Assignment of Task Lists to a Maintenance Item
Use
In the
Plant Maintenance
application component, maintenance task lists are used to process planned and unplanned maintenance tasks. Maintenance task lists describe the individual steps which must be executed for inspections, repairs and preventive maintenance. In addition, they list the spare parts and tools required for the job, and specify the necessary completion time.
You include this information if necessary in a maintenance item by assigning a task list to it. If you work with strategy plans, enter a maintenance strategy in the task list. This means that you can assign the maintenance packages of the assigned maintenance strategy to individual operations in the task list. For example, you assign the maintenance package "every 6,213.71 miles" to the operation "oil change".
Through the assignment of maintenance packages to operations, you define the frequency (in this case, every 6,213.71 miles) in which the operations should be performed. The operations described in the task list are performed on all the technical objects which have been assigned to the maintenance item (see Object List ).
You can automatically copy operations from task lists into an order. For further information, see Worklist for Notifications and Assigning a Task List to a Notification .
Prerequisites
The following prerequisites must be fulfilled:
For time-based and performance-based maintenance plans with a strategy, the task list and the maintenance item must have the same strategy.
The status
Released
must be set for the task list.
Features
You can assign an existing task list to a maintenance item or alternatively, you can create a general task list, an equipment task list, or a function location task list directly from the maintenance item.
On the detail screen for task lists, you can also enter the following data:
Task list factor
The task list factor specifies how often a task list should be performed.
Example
You have created an elevator, which you must inspect according to industrial standards, as a piece of equipment. The assigned task list describes the operation "Check elevator door mechanism". You enter "5" as the task list factor because the elevator stops on five floors and you must check five elevator doors in total.
The system automatically projects the labor time and material components assigned to the task list.
System condition
The system condition indicates, for example, whether or not a technical system can be in operation during the maintenance task.
Example
If a maintenance order is generated from the maintenance item, then the capacity requirements records for the assigned PP work center (work center for the
Production Planning
application component) are generated. The production planning sees when maintenance is to be performed and whether or not the technical object concerned, for example, a production system, can be in operation during the maintenance work.
