Estimating the costs of maintenance Work Orders is often necessary for planning and assessing purposes. The Work Order Cost Estimate Processor estimates the costs of all materials and resources exploded or entered on a maintenance Work Order, enabling you to plan and assess your costs. A Work Order's estimated and actual costs might differ because all materials or resources, associated with a Work Order, might not actually be used when the Work Order executes. For example, a required material was not issued to the maintenance Work Order.
Cost Estimation Lifecycle

The Work Order Cost Estimate Processor can continually execute or launch manually via a concurrent request. Work Orders have one of the following Estimation Statuses:
Pending - The Work Order is waiting to be selected by the Work Order Cost Estimate Processor.
Running - The Work Order Cost Estimate Processor is currently estimating the costs of the Work Order.
Error - The Work Order Cost Estimate Processor attempted to estimate the Work Order's costs, but there was an error.
Complete - Work Order Cost Estimate Processor successfully completed estimating the Work Order's costs.
Re-estimate - The Work Order is waiting to be picked up by the Work Order Cost Estimate Processor, for re-estimation. In this case, the Work Order was estimated at least once.
Running and Re-estimate - Changes were made to a Work Order's requirements, while the Work Order Cost Estimate Processor was executing. These Work Orders are then re-estimated by the Work Order Cost Estimate Processor.
Navigate to the Maintenance Work Orders window.
Select the Work Orders to estimate/re-estimate by selecting the individual Select & Estimate check boxes. You can choose Select All to automatically select all Work Orders listed for re-estimation.
Choose Re-estimate Work Order to estimate/re-estimate all selected Work Orders.
The Estimation Status field displays the status of the Work Order Cost Estimation process.
