In the NaaS suite, TMF 656 Service Problem is used to report issues against the Network Service.
Trouble Ticket is meant for End Customer to report the issues with the Customer Services. For e.g. If Customer calls the help desk and they want to report an issue, the issue will be created, investigated and managed in the form of TMF 621 Trouble Ticket.
A sample workflow would be,
Customer calls and reports a Trouble Ticket (TMF 621) against the Customer Service > L1/L2 Support team investigate the Trouble Ticket and found that root cause is with one of the underlying network service > reports a TMF 656 Service Problem with Network Service for resolution
Infrastructure provider identifies an issue with infrastructure > reports as a TMF 656 Service Problem on the Network Services running on the Infrastructure
Hope this clarifies.

Referring to myself: Fools rush in where angels fear to tread . With that prologue, my intuition is that Trouble Ticket is aimed at end-customers or other parties who are not exposed to the CSPs' underlying network and hence not exposed to Service. Additionally, TT could be opened on issues unrelated to Service proper, such as billing complaints, handset problems, etc.
Maybe @Johanne Mayer - as the main NaaS instigator - could comment on this as well.
Hope it helps

Subject: Service Problem vs Trouble Ticket APIs
HI,
Can someone help me understand the difference between the Service Problem Mgt API (TMF656) and the Trouble Ticket API (TMF 621), please?
According to the summary on the OpenAPI table, "The SPM API is used to manage service problems. Service problems are generated based on the information declared by a partner or the event information notified from infrastructure providers." and the Trouble Ticket API "Provides a standardized client interface to Trouble Ticket Management Systems for creating, tracking and managing trouble tickets among partners as a result of an issue or problem identified by a customer or another system".
However, sections 3.2.4-3.2.6 of the API Suite Specification for NaaS (TMF909) seem to indicate that a Consumer would use the SPM API to report problems with their service.
What's the expected differentiation in use between the SPM API and the TT API?
Many thanks
