Maintenance Work Definition Structure

A maintenance work definition consists of the following elements:

• Operations

• Operation Items

• Operation Resources

The work definition's operations are executed following a linear path based on the operation sequence. A work definition must have at least one operation and it must be associated to a work center. You can either use predefined standard operations or you can manually define and enter each of the operations. We recommend you create and use standard operations wherever possible, allowing them to be reused across different work definitions.

Note: To define a global definition, you must ensure that all the child objects match by name and code across all maintenance organizations, else the replication will error out for the organization.

Typically for asset maintenance, each operation is defined as including a count point. This means that the operation is expected to be executed by a technician, indicating they have completed each of the steps of the operation. During this time, any additional material, resources, or meter readings can be entered.

If an operation is not identified as a count point, then it's automatically transacted when the next count point operation is completed. These operations are typically defined to trigger the backflush pull-type items and even charge pre-defined resource usage.

Alternatively, if an operation isn't indicated as a count point or an automatically transact operation, then it's considered as an optional operation. In this case, there's no action required by the technician during execution of the work order. This capability is available, but typically not utilized for most maintenance work order operations. However, there may be some cases where common tasks that don't require manual reporting can be modeled without any count points, thus they will automatically be completed once the work order is released for execution.

Note: When defining Global work definitions, you must first ensure common data is defined at all the child organizations, else replication will fail.

Operations

The work definition operations define the sequence of steps to be performed in maintaining an asset. The operations are executed following a linear path based on the operation sequence. A work definition must have at least one operation and the operation must be associated to a work center. You can either use standard operations, or you can manually define the operations. If an operation isn't indicated as a count point or an automatically transact operation, then it's considered as an optional operation.

Operations can also be worked out-of-sequence if enabled at the work definition header. This allows count point operations in the My Maintenance Work page to be completed in any order.

Operation Items

The operation items define the material requirements for operations. Non-asset tracked items will be consumed and costed by the work order, while asset-tracked items will be installed on the work orders asset’s configuration and will be visible in the physical hierarchy.

Operation Resources

The operation resources define the resource requirements for operations. The pool of resources available comes from the work center assigned to the operation. A resource represents either a labor or equipment that performs or assists in the accomplishment of the operation step.

Note: If you use a referenced standard operation, then you can't add, edit, or delete the resources, as the resources are a part of the standard operation definition. You must update the resources on the Manage Maintenance Standard Operations page.

Operation Parameters

The operational parameters tab is enabled by a manufacturing opt-in feature and will be used in a future version by maintenance. See the Implementing Manufacturing and Supply Chain Materials Management guide for more details.
