The system opens a second roll area for the called transaction. There, it processes the individual screens
and copies the data from the table. When the transaction has finished, the second roll area is released
and the processing continues in the first roll area.
Notes:
In contrast to batch input, there is no error logging. Whether the called transaction is processed depends
on the authorizations of the calling user. The BDC table can only accept data for a single transaction.
This means that before the next transaction call, you must perform a REFRESH on the BDC table and
refill it with data.
