I don't know for sure, and the device registration is generic in GreenLake so it may be attributes used for other products like compute or storage; or it may be there for future use.
If I would need to guess, the tenantWorkspaceId may be something for MSP accounts, where a managed services provider adds the devices and assign them to one of their customers' workspace. But if you see them empty at the moment, I would leave them empty or even try to leave the attribute out when you run your API calls.

Subject: Deleting devices from GreenLake workspace using API
Thank you Herman,
When I look at a device in our workspace (note we do not add our devices to GL, our supplier does) there is a tenantWorkspaceId field but that is blank for all of our devices. I'm just curious about what that is? Do I need to give that any thought? Or should it remain blank and I just add the devices to the new workspace using API Add Devices endpoint once the app and sub have been removed (if so do I need to archive it first)? There is also a field called 'dedicatedPlatformWorkspace' - same question, do I need to worry about that, or just leave it blank?
Thanks for the API link, I have a script now for removing the subscription and application from devices.
