Selection from a Class Item: Example 
Define the following additional data for the class:
· The class can be used in bills of material (BOMs).
· The base unit of measure is piece.
· The item category for the resulting material is L (stock item).
You classify there 3 materials in class REARLIGHT as shown in the following table:
Material |
Value |
R1220 |
Dtoplight Plus |
R1221 |
Toplight |
R1222 |
FER |

When you enter the BOM item, enter item category K first. You see a dialog box in which you must enter the class name and class type.
The class name for the item is not shown on the material item overview.
The characteristic is now assigned to both the class item and the configurable material.
Depending on the value you assign to the characteristic, the relevant material is selected from the class item.
For example, if you assign value ‘Toplight’ to characteristic REARLIGHT_TYPE, the class item is automatically replaced by material R1221.
