The SO workflow needs to be support day 2 configuration (Modify configuration).
Modify configuration shall be invoked by core NSSMF during scenarios such as shared slice creation, slice activation, slice de-activation etc. In these scenarios S-NSSAI would need to be configured on NFs.
The implementation would need to support PUT operation on serviceInstance API. This work flow would be configured to use the configAssign and configDeploy building blocks which in turn would invoke CDS for generation and application of configurations on NFs.
