Hi @keith li Thank you for reaching out to us with your concern on Microsoft Q&A forum. Happy to help!
I see that you are trying to perform Arc on-boarding and being blocked with errors. Software inventory is a must to perform Arc Onboarding and to start Software Inventory, user needs to provide server credentials in a step 3 on Panel 2. Please refer to the doc here - https://learn.microsoft.com/en-us/azure/migrate/how-to-discover-applications
If you don't have access to server credentials, then there is no way to start software inventory. You can use Arc for servers to onboard your servers to Arc separately. That experience is also available independent of Azure Migrate appliance.
Hope this helps. Please tag me in your reply if you need further assistance!
