hi
Session Method is one way of performing BDC. In this process, the data which is coming from an external file is processed and then put into a session. To process the session, we need to use SM35 transaction code. We can from there process it in foreground or background mode.
To do BDC for a transaction, we need to perform the recording from tcode SHDB and then create a program using the recording.
During the recording, we give test values which we normally give.
For example, in va01 if we give plant as a001 during creating transaction..the same value should be given during recording.
