Answer / rasapppan krishnamoorthy

The purpose of the Batch Data Communication is to transfer
data. The BDC can transfer data from one SAP System to
another SAP System or can transfer data from non-SAP System
to SAP System too. To transfer data BDC uses normal
transaction codes. Two methods are provided to BDC to do
this work. one is classical method or session and second
one is by using ABAP statement CALL STATEMENT USING. in
this method there is no need to create session.

Transfering data
................

Firstly, you will analyze the structure of the existing
data. Subsequently, your job is to specify the conversions,
which are essential to fill the SAP data structures.

Secondly, you have to generate the SAP data structure. In
case the program is written in ABAP, you will require only
the required tables in the concerned program with the help
of TABLES statement.

Thirdly, you will have to initialize the SAP data structure.

Fourthly, fill the structure with data, performing any
conversions and error checking that are required.

Finally, you will write the sequential file. In the SAP
system this sequential file is typically required for
making the data available to the batch input program.
