Power BI Navigator not showing all Oracle tables - SQL Developer shows them
Environment: - Power BI Desktop: 2.153.910.0 64-bit (April 2026, MSI version) - Oracle Database: 12.1 - Windows 11 Home - Oracle Client: OCMT 64-bit installed **Issue:** When connecting to Oracle ERP database, Power BI Navigator shows only some tables. However: - ✅ SQL Developer (with same credentials) shows ALL tables - ✅ Direct SQL query works: `SELECT * FROM table_name` **What I've tried:** - Cleared local cache (%localappdata%\Microsoft\Power BI Desktop\AnalysisServicesWorkspaces) - Set MaxEvaluationWorkingSetInMB registry to 4096 - OCMT 64-bit reinstall - "Display Options" only shows "Only selected items" and "Enable data previews" - NO "All schemas" option - ODAC installed, TNS_ADMIN set The connection works, but Navigator is not fetching complete schema metadata. Any help would be appreciated!
