I am a newby to NX so I will attempt to explain my issue as clearly as possible.
I have an assembly, and when I select a component and "Make it a Displayed Part" then add a PMI hole callout to a Simple Screw Hole feature and then return to the assembly I get the attached error
After looking at the log file the problem is identified as a Severe Error involving a UGS:
M:bject
In order for me to find out what the missing object is, i need a little context. What is a OM object?
