Nothing. The only difference is less memory so if it fits it works.

If you are using MPLAB with a programmer then you need to change the device. If you are just using the hex file then it will work either way.

hi

is it important to change the code , from this
Code:
list p=16f628
	#include<p16f628.inc>
to this
Code:
list p=16f627
	#include<p16f627.inc>
??

No, there's no real need to, but I would suggest it's a good idea to, so you get used to always using the correct include file.
 
why did they 627 if 628 is already a better one ?

As a cheaper alternative, for smaller applications - it's the exact same device, just with half the program memory.

Personally I've never bought a 627, as I don't see any point in doing so?.
