Parameters for Quantity Structure Control
Use
There are various ways to influence how a quantity structure is created. This section details the parameters with which you can control the quantity structure data.
Features
Quantity Structure Control
The quantity structure control controls how the system searches for alternatives when there is more than one BOM or routing for a material. You define the quantity structure control in Customizing and enter it in the costing variant. For more information, see Quantity Structure Control Through Customizing and Preparing for Material Costing.
Transfer Control
This determines
You define the transfer control in Customizing and enter it in the costing variant. For more information, see Transfer of Existing Costing Data.
Reference Variant
The reference variant enables you to create a cost estimate using the quantity structure of an existing cost estimate as a base. The quantity structure of the cost estimate referenced is transferred and is not exploded afresh. You define the reference variant in Customizing and enter it in the costing variant. For further information, see Reference Costing.
Date Control
The system uses the date control to propose the date on which the routings and BOMs are exploded. You define the date control in Customizing and enter it in the costing variant. For more information, see Date Control.
The following figure shows how the costing variant combines all the control parameters for cost estimates. In addition to the other key parameters (such as the valuation variant and costing type), the costing variant contains the control parameters required for the quantity structure. These are the quantity structure control, transfer control, date control, and reference variant.
Control Key in the Operation of the Routing
The control key of an operation in the routing specifies whether the operation is to be included in costing. You define the control key in Customizing and enter it in the operation in the routing. To cost the operation, you must set the Costing indicator. For more information, see Routings in Costing.
Furthermore, you must mark the operation as relevant to costing (X) in the routing. Operations that are not marked as "relevant to costing" are ignored - even if the control key of the operation allows costing.
