>>i found S in sxmb_moni. whats the problem?
If you see S status in sxmb_moni, then see that you have any errors in sxmb_moni in any of the pipleline steps. If no errors and everything successful in PI and still status does not impact in table, then talk to DBA.
a) Are you updating in different schema of the db table?
b) Check with dba like autocommit not enabled on the db side?
Also you could configure
logSQLStatement = true in the Advanced tab of the jdbc receiver just to log your query. This might help.
You might also work with dba and come to the decision about setting transaction level in the adapter. Assume that some other application /system modify the same table too at the same time or different time.. If that's the case, you need to set transaction serializable highest isolation level.
