Operation 
Definition
Used in a routing, to describe the activity that is to be carried out during a process step.
Use
Operations are the central object in routings. The system uses operation data to determine dates, capacity requirements and costs for a production process.
Structure
Depending on your requirements, an operation can contain the following data:
A control key, which determines
Whether the operation is processed internally or externally by a vendor.
Whether dates, capacity requirements and costs are determined
Whether, afterwards in order processing, a confirmation can or must be made
A wage type for settling incentive wages
External processing data , which form the basis for externally processing sub-operations, including scheduling and costing
Standard values , which are planned values for the activities to be performed in a sub-operation.
User-defined fields with any customer-defined data
Inspection specifications for quality inspection during the operation
Operations
The operation data includes:
The p lant in which the operation is to be carried out
An operation that is not to be carried out in the plant in the routing can be assigned to another plant. Both plants only have to belong to the same controlling area.
The work center where the operation is to be carried out
Standard values for determining dates, capacity requirements and costs
Integration
Plant
An operation that is not to be carried out in the plant in the routing can be assigned to another plant. Both plants only have to belong to the same controlling area.
Work center
Usually an operation is assigned to a work center where it is carried out. If standard values have been maintained in the work center, they are copied to the operation. If you set a reference indicator, you stipulate that a standard value can only be changed in the work center. This change is automatically transferred to the routing.
Subordinate routing objects
The following objects can be assigned to an operation at a subordinate level (see graphic below)
Sub-operations , with an operation can be described in a more detailed manner
Material components , that are used to manufacture the finished product
Production resources and tools necessary for executing the operation
Inspection characteristics for quality inspections during the operation
Trigger points , for triggering certain functions when an operation is carried out
