What can/cannot be requested via a Service Request on the IFS Service Centre

Is there any guidance on the types of requests that can & cannot be made via the IFS Service Centre? We have raised many ‘advice & guidance’ cases as Service Requests and we receive inconsistent responses to them. Sometimes the case owner is very helpful & other times we are told that a Consulting Request is required.

Incidents & Consulting Requests are generally bit easier to define (i.e. it was working previously & now isn’t or seeking expertise to advise on new functionality/capabilities) but there seems to be a bit of a grey area between the around what is/isn’t covered by a Service Request. Some guidance on the limits of support would be useful.
