Setting Task Predecessors
The Predecessors tab enables you to set predecessors for the current task. For template tasks, you can choose a predecessor from another template, and for schedule tasks, you can choose a predecessor from another schedule. You must assign a condition to the predecessor/successor relationship.
A task does not need predecessor tasks as long as a start date and time is specified. If both are specified, the task begins when the predecessor tasks are started or complete (for Finish to Start) and the start date and time is reached.
You can set these conditions under which the predecessor relationship is established:
Condition | Description |
---|---|
Finish to Start |
Default. The task starts as soon as the predecessor task completes or finishes with warning. |
Finish Error to Start |
The task starts as soon as the predecessor task completes, even if it is in error. |
Finish Error to Finish |
The task completes as soon as the predecessor task completes, even if it is in error. |
Finish to Finish |
The task cannot be marked as Complete until the predecessor task is marked as complete. This is primarily used for user tasks. For example, a user can start a document summary, but cannot mark it complete until the consolidated data is final. |
