ServiceNow’s new Document Management (ds_document) does not support publishing documents to the Knowledge Base, and there is no replacement for the old Knowledge Document plugin or any announced plan to bring that functionality back.

Here’s what you can do today:

• Create the knowledge article manually and upload the file yourself.
• Build a custom Flow Designer or scripted integration if you need automatic publishing.
• Use the legacy Managed Documents module if it's still active in your instance (not a long‑term option).

These are currently the only available workarounds, as ServiceNow provides no built‑in publish‑to‑Knowledge capability for ds_document.

If you find this response helpful, please mark it as Helpful and accept it as the solution if it addresses your question—it would encourage me to contribute more to the ServiceNow Community.
