I created some views in my logical model. After I engineer them to relational model, they appear in relational with an exclamation mark near the upper left corner. If I try to generate ddl for them, I get an error (-- ERROR: Invalid View VwTest). I realized that I have to "validate selected views", in order for the eclamation mark to disappear, and then I am able to generate ddl for them. After that, when I engineer from logical to relational again, it always shows me that my views are different. The difference is that in logical, my entities are shown between double quotes ("), while in relational, after the validation, the tables are not between double quotes. Is there a way to overcome this?
