CLOSE DATASET FILE.
You require the function modules for opening and closing sessions.
To insert the data in the session, you set up the BDC table in a subroutine and call the function module
BDC_INSERT.
You set up the BDC table and call the subroutine in a loop for reading in the data with READ
DATASET.
The called subroutine is similar to the subroutine in the first program example.
