Raja,

XI is a middleware.

EDI is a industry standard messaging formats that most of the middlewares support

BAPI is a SAP propreiatry way of integrating SAP with other applications.

XI - You can do message mappings.

The sender system need not bother about the target format.

Middlewares are more strategic in a organization, usually all the integrations in a org. happen through a middleware.

Raja,

You cannot compare EDI / BAPI to XI, read my first post more carefully. XI is a middleware and EDI is standard and BAPI is a way integrating with SAP.

XI can do the integration using EDI formats, where as EDI messaging formats cannot be understood by SAP Directly. So, XI transforms EDI message format to a IDOC / BAPI format and sends that to SAP.

You need to understand the purpose of middelware first. Search on the web if you can find any info on the baiscs of middleware.

Regards,

Ravi

Raja,

Yes, XI transforms the EDI message format to a IDOC / ALE format, but you (XI Consultant) will have make that message mapping either graphically/java/ABAP/ XSLT so that the mapping happens correctnly. Now, the middleware also check for mandatory data and can also do the value mapping, calculations as the data in one system might be represented in a different format / value.

Ravi

Hi,

XI :- Is the middleware tech.

It stands between SAP and outside world.

It Handles Data in XML format;

XI is directly connected to SAP.

Since XML is unversal format of data ; it can stand between any Non SAP and SAP system.
