Freezing and Unfreezing Document Versions

Unlike many repository systems, the PowerDesigner repository does not require you to create a new version of a document each time you check it in. You create a version only when you want to, by freezing the document.

Freezing a document creates a version in the repository that you can go back to and view its state at the point in time when it was frozen. You could choose to freeze a document (and thus create a new version) each time you check it in, once a day, once a week, or at any other interval.

Note: To freeze a document, you must have the Freeze versions right (see Granting Rights to Users and Groups) and the appropriate permissions on the document.

You can freeze a document during check in (see Checking Documents into the Repository) by selecting one or both of the following options:

Freeze before check in - to preserve the state of the model before your changes
Freeze after check in - to preserve the state of the model including your changes (this option can be selected by default if you select the Freeze after check in general option (see Repository Options.

If you have the Write or Full permission on a document that is frozen, you can unfreeze it's most recent version. Unfreezing a document version allows you to make further changes to the existing version, but means that you will no longer be able to go back and view the previously frozen state.

You can freeze a document or unfreeze its latest frozen version at any time by:

Right-clicking the document, folder, project, or root node and selecting Freeze or Unfreeze.
Note: To freeze or unfreeze all the documents inside a folder or branch, right-click it and select Freeze or Unfreeze. You must have the appropriate permissions on all the contained documents.
By clicking the Freeze or Unfreeze tool on the property sheet of a:
- Document - on the Versions tab.
- Configuration - on the Members tab.

Note: You cannot individually control the freezing and versioning of PowerDesigner model objects. Each changed object has its version frozen and version number increased by one each time you freeze its parent model's version.
