The design build path defines a hierarchy of the projects involved in the location. It is used to resolve the links between the instances of the various projects included in the location.
To resolve the links, the design build path explores the projects hierarchy. It applies to all the instances of the location. If it is not defined, the resolution of the links is limited to the current project. Hence, calling an instance located in another project of the location is impossible and a reference search only retrieves the results found in the current project.
The project from which you open an instance or generate it is the starting point for the upward exploration of the design build path. This project constitutes the work context of the instance.
If you used the Pacbase migration procedures to import your instances into the location, the design path is automatically defined according to the hierarchy of the Pacbase Libraries. However if you created your projects and instances from scratch, you must specify the projects hierarchy in the Design build path wizard available from the location.
To be shared, the design build path must be saved onto the Rational Team Concert™ server.
