Once asked above questions to development team in meanwhile we need to start basic sanity check in our environment. 1 Verify the status of the concurrent program select REQUEST_ID,phase_code,status_code,ORACLE_SESSION_ID from apps.fnd_concurrent_requests where request_id=’1234567’; 2 Find which concurrent manger ran a specific concurrent request select b.USER_CONCURR
