Hi Luca;
Thank you for your reply.
What if I want to exclude class Client from replication? I would for
example replicate everything, but not that particular class (classes)?
Is there anyway to set it up? Or the only way to do it just to list
everything which needs to be replicated, whatever is not in the list will
not get replicated?
Is that correct?
