Create cross-schedule dependency
You can create dependencies between tasks in different schedules, including the top-level summary tasks in the Schedule Manager application. The schedule may be part of the same master schedule or in entirely separate schedules.
Note: You cannot create a cross-schedule dependency between a schedule template and a non-template schedule.
Note: You cannot create a dependency between a published schedule and an unpublished schedule, even if you are the creator and owner of both schedules.
Procedure
Select a task in an original schedule you created.
Choose Schedule → Link → Create Cross Schedule Dependency.
Teamcenter displays the Select a Schedule page in the Create Cross Schedule Dependency wizard.
Select the schedule on which to depend.
Click Next.
Teamcenter displays the Select a Task page.
Select the task on which to depend.
Click Next.
Teamcenter displays the Create a dependency page.
Select Successor or Predecessor from the list.
Select a dependency type from the Dependency Type list.
Select a value from the Lag list.
Click Finish.
The proxy task appears grayed out.
Results
You can also create this dependency by creating a proxy task first, and then linking it to another task.
