"Metadata Member Not Found" when trying to drill down Member Selection in Smartview 11.1.2.5 for HFM

Hello,

We're testing Smartview 11.1.2.5 with our HFM 9.2 server environment. While many data pulls are working successfully, we get the following error when trying to do a Member Selection, when drilling down:  "Metadata Member Not Found".  This works fine with Smartview 9.2, but we must retire that version of Smartview very soon with the impending End-of-Life for Excel 2003.

Any insight on fixing this is appreciated.

Thanks very much,

Peter
