How to fine empty values in ASA or system manager

[grahamd]

Hello I am trying to find every phone that does not have an entry for coverage path 1. I have tried ASA and system manager.

I have tried nul, null, blank, 0. Nothing seems to work.

Any ideas?

Thanks!

In ASA: List station and sort on cover path. You can export the list to CSV if you have a really long list
