To disable a planned maintenance you need to :
- click on "Equipment" on the banner on the left of the screen
- click on the equipment on which you want to deactivate maintenance
- select the maintenance to be deactivated
- click on "Edit" on the right side of the screen
- click on "Disable"
You can easily deactivate a maintenance, however it is not possible to deactivate the first maintenance done in order to avoid possible falsification of maintenance history.
