Since operation A10 is not copied to the worklist, the system only determines the environment objects for the focus object, operation A30 (see Environment Objects graphic):

1. All objects that are either superior or subordinate to operations A10 and A30, i.e. header A, sequence 0 and PRTs F and H.
2. All items that are assigned to these operations, i.e. items B10 and B20. Also, the component assignments between A10 and B10 and A30 and B30.
3. All objects that are superior or subordinate to items B10 and B30, i.e. BOM header B.
4. The assignments between material M and header A or BOM header B.
