Main function of Work center

  • Costing: You can use costing to determine the costs of an internal activity by a product unit. The aim of costing is to attribute the costs incurred to the individual cost objects. It uses the work center to link the operation to cost accounting by maintaining cost centers and activity types. If the work center is used in an operation, standard values can be entered for the activity types specified in the work center.
  • Scheduling: You can use scheduling to determine the dates when operations should be performed. For this, the time required for the operations must be calculated and compared with the time available in the work center. The standard values and quantities in the operations are used as the basis for this calculation. During scheduling, the start and end dates for the operations are calculated from this data using formulas, which have been entered for scheduling in the work centers.
  • Capacity planning: In capacity planning, the capacity requirements for the operations in the orders are determined and compared with the available capacity defined in the work center. During capacity planning, you can use work center hierarchies to aggregate (at higher-level work centers) the available capacity and capacity requirements of lower-level work centers.
