Hi! I just bought one of these.
CRP-P1009S:
Cook for 10 portions
Minimum cooking size 2 Portions
don't have the yogurt or ferment bread function.
CRP-R0607F:
Cook for 6 portions
You can cook yogurt
have yogurt and ferment bread function.
Note that one portion is more than 100g uncooked rice.
Finding information about these cookers is a challenge. You could try on their American site
