When you make modifications to objects and need to update one or more libraries, you should use the Rebuild option to update all the library objects in the correct sequence.
There are two methods to use when you rebuild an application:
Incremental rebuild updates all the objects and libraries referenced by any objects that have been changed.
Full rebuild updates all the objects and libraries.
To rebuild libraries:
Select the libraries you want to rebuild.
Depending on your needs, choose either Design>Incremental Build or Design>Full Build from the menu bar.
