You can edit a class to change the name, description, icon file name, or lineage properties. If you edit a class to show the metadata objects for the class in data lineage, you must load the resource again to view the metadata objects for the class in the data lineage diagram.
To edit a class:
On the Model tab, select the class in the Model navigator or Content panel.
In the Properties panel, click the Edit icon.
The Edit Class window appears.
Edit the class properties.
Click OK.
Metadata Manager updates the class with the changed properties.
