Chapter 8. Work Management 143 An action in the Work Order Tracking application allows the editing of history information about work orders when they are in the closed status. The Edit History Work Order action enables certain information to be edited, including tasks. Labor, materials, services, and tools are not allowed to be edited. The limits to change work order data, considering work order status, are provided by default in IBM Maximo Asset Management, however they can be edited by using the Edit Rules action in the Organizations application. 8.1.2 Work plans A work plan describes the labor, materials, tools, services, and tasks necessary to complete a work order. Selecting a job plan to a work order, modifying the work plan to the requirements, or creating a work plan manually are possible. The Plan tab in the Work Order Tracking application contains all the definitions necessary to create a work plan. You may define tasks and flow sequence for tasks, and request labor, materials, services, and tools. To add, remove, and modify a work plan regarding labor, materials, services and tools, the work order has to be in the WAPR status. However, to add, remove or update tasks, the work order cannot be in the CAN or CLOSE status. Tasks also define their own status, which is not necessarily the same defined in the work order. A task can be edited considering the work order status and its status. A task only can be removed if it is at the WAPR status. If some labor is reported for a task, the status is automatically changed to APPR, not allowing labor removal. Figure 8- 1 on page 144 shows an example of a work plan. It defines a series of tasks to be performed. Also, it has two planned laborers to do the work. Note: A work order is created and planned in the Waiting on Approval status. After work is started, it enters the Progress status. When the work order is done, it is in a Completed status and can be closed.
