I'm trying to customize the OOB Case entity in CRM 2013. The "Full Name" composite field is required by default, and I would like to add it to my BPF. For whatever reason, this field will not show in the DDM, when I'm editing my BPF. I already confirmed I have the correct entity selected, but it refuses to show up.
Is there a special trick to getting OOB fields to display in the BPF DDM?
