Modify Internal Task Dependencies

The Dependencies tab on the Task Properties dialog displays dependency relationships for the selected task, including internal and external dependencies. You can use this tab to edit the dependency relationship and to add new dependency relationships.

Note: If you specify percent as the lag type and Finish-Finish as the constraint type, you are specifying the percentage of the successor's duration. If you specify percent for any other constraint type, you are specifying the percentage of the predecessor's duration.

Overlap Tasks

If you want two tasks to be scheduled on the same day because the resource has remaining availability on that day, enter -1.00 as the lag to overlap the tasks.

Zero Lag

To schedule two dependent tasks, schedule first on one day and the next on the following day, enter zero as the lag amount.

Follow these steps:

1. Right-click the task from the view and click Dependencies.
2. Select the task you want to modify from the Project Tasks list, and modify the following fields:

   Pred/Succ

   Specifies the task's dependency relationship.

   Default: Successor

   Options: Successor or Predecessor

   Type

   Specifies the constraint type to be placed on the task's start or finish date.

   Default: Finish-Start

   Options: Start-Start, Start-Finish, Finish-Start, or Finish-Finish

   Lag

   Defines the number that represents the days or percent to indicate the amount or time between, or overlapping, the task start or finish dates.

   Note: The constraint type used is the type you specify.

   Lag Type

   Specifies the lag type.

   Default: Daily

   Options: Daily or Percent

3. Click OK.
