A2A or B2B

Hi All,
I have a scenario, our client has SAP R/3 and they want to integrate SAP R/3 with their Vendor for their Transportation.
Vendor has sterling commerce system, So we can make the scenario's as File to Idoc & vice versa.
Now my Question is, Is this going to be A2A scenario or B2B??
I believe this will be B2B. Please correct me
Regards

Hi,
Well , Technically speaking there would be not much difference. Its only a Business/Functional terminology.
Designwise , no much difference. Both would be same.
COnfigwise, we, as developers come to know, if we integrating with a system inside the organisation or Outside the organisation.
Example,
A webservice interface to a Non-sap tool within organisation(A2A).
we will be using the local URL in SOAP adapter.
A webservice interface to a Non-sap tool with a partner organisation of our client(B2B).
we will be using Partner organisation URL in SOAP adapter.
OR
sending the file output to a local tool(A2A).
FTP' ing the file to a partner(B2B).

Regarding A2A And B2B Integrations in SAP XI

Hi Experts,
I want to Know the Difference Between the A2A And B2B Integrations in XI.
Any one Can Please Explain me In General Words Using One Real Time Scenario.
Helpful ANS Will be Rewarded.
Regards
Khanna

Hi Rajesh ,
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.

Regarding A2A and B2B applications

hai can any one give the real time example on A2A and B2B scenarios its a frquently asked question in interviews

Hi Chandrakanth,
A2A scenario means - you are sending the data across different applications using XI
Ex : File to IDoc , File to JDBC, HTTP to JDBC ,...etc...
General scenarios with in a company .
B2B Scenarios means : A company wants to integrate their systems with their business partners ( ex vendor,supplier,customer) , implicitly it means that they have to cross their fire wall for this purpose ...In B2B scenarios we need to create Party objects.
The basic difference is in B2B you have to use Party objects and Industry standards like CIDX,RNIF adapters at configuration time . Rest the scenario is similar to A2A ...there also you will be integrating different applications but you will have to cross the fire wall.
PS : Can you put all your questions/doubts in one thread rather then making n different threads for each and every doubt/Question.

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.

A2A Vs B2B

What are all the Major differences between A2A and B2B
In A2A(Inside our Corporate Boundary) and B2B(Outside our Corporate Boundary) we need to have the following for sure
1) Sender and Receiver Adapter
2) Message Mapping (if the source and Target structures are different).
What other differences we can list? In XI whats the different process that we need to take into consideration when we do B2B (File1 to File2) when compared to A2A (File1 to File2) ?
Thanks

HI Mohan,

In A2A(Inside our Corporate Boundary) and B2B(Outside our Corporate Boundary) we need to have the following for sure
1) Sender and Receiver Adapter
2) Message Mapping (if the source and Target structures are different).
Yes correct, but you need to identify other system landscapes . For this you need to have Party configured.
Some quick Tips-
-Check the Firewalls/Security
-Should have different system Landscapes in place and need to know the communication protocols/message formats between different landscapes to make the good design
-Knowledge of networks/firewalls is additional while designing the solution

In simple terms:
A2A:
Integration of internal company processes by seamlessly connecting SAP and non-SAP applications.
B2B:
Integration Outside the organisation.
For B2B integration u need to use the third party adapters,for example seeburger As2,X400,OFTPS etc.

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.
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.
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

If you do the Integration for Business Process in the same LAND SCAPE then it is called A2A .

If you do the Intergration for the BP out side the Customer LAND SCAPE then it is called a B2B

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.

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.

Appriciate your Inputs..

Narayana.

Hi Narayana,
IF you want to exchange message with RosettaNet compliant system then we use RNIF adapter in B2B environment .
RNIF adapter supports PIP message format as per me experience,

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.

Gourav
