Hello,
We encountered a similar scenario while implementing and testing Sales Order Agent.
One thing we found is that Sales Order Agent runs under its own Agent User, not the logged-in Business Central user's account. Because of that, having the SUPER permission set assigned to the logged-in user doesn't necessarily mean the Agent User has the permissions required to complete the task.
In your case, the error specifically references:
TableData 280003 Address ID Delete: Base Application
I'd recommend checking the following:
-Verify that the required permission sets are assigned to the Sales Order Agent User.
-Review the complete permission error, as it identifies the object that the Agent User cannot access.
-Since the error occurs during Sales Quote → Sales Order conversion, review the permissions required for that business process and confirm the Agent User has access to the referenced Base Application objects.
-As a quick test, temporarily assign the SUPER permission set to the Agent User. If the process succeeds, you've confirmed the issue is permission-related.
We documented this implementation scenario, including permission troubleshooting and supporting screenshots, here:

I hope this helps.
