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

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

You can change project dates by moving a 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.
