Selecting Materials for the Costing Run 
Use
After you have created the costing run, you can select the materials to be costed. How you select the materials depends on whether you work with closed BOMs (which cannot be configured) or open (configurable) BOMs.
For materials that are often produced in the same way, BOMs and routings for each material are defined in Production Planning.
For multi-variant products, BOMs and routings are defined in the PP component for what is called a standard product. You create a material master record that refers to the standard product for every variant of the standard product. You create a BOM and a routing for the standard product. You also define dependencies between the different components in the BOM and the activities in the routing. On the basis of these dependencies, the system can determine precisely which BOM components and routing activities are required to produce the variant.
Prerequisites
You have
created the costing run.Procedure
(Change parameters).The screen Costing Run: Selection - Change Parameters appears.
In the costing run, you can use the transfer control ID to specify whether existing cost estimates are transferred for certain materials. By doing so, you can prevent the materials from being reselected for costing. To be able to recost all materials in the BOM, you can set the Always recalculate material indicator for the selection. This restricts the transfer control function.

If you work with open BOMs, you must carry out the processing step Selection to select the configured materials in a plant. Standard products have the material type KMAT and cannot be costed.
The BOM for a configured material does not usually consist of configured materials only. To increase performance, you can do the following:
