Frozen items listing
If you try to open an object, such as a diagram, that has been frozen, the message
[Object type object name] is in use by [name of supervisor who froze the object]
is displayed. The object is available in read-only mode. Diagrams display the date, time and Audit Id of the person who froze them. No one has write access to a frozen object.
To obtain a listing of all frozen items, run the Frozen Diagrams and Definitions report. This report is included in the REPORTS.RPT file.
