Changing the vendor name

Hi to all,

I have question, I just wondering why there is no error in F110 when I change the vendor name.

let say I change the vendor name on 10. 20.2008, then I submitted a proposal on 10.28.2008 the approved on 10.3.2008. then but still the vendor name is old name but no error prompt.

can anyone give a reason why?
