Making Configuration Changes

When you check out a project, the project remains locked in the server database and in your local database. This prevents other developers from checking out the project. During this time, you can make configuration changes using Siebel Tools, such as modifying user interface objects, extending business logic, and extending the database.

NOTE:  You can also lock projects locally, without checking them out from a server database. Read Locking Projects in Your Local Repository. This is how the procedures in subsequent chapters are written.
