You can manage precedence constraints in the Gantt view
to ensure that tasks are completed in a designated order.
About this task
A
precedence constraint is a relationship between
two work records that indicates when one task begins or ends in relation
to another. You can define precedence relationships between any tasks
that are siblings under the same parent work record. Some precedence
relationships are defined in the work management application where
the work record originated. You can edit constraints or add new ones
in the Gantt view. You cannot add constraints to preventive maintenance
forecasts.
Procedure
- To insert a precedence constraint, click Insert
Constraint
. The cursor changes to a
cross shape. To turn off the Insert Constraint button
without inserting a constraint, press the Escape key.
- In the Activity chart, click the first task in the constraint
relationship that you want to define, then click the second task.
A red line connects the two tasks that you specified.
- Right-click on the red line for the constraint that you
inserted. Select Edit Constraint.
- In the Edit Constraint window, select
the constraint type that you want to create. Then, enter any lead
or lag time that you want to include between the tasks. For example,
if you want to create a one hour delay between when Task 1 ends and
Task 2 begins, create a Finish-to-start relationship between Task
1 and Task 2, with a one hour lag. To delete a constraint,
select the constraint in the Activity chart, and then click Delete
Constraint
.
- Click Save Schedule
