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:
Note:
Event Monitoring tasks can not have predecessors; however they can be predecessors to other types of tasks.
Table 8-1 Predecessor Conditions
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 it is in error. |
Finish Error to Finish |
The task completes as soon as the predecessor task completes, even 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. |
