Link/Unlink Activities Dialog Box

Use this dialog box to add and remove multiple relationships of the same type between activities conveniently.

Clicking the Link button automatically creates relationships between selected activities using the selected type, lag, and calendar.

When you use Ctrl + Click to select and link activities, Open Plan links the activities in the order in which you selected them. For example, if you use Ctrl + Click to select three activities in the order shown below, Open Plan links 1.03.05 to 1.03.02 to 1.03.06.

Field Description
Relationship Type

Select one of the following relationship types:

  • Finish to Start:  The relationship between activities that specifies that the start of the successor activity depends on the completion of the predecessor activity. In most cases, this means that the successor activity cannot start until the predecessor activity is completed. This is the default relationship.
  • Start to Start:  The relationship between activities that specifies that the start of the successor activity depends on the start of the predecessor activity. In most cases, this means that the successor activity cannot be started before the start of the predecessor activity.
  • Start to Finish:  The relationship between activities that specifies that the finish of the successor activity depends on the start of the predecessor activity. In most cases, this means that the successor activity cannot be completed before the start of the predecessor activity.
  • Finish to Finish:  The relationship between activities that specifies that the finish of the successor activity depends on the completion of the predecessor activity. In most cases, this means that the successor activity cannot be completed before the predecessor activity is completed.
Note: By default, this field displays Finish to Start.
Lag

Enter a time delay associated with a relationship in a project. This field supports positive, negative, and percentage lags. By default, this field displays zero (0).

Open Plan only allows a percentage lag on the Start-to-Start relationship type. When you enter the percentage lag for a different relationship type, an error message displays.

Calendar

Select a calendar upon which Open Plan bases calculations for any lag in the relationship. The drop-down list contains all calendars defined in the calendar file including <Calendar of Successor> and <Default>. By default, it displays <Calendar of Successor>.

Link

Click this button to create relationships between selected activities. Open Plan then creates relationships between the selected activities using the relationship type, lag, and calendar that you specified on the dialog box.

If relationships already exist between the selected activities, Open Plan does not allow you to modify the existing relationships.

Unlink

Click this button to remove relationships among the selected activities.

Open Plan displays all errors that occur when linking or unlinking activities on the Link/Unlink Activities Errors dialog box after the process completes.
