Enterprise Asset Management Work Orders are created against assets. They can be defined manually, or generated automatically based on a scheduled Activity. If you attach a manually created Work Order to an Activity (normally the role of a Planner), the work Order inherits the Activity’s attributes, such as the Asset BOM, Asset Route (operations), attachments, quality plans, cost information, and scheduling rules.

The operations within a Work Order do not need to be complete in order to complete a Work Order. However, the date you complete a Work Order needs to be greater than (later) or equal to the end date of the operation that has the latest end
date. Likewise, the date you start a Work Order needs to be earlier than or equal to the start date of the operation with the earliest start date.You can uncomplete a Work Order after it is completed, bringing it back to a Released status.

Planners or Crew Supervisors can complete or uncomplete Work Orders using the Maintenance workbench, from the Work Plans tab in Maintenance User, or by accessing the Work Order Completion menu option.
