Since I don't see the info currently available in Jamf Pro as built-in Smart Group or Advanced Computer Search criteria I created the following EAs to report the macOS version and deadline date of any pending Declarative Device Management Scheduled Update command. I expect/hope Jamf will add them as eventually, but in the meantime... 

EA script that returns a String Data Type with the version number for any pending DDM scheduled macOS update:

#!/bin/sh DDMSoftwareUpdateInfo="/private/var/db/softwareupdate/SoftwareUpdateDDMStatePersistence.plist" result="No Update Pending" if [ -e "$DDMSoftwareUpdateInfo" ]; then pendingUpdate=$(/usr/bin/defaults read "$DDMSoftwareUpdateInfo" | /usr/bin/grep TargetOSVersion | /usr/bin/cut -d \\" -f 2) if [ -n "$pendingUpdate" ]; then result="$pendingUpdate" fi fi echo "<result>$result</result>"

 

EA script that returns a Date Data Type with the deadline of any pending DDM scheduled macOS update (since returning a non-date formatted result from an EA set for the Date Data Type is a Bad Idea™ this EA returns "2001-01-01 00:00:00" if there is no update scheduled): 

#!/bin/sh DDMSoftwareUpdateInfo="/private/var/db/softwareupdate/SoftwareUpdateDDMStatePersistence.plist" result="2001-01-01 00:00:00" if [ -e "$DDMSoftwareUpdateInfo" ]; then updateDeadline=$(/usr/bin/defaults read "$DDMSoftwareUpdateInfo" | /usr/bin/grep TargetLocalDateTime | /usr/bin/cut -d \\" -f 2 | /usr/bin/tr 'T' ' ') if [ -n "$updateDeadline" ]; then result="$updateDeadline" fi fi echo "<result>$result</result>"

Very nice and thanks for sharing your work, kudos to you. 
I love how we always come together to plug the holes Jamf has't filled yet.
