When setting up a Picklist in a Roadmap, then creating a new Roadmap, unable to see the new Picklist in the section for "All Roadmaps" in the CA Project & Portfolio (PPM) New User Experience (New UX)
Release:
Component: PPMSTU
In order to see a picklist in more than one roadmap item, create a new Lookup in Classic UI, then create an attribute in the Roadmap Item object associated to that lookup. Ensure that an API Attribute ID is entered for the attribute, or the attribute will not show up as a Picklist.
See the Create a Global Custom Picklist section of the New User Experience: Top-Down Planning with Roadmaps documentation for more details on how to do this.
