Adding Multiple ontologies to a Data Agent??

I was able to add multiple ontologies to a data agent , but now I could add only one ontology to the data agent and multiple agents. Do we have any documentation supporting this? is the feature of adding multiple ontologies stopped if yes why ..do we have any documentation for that ?

  • You previously attached several ontologies to one Fabric data agent, but the current interface now permits only one. The documentation distinguishes Fabric data agents from the ontology-building agent, so a single-ontology limitation for the latter should not automatically be applied to your scenario. Microsoft’s data-source guidance currently says a data agent can combine up to five sources in any combination and lists ontology as a supported source. However, the ontology integration remains preview, and that statement does not establish why your particular interface changed. Reproduce this in a new test data agent with two accessible ontology items, verify tenant settings and permissions, and capture the exact rejection or disabled control. Compare an existing agent with the new test, without modifying production definitions. Send the workspace, agent identifiers, region, timestamps, and screenshots privately to Fabric support. I found no official retirement explanation that justifies calling this intentional removal.
