P4210 to Price History

Hey Everyone,
Does anyone know the business function that P4210 uses to write a Price History Record to P4074-Pricing History? When UPC2, URAT, or EUSE is filled in during Order Creation, the price records are written to F4074. I would like to replicate this when an order is revised. I've been looking at B4200310, but I'm inexperienced in working with P4210 so any help would be appreciated.
