Oracle Error Message

ORA-25316: Late in the current transaction to begin an Enqueue/Dequeue operation

Reason for the Error

Check if the Enqueue/Dequeue operation is performed via triggers on Materialized Views which isn’t supported.

Solution

Triggers on materialized views aren’t supported. Workarounds are on-demand materialized views or execution of trigger code within an autonomous txn.
