Cross Project Predecessors

Microsoft Project lets users link tasks within the current project, or to external projects. Cross-project predecessors are predecessors from another project. Aspose.Tasks support these too.

Working with Cross-Project Predecessor Tasks

In Aspose.Tasks for Java the CrossProjectName and IsCrossProject properties exposed by the TaskLink class are used to handle cross-project predecessors.

To manage cross-project predecessor tasks in Microsoft Project from the Tools menu, select Links between Projects.
