In the graphic the working area consists of the focus (white ellipse) and the working area (gray).

• The focus is the BOM header object type.
• The working environment consists of the object types material, material-routing assignment, routing header, sequence, operation, sub-operation, material-BOM assignment and component assignment.

The PRT, trigger point, inspection characteristic and sub-item object types are not contained in the working area (they are in the gray patterned area). As a result the system does not, for example, copy any sub-items into your worklist.

The Objects in the database graphic shows you which objects already exist in the database.

Assuming that only BOM header B meets your selection criteria, and is thus the only focus object, the system selects the following environment objects (see Environment objects graphic).

1. All objects that are subordinate to BOM header B, the items B10 and B20. The sub-items for these items are not copied, as the object type sub-item is not in the working environment.
2. Routing header A that is assigned to BOM header B. The assignments between material M and BOM header B or routing header A.
3. All objects that are subordinate to header A, i.e. sequence 0, the operations A10 and A20 and the sub-operations A11 and A21.
4. All component assignments between the aforementioned operations and items.
