Undoing a Data Dictionary Check Out
Go Up to Working with Data Dictionaries in the Repository
The Undo Check Out operation transfers the latest version of the Diagram or Object from the Repository to your machine. You can view the Diagram, but is no longer able to modify it.
Choose Repository > Data Dictionary > Undo Check Out Data Dictionary.
Note: When you undo the check out of a data dictionary, any changes made to the Diagram before doing the Undo Check Out operation are discarded.
