I've expanded all available locations. It's not that I can't find them, I assure you. The problem is that the content package where they're located is simply not visible in any derivation of the BOBJ platform. The view appears in the _SYS_BIC location in HANA Studio, but it is not visible in the same location through the various BOBJ tools in the same location, including Design Studio, Analysis for Excel/OLAP, and Information Design Tool.
Thanks,
Rob
