BDC is Batch Data Communication where data is transferred from legacy system to SAP system. Different methods of BDC are

1. Call Transaction Method.

2. Session Method

3. Direct Input method.

In all the above methods you have to prepare a flat file containing the data in the required format to be uploaded to the SAP system. You need to call the function ' UPLOAD' to do this. Then the contents of the flat file have to copied to your internal table and then u need to call the transaction through which you want to update the database. You internal table should also have the information relating to the structure BDCDATA which is having the details like the module pool program name, screen no. The basic concept of updating the database is same in all the 3 methods but only the method differs.

In session method after the data transfer program is coded, in order to process that particular session you have to go to TC: SM 35 to process the session.

Direct input method have some standard programs that have to executed.....

Reward points if helpful.
