Every leg has its RNP coded in the database, so the entire SID/STAR should be coded with RNP1, the final approach with RNP 0.3 and the missed approach with RNP1. All this is for a standard sequence, a certain procedure might have different RNP required and that should normally be coded in the database.
With FMC U13 you can actually see the coded RNP by pressing DATA on EFIS control panel and it wilk show you the coded RNP for each leg.
