You are involved in implementing the SAP Defense and Security industry solution. You need to learn about the Defense and Security-specific work center integration.
In Plant Maintenance (PM), work centers are used in the following ways:
- As the main work center in the master record for the equipment or functional location.
- As the main work center in a maintenance item.
- As the main work center in the task list header.
- As the performing work center in the operations for a task list.
- As the main work center in the order header.
- As the performing work center in the operations for an order.
Work centers belong to the master data in PM and provide the capacity required to perform a task.
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, you must calculate the time required for the operations and compare it 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 the available capacity and capacity requirements of lower-level work centers.

Work center links provide the connection between work centers and other objects within the SAP System. You can link a work center to the following objects:
- Cost center
- Qualifications
- Staffing positions
- People
