You can relate actual projects to a sequence using the following relation types:

• Finish to Start. Target actual project cannot start earlier than the source actual project finishes.
• Start to Start. The target actual project cannot start earlier than the source actual project starts.
• Finish to Finish. The target actual project cannot finish earlier than the source actual project finishes.
• Start to Finish. The target actual project cannot finish earlier than the source actual project starts.

You can change actual project dates by moving an actual project across the timeline. The Actual Project Sequence validation rule is executed while changing the related project dates. If dates in the project sequence violate the rule, the relation is highlighted in red.
