Project Locking with Object Manager

Opening a connection to a project with Object Manager causes the project metadata to become locked. Other users cannot make any changes to the project until it becomes unlocked. For detailed information about the effects of locking a project, see Lock Projects.

If you need to allow other users to change objects in projects while the projects are opened in Object Manager, you can configure Object Manager to connect to projects in read-only mode. You can also allow changes to configuration objects by connecting to project sources in read-only mode.

Connecting to a project or project source in read-only mode has the following limitations:

A connection in read-only mode may not display the most recent information. For example, if you view a folder in Object Manager in a read-only connection, and then another user adds an object to that folder, the object is not displayed in Object Manager.
You cannot copy objects into a read-only project or project source. If you connect to a project in read-only mode, you can still move, copy, and delete objects in a project, but you cannot copy objects from another project into that project.
By default, users cannot create update packages in read-only mode. This is because objects, and their used dependencies, may be changed between the time they are selected for inclusion in the update package and the time the package is actually generated. If necessary, you can configure Object Manager to allow the creation of update packages in read-only mode. For information about update packages, see Copy Objects in a Batch: Update Packages.
