With this feature, you will be able to edit the next due date for assets on Maintenance plans instead of the maintenance plan locking the date. This can be done on the service order for the asset in the Order Detail View.
First, select the work order for the asset you're trying to edit. Get to the work order through the "SERVICE" module, select the work order, and click Order Detail View.
Under the "Labels & Reports" section on the left hand side, you'll be able to click the "Reset Service Date / Task" check mark to override any maintenance plan date, and set the "Next Service Date"
