Regarding A2A & B2B Scenario development in SAP PI /XI?

Hello Experts,
Kindly clarify my doubt regarding A2A & B2B Scenario's development in SAP PI / XI.
I mean when to use & which adapter user in which scenario & specifically what difference does it make when we use one adapter in one scenario meant for another one. Will it work?
The Question may be quite Naive to all of you but still want to clear some thing from my head.
Best Regards
Priyesh Shah

Hi Inaki Vila,
Thanks for Reply, i did searched SDN before raising this question. i stumble upon this difference between A2A and B2B scenarios.but the question still remain in my head what adapters should i use for B2B scenario is it necessary that i should use EDIFACT for B2B & not for A2A. Here in my company we are handling a client which has several legacy system in landscape which are integrated to SAP ERP with SAP PI here they mostly used File Adapters, what happens if i use File Adapters for B2B scenario.

A2A and B2B Scenarios

Hello Friends,
Can any one explain what is A2A and B2B Scenarios and please explain what is asynchronous and synchronous communication.
Thnks&Rgds,
Dinesh

Hi Dinesh,
1. A2A integration involves configuring your system landscape, designing your integration scenarios, configuration of the scenarios, handling messages. In which you communicate at application level.
2. B2B Integration
Its something in which two business are integrated like: we develop scenario like legacy system to MDM using XI.
Now two businesses are communicating. See the link:
http://resources.ecommercetimes.com/search/keyword/ecommercetimes/Definition%20B2B/Definition%20B2B
3. Asynchronous communication:
Means you will send the data but no response will come from the receving end called Asynchronous communication. You will just send, disadv: your data may lost.
4. Synchronous:
Every time sender will send the data, receiver will give a response say acknowledgement to the sender that data received.
Adv: if data is not going to receiver it can be delivered again.

What is a B2B scenario definition from XI perspective ?

Hi All,
what is a b2b scenario in xi ? suppose, data flows from wholesale dealer database to companies r/3 system, will it be a b2b scenario ?

Hi,
Here goes a simple explanation :
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.
B2B scenarios come in to picture when communication is between two Organizations or parties.
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
If you do the Intergration for the BP out side the Customer LAND SCAPE then it is called a B2B
The scenarion you are talking about falls under B2B , if the wholesale dealer database and r/3 system doesnot fall under same company (enterprise).
Hope this is helpful.

Divya

Can anyone explain A2A & B2B AND BPM & ccBPM with an example..

Hi All..
Can anyone explain me A2A & B2B
and BPM & ccBPM with an example....
NOTE: i dont need definitions but examples..
i am bit confused with this stuff....
Thanks in advance....
Cheers,
raghavesh

Hi ,
A2A & B2B
This thread explains you the difference between A2A and B2B.
Re: A2A Vs B2B
BPM & ccBPM both are same....
BPM is used to implement work-flow spanning across multiple application system against embedding the parts of work-flow in application system. Apart from this it also help achive other scenarios like, bridging synch and asynch systems, alert mechanism, multi mapping etc. Check the BPM overview document in SDN download section.
Check out the use cases discussed at http://help.sap.com/saphelp_nw04s/helpdata/en/de/766840bf0cbf49e10000000a1550b0/content.htm
BPM is mainly used in senarios where extra functionalities are to be done with the source message which cannot be done using the normal mapping and user-defined functions, like
-->Collecting of messages till a certain count or for a specific criteria.
-->Merging messages
-->Spliting messages
-->Processing of error files and sending to specific location and sending alerts.
-->Parallel processing of two criterias at the same time can also be done using BPM.

B2B Scenario (????) Help

Hi All
We have a req which was given very short. The invocice details are to be validated in a screen and are to be posted into R3 (Client's customer). I hope this makes a B2B scenario. Need your suggestion in how to goahead with this req. Initiaaly i thought of having some websrveice consumed and using either HTML client or EP the user can vlaidate the invoice data and post to R3 of the clients custmer. Kindly adivce on this and also link me to some useful docs adresing a similar scenario.
thkx
Prabhu

Hi Prabhu,
I am sorry, I don't have any standard doc for your requirement because as stated earlier there is no difference in A2A and B2B scenario.
>> Validate invoice data.
- Use either ABAP report or webpage to display UI for user.
>> backend for invoice data
- If using abap report then ztable else any database table.
>> Send invoice data to customer.
- If you have any RFC destination for customer's client R/3 then you can import Idoc/RFC directly (I am assuming you are going to post Idoc in R/3).
--- Create JDBC-XI-Idoc (RFC) if you are using web GUI
--- Create RFC-XI-Idoc (RFC) if you are using ABAP report with ztable.
-If you don't have any direct connection with your customer's client then it is now tricky. Proxy/firewall comes into play.
--- Agree on common stepping stone which is accessible via both party.
--- create JDBC-XI-File (or HTTP) scneario.
--- Post file into customers R/3 either using RSEINB00 or any other ALE method.
--- You can also use AS2/AS3 adapter from Seeburger for communication.

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.

How to configure B2B scenarios ?
And what is difference between A2A and B2B ?
Thanks in Advance

http://en.wikipedia.org/wiki/Business-to-business
Business-to-business (B2B) describes commerce transactions between businesses, such as between a manufacturer and a wholesaler, or between a wholesaler and a retailer. So are B2C & B2G..
One of the partners involved in your integration is external to your landscape.. So B2B scenario's would involve security (HTTPs, FTPs by Encyptions, security certifiacates) or documents being exchanged (EDI- EDIFACT, ANSI-X12, or other industry standards like RNIF, CIDX...) that don't generally happen in an A2A landsacpe or integration between inter-company systems.
It has not much to do with Business systems or Business services per se.... Its more to whom you are interacting & how you are interacting...
Search for the blogs of Kevin Benedict & B2B on SDN, you would get very good idea of B2B scenarios, challanges

For sending file in B2B scenario

Hello Friends,
I need to pass a file to my client's business partner...
I think its a B2B scenario...
So how to transfer a file my client to his business parntner.
Please suggest which adpter to use at receiver side and how to handle the configuration..
It should be secure and reliable

hi,
you have to use FILE ADAPTER but you need to use PARTY when you are using BPM
check this blogs for reference
BPM means Business process management
To deal with Multiple sender and receivers based on the conditions we could use BPM. Its one of the feature of BPM, but its not mandatory to go for BPM for each n every case. Its depends upon scnenario.
BPM steps are divided into two types:
1)message steps
2)flow steps
message steps are :
a)send step
b)receive step
c)receiver determination step
d)tranformation step
flow steps are:
a)control step
b)container operation
c)block step
d)wait step
e)fork step
f)switch step
g)undefined step
h)loop step

Namespace issue in a B2B scenario

Hi all,
I have an iDoc to iDoc B2B scenario (R/3<->XI<->XI<->R/3),
My partner has defined an iDoc extention and sent me the xsd.
Now I have a problem in defining the interface because I don't have the same iDoc definition(different R/3 version) so I cannot import it into the IR, and I cannot define the message type and message interface as an external definition because the MI is in the iDoc reserved namespace.
How can I solve this conflict ?
Thanks,
Elad.

Hi Elad (or Ofir?),
my idea was to change temporary connection data for import from SAP system of SWKV. The question is, if you dont have connection to that system, how do you want to connect with XI and how do you want to test?
2. idea was: instead of imported idoc you just create a dummy interface in repository. The interfaces itselfes (and so the imported idocs) will not be validated by integration engine. Only if you use message mapping you really NEED a correct XSD schema.
So something like R/3 idoc -> own interface -> any mapping except message mapping -> loaded idoc interface -> other R/3

Udo

JMS in a B2B scenario

We have a scenario where external partners will transmit requests to our application, which will reply back with some results. Some of the other requirements for our application are: support for concurrency, scalability, high avail, etc.
We feel that using EJBs to model our application will help us because the EJB container/appl server will handle security, transactions, etc. That's good - but, our problem is how would the external client applications communicate with us ?
One solution would be: we expose the remote interfaces of our EJBs and the external applications code to that interface. But, this may mean that any time we change our interfaces, the external applications also need to be changed. This may be a pain ;-)
But, what if the external applications send requests encapsulated in a mutually-agreed message format and receive responses via messages ? Yes, I am thinking about JMS. Our external applications can send messages to queues in our JMS provider. Our application picks up requests from a "request" queue and inserts results into a "results" queue. The external applications will obtain these results from this queue.
I was going to spend more time researching on this, when I came across the JMS FAQ, which says that JMS is to be used only within an enterprise, while ebXML messaging is recommended for a B2B scenario.
Before I discard my current line of thinking, I would like to get some input/advice/suggestions as to whether JMS will work in our scenario. If not, what kind of an architecture would help us ?
Thanks a lot !

Hi,
I don't think you need discard your current thinking. Yes some JMS implementations are best placed in the enterprise however some are designed specifically for external connectivity and building business partner networks. Our own product ( Nirvana ) is one that has been designed for externally facing middleware connectivity. Our messaging functionality resides above a pluggable transport layer and supports sockets, SSL enabled sockets, HTTP and HTTPS transports. The whole proxy and firewall traversal problem is handled correctly. There is no requirement for a web server ( although we have produced an Apache module for reverse proxying ) running a suite of servlets.
We are currently packaging a new release that provides a new JMS implementation as well as a P2P framework. All of which runs over our pluggable transport drivers. The P2P framework supports the concept of BOP's ( Business Object Proxies ) , this functionality allows you to create services that are directly accessible from pretty much anywhere.
We would be more than happy to provide you with an early access distribution prior to us updating our web site. Please feel free to contact us.
