We link services to accounts. This is working nicely for "Incidents" in self service. Here we only see the Services that are linked to my account.
Still when we have Service Requests, linked to that service, I still see those. I expect that we I'm not covered for a Service I don't see the service under "Incident", bt I also expect that I don't see related Service Requests for that Service.
An idea whould be to show a Service tree for Service requests, instead of Category.
or even better, in a Request definition under 'Entitlement' provide an option to display as part of a linked Service.
