integration
Server and that are entered in the System Landscape Directory.
The Business Systems in the System Landscape Directory relate to a system landscape.
The Business Systems of business partners are therefore not entered in the System Landscape
Directory. To be able to address such business partners logically, use communication components in
the Integration Directory. A business system is a way of specifying a communication component in the
Integration Directory more precisely (business system component).
Business Service: Address an abstract business entity as the sender or receiver of messages.
Using a business service, you can define the technical or business subunits of the companies
involved and then assign them the relevant interfaces. The business services are used when
configuring cross-company processes.
In the PCK, the Service is of type Business Service. It represents an abstract, addressable unit.
Business services are used in cross-company processes, for example, if the parties involved have only
published their interfaces and not their system landscape, or it is only partly known.
Using a Business Service,we can define the technical or business subunits of the companies involved
and then assign them the relevant interfaces.
It is useful to use Business Services when configuring cross-company processes. Usually, the
interface descriptions of the business partners involved are made publicly available.
Also,There is already lot of thread regarding the same discussion, please see it below.

Business Systems are used when you are sending data to and from an R3 system and can be of ABAP, JAVA and Third Party Types.
Business System is a logical representation of a Technical System.
Business Service :
Business Service is a abstract representation of a System. For instance, www.google.com have a several system working together and IPs of this machines change eventually. When we use a Business Services like google we reference a computer that we don't know the phisical implementation.

Difference between Business system and Business service.

Hi All,
Can any one explain in detail difference between Business system and Business service.
As we commonly say, Business service is for those system which are not in our landscape.
Can any one explain in which particular scenarios we will go for Business Service.
Reg
Bapuraj

Hi Bapuraj,
Business System
Business system is a logical system, and there is an importance on physical existence of the system.Also SLD entry is required.
It is generally used for SAP applications, this is just a general prinicple followed but not mandatory.
Business Component(formerly Service)
You use a Business Component, when you do not have the System details of the the partner system to which you want to communicate. i.e. you have not configured the partner system in SLD.
Business Service is an Absract Unit with Sender and Receiver Interfaces,In this case you need to explicitly add the message interfaces while doing configuration in ID.
It is generally used for NON-SAP applications, this is just a general prinicple followed but not mandatory.

Hi,
Can anyone tell me the difference between Business service, Business system and Business process?
Thanks,
Harikumar. S

Hi,
Business system
It is a logical system from a business point of view.
One or more logical systems that belong together from a business point of view is called a group of Business system group. A business system group represents a unit within a company or organization that can be defined according to legal, economic, administrative or geographic factors.
The objects in a business system group are uniquely identified by a uniform numbering system.
Business process
Business procedure within an enterprise that uses resources and can involve activites from a number of different cost centers in a controlling area.
When executing a business process, activities can be utilized for several cost centers of a controlling area.
Business service
Its a third party system.
All these belong to a Business Scenario which is
Description of the flow of business processes according to a business typology. A business scenario represents a template for a business process, which runs within a particular area of a company process. All processes required to completely process the task are listed in chronological order in the scenario. Business scenarios can be described graphically, in either aggregated or detailed form (EPC).

Difference between business service and business system in SLD

hi all,
i m very new to XI. can anybody tell me that what is the basic difference between Business Service and Business Systems?
Is it necessary to use them? and if yes then when to use what?
Thanx.
Regards,
Kunjal......

Hi Kunjal,
In SAP XI every system in your landscape with which you are interfacing is defined as Service.
The service can be your Business service or Business system.
Generally SAP systems are referred to Business system and you define them in the SLD before you import them.
The Business service is a logical name referring to any system in your landscape.
To communicate with any third party application you need to create communication channels which are associated to your service.

5(Business systems refers to the physical systems, for instance the R/3 system. You define the business systems in the SLD
Business Service
1) You use a Business Service, when you do not have the System details of the the partner system to which you want to communicate. i.e. you have not configured the partner system in SLD.
2) Business Service is an Absract Unit with Sender and Receiver Interfaces,In this case you need to explicitly add the message interfaces while doing configuration in ID.

Regarding Business System and Business Service

Hello,
What is the difference between the Business system and Business service. When do we go for what? Which system we will take as business system or business service means either sender system or reciever system.
Give me with simple example... please
Thank you

hi,
What is the difference between the Business system and Business service.?
Business System is a logical representation of a Technical System.
Business System: BS is a conceptual representation of a logical system, such as a specific client on a SAP server or a 3rd party payroll application.
For defining Business Systems, the four important pieces of data are:
u2022Business System Name (must be unique in the landscape)
u2022Associated Technical system name, and if the Business System will be used with IDoc interfaces, a Logical System Name
u2022The Software Products (and associated SWCVu2019s) that are used by the Business System. The products are brought through from the Technical System definition; but for a particular Technical System, not all products will necessarily be associated with a particular Business System.
u2022The Related Integration Server.
A Business System addresses a business system as a sender or receiver of messages. Unlike an abstract service, a business system represents a specific (application) system in the system landscape. A business system (service) comprises information about the inbound and outbound interfaces and the software component versions of the business system.
Business Service is a abstract representation of a System. For instance, www.google.com have a several system working together and IPs of this machines change eventually. When we use a Business Services like google we reference a computer that we don't know the phisical implementation
Business Service: Address an abstract business entity as the sender or receiver of messages.Using a business service, you can define the technical or business subunits of the companiesinvolved and then assign them the relevant interfaces. The business services are used whenconfiguring cross-company processes.
Which system we will take as business system or business service means either sender system or reciever system
Business system and business service can either be a sender or receiver...
business systesm is an application system which is a real system..business service is an abstract entity...we send requests using webservices for them....

Hi all,
I'm new to XI. I was asked two questions. Any one answer the following, plzz.
a) Difference between Business System and Business Service
b) Difference between Technical System and Business System

Hello Gopi,
a) Business System is a logical representation of a Technical System.
Business Service is a abstract representation of a System. For instance, www.google.com have a several system working together and IPs of this machines change eventually. When we use a Business Services like google we reference a computer that we don't know the phisical implementation.
b) Technical system is a phisical machine, it have a IP. Can be a BBDD, ERP, J2EE ......... a Business System is a logical term that we use into the Business Scenarios and represent these Technical System that we had created.
Hope it's help you
