Our base schemas are duplicated within many projects. I have a model I want to update but the model was created from the schema APALG (AP is a project, ALG is a base schema), when it should have been RELALG (REL for Release). When I do an update, it identifies everything as a difference. How can I get the update to work based only on the objects, ignoring the owner?
I think the best thing you can do is to open both models and click Model | Schema Assignment and either set schemas to identical values or remove schema assignment from your objects.
You can also merge models, but it would be more complicated than the Schema Assignment option.
