Getting closer! Jigs – your suggestions didn’t cause it to work per se but I did set them. It turns out I can add an entry for this field when it’s a local resource. I cannot select an entry for this field when the resource is an enterprise resource.
Essentially, so you know the full picture, I’m trying to add information in the plan for stakeholders. Essentially, I’m adding all of our departments as a General resource and then want to identify them as a “stakeholder” in the resources. I’m essentially trying to great a high level portfolio view for the firm about all projects, teams working on those projects, and stakeholder groups.
