Hi Shansiva,

A BAPI can interact and integrate with the software components of other vendors.

A BAPI is a Function Module in SAP that can be integrated with the legacy system

to access the SAP business objects

or it can be called inside the SAP itself depending the business requirement.

Using a BAPI, we can fetch data from SAP or create/update the SAP master/transaction data.

There are BAPIs available for each transactions that are performed in SAP.

<b>Answer for Qus1</b>

For example, there is a BAPI available to Create the Customer Master in SAP.

That BAPI can be integrated with the legacy system using Remote Function Call (RFC)

to create a Customer Master in SAP.

By this way it interacts with a legacy system.

<b>Answer for Qus2</b>

A BAPI is also used in the interface of 2 SAP systems.

For example, the data from a SAP system1 need to be updated in another SAP system2.

For that purpose, call the BAPI of the SAP system1 from the SAP system2 as a Remote Function Call (RFC).

The connection between the 2 systems are maintained using a RFC destination & the data are transferred between the 2 systems using IDocs.
