wow, so sad to see this is a dead thread from 8 years ago. i would really like to export my full set of reusable (global) attributes to have as a backup and source of truth for unintended changes. i'll keep searching...
Not sure I follow the request. Today Definition Exporter does get global enumerations associated with the object type being exported. I just did this today between test and staging 11.2 environments.
You can also export Global Enumerations directly.
Matt, thank you so much for this feedback! I contacted PTC Technical Support yesterday and received the following answer of No: https://www.ptc.com/en/support/article/CS158353
I used your link and ran the export command to get exactly what I was looking for.
My Windchill system has some mismatches between ID and Logical_ID and it was impossible to validate all the attributes from the UI. Now I can post process the XML and cross reference the ID's in Excel.
