A control key uses the following keys and indicators to determine how an operation or a sub-operation is to be processed in a task list.
The following parameters shall be set in the control Key:
Scheduling: The system carries out scheduling for an operation or it determines the earliest or latest dates for a sub-operation.
Capacity planning: The system creates capacity requirement records for the operation or sub-operation.
Costing indicator: Set this indicator to specify whether the operation or the sub-operation shall be relevant for costing or not.
Confirmation: Set this indicator to specify whether and how the operation or sub-operation shall be confirmed.
Print operation: Set this indicator to specify that shop papers are printed for the operation or sub-operation.
External processing: Set this indicator to specify that the operation or sub-operation is to be performed by external system or person. In this case, a purchase requisition is generated during order creation.
The control key is assigned either in the Work center / Resource or assigned directly in the Routing(for each operation) / Master Recipe (for each operation/phase).
