In logical model I have a relation with delete rule no action. In relational model the fk rule is cascade.
When engineering to relational model the difference is seen but not applied (compare/copy option is set).

DM does not see the difference in delete rule as a change?

How can I engineer the change in delete rule to relational model? Is there some other setting required to make DM see this as a change that needs to be engineered?
Using DM 4.1.3 (same behaviour seen in 4.1.5)
