Project Locks

When you open a project from CA Clarity PPM in Microsoft Project, you can open in the following modes:

• Read-only mode. When you open the project using this mode, a lock is not placed on the project. You can edit the project locally, but you cannot save the changes to CA Clarity PPM.
• Read/write mode. When you open the project using this mode, a lock is placed on the project. A project lock prevents users from updating the project and potentially overriding any changes made by the resource who is holding the lock.

When you lock a project in CA Clarity PPM:

• You hold the lock until you close the project. You can update and save the project, and continue updating the project without losing the lock. The action lets you update projects locally for extended durations and also to share the updated information with other users.
• Other users can open the project as read-only. They can update locally, but they cannot save the project to CA Clarity PPM. In Microsoft Project, when you force a save, a warning message appears that changes after opening the project can get overwritten.
