Doubts on JDBC & FIle

Question

1.  IN A DATABASE -> IDOC scenario,
if a reverse scenario, when ever an idoc is triggered it gets updated automatically into DB because of the ALE settings we do. But when DB-> r/3, how does this automation takes place. i mean.. when ever a new records come into DB, does idocs get created automatically?
2. in a file -> idoc or DB scenario,
my file data is holding both header data and item data. how can we identify which row is header data and which is item data?
3. i am doing and idoc to DB scenario.
in sxmb_moni, i am getting strange message from trace of XML message "Async barrier reached. Bye-bye !".
i have checkd my complete config and its right.
i also tested my mapping with the payload and its working fine.
Thanks

hi kiran!!
1. If you want to update R/3 upon Manual Database record change, you have to configure it in the Database side itself. You can engage a trigger for the particular event(INSERT/UPDATE) to reflect the change in the R/3.
2. Specify key filed values  for header, item and for footer
   i.e. in the recordset structure: header,<occ>, item,<occ>,footer,<occ> //occurrence.
in the CC Table:
header.keyFieldValue 'H'
and put values for item and footer accordingly.
3. check in the adapter monitoring (RWB) if there is any violation in database
