Selection from a Class Item

Use

You have various options for selecting a specific material or document from a class item (sometimes called "specializing" a class item).

• The class item is automatically replaced according to the characteristic values assigned when the material is configured.

• This means that object dependencies for the class item must make values for the characteristics of the class known.

If the system finds no values for the characteristics in the class item, first it looks for the values in the superior assembly, then if it finds none there, it checks the header material.

• In a multilevel, interactive configuration, the class item can be replaced manually by searching for an object.

However, this is only possible in the simulation, or in configuration processes Order BOM and Sales order (with the setting Manual changes allowed).

Components that are automatically selected from a class item cannot be changed manually in order BOM processing or set processing.

Required Component

If you define in the class or the BOM item data that a component must be selected (Required component), the class item is marked as inconsistent until it is replaced by a material or document.
