Good morning Jasleen,
it might depend on how CSDM is used in your current state.
1 - if you have technical services (offerings) for this app support group. In this case you could have a dynamic ci group (if you can think of a query to define all app services in scope) then the support group will be synced to all app services. It requires that the app service will be part of your incident intake.
2 - you might simply define it in the assignment rule logic :
if Business Offering = app... then assign to app support team. In this case you not really using CSDM model.
3 - you could manage your support group data on the Business Service Offering level. Little more work then option 1 but this doesn't require the app service on the intake.
I would choose 3 or 1 and use 2 for the generic routing based on the CSDM model. (so combined)
Mostly used as:
If Configuration Item has support group then use that for initial routing
else
If service offering has support group then use that for initial routing
else
If service has support group then use that for initial routing
else
( regional support)
else
global support
BR,
Barry
