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

• The focus is the object type operation.
• The working environment consists of the object types material, material-routing assignment, routing header, sequence, sub-operation, material - BOM assignment, BOM header, item 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 operation A20 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 superior or subordinate to operation A20, that is header A, sequence O and sub-operation A21.
2. All items that are assigned to operation A20, items B20 and C20. The component assignments between these items and operation A20.
3. All objects that are superior or subordinate to items B20 and C20, the BOM headers B and C. The sub-items B21 and C21 are not copied, since object type Sub-item is not in the working environment.
4. The assignments between material M and the routing header A as well as the BOM headers B and C.
