This error occurs when a persistent type that does not participate in Vertical Inheritance is set up explicitly to use (or not use) cascade delete. In other words, the value of its Use Cascade Delete property is Yes (or No).
To resolve this warning, the value of Use Cascade Delete for the type should be set to Default. You can do this by either changing the property value in Property Window and saving the domain model or following the next steps:
- Double-click on the warning message in Error List to open the Resolve Validation Errors Dialogue
- Select AUTOMATIC: Set UseCascadeDelete property of the class to 'Default".
- Click the Fix Selected button
- Save the domain model
