A2A - Application to Application

Where you want to exchange some information into one Landscape That is we can say one MNC Company where it has location all round the world.

B2B - Business to Business

Where the excnage of information between two different Parties or companies or land scape, Where Firewall security will come into picture.

Hi Khanna

Developers will play a key role during

3. Realization

4. Final Preparation

5. Go-Live and Support this three stages mainly.

During 1. Project Preparation 2. Business Blueprint Architects and leads will prepare the technical documentation for all the interfaces depending upon the requirements of the client.

In realizaiton he will develop all the interfaces. Once you develop you will move al lthe objects to QA and then in prod.

If there are any changes you will make in dev and move once again in QA and prod in Final preparation.

During Go live and support you will monitor all theinterfaces. If they have any issues you will resolve them.

Modules in the sense, it will be depends on the client requirements. Here You will work on the interfaces like file, idoc, http, soap, jdbc etc with udfs, fcc and bpm

Hi Vasu,

Here Actually my Doubt is If We r Doing a Project to 'XXX' Client.

Then that Client Have Vendors to Supply the Material .Here there Should be a Communication Between those Two People.

Q1) Here Vendor And the Client have the Same Landscapes Or Different Landscapes .

If Different Means It should be the B2B Otherwise A2A Only Is it Right ???

Q2) Similarly for 'XXX' Client have Customers to sell the Product. Here Also they have the Same Landscapes Or Different Landscapes ?????

Please Clear my Doubt....

Hi Rajesh

Yes, there should be a communication between sap and non sap system.

A1. If both are in the same landscape then it is a2a otherwise it is b2b

A2. For this it is depend upon the client requirement.

Hi Khanna

Here I will give you one example. It is File to IDOC Scenario. In the Sender side, there will be an xml file which is developed from the software using .net, let us say the file contains the PO Details. Using that file I will generate the IDOC and post the PO in R3.

If both the .net system and the R3 server are in the same network and same landscape then it will be an A2A application other wise it will be an B2B application.

<i>Generally Vendor and the Client Are in the Same Landscape or in the Different Landscapes ?????</i>

For this it is depend on the situation, some times vendor will be in the same landscape and some times in different landscape.

Hope it will clear your doubt..

Cheers..

Ans

[prateek]

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.

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.

For B2B integration in SAP Xi refer the following links .

Hi Prateek,

U Explained the Scenario in a good Manner .

Then i have Another Question for you ,

Now a Days Mostly Which Integrations Are Going on.........?????

Please Clear me

Regards

Khanna

<i>Now a Days Mostly Which Integrations Are Going on.........????? Is it is A2A Or B2B ?????</i>

100 % depends upon what ur organization is looking for..

Suppose u have a big organization which is moving towards SAP implementation. They would like to have their implementations according to the SAP recommendation. Now if various systems are talking in terms of XI, then u have to use A2A.

Whenever organizations plans to have their communication with external partners in terms of XI, then B2B is used and cant b avoided.

What is the Percentage usage of A2A ??? And B2B ???</i>

Noone can tell u that exactly :)..

Ok Prateek,

If We r Doing a Project to one Client Means then that Client Should have the Interaction with their Business Partners<b>(Ex: Vendors And Customers)</b> it would be a <b>B2B</b> And there Should be a Data Interchange between them.

Then in the Real time We should go for the B2B Only And in Rare Cases A2A .Is it Right ???

Please Help me

Regards

Khanna

[prateek]

<i>Client Should have the Interaction with their Business Partners(Ex: Vendors And Customers) it would be a B2B</i>

In this case Yes. It could be.

<i>Then in the Real time We should go for the B2B Only And in Rare Cases A2A .Is it Right ???</i>

Now this is the scenari that u had taken. For this B2B is used. Thats correct.

SAP is generally implemented by large scale industries. These indutries r so large that their internal working among the organization is also very complex. The integration in this case would be A2A.

The point is both B2B and A2A r widely used and will be used in future.
