I have mentioned this before but now that DDL import can generate view models (the only mechanism I can see to bring in logical/conceptual models from other tools like PowerDesigner etc)
If the model is successful in that it brings all components it is still not a valid model to deploy to a vdb and start work against.
My proposal is to generate SQL using the column metadata for the view itself.
For example... I've attached a simple ddl but for order_header it'd be like:
SELECT null AS Order_header_id, null AS order_header_name
The primary purpose is to make the model deploy-able immediately.
I'd also like to see this 'feature' at the Model-->Generate stubs when right clicking the model.
