Hi, Shaun… you might want to take a look at a utility I posted a little while ago. It allows you to scan all documents in a particular directory and get a list of which objects are used. With a little work, you can also get a list of which universes are used.
If you just want to know which universes are used in a document, you can get that from the repository looking at the data provider table. I’ll have to review it and get back with you as to which table that is (or someone else can post it). But if you need the information down to the object level, you need to do that outside of the repository.
Here is the utility I mentioned.
Welcome to Bob!
