This was broken in a version in 8.1. Very frustrating.

I’m trying to change the parent UDT type of a whole bunch of UDT instances, however I can no longer do this. I know there was a change that was going in at some stage that was going to stop nested UDT instances within a base UDT definition from being changed (makes sense), but this change is affecting the base level as well.

Error is:

Bad_Unsupported("Cannot change typeId of inherited tag

These tank instances below are instantiated within the Tanks folder, and their parent data type is greyed out :frowning: Brings me back to 7.9 days when the parent data type was disabled in the tag editor but you could still export tags, change it in xml and then re-import to overwrite it. However in this recent change in 8.1.4, I can’t even do that… I have to delete the tags first and re-import
