How to Connect and Use Essbase on-premise Reports within Narrative Reporting?

Summary:

We are using Oracle Cloud EPM and Narrative Reporting to build management reports. There are existing reports and data stored in Essbase on-premise, and the goal is to connect or integrate this Essbase HFR reports directly into Narrative Reporting.

While Narrative Reporting supports data sources like Planning and FCCS, it's unclear how Essbase (standalone or part of EPM) can be used as a source.

We need clarification on:

• Whether Essbase on-premise can be connected directly in Narrative Reporting (for Management Reports or Report Packages).
• If yes, what are the required setup steps (e.g., cube registration, connection setup)?
• If not, what are the recommended alternatives?
