Hi all,

What is the difference between XI and BAPI, as I know one is middleware and other is interface, because using Business connector we can send the BAPI call as an XML to internet and viceversa can be done. Then why we are using XI for SAP to Internet (like EP) or viceversa. Please clarify in this regard.

and Is SAP System mandatory for XI? (for connecting two nonsap systems)

Regards,

V Kumar

Hi Kumar,

You have to take into account that XI/PI is the current version of Business Conector (more or less).

XI is the broker, the EAI. BAPI is one of the way to send/receive data to other systems. You can use

BAPIs inside XI.

and Is SAP System mandatory for XI? (for connecting two nonsap systems)

What is a XI system? It is a SAP system With a Netweaver platform. Moreover an Adapter Engine and a Business Process Engine.

Whatever you want to connect you will need a system with these features, although the systems which are connected are

non-SAP systems.

Use RFC for Syncronous communication, when u want some response back.

for example if u want Employee detail from R/3 system, you will send employee id. RFC take this as a input and send back detail Employee information.

Look these scenario to use of RFC

/people/sap.user72/blog/2004/11/23/unification-connector-framework-relation-resolving-drag-relate-object-based-navigation-and-other-strange-words-150-the-real-story) for my scnenario is XML to RFC TO XML, and my XML structure is next:

<?xml version="1.0" encoding="ISO-8859-1"?>

<Body>

<date>00:00:00</date>

<P_KOKRS>CSTK</P_KOKRS>

Hi

1 BAPI is used when we need to Exchange Data only from the R/3 system.

2 XI is Middleware that provide open format(XML) to communicate with any Application Based on Tecnology like Java, .Net. It works like Hub that provide end to end integration b/w Application or cross component

3 XI Can be used b/w 2 non-SAP Application,no need to install R/3.

XI replaces Business connector and do the same job BC use to do. Using XI also you can send BAPI data as XML to internet and vice versa. In XI terms this is called (RFC -> HTTP) scenario. XI is also a system of SAP. XI sit at process integration layer. ALL sap and non sap systems can be integration using SAP XI.

and Is SAP System mandatory for XI? (for connecting two nonsap systems)

SAP system in the sense R/3, SCM, ERP etc are not required. SAP XI have ABAP and Java stacks and can be installed independently without any other SAP systems in landscape but Basis is still required.

Thanks

Hi

>why we are using XI for SAP to Internet

SAP XI / PI is a Middleware tool, Where Transformation,Montoring, Error Handling, Alert etc can be handled

@ Agasthuri Doss & Gaurav

May I know the scenario for which we will go for XI and BAPI. Say for ex, if I need to transfer the data

from Internet to SAP, then which is the best way?

and When we will go for BAPI Interface.

V Kumar
