Hello,
Thanks for your question!
If you're an Essential user and trying to raise a support ticket via the Power Platform portal, the system may not recognize your Business Central ID as a valid Premier Support ID, unless your organization has a Premier or Unified Support agreement in place.
Here are a few suggestions:
If none of these options work, I recommend contacting Microsoft Support directly to verify your support entitlement and get help with accessing the correct Premier ID.
Let me know if this helps!
