I'm looking to utilize the new Service Registry as a mini CMDB for service requests.
Use case: A "Request new software" SR, where the user picks the software from the Service Registry using the Affected Services field. Then a cascading select (perhaps?) custom field would present a list of available roles for that software.
User selects ApplicationXYZ then a drop down shows up and the requester can select Administrator, General User, Super User, Basic User.
My initial thought is to create a custom cascading select field with the AppName > Available Roles. But I don't know how to associate the Affected Service with the AppName.
Any thoughts on how to do this without requiring a full blown CMDB (Insight)?
