Is subordinate to an operation and is used for more detailed planning of the process step that is described in the operation.
For example, you can use sub-operations to assign several people or machine that are required at the same time, to an operation. An sub-operation can be costed, but can only be scheduled relative to superior operation. You can cumulate standard values from sub-operations on the corresponding operation. You can determine whether sub-operations belonging to an operation are copied into the production order.
Depending on your requirements, a sub-operation can contain the following data:
A control key, which specifies
Whether costs are determined for the sub-operation
Whether the sub-operation is processed internally or externally by a vendor.
Whether, afterwards in order processing, a confirmation can or must be made
A wage type for settling incentive wages
Standard values, which are planned values for the activities to be performed in a sub-operation.
External processing data , which form the basis for externally processing sub-operations
User-defined fields with any customer-defined data
Operation
An operation that is not to be carried out in the plant in the operation or routing can be assigned to another plant. The plants only have to belong to the same controlling area.
A sub-operation can be assigned to another plant as its superior operation.
The unit of measure in the sub-operation can differ from the one in the operation.
Subordinate routing objects
You cannot assign material components, production resources/tools nor inspection characteristics to sub-operations, only to operations.
