pads not rotors

Can you replace just the pads and not the rotors ?

If the rotor is fine then why do you need to replace the rotor, there is a slight lip though
would this cause a problem

is this also a reason why you replace both ?

The rotors develop ridges on the surface as they wear against the pads. If you put new pads on old rotors the uneven surface causes high pressure spots on the pads that glaze them over and reduce performance and longevity. Historically rotors were resurfaced when replacing pads which eliminated this. But most rotors nowadays are so thin from the factory that this is no longer an option.

txs, but just to confirm the rotor surface is flat (AFAICT) the lip is on the outer edge
