Hi,

A2A: It means within the firewall i.e. within the organizations.

B2B: it mean outside the firewall i.e. dealing with third parties as well as within the organization too.

For more info go to this thread too.

Hi,

Should we need to create Party in ID for the Both Sender & the Receiver Applications ????

If My Scenario is Like IDOC to File

Regards

Babu

[nisarkhan_n]

it depends on which system either sender or recievr is a a party if botha re then you haev to create for both...usually it is one system which is outside corporate defined aprty...

Hi,

See here my client wants to send the IDOC to their Customer's Legacy system.

Then here I think we need to create Only one Party . Right ????

Regards

Babu

[nisarkhan_n]

yes ...the IDOC which you client wants to send is in the lanscape but the legacy system is in the customre place (outside corporate) then your customer legacy system acts as a party based communication here

Hi Babu

A-A > It involves direct and simple communication between two or more application i.e impact on one system directly affect the other end communication system.like you have to create purchase order in MM hosted on one application server which communicate with SD hosted on other application server. so it is one application to other

<b>no third party involved</b>

B-B > e.g if you have to create purchase order in MM hosted on one application server which communicate with SD hosted on other application server which in turn impact several other application hosted on several different customer's partner application server which may be SAP or non-SAP application, then it is business to business

Hi babu,

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.

Consider an Car Manufacturing Company XYZ, 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.

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

Now suppose the Company XYZ 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

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.

Hi,

If I Understood is correct that

If we want to Integrate sap r/3 system with peoplesoft system to send the data Using XI with in the XYZ Company Which is Located in ABC Location.Then

We Use A to A Integration . Is it Correct ????

If XYZ Company in ABC Location want to Exchange the data with their Customer PQR Located in US Location.Then

We Use B to B Integration. Is it Right ????

Q1 ) I Think mostly we use XI For B to B Scenario's Only. Why Because the Business will be like that naaa ?????

Please Correct me if Iam Wrong

Regards

Babu

[nisarkhan_n]

yes you are right...we might use any either A2A and B2B but mostly depends upon the busniess of the company which is implementing the XI.

Yes, within the same organization boundary.

Yes

It depends babu, completely on the business process. If the business process demands B2B then we have to...

[nisarkhan_n]

yes, in a single stament

In A2A(Inside our Corporate Boundary)

B2B(Outside our Corporate Boundary) so when you are speaking outside corporate you have to define that system a s a party based commmunication.

also

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.

let me explain it in simple word....

when u create scenarios in ID we r having 2 options

<b>1)with party

2)Service without party</b>

since in A2A scenario we r doing all integration within the same company/landscape we r using 2nd option i.e Service without party(as its within same party...)

but in B2B scenario we r doing integration between diffrent organization/landscapes... so...we have to specify the party also...when u create BS ..u have to tell ..which party this BS belongs to...

i gues u r lil bit clr now!!!

Hi,

Is there is Any Chance to have the XYZ Company & Their Customer PQR in the Same LANDSCAPE.

So that they can go for A to A Integration

Regards

Babu

[Former Member]

hi,

Not really.

The XYZ Company may expose certain services for consumption by PQR and vice versa. But there are very minute chances that both companies are in same LANDSCAPE

regards

Ramesh P

[nisarkhan_n]

chancess are less in same landscape also it depends on the type of system invaloved in communication.....

suppose you want to communicate with your customer ex Database ,File syetem. Http...and so on

you have to acess this remotley (daatabse you cannot dfirectly) over HTTP i think you can but not for toher types

some thing you cannot caess remotly but not in the same landscape.
