Hello,
Very often our requesters asking me why they was not notified about the Change creation event based on the request which was created by this requester (we use the separate incident type for these sort of requests - "Change request"). It is logical that if requester created the incident with a type "Change request" he has rights to anticipate that this request will be resolved/denied or the Change will be created and associated with this particular request.
Have you intention to add this feature to SD 7.6?
My Regards,
Vlad
