In GW7 i can customizing the document type property using console1. (GroupWise Utilities > Document Properties Maintenance).
We plan to update GW7 to GW2014. Install test server with GW2014 and our database. I can see users, libraries and documents in GW2014.
But I can't set and modify any additional properties of documents in libraries.

How I can do this in GW2014?

Sorry for bad English.
