Description: In erwin Data Modeler, I open a model, select Actions | Model Naming Options | Duplicate Names. I see that ‘Allow Duplicate Names’ is selected. I try to change an Attribute/Column Name to match another Attribute/Column Name and can't because erwin requires names to be unique. What else do I have to do to get the Allow Duplicate Names to work?
Solution: That is by design. 'Allow Duplicate Names' means in other Entities/Tables, not in the same Entity/Table.
You can’t have the same Attribute/Column Name appear twice in the same Entity/Table.
