Oracle does not recommend associating drill-through reports that use drill-through Template SQL with Essbase models that support duplicate member names. Essbase Studio generates special tags internally to uniquely identify the duplicate members.
Drill-through target URLs cannot exceed 256 characters in length.
Hierarchies created from Oracle Hyperion EPM Architect, Fusion Edition sources are not supported for drill-through reports.
With Essbase Studio-built cubes, drill-through on a range of cells is not available for Oracle Hyperion Smart View for Office, Fusion Edition or Oracle Essbase Spreadsheet Add-in.
