I am not able to delete tasks which are duplicated , have EAC for one user(screen shot 1).
As per my understanding user created has Milestone then he updated as Deliverable and he tried to delete those as it was created by mistake But it is not succeed as it have the EAC.
Task start and end dates are 31/03/2015 but how EAC is appearing , user do not have any actuals and it is not came through normal month end process.
Can you please help me to understand how duplicate ids are created/accepted (task name, task id)
How the EAC is appearing .
How to remove EAC to delete tasks (if it is not possible from UI then how to delete from DB).
