Dependencies Tab

Use the Dependencies tab to:

Link one or more activities.
Define relationship between activities.

You can also enter predecessor dependencies between a selected activity and another activity. The dependency relation is used to automatically shift activity dates forward or backwards based on changes to the predecessor. This is also reflected in the Gantt chart.

In the predecessor section, you can add predecessor activities, in bulk, by using the Add option in the predecessor section. In the successors section, you can add the successors, in bulk, to a selected activity by using the Add option in successors section.

Predecessors block

The ID column displays the activity ID of the predecessor for the current activity. The ID column is added by way of the Add option, in the toolbar. This field is editable, and you can change the activity ID. If you enter a value in the ID column in the grid and that activity ID does not exist, the system displays an error message. You can only enter alphanumeric characters in the ID column.

Activity Name

The value in the Activity Name column is populated with the activity ID that was entered. This is a read-only column in the grid, and you cannot enter or edit the Activity Name column value.

Relationship

The following relationship types are supported:

Finish-to-Start
Finish-to-Finish
Start-to-Finish
Start-to-Start

Lead/Lag (days)

The Lead/Lag (days) column enables you to specify the number of days the activity can start ahead (lead), or delayed (lag), by mentioning the number of lead or lag days. This is an integer type field which allows both the negative and the positive integers.

The lead days will be provided by specifying the negative number, and the lag days can be provided by specifying positive number (specifying the days that the successor activity can be delayed to start).

When you click Add, a picker with a list of all activities that were defined in the activity sheet will be displayed. This list does not include activities which are successors and current activity. Can select one or multiple activities as predecessors. The default relationship shown in the grid is Finish to Start after the user adds the activities.

User should be able to select the relationship between the predecessor and current activity by choosing the relationship drop-down and lead/lag days.

The same functionality as seen while adding predecessors is applicable in the case of adding successors in the Dependencies tab.

Successors block

The activity ID column displays the activity ID of the predecessor for the current activity. This is added via the Add action on the tool bar.
