We have a knowledge base that contains our service desk internal documents as well as those for customers who access/raise tickets via the portal. How do we restrict visibility to customers to see only those articles that are suitable for external viewing? ie customers don't need to see all of our instructions for handling internal maintenance work
We've tried using labels - this stops articles from appearing when a customer is creating a ticket but they can still see them all when searching from the global portal.
We've tried using groups - no luck.
We'd like a single knowledge base rather than having to go down the path of having two. If we have a customer specific KB our service desk team lose access to all of our internal articles and the related knowledge base articles that connect to the service desk tickets.
