Reltio Connect

So I'm trying to create a user group that can read and update data from a particular source, but nothing else. However, everything I've tried has either let me edit everything or nothing. Is there a way to do this with the metadata filters?

Thanks

have you tried creating a ruleset where the survivorship strategy is source system and your particular source is the only source in the list?  users in that group would only be able to see data from that source.
