IFS/Manufacturing allows the definition of Labor Classes to represent labor used on shop order operations. This is a classification of labor, not a specific instance. Labor Classes are defined for a manufacturing site and have definable work time associated by manufacturing calendar identifier. The CBS Scheduled value represents whether the constraint based scheduler will schedule the labor for production in conjunction with the schedule capacity with a value of Finite Capacity. The Cost Center value (if entered) indicates the cost center ID to which the labor class belongs.
