ServiceCatalogItem-Q3: What's the naming used for in the use cases and how does it effect the run-time components? maopeng zhang
The naming fields are used to define if the service instance name is auto-generated by the runtime components (SO and SDNC).
Need to refer to the use case owners to understand if and how these fields are used.
maopeng zhang: ServiceEcompNaming and ecompGeneratedNaming are two flags to indentify whether the ONAP service name auto-generated.
For the user, there are too many parameters to be inputted if using this feature. could it be possible that if namingPolicy is provided and serviceName is empty, the ONAP will auto-generate service name?
