Seperating business exceptions and System exceptions

Hello All -
We are developing couple of mediated services using SAP PI 7.0. Below is our requirement
1.When the service producer indicates a business exception (it might be either a SOAP fault or error code coming as part of SOAP body) , it should be converted as BusinessException before throwing back to the consumer
2. When the service producer indicates a System exception (it might be either a SOAP fault or error code coming as part of SOAP body) and there is a system failure in SAP PI, it should be converted as System Exception before throwing back to the consumer
My previous experience was with IBM Process Server, where it allows to do this. Can I achieve the same with PI 7.0
Thanks in advance
Rajeev

Hi Milan-
Thanks for the reply. We are not using bpm, since one of our expert told us that it can be a performance overhead.
Is bpm the only solution for implementing this way?

9.3.3 Upgrade, null pointer exception when accessing business rules and mac

Hello,
We upgraded from 9.3.1 to 9.3.3. In the Essbase Administration Services Console, when I attempt to access business rules or macros from a client PC, we get a null pointer exception. The message does not tell us much, but I cannot find more.
I can access business rules and macros using EAS Console from the server. Do I have a bad installation, or have I missed a step?
Thank you,

Hi,
You might have to re-organize your application module hierarchy to place your common code.
If your intension is to auto populate the primary key for your Entity Objects., I would suggest below common practice.
1). Create a Base Entity Impl class for your project that extends oracle.jbo.server.EntityImpl
2). Code your getDbSequence() method inside this base entity impl class
3). Make sure that all your Entity Objects extend your base entity impl class
4). Use EL expression to call this method for auto-generating primary key attribute of your Entity Object.
e.g., adf.object.getDbSequence("sequenceName")

Throwing Business Exception from Human Task

Hi,
Can anyone point me to some examples, of how can I configure a Human Task to throw a business exception in a BPMN process ?
I want to provide th user with the ability of completing the task normaly, or launch a business exception like, cancel the order, or lack of stock.
I'm using Fusion 11g.
Thank You.
/RG

Hi
Thanks for the reply. But, I'm not sure I understood you correctly. What I want, is not to capture an exception after a human task, but to generate one in it. I want to add an error boundary event to a human task. The user can fill the form normally (for example a purchase order) and the normal flow continues or he can generate an exception (like cancel case, or lack of stock) that will be cought by the error boundary event.
What I want to know is how can I generate a business exception inside a human task? For example in the interface.
Is this the right way to do it ? Am I missing something ?

Handling business exceptions from DB adapter

Hi,
How to handle the business exceptions/faults raised from PL/SQL stored proc exposed via DB Adapter. From what I know there are two types of exceptions namely business exceptions which result into binding faults and runtime exceptions. The later are retriable exceptioons.
So the scenario I am working with is a simple PL/SQL procedure which selects from a table and returns a value if found and raises an PL/SQL exception if select fails. I expect the second case to result in a binding fault and hence catchable in BPEL process or ESB as error topic.
But when I try this I am always getting oracle.tip.esb.server.common.exceptions.BusinessEventRetriableException. More over as the name implies it's a retriable exception and it appears to me it's being re-tried by default before throughing this message. My question is shouldn't this be a business fault/binding exception?
Am I doing something wrong here? What's the expected behavior for exceptions (buiness related) raised from DB adapter. I understand I can always catch these exceptions in PL/SQL and pass a relevation status OUT parameter. But I am trying to mimic a typical input/output or input/fault type of web service interfaction for PL/SQL procedure.
Any help is greatly appreciated.
Regards,
Rajesh

Just my 2 cents, but you're talking about the integration of DB Adapter and ESB and I think Marc is talking about Bpel and DB Adapter and these have different functionalities for eror-handling.
In ESB a framework has been added to be able to retry exceptions that are 'retryable business exceptions', which gives the user the possibility to for example recompile the procedure/function and retry the transaction that was defined earlier.
I think if you want to add custom exceptions you will need to extend the BusinessRetrievableException to your own custom exception handling.
I think this is a possible enhancement question for the exception handling-architecture that has been created for usage in ESB. Maybe this can be added to the 'enhancement requests for ESB'-list ... if that exists?

Business Exceptions - BPEL

How to call a business exceptions through BPEL? Are we supposed to define a custom handler and call this through any activity ?
Pls respond if anyone has done this in projects...thanks

Importing RuntimeFault.wsdl is not required.
You need to model your projects wsdl to include business fault
Roughly I can put steps here
1.Define xsd to hold business fault content
2.Define message in your project wsdl pointing to Fault element in above xsd
3.Define operation in your project wsdl which includes fault
Example:-
<wsdl:operation name="GetEndorsingBoarder">
<wsdl:input message="es:GetEndorsingBoarderRequest"/>
<wsdl:output message="es:GetEndorsingBoarderResponse"/>
<wsdl:fault message="<prefix:messagedefined in wsdl>"/>
</wsdl:operation>
No I think you should be able to find fault from Throw /reply activity
Let me know if it works.

Business service and business system

Can someone please tell me what is the difference between business service and business system and in which cases are they used respectively?

Hi,
Business System
Business System have an entry in the SLD and Buiness Service do not.
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.

Business Services and Business System

What is deffrence between Business Services and Business System. Which type do I have to choose for File,JDBC,SOAP Receiver/Sender?

Hi Denis,
Please go through this link, it has all:
http://help.sap.com/saphelp_nw04/helpdata/en/7d/6b82cd0d1aef48ab5953524c9cc5b2/content.htm
Choice depends on which form of integration your are doing. Service is a Abstract unit for adressing senders or receivers. It is used mainly for test purposes.
But in real time the data can come from any system in the landscape, therefore they all should be in your SLD.
Sceanrios involving these third party of other SAP systems need to use Business System in their integration scenarios.
I hope if it helps, you'll give me points )

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.

element EP_VAL2 : LANGUAGEINDEPENDENT_MEDIUM_Text;
element IP_RES : LANGUAGEINDEPENDENT_MEDIUM_Text;
I have created the Web Service using this custom business object.
3) How i can use this web service in external system? what are the prerequisite steps in external system to consume this service in it?
Please anyone have idea about this how to do this and how to achieve this using SDK and custom business object.
Many Thanks
Mithun

Hello Mithun,
Does this section in the documentation help you:
SAP Cloud Applications Studio Help -> Developers Desktop -> Web Services
The entry "Task -> Create a Web Service" describes how to create a Web Service on your own BO
The entry "Task -> Test a Web Service" helps you how you can use it in a foreign tool / application.

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..
