The user has noticed that the End Date on the Permit is Later than the Estimated End Date on the Works Phase
Go to TMA > Activities > Works to check the estimated end date then check the date in the Permit tab - It seems to be 1 day later.
There are 2 types of permits, Fixed and Sliding. Fixed means that the estimated start and end date cannot change, where as in a Sliding permit the start date can slide by 1 day.
If you look at the Works and check to see what the Estimated and Latest end date show, you will see that the Latest end date is the same as that in the Permit tab. This is so if the utility start 1 day Later as they are allowed as they are still working under a valid permit.
