Setting Task Predecessors

The Predecessors tab enables you to set one or more 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 will begin when both 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.

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 has been marked as complete. This is primarily used for user tasks. For example, a user can start a document summary at any time, but cannot mark it complete until the consolidated data is final.

  To set task predecessors:

  1. From the New Task dialog, select the Predecessors tab.

  2. Click Add.

  3. Click Browse and select a predecessor task, then click OK.

    Tip:

    You can also select a different template or schedule from the dropdown list.

  4. From the Condition list, select a condition:

    • Finish to Start

    • Finish to Finish

    • Finish Error to Start

    • Finish Error to Finish
