About Trace Logic
Trace logic provides a graphical display of dependency relationships for an activity. You can step forward or backward through a sequence of activities to focus on predecessor and successor relationships. This alternative viewing format enables you to examine a path of relationships while still viewing the entire project.
Trace logic provides visual cues to help you read the diagram. The selected activity is highlighted in blue. Activity boxes with a red border represent critical activities. Activity boxes to the left of the selected activity are predecessors. Activity boxes to the right are successors. Solid lines represent driving relationships, while dashed lines represent non-driving relationships.
You can manage activity relationships using the detail windows or Gantt chart on the Activities page. You can view activity relationships in the Trace Logic detail window on the Activities page. You can use Trace Logic to determine why an activity is scheduled at a particular time. It also helps answer questions such as:
- Were any of the predecessors of an activity delayed?
- Do any predecessors or successors have an obsolete constraint?
- Are two activities that should be linked start to start currently linked finish to start?
- Why is there negative float?
