Introduce a Microservice that allocates deals to SA-CCR Netting Sub-Sets and Hedging Sets.
Sounds like a logical follow-on from the Microservices work already done on Netting Set allocation.
This could be extended to provide any deal-level data needed for the SA-CCR calculation, i.e. Base or Adjusted Notional, Supervisory Duration, Maturity Factor, Delta, etc.
