A cost category is a classification of costs that are related to an operations resource or a routing operation1. A cost category can have one or more cost elements, such as labor, machine, subcontractor, or material1. A cost element represents a specific type of cost that is incurred for an operations resource or a routing operation2. To update the effective labor costs for all labor groups, you must update the cost category that is assigned to the labor groups. You can use the Cost categories page to modify the cost elements and rates for the cost category3. You can also use the Costing versions page to create a new costing version with updated cost categories and activate it for future production orders.
