SQLException in query for transaction Error Message ORA00942 table or view does not exist

My server where my previous integration was pointing to was changed. Althu i configured my adapters to this new server and schema but while running the ATC in debugger mode I faced the following error.

10:04:42 AM ; Error Code: 942; SQLState: 42000
