"Last Enrollment:" field is blank

[yellow]

I'm looking for a way to find all these devices and put them in a Smart Group. Unfortunately the options available for "Last Enrollment" is strictly before/after n date & before/after n days. I can't seem to figure out how to finagle it to report on empty fields.
I'd also settle for where it is in the actual database, but so far my clumsy attempts at finding it in MySQL have been fruitless.

Thanks!

Were you able to find a solution for this? Newly imaged Macs are no longer populating this field, throwing off our FileVault enablement workflow.

No. However in our instance it was only elderly devices that exhibited this issue, as far as I could tell it was never newer devices. In the end I did a lot of manual remediation. But your newly imaged devices SHOULD be populating this. You might want to reach out to your TAM and open a ticket to get this resolved.
