Overview of Customizing Objects

You can edit workspace-enabled repository objects directly without locking any project. Note that only workspace-enabled repository objects can be edited inside workspaces. By default, all workspace-enabled objects are locked at the database level. Therefore, you are not required to lock projects when you edit the objects or perform any type of CRUD (create, read, update, delete) operation.

However, locking a project is still required before you edit the non-workspace objects. The non- workspace objects are Table, Task, Repository, Type, EIM Table, Projects, Dock Objects, Schema Maintenance, and Server Components.
