Hi I'd like to know if I can configure an association btw a Change Request and a Service. I have the goal to manage some SLA on Change Request monthly rate for a customer. My assumptions (reading the documentation) are : a) I can define a Service (say service A) b) I can define a SLA (say SLA B) and link it to service A c) After that I can link any ticket to service having an automatic SLA calculation using statistic module If above assumption are corrected, I'd like to modify point c) linking every change request created to service A and calculate the SLA on change final 'successful' status (or other significat status) Unfortunately the 'link' function of Change Request, doesn't show 'Service' as option, so I'll try to find how to configure this option by means of sysConfig options. I found into 'Framework -> Core::LinkObject' one opportunity, adding to PossibleLink###3420 additional relationship btw ITSMChange and Service, similar to relationship btw ITSMWorkorder and Service. Is this approach correct ? If doesn't there is an alternative to meet my goal? regards stefano
