What kind of data source? In what part of the product?
@User_MP1OT Please update your display name so we know with whom we are communicating. The latest OAS 2024 supported data sources are listed in the documentation.
If you have an earlier release, let me know and we can attach the PDF version, but as I recall HFM 11.2.4.0 certification goes back to OAS 2022, and RPD data model connections only.
As @Gianni Ceresa mentioned, best to mention the details and the OAS release you are using.
Support for HFM as a data source hasn't changed from initial OAS release. The existing doc for OAS 2024 will be applicable: https://docs.oracle.com/en/middleware/bi/analytics-server/metadata-oas/work-hyperion-financial-management-and-hyperion-planning-data-sources.html#GUID-1E34D320-CFF4-4653-9D1F-3EA860EE1A94
