Follow these best practices for managing Preventative Maintenance Plans.
Deactivate plans when you are finished using them. For example, a seasonal plan. The plans can be Activated at any time.
Delete plans only when a mistake is made while creating a plan that cannot be edited. Any scheduled tasks created from a plan remain and all projected tasks are removed.
Once a plan is deleted, that name cannot be used again. For example, if you delete a plan named, Park Maintenance and later try to create a plan with the same name, the system does not allow it.
