Data picked up from JDBC table, but no message appearred in Monitoring

Hi Experts

I m taking data from a JDBC table where the a field flag=0 and then updating that flag from 0 to 1.Once i run the scenario the flag got updated to 1, but i m unable to see any message in my XI Monitoring. Sometimes it appears , but most of the times i didnt get the message.

What may b the reason. Its causing problem, coz the table shows that data is processed(Flag updated), but no corresponding action is actually taking place.I m wondering, if the data is being picked up, where its going? Moni shd show the message picked.

Any clue??

Regards
