Class Recursiveness (SAP Library

Class Recursiveness

The Detail Screen: Class Recursiveness is only relevant to class items whose class type is linked to the material master. Here, you control the recursiveness check for a class item. For other item categories, you maintain this data on the Detail Screen: General data.

On the Detail Screen: Class Recursiveness, the system lists all objects which are allocated to the class entered as a class item. If this class has a class allocated to it, and this subordinate class also has materials allocated to it, these materials are also displayed on this detail screen.

Note

If the class used as a class item is part of a class hierarchy, the hierarchy is exploded down to the lowest level.

Recursiveness Check

When does the system recognize class recursiveness?

The system recognizes recursiveness for a class item if the following objects are allocated to the class in the class item:

The BOM header material

A material with a BOM which contains the BOM header material as an item

A class to which one of the materials described above is allocated

Note

The recursiveness check includes all BOMs in a BOM group.

Fields for the recursiveness check

For class recursiveness, you maintain the following fields in the Recursiveness dataset:

Selection indicator (S)

The system uses this indicator to select the components that cause recursiveness and for which you need to define the recursiveness check.

Component

This field contains the material number of a component if:

The component is allocated to the class entered as an item
The component is allocated to a class in the class hierarchy that is below the class entered as an item

Class

In this field, you see the class type and the class to which the component is allocated.

If this class is the same as the class in the class item, the material is allocated directly to this class. Otherwise, this class is allocated to a class in the class hierarchy that is below the class entered as an item.

Indicator: BOM is recursive (Rec)

The system automatically sets this indicator when it recognizes recursiveness.

Allowed

If you enter a class as a class item and at least one material allocated to the class causes recursiveness, you see the Detail Screen: Class Recursiveness. In the first line, you see the first material that causes recursiveness. You must decide whether recursiveness is allowed for this material.
If you set this indicator for one of more of the selected components, the system returns to the Detail Screen: New Material Items. You can then continue processing.
