You are working in the area that is described under Example: Working Area

Presume operation A10 is the only externally processed activity that you have created and you are using the selection criterion "externally processed". The Focus objects in the worklist are, in other words, all operations that satisfy the selection criterion. This means that operation A10 is the only focus object (see white area in the graphic).

The environment objects in the worklist are all objects that are related to operation A10 and whose object type is contained in the working environment (light gray area). For instance BOM header B is an environment object.

Objects that are linked to operation A10, but whose object type is not in the working environment (gray patterned) are not contained in the worklist, for instance trigger point F.
