We are unable to create new attributes on the Project object in our new FedRAMP environment. The same issue occurs on NPIO's as well, such as in the Idea and Product objects. When clicking on the New button to create a new attribute, the page refreshes to the same attribute list page instead of loading the attribute create page.
However, attributes are able to be created in other type of objects such as the Cost Plan and Cost Plan Detail objects without an issue.
Release : 15.8.1
Component : CA PPM SAAS STUDIO
Once SSO is enabled on the FedRAMP environment, the issue will no longer occur.
