OHS to B2B Communication

I have a question from the design point of view. We have Trading partner sending POs by invoking B2B Web Service. The question is when the HttpServer receives the web service call and forwards the request to the B2B server, if for some reason the HttpServer is not able to connect to B2B server, or any other reason, is there a possibility for silent failures, in the sense, the PO is lost and the trading partner getting SUCCESS or no error message back???

Hello,
Good question, To my knowledge both of these communication happens as part of a single transaction. I shall confirm the same.

B2B communication using PI

Hi all,
I want to know what exactly is the meaning of B2B communication and A2A communication.How are both of them different?
How exactly does the concept of "Party" help to establish B2B communication.
Many Thanks,
Neha

Hi Neha,
You already have the best answers from the Gurus. Only to add to answer the second part of your question,
"How exactly does the concept of "Party" help to establish B2B communication."
In a scenario Party object designates an Organization or a similar entity (Business partners/customers or the Home Organization) taking part in the scenario.
Using Parties in a B2B scenario in XI helps to define the logical scenario between the transacting parties........where you use the Services under Parties.
While in A2A you should use Service without party, as the transaction takes place between Business (Logical) Systems defined within your System Landscape (SLD).
Now how technically the Party object helps to establish B2B communication...............
While configuring IDoc scenarios and the IDoc partners for these transactions are defined as Vendors (LI) or Customers (KU) in the Backend R/3 systems,
then the Inbound IDoc adapter resolves the Sender/Receiver information (SNDPRN, SNDPRT, RCVPRT, RCVPRN) in the IDoc control header to a specific Party object in the configuration during Normalization, using Party Identifiers.
And reversely the Outbound Idoc adapter resolves the Party objects used in XI scenario into the Backend R/3 system's Idoc partner while creating the Idoc Control header Information.
Also the Party Identifiers (Alternative Identifiers) are used to convert the Party names used in XI scenario to Multiple globally-recognized identifiers for Companies
(Such as DUN numbers or EAN codes) - which directly relates to (facilitates) a physical cross-company process/transaction - in the message header.
Some useful excerpts from help.sap.com
A communication party (party for short) represents a larger unit, which is involved in a collaborative process.
Using a communication party, you generally address a company within a cross-company process.
You can assign a communication party one or more services to address it as the sender or receiver of messages.
Alternative identifiers are used as follows at runtime:
· Inbound Processing:
If a message from an external party contains an identifier for a company in the message header, the identifier is mapped to the name of the internal party (normalization).
Only then can the relevant configuration objects required for the message to be processed further be found and analyzed in the Integration Directory.
· Outbound Processing:
The internal party name of an outbound message is mapped to the identifiers to be used (in accordance with the configuration settings).
The external receiver then receives a message that contains the externally-valid identifier in the message header (denormalization).
Wish you the best in developing your first B2B scenarios

Suggest basic scenario to demonstarte B2B communication feature using BPEL

Hi All,
I want to show Basic B2B communication feature using BPEL. I am new to B2B and trying to learn it.
Can anyone please suggest a simple scenario that a newbie like me can implement. Or can please send me a sample implementation with description.
It will help me a lot.
@Anuj : I am not able to download the 2nd part of the B2B document editor from the link you mentioned in you blog. Can the document editor be downloaded from edelivery....if so can you please send me the link.
Thanks in advance.
Jignesh.

Hello Jignesh,
Oracle B2B samples are available here -
http://www.oracle.com/technology/sample_code/products/b2b/index.html
Are you not able to download document editor from here -
http://www.oracle.com/technetwork/middleware/downloads/fmw-11-download-092893.html?ssSourceSiteId=otncn
You may download it from edelivery as well. On edelivery, select "Oracle Fusion Middleware" as product pack and windows as platform. From results select "Oracle Fusion Middleware 11g Media Pack for Microsoft Windows (32-bit)" release 11.1.1.3.0 and click on next. Here search for "Document Editor" and download all four parts (edelivery has document editor in four parts)
Let us know in case you find any difficulty anywhere.

Party in a b2b Communication.

All,
I am currently involved in getting a naming conventions document for a landscpae that has more B2B scenario.
Think of B2B and the first think that comes to mind is "Party" . I know you create the Party in the Integration Directory and then add the Name Scheme and Agency to this and do your corresponding configuration.
Now, the point I am stuck in,
1. Transportation of Party's?
When you transport the Configuration Objects from one landscape to another (frm Dev to QA and prod), is it possible to change the name of the Party?
Is my assumption that just as Business Services are created in the Directory and cannot be renamed as you move across landscapes , that Party also cannot be renamed and so the names of these party has to be independent of the landscape ( we plan to suffix the name of the Buss System with _Dev , _QA and so on).
2. Renaming of Agencies inside the Party?
Now, inside the party we give the name of our Business Systems / Services for the corresponding Agency. As we move across environments, is it safe to assume that the names of the Business Systems will be changed against Agency as well if the SLD level transport targets are created correct?
Thanks in advance,
Regards
Bhavesh

> 1. just like I said - there's no landscape suffix in
> party (like dev etc)
Thanks. Partial Problem solved and my understanding was correct.
Question 2 as well I think the renaming will / should happen for Agency , maybe someone has done this and has the exact answer.
Will wait
Regards
Bhavesh

SAP to non-SAP Communication Using Proxy Framwork

Hi all,
While searching for the connection option for the B2B collaboration between SAP and non-SAP business system, i found that there are two ways we can do it.
One using Adapters and another using Proxy Framework.
In our case We are on SAP Enterprise and non-SAP business partners are using I2, legacy system.
They are not using Rosettanet PIPS, so I can not use RNIF or any other adapter for the inbound or outbound operation.
My question is If we use proxy framework, what needs to be done at the non-SAP business system . Do we need to install proxy runtime and how does this proxy runtime will communicate with the application in non-SAP system.
Thanks in advance

Hi Ruby,
You can use proxies for communicating with ABAP 6.20 systems and above and for J2EE applications.
For B2B communication you would normally use an adapter for example plain HTTP, SOAP or RNIF ...
An alternative is to install the XI PCK on the partner side. The PCK is essentially a standalone version of the XI Adapter Engine installed locally at the partner. This enables a scenario where XI communicates with the PCK over HTTP and then an adapter (file, JDBC ...) is used to communicate with the legacy system and vice versa.

B2B integration with just one trading partner using a dedicated VPN channel

Hi colleagues,
We are working in a B2B integration escenario, where our company will just integrate with a service provider using a dedicated VPN channel, so we won't go out to internet, for that B2B communication we have identified 10 inbound + 9 outbound interfaces.
Do we need to look into implemeting an document exchange protocol for that? Of course we need some ACK mechanism as there'll be SLAs in place. If so, what would it be the most appropiate? I've been reading about ebxml, rosettanet etc but still not very clear for me which level of customization you'll need in order to apply those protocols. If this is much and given the fact that we are just dealing with a trading partner and we won't scale this platform to use more parther in the future, would it be worthy to customize our own ACK mechanism?
If relevant, in our side we use oracle fussion middleware, the trading partnel is using SAP IS-U. The message format will be standard XML, we haven't identified the need of any other formatting at the moment such EDI.
I know this is a very open question, so any advices or recommendations on that are highly appreciated.
Regards,

Hello Dipal,
There is a lilttle catch. Eventhough your Delivery channel which is used in the agreement for a specific trading partner specifies some IP/Port, you can dynamically send the message to some other IP as well. This is specified in the document.
This will give a flexibility of sending the HL7 message not just to the end point which is mentioned in the agreement but also to any othere ip/port as driven by the ACTION_NAME field in the IP_MESSAGE type. However ACTION_NAME filed overrides the delivery channel information, hence at any point of time you can
1. Send a message to the end point mentioned in the delivery channel and used in the agreement. In this case ACTION_NAME is null or
2. Any dynamic end point driven by the ACTION_NAME.
Hope this is clear.

Transactional Behaviour of Oracle B2B 11g

Hi Gurus/Anuj,
Can you please explain Transactional Behaviour in Oracle B2B 11g?
For a Inbound Interface I have three Mediators(Mediator M1,M2 and M3)
Partner push a file at file location --> B2B Interface used in M1 ,through B2B Binding,picks the FIle and brings to SOA and--> Give it to M2 and M3.
I need to perform Error Handling in this case..
M1 M2 and M3 are Asynchronous,Synch and Synch in nature and I guess M1 will propogate it's transaction to M2 and M2 will propogate it's transaction to M3.
Routing rules are Sequential..
Note : Fault policies are applicable to parallel routing rules only. For sequential routing rules, the fault goes back to the caller and it is the responsibility of the caller to handle the fault.
Am I correct in understanding that :
B2B Adapter in M1 is the caller and M2 and M3 ,as being Synchronous,will follow M1'a transaction.
And if a Fault goes into M2 and M3,it will go back to the caller,means M1.
And in M1 we can have Fault-Handling.
Also please explain Transactional Behaviour in Oracle B2B 11g?
Is B2B is Asynchronous in nature?
Is B2B Adapter a Transactional Adapter?
What category of JCA adapter is Oracle B2B adapter?
Thanks

Hi Vivek,
Also please explain Transactional Behaviour in Oracle B2B 11g?Oracle B2B depends upon the underlying transport being used for transactional behavior. As far as transaction propagation is concerned, we never had any such need in B2B communication.
Am I correct in understanding that :
B2B Adapter in M1 is the caller and M2 and M3 ,as being Synchronous,will follow M1'a transaction.
And if a Fault goes into M2 and M3,it will go back to the caller,means M1.
And in M1 we can have Fault-Handling.If you are using AQ interface of B2B adapter with XA Data Source then that adapter can participate in an XA global transaction that can span multiple resources. In this transaction, the application server acts as the coordinating transaction manager with multiple databases (or other resources such as JMS), each of which is involved in a single transaction.
If you are using JMS interface of B2B adapter with XA Connection factor then that adapter can also participate in an XA global transaction that can span multiple resources.
If you are using Default (Fabric) interface of B2B adapter then it does not participate in global transaction, rather it starts it's own local transaction and executes in that. So it will totally depend upon the interface you are using with B2B adapter that it will start and propagate a global transaction or will not participate in a global transaction. Moreover, if B2B adapter is starting a transaction and propagating it to a async service then that sync service will start a new local transaction and further sync services may execute in that transaction. As soon as the control comes back to B2B adapter, it will commit the transaction.
Is B2B is Asynchronous in nature?B2B can be used for both sync and async calls (between partners). B2B is async when communicating with middleware.
Is B2B Adapter a Transactional Adapter?Explained above
What category of JCA adapter is Oracle B2B adapter?No special category. It is a specific adapter for Oracle SOA SCA composites to facilitate them in communication with Oracle B2B. You may or may not use this adapter in SOA SCA composites.

Mix B2B and A2A in integration scenario

Hello XI experts,
I'm trying to build an integration scenario in the repository that I want to import later on into the directory for automatic configuration.
The scenario is HTTP -> XI -> RFC. On the sender side I would like to use a business service, so I selected 'External party with B2B communication' for the sending application component. On the receiver side I would like to use a SAP business system, so I didn't select that option there.
Now, if I import into the directory, this doesn't work as expected. I can select my business service for the sender side, this works. However, for the receiver side I always have to specify a virtual receiver service and my receiver determination and interface determination are created with a virtual receiver service in it.
Is there any way to avoid the virtual receiver? Any help is appreciated!
Best regards,
Matthias

Hello Aamir,
you are right, I don't need virtual receivers for my scenaro and I also don't want to use them.
However, when modelling my scenario with an integration scenario in the design, I'm forced to do this and I would like to know whether there is any way to avoid this.
In order to be able to use a business service on the sender side, it seems I have to select the checkbox 'External party with B2B communication' in my integration scenario. When importing & configuring the scenario in the directory, I am then able to select by business service for the sender side. However, for the receiver side I have to specify a virtual receiver, otherwise I cannot finish the config wizard.
Any more ideas?
Best regards,
Matthias

XML Standard for B2B Integration

Hi B2B Gurus-
One of our client is looking at implementing a B2B solution using Oracle B2B to send and receive business documents with its Trading Partners (Suppliers and Banks).
The typical transactions as of now would be:
1. Purchase Order Outbound to Trading Partners
2. Advances Shipment Notice and Invoice Inbound from Trading Partners
3. Payment Files Outbound to the banks
The client will not be using EDI or Rosettanet standards. They are looking for XML standards ONLY.
I understand that Oracle B2B supports cXML, xCBL, ebXML, OAGIS etc
Can anybody please suggest which XML standard is the best for the above mentioned B2B transactions.
Please note that the back-end ERP system in our case is Oracle E-Business Suite R12.
Thanks in advance.
Regards,
Dibya

Hello Dibya,
RoesttaNet is a XML based standard but if I am right then your client does not want to use it.
Deciding a document protocol in B2B communication is mutual agreement based process between the trading partners, so I think your client should first check with it's TP's that which document protocol they would prefer.
Still if I have to give personal opinion, then I would go for ebMS because it has support for SOAP standard using which you may even connect with web-services of your TP (if they do not have a B2B product). Moreover, I can define my own message structure in ebMS (obviously with my TP's ack) and have CPP/CPA import functionality. There is also a PING-PONG message facility in ebMS to test connectivity between TP's. Apart from this there is also ActionName based agreement identification support for ebMS.
I would suggest you to ask your client to discuss it with their TP's and then take a decision.

Anuj

B2B Scenarios?? Urgent

Hi XI experts..
Anybody explain about Busines 2 business scenarios..
what are necessary steps i should follow to develop B2B Scenarios. Compare to A2A.
Share to me Some Real Time Example's..
Thanks,
RAJU

Hi Rajshekar,
B2B scenarios come in to picture when communication is between two Organizations or parties.
A2A - application 2 application:
this is a integration like let's say, you have 2 systems in your company: ERP & accounting system. And you want to send data from ERP to acconting system. This happens inside your company, so it is sol called A2A.
B2B - business 2 business
Let's say, there are 2 companies, and they have a different systems, which need to be integrated. For Ex: your client is using SAP R/3 and their customer is having some other technology. they want to integrate each Appications. this is B2B.
"B2B" is contemporary shorthand for a longtime sales practice called business-to-business. B2B transactions primarily target companies and other wholesale buyers, while transactions targeting individuals are called B2C, or business-to-customer. Many organizations have both B2B and B2C components, but it's not unusual for a company to specialize in B2B services or sales. In fact, the vast majority of products and services sold are considered to be B2B in nature.
One major reason for the popularity of B2B sales and services is sheer volume. An individual customer may visit a clothing manufacturer's website catalog and order two pairs of shoes or a sweater. The buyer for a national chain of clothing stores, however, may order 5,000 pairs of shoes and 2,000 sweaters. Without a B2B component, the manufacturer would have lost out on a very lucrative sale. This is why many companies provide B2B options alongside the B2C offerings at their websites and other outlets.
B2B sales are also generated by providing a specialized product line or service not available to the general public. This form of B2B transaction is very common in the manufacturing world. A company which produces shaving cream in cans, for example, may need a specific plastic nozzle. Several plastic injection molding companies would send sales representatives to pitch their particular designs. These nozzles would be useless for individual customers, but a manufacturer may order thousands of them.
With the growth in electronic communications, B2B has taken on even more importance. Instead of simply focusing on business-to-business sales, modern corporations are conducting other financial transactions online. B2B communications are now being used to promote investment, trade stocks and form financial alliances. Because the price of these transactions is far beyond the reach of most individuals, there is no equivalent business-to-customer option available. Some B2B transactions handled electronically can literally run into the billions of dollars.

What is A2A and B2B?

Hi Experts,
Please explain what is A2A and B2B senario?
Regards,
RajeshKumar

HI
A2A & B2B:
A2A is application to application. When two applications in a company communicates with each other we call it an A2A scenario and if its across Companies we call it B2B or buisness to buisness.
Consider an Car Manufacturing Company, it may use XI for integrating its ERP system with say an HR system and so on. As both systems are in the same landscape, it becomes an A2A.
Likewise, the Company might have transactions with say a Glass Manufacturing Unit or organization . When XI is used to Integrate these systems, it becomes a B2B as you use it to integrate 2 different Businesses in different landscapes.
B2B scenarios come in to picture when communication is between two Organizations or parties.
A2A - application 2 application:
this is a integration like let's say, you have 2 systems in your company: ERP & accounting system. And you want to send data from ERP to acconting system. This happens inside your company, so it is sol called A2A.

Today's business world is infinitely more complex than it was a long time ago.
Modern companies have a large number of applications that take care of
running the business. Such diverse applications weren't a problem initially
because they were meant to provide stand-alone, independent, and
automated functions. The result of this diversity was a collection of stovepipe
applications rather than a unified network of linked systems. But now, the
companies are realizing the utmost need to integrate these independent data
silos to leverage the information stored in them across the various vertical
and horizontal domains as well as surmount the ever-increasing costs of
building new applications.
And this is where an A2A Integration solution comes into the picture.
1>A2A Integration
A2A Integration is a collection of processes, software and hardware tools,
methodologies, and technologies. When implemented together, they have the
aim of consolidating, connecting, and organizing all the businesses computer
applications, data, and business processes (both legacy and new) into a
seamlessly interfaced framework of system components that allow real-time
exchange, management, and easy reformulation of the company's missioncritical
information and knowledge.
2> B2B Integration
B2B Integration is fundamentally about coordinating information among
businesses and their information systems.
In today's world with companies operating in a global business environment,
B2B Integration is a pre-requisite for them to remain competitive. They need
to come out of their shell and interact with their suppliers, partners, and
customers distributed throughout the world. B2B Integration enables a
company to focus on its core competencies and offload other services to
partners to gain efficiency and reduce cost.
A2A:
If you do the Integration for Business Process in the same LAND SCAPE then it is called A2A .
B2B:
If you do the Intergration for the BP out side the Customer LAND SCAPE then it is called a B2B

Hi friends,What is A2A andB2B communication

1)What is A2A andB2B communication

Hi,
A2A or Application To Application communication is the communication between hetrogenous /homogenous application with an organisation network or firewall.We use Service without party in case of A2A communication.In case of A2A communication, we don't get the option for Encryption Key,Decription key, etc while creating Sender and Receiver Agreement as the communication is within an organisation's firewall.
B2B or Business To Business communication is between two separate business entities like an organisation wants to communicate with its business partners having separate landscape.We use Party in case of B2B communication.
In case of B2B communication , we have the option for Encryption Key,Decription key,etc while creating Sender and Receiver Agreement.

Proxy server usage

One of my customers is trying to use the OHS as a proxy server .
This is the use case:
B2B Channel has been setup to use SFTP with a Trading Partner.
They want to use a proxy-server on the DMZ for all communication and file transfers with the outside world,
and do not want to expose the internal SOA 11g/B2B server.
Is there a recommendation from Oracle B2B experts on how to achieve this?
Please let me know.
Regards,
Vidhya

I've implemented something similar in 10G B2B.
B2B SFTP transport to standard Apache 2.2 (not OHS).
B2B SFTP transport has proxy port and address specified, as well as target (user, private key, server name).
B2B SFTP transport uses a public/private key for authentication to target (no authentication to Apache proxy - Apache server uses ACL's for internal access).
Apache proxy uses a virtual host, listening on custom port (not 22).
This works well and the same Apache proxy is used for proxying AS2 and ebXML connections.
