The Impact and Lineage tab displays the result of the analysis in a tree format, showing all the impacted and lineage objects. Each item in the tree displays either an [action] suffix to indicate the effect on an impacted object or a [lineage] suffix to designate lineage items
In this example, the analysis shows that:
- A change on the Participate entity will result in changes to the Task and Employee entities with which it has relationships (and that the change will cascade down from the Task entity to the Project and Customer entities).
- The business rules Task date control and Participate date control form part of the definition of the Participate entity, which was generated from the Participate table in Project Management (PDM).
Note:
If an object is dependent multiple times then, for performance reasons, only the first entry appears in detail in the tree. Right-click subsequent undeveloped entries and select Go to First Occurrence to jump to the detail.
