Assign subject staff according to selected target project
You can use issue staffing (see State Transitions) also to delegate responsibilities for work items in common/shared projects to the appropriate/responsible members in other (backend) projects.
An example for such a scenario could be a common "Service Desk" project, that serves as the central/unique entry point for all customer requests (e.g. Request for quotation, Purchase order, Bug reports, Change requests, Support requests, etc).
The help desk staff would only be responsible for receiving, verifying and delegating the request to the appropriate/responsible department (Project), e.g. Sales, Support or Development, where the actual request processing would be handled.
Assigned the request to a specific role, e.g "Consultant"
Optionally, set "Owner" to a specific role, e.g "Manager"
For (backend) project members to be able to access requests and participate in the request processing, they must also be members in the "Service Desk" project (with the same role).
Backend projects can have also own/additional/specific roles and members, but those will not be visible to the "Service Desk".
When delegating a Request to Sales: Janos would become the only request "Manager" and Malte the only "Consultant".
Also only Janos and Malte will receive notifications about the request and will be able to process it (assuming Edit permissions are granted exclusively to the participants "Owner" and "Assigned to" and/or the (staffed) roles "Manager" and "Consultant").
When delegating a Request to Support: Zsolt would become the request "Manager" and Peter the "Consultant".
Klaus, although a Support Consultant, would not be involved (staffed), because he does not have the "Consultant" role in the "Service Desk".
When delegating a Request to Development: Istvan would become the request "Manager" and Akos and Zoltan the "Consultants".
