Description:
When working with a model in erwin Data Modeler, that has an excessive number of relationships, especially when one or more Entity / Table in the model has 60+ Relationships, the bulk editor may hang for a long time or become totally unresponsive.
Solution:
There are known performance issues in erwin that are caused by models with one or more Entities/Tables having excessive (>60) Relationships each). This can include performance opening, navigating, and editing models, including features such as bulk editor. A workaround is to create a new blank ER Diagram and launch the bulk editor Wizard from the blank diagram. The bulk editor should now work as normal.
