Hi,

When you are dealing with in your Organization levele or Network level means it is A2A Scenario

B2B Means the communication 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

Hey

Contrary to the popular belief,A2A and B2B has nothing to do with the companies landscape at all.

take for example company A which sends orders over web(HTTP or SOAP) to its vendors,now both these companies are different,they have different landscape,but still its A2A.

Similarly within the same company,you can have 2 departments,one receiving orders(Sales) and the second sending invoices(Financial),then are interacting via some industry standard adapters,here even though they are within the same landscape(company)they can be considered as a B2B.

as far as party is concerned,you can use that for A2A as well,wont make any difference.

I don't differentiate between them,only thing which i make sure is the kind of adapter i am using,that affects the configuration hence might require some extra/less effort.

Thanx

Aamir

Pl:Search SDN before your questions,this topic has been discussed several times before as well.

HI

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 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.

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

Hi,

A2A means application to application,it refers to scenarios which u do within ur landscape.suppose u have a R/3 and a File server and ur doing IDOC to File,then it will be a A2A scenario.

B2B means business to business,it refers to scenarios between two separate business(different landscape),suppose u have company A which wants to talk to company B withour exposing their internal landscape,now in this case it will be a B2B scenario.

party comes into play for B2B scenarios,its actually a name given to your business by organisations like DUNS,NAFTA etc. and uniquely identifies ur business.u can think of party as a postal address for ur organisation.if someone from outside has to send you something then he needs ur postal address(party) but if u want to interfact within ur house ,u dont need any postal address,hence no party name.

Hi,

When we are dealing a scenario which is A2A we will use Service with out paty

When we are dealing a scenario which is B2B we will use Serivce with party.

what is the difference between these two

Let's discuss what is A2A and B2B:

A2A: Application to Application,Here the Integration is done with in the same landscape with in the same company.

B2B: Business to Business,Here the integration is done one business partner to another business partner.

Business partner A is Landscape is different and Business Partner B landscape is different..In such a situation you want to communication for Business Partner A to Business Partner B ..is called Business 2 Business.
