Final answer:
Without proper context, it's challenging to define the SRS PCP OAS feature, but typically data would come from financial market data providers or proprietary financial models.
Step-by-step explanation:
I believe the acronym SRS PCP OAS in the question could refer to a feature within a specific software or database system related to financial markets, possibly touching on topics like Securitized Products, Collateralized Debt Obligations (CDOs), or Other Asset-backed Securities (OAS). However, without proper context it is difficult to provide an exact answer. Generally, data for such features would be sourced from financial market data providers, transaction databases, credit rating agencies, or proprietary models developed by financial institutions or software providers.
