Answer / krishna

Batch Data Communication Session
The first step in a BDC session is to identify the screens
of the transaction that the program will process. Next
step is to write a program to build the BDC table that will
be used to submit the data to SAP. The final step is to
submit the BDC table to the system in the batch mode or as
a single transaction by the CALL TRANSACTION command.
