An embedded object cannot be deleted in isolation

Hi all,

I'm turning to the community for help on this since this is happening at random for over a year after an update the company rolled out on our systems (we're at NX9.0.3.4 MP13).

For some reason when I want to move or delete parts in NX I get an error "an embedded object cannot be deleted in isolation ".

Sometimes a restart helps, sometimes the only thing that helps is going to TCE, remove the item from the BOM and add it again in NX.

This is getting really frustrating, starts costing me a lot of time and is random so I have no way of being pro-active on this as it just happens.

Can someone shed some light on this?

Thanks!
